These benchmarks do not rely on MPI or any other non-psm2 protocols to setup or run. Latency, uni-directional bandwidth and bi-directional bandwidth benchmarks are provided. COMPILATION =========== The PSM2 development headers found in the libpsm2-devel package are required to build the benchmarks. There are two ways to acquire the libpsm2-devel: 1. From an Omni-Path Basic or IFS install. 2. By building the PSM2 packages from the opa-psm2 repo (https://github.com/cornelisnetworks/opa-psm2/) with makesrpm.sh or makesdeb.sh. Running 'make' on the command line will produce the following binaries: 1. latency This is a uni-directional latency benchmark. 2. bw-mrate This is a uni-directional bandwidth benchmark. 3. bi-bw-mrate This is a bi-directional bandwidth benchmark. USAGE REQUIREMENTS ================== Two nodes are utilized to run these benchmarks. One node acts as a server and the other will be a client. The only runtime requirement is libpsm2. RUNNING THE BENCHMARKS ====================== All three benchmarks have the same runtime arguments. Example for latency: Server: ./latency Client: ./latency server_hostname BENCHMARK ARGUMENTS: ==================== usage: ./latency [server] [-m size] [-M size] [-f --flush] [-h --help] options: server, server node to connect to, this node will be the client -m, starting message size in bytes (default 1) -M, ending message size in bytes (default 4194304) -f/--flush, flush L3 cache before benchmark --mqstats, show psm2 mq counters -h/--help, show this help message SAMPLE OUTPUT ============= -bash-4.2$ ./latency # PSM2 Ping Pong Latency Test # Message Size(B) Latency(us) 1 xxx.yy 2 xxx.yy 4 xxx.yy 8 xxx.yy 16 xxx.yy 32 xxx.yy 64 xxx.yy 128 xxx.yy 256 xxx.yy 512 xxx.yy 1024 xxx.yy 2048 xxx.yy 4096 xxx.yy 8192 xxx.yy 16384 xxx.yy 32768 xxx.yy 65536 xxx.yy 131072 xxx.yy 262144 xxx.yy 524288 xxx.yy 1048576 xxx.yy 2097152 xxx.yy 4194304 xxx.yy -bash-4.2$ ./bi-bw-mrate # PSM2 Bi-directional Bandwidth, Message Rate Test # Message Size(B) Bandwidth(MB/s) Message Rate(Mmps) 1 xxxxx.yy x.yy 2 xxxxx.yy x.yy 4 xxxxx.yy x.yy 8 xxxxx.yy x.yy 16 xxxxx.yy x.yy 32 xxxxx.yy x.yy 64 xxxxx.yy x.yy 128 xxxxx.yy x.yy 256 xxxxx.yy x.yy 512 xxxxx.yy x.yy 1024 xxxxx.yy x.yy 2048 xxxxx.yy x.yy 4096 xxxxx.yy x.yy 8192 xxxxx.yy x.yy 16384 xxxxx.yy x.yy 32768 xxxxx.yy x.yy 65536 xxxxx.yy x.yy 131072 xxxxx.yy x.yy 262144 xxxxx.yy x.yy 524288 xxxxx.yy x.yy 1048576 xxxxx.yy x.yy 2097152 xxxxx.yy x.yy 4194304 xxxxx.yy x.yy -bash-4.2$ ./bw-mrate # PSM2 Uni-directional Bandwidth, Message Rate Test # Message Size(B) Bandwidth(MB/s) Message Rate(Mmps) 1 xxxxx.yy x.yy 2 xxxxx.yy x.yy 4 xxxxx.yy x.yy 8 xxxxx.yy x.yy 16 xxxxx.yy x.yy 32 xxxxx.yy x.yy 64 xxxxx.yy x.yy 128 xxxxx.yy x.yy 256 xxxxx.yy x.yy 512 xxxxx.yy x.yy 1024 xxxxx.yy x.yy 2048 xxxxx.yy x.yy 4096 xxxxx.yy x.yy 8192 xxxxx.yy x.yy 16384 xxxxx.yy x.yy 32768 xxxxx.yy x.yy 65536 xxxxx.yy x.yy 131072 xxxxx.yy x.yy 262144 xxxxx.yy x.yy 524288 xxxxx.yy x.yy 1048576 xxxxx.yy x.yy 2097152 xxxxx.yy x.yy 4194304 xxxxx.yy x.yy
