Hello all. I was curious as to whether the native Linux ubuntu installation of OpenMC would enjoy a performance advantage over a WSL2 Ubuntu installation. I found that the WSL2 Ubuntu installation actually ran a bit faster. On the attached Jupyter notebook, the native Linux version of OpenMC generated more text window output during depletion runs than the WSL did, which is the only difference to which I can chalk up the difference. One important caveat - ensure that your ENDFB file library is copied into the Linux WSL directory and not in the windows directory structure. When in the Windows directory, it accesses those file reads painfully slowly.
Native Ubuntu Linux: 443.8 seconds
WSL/Ubuntu: 421.9 seconds
Your mileage may vary, but I think it is more than fair to say that running OpenMC under WSL2/Ubuntu does not result in any performance penalty.
Test Jupyter Notebook file attached.
