A suite of communication-intensive proxy applications that mimic commonly found communication patterns in HPC codes. These codes can be used as synthetic codes for benchmarking, or for trace generation using OTF2.
- pairs: all pairs multi-pairs message exchange
- ping-ping: multi-pairs message exchange (user specified pairs)
- spread: k-neighbor communication within rankspace neighborhood
- stencil3d: structured 3D near neighbor pattern like that of jacobi/halo
- stencil4d: structured 4D near neighbor pattern like that of jacobi/halo
- subcom-a2a: FFT-style subcommunicator-based all to all communication
- unstr-mesh: unstructured mesh communication pattern
For OTF2 tracing, see notes here: https://github.com/LLNL/tracer/blob/master/README.OTF
