mochi-quintain is a microservice (i.e., a Mochi provider) that responds to parameterized RPCs to generate synthetic concurrent server load.

The provider portion of mochi-quintain can be started with bedrock.

Bedrock allows us to dynamically configure a service. For example, tests/mochi-quintain-provider.jx9 can be used to deploy a server with five RPC-handling threads

bedrock --jx9 -c tests/mochi-quintain-provider.jx9 --jx9-context "num_rpc_xstreams=5" <protocol>

Or none at all:

bedrock --jx9 -c tests/mochi-quintain-provider.jx9 <protocol>

The primary client is an MPI program that generates a workload for the provider and measures it's performance.

Note that this example assumes that you are running from within the build tree and thus need to set an explicit library path for bedrock to be able to find the provider libraries for quintain.

In one terminal (for a server):

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/carns/working/src/mochi/mochi-quintain/build/src/.libs"

bedrock --jx9 -c ~/working/src/mochi/mochi-quintain/tests/mochi-quintain-provider.jx9 --jx9-context "num_rpc_xstreams=5" na+sm:https://

In another terminal (for a client):

src/quintain-benchmark -g quintain.flock.json -j ../tests/quintain-benchmark-example.json  -o foo
