This looks like a problem with your MPI installation since it crashes in MPI_Init. Did you try to compile and run a simple MPI program?

Dear Alps users, I have installed ALPS2.2 on my local machine containing 12 processing units. I have tried running a simple tutorial given in the alps examples files. when i am using the following command "pyalps.runApplication('spinmc',input_file,Tmin=5)" , everything works fine and the ALPS program runs (Serial mode) and gives the proper output as expected. On the other hand when i use the command "pyalps.runApplication('spinmc',input_file,Tmin=5,MPI=7)" , i am getting a lot of error messages related to segmentation fault. The error messages are as follows:

mpirun noticed that process rank 1 with PID 4682 on node LIN21 exited on signal 11 (Segmentation fault).
I am very kindly requesting the ALPs users to help me out in solving the above mentioned issue. I am looking forward for your suggestions to overcome this problem.
with best regards Sunil
