NIXL KVBench

This workload (test_template_name is NIXLKVBench) runs NIXL KV-cache benchmarking for key-value store performance testing.

Test TOML example:

            

            
name = "my_nixl_kvbench_test"
description = "Example NIXL KVBench test"
test_template_name = "NIXLKVBench"

[cmd_args]
docker_image_url = "<docker container url here>"
model = "./examples/model_deepseek_r1.yaml"
model_config = "./examples/block-tp1-pp16.yaml"
backend = "POSIX"
num_requests = 1
source = "file"
num_iter = 16
page_size = 256
filepath = "/data"
        

Test Scenario example:

            

            
name = "nixl-kvbench-test"

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

test_name = "my_nixl_kvbench_test"
