Compiler Options for Profiling
–Mprof=func
Perform routine-level instrumentation-based profiling.
–Mprof=lines
Perform instrumentation-based line-level profiling.
–Mprof=mpich
Use the default MPICH v3 libraries on Linux and OS X for profiling. Implies –
Mmpi=mpich.
–Mprof=mpich1
This option has been deprecated. It continues to direct the compiler to perform MPI profiling
for MPICH1, but only if you set the environment variable MPIDIR to the root of an MPICH1
installation. Implies –Mmpi=mpich1.
–Mprof=mpich2
This option has been deprecated. It continues to direct the compiler to perform MPI profiling
for MPICH2, but only if you set the environment variable MPIDIR to the root of an MPICH2
installation. Implies –Mmpi=mpich2.
–Mprof=msmpi
Perform profiling for Microsoft MSMPI on Windows systems. Implies option –
Mmpi=msmpi.
–Mprof=mvapich1
This option has been deprecated. It continues to direct the compiler to perform MPI profiling
for MVAPICH1, but only if you set the environment variable MPIDIR to the root of an
MVAPICH1 installation. Implies –Mmpi=mvapich1.
–Mprof=sgimpi
Perform profiling for SGI MPI. Implies option –Mmpi=sgimpi.
This option is required even if you compile and link using the SGI MPI mpicc or mpif90 compiler
wrappers.
–Mprof=time
[Linux] Generate a profile using time–based assembly-level statistical sampling. This is
equivalent to using the –pg option, except the profile is saved in a file named pgprof.out
rather than in gmon.out.
–pg
[Linux] Enable gprof-style (sample-based) profiling. Running an executable compiled with
this option produces a gmon.out profile file which contains routine, line, and assembly-level
profiling data.
