EECS 570 Final Project

Building project

• ssh into greatlakes
• clone folder and cd into folder

source env.sh
make

This will create the sgemm executable

Running on Slurm

• from project base directory

sbatch submit.sh

This command will output a job id number and create a file in the project base directory called slurm-<job_id>.out. The .out file will contain all output from the submit.sh script.

Changing submit.sh

Two lines:

./build/sgemm <kernel_number>
./gen_benchmark_results.sh

Only uncomment one line. First line will run individual kernel, second line will run all benchmarks

gen_benchmark_results.sh

Line 11:

for kernel in {1..4}; do

Change {1..4} accordingly to run the benchmarks you want. MUST start at 1.

After running gen_benchmark_results.sh through sbatch run python3 plot_benchmark_results.py to generate plot (DO NOT run python script through Slurm)

Kernel Descriptions

1. Uncoalesced memory access
2. Coalesced memory access
3. Basic shared-memory tiled
4. Async shared-memory tiled (NO overlap)
5. Overlaped async shared-memory tiled (i.e producer-consumer)

Common Slurm commands

View your running jobs

squeue --user=<uniqname>

View running jobs on spgpu partition (spgpu is the Slurm partition with A100 gpus)

squeue --partition=spgpu

View running jobs in EECS 570 class account

squeue --account=eecs570s001wn25_class

View billing information for 570 class

my_account_billing eecs570s001w25_class

Cancel a Slurm job

scancel <job_id>

• When you submit a job using sbatch it will output the job id
• Alternatively you can find the job id using one of the squeue commands above
