No DUMPI binary files generated

[gavahi]

Hi,
When I use DUMPI for collecting trace in NAS Benchmarks, no DUMPI binary files generated. i.e. at IS benchmark, I modified the makefile by adding dumpi to CMPI_LIB :

It can compile and execute the libdumpi_enable_profiling() call in the is.c without any error, but no DUMPI binary files generated.

What platform are you running on? And which compilers are you using?

[gavahi]

CentOS Linux release 7.2.1511
mpicc at mpich.3.2.1

[gavahi]

The DUMPI binary files are generated when running this simple code:

#include <mpi.h>
int main(int argc, char** argv)
{
MPI_Init(&argc, &argv);
MPI_Finalize();
return 0;
}

I compile this code in this way:
mpicc -o test test.c -L/<DUMPI_PATH>/lib -ldumpi

[jjwilke]

Are you definitely compiling the MPI version of the IS test? Traces will not get generated unless there is an MPI_Init and MPI_Finalize call in the code.

Can you also send me the output of a make V=1?

[gavahi]

Both MPI_Init and MPI_Finalize are called in IS. I attached the is.c to this message.
is.txt

This is the output of a make V=1

I changed the position of calling Dumpi at Makfile and it worked.
This is the output of a make V=1. I highlighted the important part at the last line.
