MPI_IO_replay

Replay MPI I/O operation according to the input trace file.

Build

$ mkdir build; cd build;
$ cmake ..
$ make

Note

Important File

The Recorder_All/func_list defines the wrapper function to process

Run

output trace:

$ LD_PRELOAD=Recorder_All/librecorder-compress.so mpirun -np [num] [prog]
$ RECORDER_OUTDIR=<override-dir> LD_PRELOAD=Recorder_All/librecorder-compress.so mpirun -np [num] [prog]

compress trace:

$ src/compress <single log file> <output log file>

merge traces:

$ src/lcs_trace <log_num> <compressed_log_dir> <output_dir>

compressed_log_dir's filename should keep as compressed_log.*, then it would write output into <output_dir> folder.

replay to a c code:

$ src/replay <num> <scale> <single aux file> <func_info> <merged_log_dir> <construct_log_dir> 2>/dev/null 1>temp.c

recompile the temp.c:

$ mpicc -std=c99 -O0 temp.c
