>Anugraha.S I've installed the libopenmpi-dev and also openmpi-bin.I tried to compile a sample program and am getting this error, atom@atom-laptop:~$ mpicc sample.c -o sample sample.c:2:17: error: ompi.h: No such file or directory sample.c: In function 'main': sample.c:7: error: 'mpi_comm_world' undeclared (first use in this function) sample.c:7: error: (Each undeclared identifier is reported only once sample.c:7: error: for each function it appears in.) Am I using the wrong header file? I tried ompic.h too, but the same error.What do i have to do? Thanking in advance, S.Anugraha.
