roco2_kernels -- Kernels from the roco2 workload generator

This repository contains extracted and modernized kernels from the original roco2 for easy integration into diverse experimentation workflows.

The workloads kernels defined by roco2 provide a diverse set of operating points for processors that can aid in helping to verify processor behavior (such as reported power consumption) over a wide range of different operation points.

Running

USAGE: ./kernel_runner [kernel_name] [CPUS] [SECONDS]

• kernel_name: Name of the kernel. See the list of defined kernels below
• CPUS: Set of cpus on which the kernel will be executed. One instance of every kernel is executed on every specified processor core. This accepts range strings in the form of "3-5" or "1,2,3"
• SECONDS: For how long the kernel should be run.

Kernels

• addpd -- SIMD ASM addition
• mulpd -- SIMD ASM multiplication
• sinus -- sin()
• sqrt -- square-root ASM calculation
• blas -- Matrix multiplication using a BLAS library
• busy_wait -- A busy_wait while() loop
• compute -- Manually implemented Matrix multiplication
• firestarter -- FIRESTARTER
• idle -- sleep()
• memory_copy -- memory copy
• memory_read -- memory read
• memory_write -- memory write

Building

Requirements

• A x86-64 or AArch64 processor for the Assembly kernels.
• A cblas implementation. Both OpenBLAS and netlib have been tested.
• Penguinxx requirements:
  • C++ fmtlib (https://github.com/fmtlib/fmt)
• FIRESTARTER requirements:
  • hwloc (https://www.open-mpi.org/projects/hwloc/)

roco2_kernels is dependent on submodules. To be able to build it, be sure you have downloaded them

$ git submodule update --init --recursive

Building is done with cmake:

$ mkdir build
$ cd build
$ cmake ..
$ make

Pre-defined Experiments

experiments/ contains a set of Experiments that can be run using exomat
