CloudAI Benchmark Framework v1.6.1

NIXL CTPerf

This workload (test_template_name is NixlPerftest) runs NIXL performance testing suite for comprehensive network performance evaluation.

Test TOML example:

Copy
Copied!
            

name = "my_nixl_perftest_test" description = "Example NIXL Perftest test" test_template_name = "NixlPerftest" [cmd_args] docker_image_url = "<docker container url here>" subtest = "sequential-ct-perftest" num_user_requests = 1 batch_size = 1 num_prefill_nodes = 1 num_decode_nodes = 1 prefill_tp = 4 decode_tp = 4 isl_mean = 10000 isl_scale = 3000 model = "deepseek-r1-distill-llama-70b"

Test Scenario example:

Copy
Copied!
            

name = "nixl-perftest-test" [[Tests]] id = "perftest.1" num_nodes = 2 time_limit = "00:20:00" test_name = "my_nixl_perftest_test"

Test-in-Scenario example:
