[Pw_forum] Linux cluster

[Jonathan Breeze]

Hello everybody,

I have recently built a linux cluster using diskless nodes.  I have 
patched the kernel with OpenMosix and am now trying to get MPI processes 
to migrate across nodes.  I had heard that it is possible to turn off 
shared memory (which prevents process migration) when compiling LAM-MPI 
using the '--with-rpi=tcp' option.  Unfortunately, I am using MPICH with 
Intel Fortran Compiler.  Any advice on which MPI implementation is best 
to use with PWSCF or accounts of similar experiences would be a GREAT help!

Many thanks.
