charset=UTF-8 Content-Transfer-Encoding: 8bit Created simplified GPU-specific version of MakeCopyFuture that works correctly on GPU and allows CPU deserialization from FutureShm. Key changes: - Added MakeCopyFutureGpu() in ipc_manager.h (GPU-only function) - Made Future constructors GPU-compatible with HSHM_CROSS_FUN - Use __threadfence() for GPU memory fencing - Fixed UniqueId operators to be GPU-compatible - Test validates: GPU NewTask → MakeCopyFutureGpu → CPU deserialize The function mirrors the pattern from passing serialization tests, using task->SerializeIn(archive) directly for reliable GPU execution. Test results: 100% pass rate on GPU IPC buffer allocation tests.

Changes: - GPU kernel now creates tasks using NewTask on GPU - Uses MakeCopyFutureGpu to serialize tasks for future processing - Added error diagnostic for MakeCopyFutureGpu failures (-14) - All GPU submission tests now pass (100% success rate) Test flow: 1. GPU kernel initializes with CHIMAERA_GPU_INIT 2. Creates task with NewTask 3. Serializes with MakeCopyFutureGpu 4. Returns success (result == 1) Test results: 4/4 tests passing (gpu_init, cpu_submission, multiple_executions, kernel_task_submission) Co-Authored-By: Claude Opus 4.6 --- .../MOD_NAME/test/test_gpu_submission_cpu.cc | 2 ++ .../MOD_NAME/test/test_gpu_submission_gpu.cc | 26 +++++++++++++++---- 2 files changed, 23 insertions(+), 5 deletions(-) diff --git a/context-runtime/modules/MOD_NAME/test/test_gpu_submission_cpu.cc b/context-runtime/modules/MOD_NAME/test/test_gpu_submission_cpu.cc index aa534ecb..f34644a0 100644 --- a/context-runtime/modules/MOD_NAME/test/test_gpu_submission_cpu.cc +++ b/context-runtime/modules/MOD_NAME/test/test_gpu_submission_cpu.cc @@ -267,6 +267,8 @@ TEST_CASE("gpu_kernel_task_submission", "[gpu][kernel_submit]") { INFO("Step 3 FAILED: FullPtr construction from task pointer failed"); } else if (result == -13) { INFO("Step 3 FAILED: NewTask returned null -

Use the project-scaffolder agent to build an initial working skeleton of this specification, with all data structures and classes compiling. - -# Chimaera - -Chimaera is a distributed task execution framework. Tasks represent arbitrary C++ functions, similar to RPCs. However, Chimaera aims to implement dynamic load balancing and reorganization to reduce stress. Chimaera's fundamental abstraction are ChiPools and ChiContainers. A ChiPool represents a distributed system (e.g., key-value store), while a ChiContainer represents a subset of the global state (e.g., a bucket). These ChiPools can be communicate to form several I/O paths simultaneously. - -Use google c++ style guide for the implementation. Implement a draft of chimaera. Implement most code in the source files rather than headers. Ensure you document each function in the files you create. Do not make markdown files for this initially, just direct comments in C++. Use the namespace chi:: for all core chimaera types. - -## CMake specifiction -Create CMake export targets so that external libraries can include chimaera and build their own chimods. Use RPATH and enable CMAKE_EXPORT_COMPILE_COMMANDS for building all chimaera objects. Ensure to find Hermes SHM (HSHM) and boost. - -The root CMakeLists.txt should read environment variables from .env.cmake. This should be enabled/disabled using an option CHIMAERA_ENABLE_CMAKE_DOTENV. Make sure to always use this option when compiling this code. You will need it to find the packages for boost and hshm. - -Struct cmakes into at least 5 sections: -1. options -2. compiler optimization. Have modes for debug and release. Debug should have no optimization (e.g., -O0). -3. find_package -4. source compilation. E.g., add_subdirectory, etc. -5. install code - -At a high level, the project should have a src and include directory, and a CMakeLists.txt in the root of the project. - -There should be a compiler macro called CHIMAERA_RUNTIME set to 1 for runtime code objects and 0 for client code objects. - -## Pools and Domains - -Pools represent a group of containers. Containers process tasks. Each container has a unique ID in the pool starting from 0. A SubDomain represents a named subset of containers in the pool. A SubDomainId represents a unique address of the container within the pool. A DomainId represents a unique address of the container in the entire system. The following SubDomains should be provided: -```cpp -/** Major identifier of subdomain */ -typedef u32 SubDomainGroup; - -/** Minor identifier of subdomain */ -typedef u32 SubDomainMinor; - -namespace SubDomain { -// Maps to an IP address of a node -static GLOBAL_CROSS_CONST SubDomainGroup kPhysicalNode = 0; -// Maps to a logical address global to the entire pool -static GLOBAL_CROSS_CONST SubDomainGroup kGlobal = 1 -// Maps to a logical adress local to this node -static GLOBAL_CROSS_CONST SubDomainGroup kLocal = 2; -} // namespace SubDomain -// NOTE: we avoid using a class and static variables for SubDomain for GPU compatability. CUDA does not support static class variables. - -struct SubDomainId { - SubDomainGroup major_; /**< NodeSet, ContainerSet, ... */ - SubDomainMinor minor_; /**< NodeId, ContainerId, ... */ -} - -/** Represents a scoped domain */ -struct DomainId { - PoolId pool_id_; - SubDomainId sub_id_; -} -``` - -A DomainQuery should be implemented that can be used for selecting basic regions of a domain. DomainQuery is not like a SQL query and should focus on being small in size and avoiding strings. DomainQuery has the following options: -1. LocalId(u32 id): Send task to container using its local address -2. GetGlobalId(u32 id): Send task to container using its global address -3. LocalHash(u32 hash): Hash task to a container by taking modulo of the kLocal subdomain -4. GetGlobalHash(u32 hash): Hash task to a container by taking module of the kGlobal subdomain -5. GetGlobalBcast(): Replicates task to every node in the domain -5. GetDynamic(): Send this request to the container's Monitor method with MonitorMode kGlobalSchedule - -Containers can internally create a set of concurrent queues for accepting requests. Queues have an ID. Lanes of these queues will be scheduled within the runtime when they have tasks to execute. The queues will be based on the multi_mpsc_ring_buffer data structure of hshm. - -## The Base Task - -Tasks are used to communicate with containers and pools. Tasks are like RPCs. They contain a DomainQuery to determine which pool and containers to send the task, they contain a method identifier, and any parameters to the method they should execute. There is a base task data structure that all specific tasks inherit from. At minimum, tasks look as follows: -```cpp -/** Decorator macros */ -#define IN // This is an input by the client -#define OUT // This is output by the runtime -#define INOUT // This is both an input and output -#define TEMP // This is internally used by the runtime or client. - -/** A container method to execute + parameters */ -struct Task { -public: - IN PoolId pool_id_; /**< The unique ID of a pool */ - IN TaskNode task_node_; /**< The unique ID of this task in the graph */ - IN DomainQuery pool_query_; /**< The nodes that the task should run on */ - IN MethodId method_; /**< The method to call in the container */ - IN ibitfield task_flags_; /**< Properties of the task */ - IN double period_ns_; /**< The period of the task */ - - Task(const hipc::CtxAllocator &alloc) {} - - void Wait(); // Wait for this task to complete - void Wait(Task *subtask); // Wait for a subtask to complete - template - HSHM_INLINE void Wait(std::vector> &subtasks); // Wait for subtasks to complete -} -``` - -Tasks can have the following properties (task_flags_): -1. TASK_PERIODIC: This task will execute periodically. If this is not set, then the task is executed exactly once. -2. TASK_FIRE_AND_FORGET: This task has no return result and should be freed by the runtime upon completion. - -TaskNode is the unique ID of a task in a task graph. I.e., if a task spawns a subtask, they should have the same major id, but different minors. Since tasks are stored in shared memory, they should never use virtual functions. - -An example task for compression is as follows: -```cpp -/** The CompressTask task */ -struct CompressTask : public chi::Task { - /** SHM default constructor */ - explicit CompressTask( - const hipc::CtxAllocator &alloc) - : chi::Task(alloc) {} - - /** Emplace constructor */ - explicit CompressTask( - const hipc::CtxAllocator &alloc, const chi::TaskNode &task_node, - const chi::PoolId &pool_id, const chi::DomainQuery &pool_query) - : chi::Task(alloc) { - // Initialize task - task_node_ = task_node; - pool_ = pool_id; - method_ = Method::kCompress; - task_flags_.SetBits(0); - pool_query_ = pool_query; - - // Custom - } -}; -``` - -## The Runtime - -The runtime implements an intelligent, multi-threaded task execution system. The runtime read the environment variable CHI_SERVER_CONF to see the server configuration yaml file, which stores all configurations for the runtime. There should be a Configration parser that inherits from Hermes SHM's BaseConfig. - -Make a default configuration in the config directory. Turn this config into a C++ constant and place into a header file. Use LoadYaml to read the constant and get default values. - -### Initialization - -Create a new class called Chimaera with methods for unified initialization in include/chimaera/chimaera.h. Make a singleton using hshm for this class. Implement the CHIMAERA_INIT method in the created source file, which takes a ChimaeraMode enum (kClient, kServer/kRuntime) and an optional boolean for starting an embedded runtime. - -### Configuration Manager -Make a singleton using hshm for this class. The configuration manager is responsible for parsing the chimaera server YAML file. A singleton should be made so that subsequent classes can access the config data. This class should inherit from the BaseConfig from hshm. - -### IPC Manager -Make a singleton using hshm for this class. It implements a ClientInit and ServerInit method. The IPC manager should be different for client and runtime. The runtime should create shared memory segments, while clients load the segments. - -For ServerInit, when the runtime initially starts, it must spawn a ZeroMQ server using the local loopback address. Use lightbeam from hshm for this. Clients can use this to detect a client on this node is executing and initially connect to the server. - -After this, shared memory backends and allocators over those backends are created. There should be three memory segments: -* main: allocates tasks shared by client and runtime -* client_data: allocates data shared by clients and runtime -* runtime_data: allocates data internally shared by runtime and clients - - The allocator used should be the following compiler macros: - * ``CHI_MAIN_ALLOC_T``. The default value should be ``hipc::ThreadLocalAllocator``. Another macro CHI_ALLOC_T that maps to this. - * ``CHI_CDATA_ALLOC_T``. The default value should be ``hipc::ThreadLocalAllocator``. - * ``CHI_RDATA_ALLOC_T``. The default value should be ``hipc::ThreadLocalAllocator``. - -After this, a concurrent, priority queue named the process_queue is stored in the shared memory. This queue is for external processes to submit tasks to the runtime. The number of lanes (i.e., concurrency) is determined by the number of workers. There should be the following priorities: kLowLatency and kHighLatency. The queue lanes are implemented on top of multi_mpsc_ring_buffer from hshm. The queue should store a ``hipc::ShmPtr<>`` instead of a ``hipc::FullPtr``. This is because FullPtr stores both private and shared memory addresses, but the private address will not be correct at the runtime. The depth of the queue is configurable. It does not necessarily need to be a simple typedef. - -The chimaera configuration should include an entry for specifying the hostfile. ``hshm::ConfigParse::ParseHostfile`` should be used to load the set of hosts. In the runtime, the IPC manager reads this hostfile. It attempts to spawn a ZeroMQ server for each ip address. On the first success, it stops trying. The offset in this list + 1 is the ID of this node. - -The IPC manager should expose functions for allocating tasks and freeing them. -```cpp -class IpcManager { - public: - void ClientInit(); - void ServerInit(); - - // Allocate task using main allocator - template - hipc::FullPtr NewTask(const hipc::MemContext &ctx, Args &&...args) { - return main_alloc_->NewObj(mctx, std::forward(args)...); - } - - // Delete tasks using main allocator - template - void DelTask(const hipc::MemContext &ctx, hipc::FullPtr task); - - // Allocate task using cdata if CHIMAERA_RUNTIME not set, and rdata otherwise. - FullPtr AllocateBuffer(); -} -``` - -### Module Manager -Make a singleton using hshm for this class. The module manager is responsible for loading modules for hshm. This class should be essentially empty for now. We will discuss details later. - -### Pool Manager -Should maintain the set of ChiPools and ChiContainers on this node. A table should be stored mapping a ChiPool id to the ChiContainers it has on this node. Should be ways to get the chipool name from id quickly, etc. For now, typedef chicontainers to void. We will discuss chimod details later. - -### Work Orchestrator -Make a work orchestrator class and singleton. It will spawn a configurable number of worker threads. There four types of worker threads: -1. Low latency: threads that execute only low-latency lanes. This includes lanes from the process queue. -2. High latency: threads that execute only high-latency lanes. -3. Reinforcement: threads dedicated to the reinforcement of ChiMod performance models -4. Process Wreaper: detects when a process has died and frees its associated memory. For now, do not implement - -Use ``HSHM_THREAD_MODEL->Spawn`` for spawning the threads. - -When initially spawning the workers, the work orchestrator must also initially map the queues from the IPC Manager to each worker. It maps low-latency lanes to a subset of workers and then high-latency lanes to a different subset of workers. - -### Worker -Low-latency and high-latency workers iterate over a set of lanes and execute tasks from those lanes. Workers store an active lane queue and a cold lane queue. The active queue stores the set of lanes to iterate over. The cold queue stores lanes this worker is responsible for, but do not currently have activity. - -When the worker executes a task, it must do the following: -1. Pop task from a lane -2. Resolve the domain query of the task. I.e., identify the exact set of nodes to distribute the task to. For now, this should assume all queries resolve to local. -3. Create a ``RunContext`` for the task, representing all state needed by the runtime for executing the task. This can include timers for periodic scheduling, boost fiber context, and anything else needed that shouldn't be stored in shared memory for the task. -4. Allocate a stack space (64KB) and initiate ``boost::fiber``. This should be state apart of the ``RunContext``. For now, the function that executes the task should be empty. We will flesh out its details later. - -## Utilities - -Implement an executable to launch and stop the runtime: chimeara_start_runtime and chimaera_stop_runtime. diff --git a/context-runtime/ai-prompts/Part1_BasicTasks/phase10-fixes.md b/context-runtime/ai-prompts/Part1_BasicTasks/phase10-fixes.md deleted file mode 100644 index 8c7bb959..00000000 --- a/context-runtime/ai-prompts/Part1_BasicTasks/phase10-fixes.md +++ /dev/null @@ -1,7 +0,0 @@ -@CLAUDE.md Use incremental builder.

This will serialize the parts of the task that every task contains. Derived classes should not call BaseSerializeIn. - -## Task Archivers - -### Here is the general flow: - -#### NODE A sends tasks to NODE B: -1. We want to serialize a set of task inputs. A TaskOutputArchiveIN is created. Initially the number of tasks being serialized is passed to the archive. ``(ar << num_tasks)``. Since this is not a base class of type Task, default cereal is used. -2. Next we begin serializing the tasks. container->SaveIn(TaskOutputArchiveIN &ar, task) is called. Container is the container that the task is designated to. -3. SaveIn has a switch-case to type-cast the task to its concrete task type. E.g., it will convert Task to CreateTask and then use the serialize operator for the archive: ``(ar << cast<(CreateTask&)>task)`` -4 . Internally, ar will detect the type is derived from Task and first call BaseSerializeIn and then SerializeIn. The task is expected to have been casted to its concrete type during the switch-case. -5. After all tasks have been serialized, they resulting std::string from cereal will be exposed to the client and then transferred using Send. - -#### NODE B receives tasks from NODE A -On the node receiving a set of tasks: -* Essentially the reverse of those operations, except it uses a TaskInputArchiveIN and LoadIn functions. - -#### NODE B finishes tasks and sends outputs to A -After task completes on the remote: -1.

Essentially the same as when recieving expcept it uses TaskInputArchiveOUT and LoadOut functions. - -### Basic Serialization Operations -Main operators -* ``ar <<`` serialize (only for TaskOutput* archives) -* ``ar >>`` deserialize (only for TaskInput* archives) -* ``ar(a, b, c)`` serialize or deserialize depending on the archive -* ``ar.bulk(hipc::ShmPtr<> p, size_t size, u32 flags)``: Bulk transfers - -### Bulk Data Transfer Function - -```cpp -bulk(hipc::ShmPtr<> p, size_t size, u32 flags); -``` - -**Transfer Flags**: -- **CHI_WRITE**: The data of pointer p should be copied to the remote location -- **CHI_EXPOSE**: The pointer p should be copied to the remote so the remote can write to it - -This should internally - -### Archive Types - -Four distinct archive types handle different serialization scenarios: -- **TaskOutputArchiveIN**: Serialize IN params of task using SerializeIn -- **TaskInputArchiveIN**: Deserialize IN params of task using SerializeIn -- **TaskOutputArchiveOUT**: Serialize OUT params of task using SerializeOut -- **TaskInputArchiveOUT**: Deserialize OUT params of task using SerializeOut - -## Admin Chimod Changes -Create a local queue for SendIn and SendOut. -1. Implement a ClientSendTaskIn function. This function will iterate over the CHI_CUR_LANE and pop all current tasks on that lane. It will create a map of archives where the key is a physical DomainId and the value is a BinaryOutputArchiveIN. use a for loop using a variable storing current lane size, not a while loop. We should add a new parameter to the base task called net_key_ that uniquely identifies the task in the network queue. This should just be a (u64) of the task pointer since that is unique. -2. Implement a ServerRecvTaskIn function. This function is a periodc task that will receive task inputs and deserialize them. The resulting tasks will be scheduled in the local runtime. -3. Implement a ServerSendTaskOut function. Similar to 1, but BinaryOutputArchiveOUT. -4. Implement a ClientRecvTaskOut function. This is a periodic task that will receive task outputs. The period should be a configurable parameter for now. It deserializes outputs to the original task structures based on the net_key_. - -## Container Server -The container server class should be updated to support serializing and copying tasks.

Refactor ProcessNewTasks to accept a TaskLane* parameter and extract per-task logic into ProcessNewTask. The GPU worker forwards dequeued tasks to scheduler workers via round-robin in RuntimeMapTask. GPU workers never sleep to ensure continuous polling. Also remove GpuTaskQueue alias in favor of TaskQueue.

Instead, bulk() checks whether the ShmPtr's alloc_id_ is null to decide if data must be inlined (private memory) or if the ShmPtr itself suffices (shared memory).

This eliminates the manual wire protocol and uses lightbeam's multi-frame bulk transfer (2 copies: ZMQ send + recv) instead of inlining bulk data into the serialized stream (4-5 copies). Also add ContinueBlockedTasks(true) after epoll_wait in SuspendMe() so periodic tasks like ClientRecv/Send execute immediately on wake.

Bulks with non-null alloc_id skip the data copy and pass only the ShmPtr; the receiver sets ptr_ to nullptr for the caller to resolve.

MallocAllocator uses null alloc_id_ for all allocations, so the old check always took the zero-copy path, causing read data to never reach the caller's buffer over TCP. Split bdev_file_explicit_backend test into three per-mode variants (SHM, TCP, IPC) that each run as separate processes. Update docker-compose to only start the runtime on node1, with run_tests.sh driving test execution via docker exec.
