Discussion Overview
The discussion centers on the behavior of MCNP5 simulations across different operating systems, specifically comparing performance on a CentOS cluster versus Windows. Participants explore issues related to simulations getting stuck in loops and the implications of parallel processing in MCNP5.
Discussion Character
- Technical explanation, Debate/contested
Main Points Raised
- One participant reports that MCNP5 is stuck in a loop during simulations on CentOS 6.5 with mpich2-1.4.1p, while the same simulations run successfully on Windows with mpich-1.2.4.
- Another participant confirms experiencing the same issue with MCNP5 getting stuck in loops and inquires if a solution has been found.
- A participant suggests that the issue may be related to how MCNP divides problems for parallel processing, indicating that only one process was stuck while others completed their tasks.
- One participant mentions that they allowed the simulation to run for an extended period, which eventually resolved the problem, although another participant states that their simulation did not return to normal even after a long wait.
Areas of Agreement / Disagreement
Participants generally agree that the issue involves MCNP5's handling of parallel processing, but there is no consensus on the effectiveness of letting the simulation run longer as a solution, as experiences vary.
Contextual Notes
Participants have not provided specific details on the configurations or parameters used in their simulations, and there may be missing assumptions regarding the nature of the simulations and the environments in which they are run.
