OSU

This workload (test_template_name is OSUBench) allows you to execute OSU Micro Benchmarks within the CloudAI framework.

Test example:

            

            
name = "osu_example"
test_template_name = "OSUBench"
description = "OSU Benchmark example"

[cmd_args]
"docker_image_url" = "<docker container url here>"
"benchmarks_dir" = "/directory/with/osu/binaries/in/container"
"benchmark" = ["osu_allreduce", "osu_allgather"]
"iterations" = 10
"message_size" = "1024"
        

Test Scenario example:

            

            
name = "osu_example"

[[Tests]]
id = "Tests.1"
test_name = "osu_example"
num_nodes = "2"
time_limit = "00:20:00"
        

Test-in-Scenario example:

            

            
name = "osu-test"

[[Tests]]
id = "Tests.osu_allreduce"
num_nodes = 2
time_limit = "00:05:00"

name = "osu_example"
description = "OSU allreduce 1KB"
test_template_name = "OSUBench"

    [Tests.cmd_args]
    docker_image_url = "<docker container url here>"
    benchmarks_dir = "/directory/with/osu/binaries/in/container"
    benchmark = "osu_allreduce"
    iterations = 10
    message_size = "1024"
