NIXL Bench#

This workload (test_template_name is NIXLBench) runs NIXL benchmarking suite for network and interconnect performance testing.

Usage Examples#

Test TOML example:

name = "my_nixl_bench_test"
description = "Example NIXL Bench test"
test_template_name = "NIXLBench"

[cmd_args]
docker_image_url = "<docker container url here>"
path_to_benchmark = "/workspace/nixlbench/build/nixlbench"
backend = "UCX"
initiator_seg_type = "VRAM"
target_seg_type = "VRAM"
op_type = "READ"

Test Scenario example:

name = "nixl-bench-test"

[[Tests]]
id = "bench.1"
num_nodes = 1
time_limit = "00:10:00"

test_name = "my_nixl_bench_test"

Test-in-Scenario example:

name = "nixl-bench-test"

[[Tests]]
id = "bench.1"
num_nodes = 1
time_limit = "00:10:00"

name = "my_nixl_bench_test"
description = "Example NIXL Bench test"
test_template_name = "NIXLBench"

  [Tests.cmd_args]
  docker_image_url = "<docker container url here>"
  path_to_benchmark = "/workspace/nixlbench/build/nixlbench"
  backend = "UCX"
  initiator_seg_type = "DRAM"
  target_seg_type = "DRAM"
  op_type = "WRITE"
