NIXL CTPerf

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

Test TOML example:

            

            
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:

            

            
name = "nixl-perftest-test"

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

test_name = "my_nixl_perftest_test"
