Problem in running the ALPS (spinmc) code in the parallel mode aith MPI

Have you tried running a simple MPI code that you compiled yourself using the same MPI installation?

You now need to make sure that when building ALPS you use the same MPI version. Are there by any chance multiple MPI versions installed on your machine?

Dear ALPS users, I have used exactly the same compiler links ( /opt/openmpi/1.4.5/gcc/bin/mpicxx ) ( /opt/openmpi/1.4.5/gcc/bin/mpiexec ) as present in the “CmakeCache.txt” configuration file of my ALPS installation to recheck a simple mpi program (monte_carlo_mpi.cpp) and I find that this simple program complies properly and gives a correct parallel execution. but then ALPS does not work in the parallel mode As far as the different versions of mpi are concerned , I found that there are two versions of mpi on navigating the files in my desktop, In the following extract,I have mentioned the specific versions as well sunil@LIN21:~> /opt/openmpi/1.4.5/gcc/bin/mpirun --version mpirun (Open MPI) 1.4.5 sunil@LIN21:~> /usr/lib64/mpi/gcc/openmpi/bin/mpirun --version mpirun (Open MPI) 1.7.2 Please advice, how to go about in solving the mpi paralleization problem with best regards Sunil ________________________________ From: Comp-phys-alps-users [comp-phys-alps-users-bounces@lists.phys.ethz.ch] on behalf of Matthias Troyer [troyer@phys.ethz.ch] Sent: Monday, December 21, 2015 8:27 AM To: comp-phys-alps-users@lists.phys.ethz.ch Subject: Re: [ALPS-users] Problem in running the ALPS (spinmc) code in the parallel mode aith MPI You now need to make sure that when building ALPS you use the same MPI version.

Does that program work?

Dear ALPS users, As per your suggestion, I have tried running a simple MPI program by using the following commands
mpic++ -o monte_carlo_mpi monte_carlo_mpi.cpp
mpirun -np 8 monte_carlo_mpi
I have attached the sample MPI program ( computes PI by the Monte Carlo method) which i have used for checking the MPI. Please suggest me has to how to solve the mpi problem in ALPS simulations.
with best regards Sunil

Have you tried running a simple MPI code that you compiled yourself using the same MPI installation?
