MCNP5 Installation Help for Scientific Linux & CentOS | Rocks Cluster Guide

In summary, the conversation is about the difficulty of compiling MCNP5 on Scientific Linux or CentOS, particularly with the MPI version. The errors are in the dotcomm modules and are due to poor comparison statements or improper use of Switch statements. The person had some success with the Sequential version on CentOS but encountered errors with the MPI version. They have attached a screenshot of the Terminal and are seeking help. The image is broken, but they later state that they have solved the problem by changing the default MPI environment. They used GCC 4.4.7 and MPICH2-1.4.1p1 for compiling.

Hello,

Is there anyone who has any experience of installing (compiling) MCNP5 on Scientific Linux or CentOS?
Previously I had used MCNP5 on Windows. But Recently I thought of moving to Linux based cluster.

But I am having difficulty in compiling MCNP5 on Linux. The environment that I am using for clustering is Rocks Cluster.

Regards,

I had some success in compiling Sequential version of MCNP5 on CentOS.
But MPI version is giving errors. And it looks like all the errors are in dotcomm modules and all the error are either because of poor comparison statements OR because of improper use of Switch statements.
I have attached a screenshot of Terminal.
Any help in this regard will be appreciated.

The image is broken.
I also installed mcnp5.mpi on linux and got errors at testing phase.
But I guess our mistakes are different but maybe I can help you.

Thanks, I solved my problem. It was because of the default MPI environment loaded on Rocks Cluster.
Once I changed that it compiled successfully.
