Trace Replay and Network Simulation Framework
TraceR seems to implement MPI_Barrier as a zero-byte allreduce (https://github.com/hpcgroup/TraceR/blob/develop/tracer/reader/otf2_reader.C#L583 ), which seems like a reasonable implementation. However, at least the fat tree model of CODES, doesn't handle zero byte...
The qos features developed by Lee Savoie are merged. The corresponding updates to CODES are implemented in this PR: https://github.com/codes-org/codes/pull/210
Initial changes for calculation of computation time in a trace. More Verifications with traces pending.
Runs stencil4d-otf example using the dragonfly, fattree, and hypre, and torus network configurations, and compares the resulting output files to a baseline set of output files. - Some times check...
…ml file which is a quartz topology and test.xml which is a small topology for testing
Some open issues with the tutorials from the HOTI slides (22-39, 43-53): - The network models section seems to be from the CODES wiki, so I included a link at...
This adds support for building the main TraceR executable with CMake. A first pass has been made at supporting a sphinx doc build target and running the tests using ctest....
SCOREP_USER_REGION_BY_NAME_BEGIN( "TRACER_WallTime_Test" , SCOREP_USER_REGION_TYPE_COMMON); usleep(10); SCOREP_USER_REGION_BY_NAME_END("TRACER_WallTime_Test"); I expect that it TraceR would output: [ 0 0 : Begin TRACER_WallTime_Test x ] [ 0 0 : End TRACER_WallTime_Test x+.00001 ] Where...
The mkdir call when an lp-io-dir is given only creates directories one level deep -- if all of the parent directories don't exist it gives an error. (This may be...
