Hi Ken,

I did some test and MPICH seems to be working OK, at least I ran the CPI example and worked fine.

However, I have problems running an 'n' process CPI job on multiple nodes. It seems I have not created a machinefile yet to succeed. Is this step absolutely necessary?

Yes, if you manage the cluster yourself.

Moreover, my problem running WRF still exists, because the libmpich.so.10 file is not successfully created when installing MPICH 3.0.4.

Looked at your c.txt, and found  "checking whether to build shared libraries... no"

Could you add --enable-shared=yes to configure when building mpich. That is the default but I don't know why it was not enabled in your build. 

I'm attaching all the configure.log files from my installation as well as the output from mpiexce -info

Your help is greatly appreciated.

Can you confirm your MPICH installation working correctly? Have you tried compiling and running the cpi.c program from the examples directory from the tarball?

The MPICH 3.0.4 installation should contain a libmpich.so.10 file, so it will be helpful to know things are installed and working well.

Hi all,

I´m trying to run WRF for which I´m using mpich libraries. I recently
installed mpich-3.0.4 and mpich-3.1.4 (with ifort) hoping to install the
libmpich.so.10 file, but neither of them have it ,and I always got this
error

./real.exe: error while loading shared libraries: libmpich.so.10: cannot
open shared object file: No such file or directory

I searched in the mpich folders: /usr/local/lib and
/usr/local/bin/mpich, but cannot find the file

any help will be appreciated

Jorge
