Mochi-quintain https://github.com/mochi-hpc/mochi-quintain Includes a provider that can be embedded in other services, via Mochi-bedrock or other means, to provide synthetic workload testing capability (i.e., “self-test”) Includes an MPI benchmark that can be used to issue parameterized RPCs to the quintain provider from a large number of concurrent clients to measure response times from a heavily loaded server Some preliminary plotting tools to help understand response time distributions and tail latency
Example distribution of response times for a Quintain provider under load. Software updates
