[ESPResSo] parallel computing

[Mikheil Azatov]

Hi,

I'm very new to parallel computing and know very little about it so far. I installed lam 7.1.4 on my computer and tried building espresso (--with-mpi=MPI option) but i got a lot of errors like this: 

maggs.c:(.text+0x190be): undefined reference to `ompi_mpi_comm_world'

maggs.c:(.text+0x190e4): undefined reference to `MPI_Irecv'

maggs.o: In function `prepare_surface_planes':

I also tried installing openmpi but got the same...

I was wondering if anyone could help me to make parallel computing work, or maybe show me the manual of how to do this. Any help would be really appreciated because I don't even know where to start.

I was thinking first to make both CPU's on my computer work together and then try running on several computers.

Thanks a lot,
