[Pw_forum] OpenMPI on mac
Hi, I am new with Macs. I am learning to compile in it. Frankly, I have been happy after installing fink, so I am still Linux minded. I installed g95, and with it I could compile QE serially. The problem is to use mpif90. There is an mpif90 that comes with Xcode version 3, but it is not configured. When I run it I have this message. Macintosh:Developer eariel$ mpif90 -- Unfortunately, this installation of Open MPI was not compiled with Fortran 90 support. As such, the mpif90 compiler is non-functional. Obviously I would have to configure it, but I do not find any file named configure. Is there an option to reconfigure it within Xcode, without downloading OpenMPI independently of Xcode? Other question, is there a gfortran in Xcode? How to install it? Thanks -- Eduardo Menendez -- next part -- An HTML attachment was scrubbed...

How to install it? I used binaries here: http://gcc.gnu.org/wiki/GFortranBinaries .

Hi everyone, i'm starting in these days to setup a little cluster (well, just two intel mac dual core, osx 10.5.2) to learn how parallel processing works. I'm working with the espresso version 4.0 and i have Intel Fortran compiler (v10) and gcc from the developers tools (xcode 2.5, gcc 4.01) on both the machines. I downloaded and compiled OpenMPI and i'm pretty sure it works fine on both computer (i tried with a very simple program from the openmpi website). Now i tried to compile QE with all the wrappers (mpif90, mpicc, mpicxx, mpif77) in the make.sys, at least that's what the openmpi suggests to do in their FAQ. The compilation runs perfectly but when i try to run a simple simulation the programs fails with this error message *** An error occurred in MPI_Comm_f2c *** before MPI was initialized *** MPI_ERRORS_ARE_FATAL (goodbye) [rikis-macbook.local:56606] Abort before MPI_INIT completed successfully; not able to guarantee that all other processes were killed! The command i use is mpirun -np 2 $PWROOT/bin/pw.x < si.scf.in and i run it on just one mac (my laptop). To be precise i can see two times the error, as if both the processes break for the same problem. I understood the problem is the fortran-c handler but i really have no idea how to fix this. I haven't worked yet on the real cluster but i think if it's not working with the dual core alone no hope with the rest Waiting for your news, thanks a lot for the help.

Ricardo- I don't have experience with your configuration, however, I can tell you that openmpi 1.2.4 installed via macports worked fine when I compiled 4.0 with g95 on my Mac. If all else fails you can try that configuration.
