eztrace.preload - performance analysis tool
eztrace.preload [OPTION] COMMAND_LINE
Run COMMAND_LINE and generate an execution trace.
$ eztrace.preload -t "memory pthread" ./my_program param1 param2
For MPI programs:
$ mpirun -np 2 `eztrace.preload -m ./my_program` param1 param2
eztrace.preload is a fallback launcher for eztrace. It relies on LD_PRELOAD for interception function calls. Thus, it only works for shared libraries.
