Quarterly newsletter, January 2022

New microservices

  • 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.
