Discussion Overview
The discussion revolves around the challenges of installing and compiling MCNP5 on Scientific Linux and CentOS, specifically within a Rocks Cluster environment. Participants share their experiences, errors encountered, and potential solutions related to both the sequential and MPI versions of the software.
Discussion Character
- Technical explanation
- Debate/contested
Main Points Raised
- One participant reports difficulty in compiling MCNP5 on Linux after previously using it on Windows, seeking assistance from others.
- Another participant mentions success with the sequential version of MCNP5 on CentOS but encounters errors with the MPI version, attributing these errors to issues in dotcomm modules related to comparison and switch statements.
- A third participant confirms they also faced errors during the testing phase of mcnp5.mpi installation, suggesting that their mistakes may differ from those of the first participant.
- One participant resolves their issue by changing the default MPI environment on the Rocks Cluster, leading to successful compilation.
- There is a query regarding the specific compiler and MPI versions used by participants, with one participant sharing they used GCC 4.4.7 and MPICH2-1.4.1p1.
Areas of Agreement / Disagreement
Participants express a mix of experiences with compiling MCNP5, with some finding success while others continue to face challenges. There is no consensus on a single solution, as different participants report varying issues and resolutions.
Contextual Notes
Limitations include potential dependencies on specific configurations of the Rocks Cluster and variations in the MPI environment that may affect compilation outcomes.
