STAR-CCM+ NOTE on license tunnels Use 1999@chpclic1 for the license, the dtn node is not currently available for this. New procedure for versions from 19.02.009 onwards There has been a major change to the underlying dependencies of versions of STAR-CCM+ released from 2024, starting with 19.02.009. Specifically, the software now requires glibc-2.28 or higher. This is not compatible with the CentOS-7 operating system used on the Lengau cluster. The workaround is to package the software ins…

Those that have been developed on other operating systems generally also have build configurations for Linux. However, there are some applications that are only available on Windows. For the most part, these should be used on personal workstations or laptop computers. However, there are some exceptional circumstances where it m…

pbsdsh There is a major problem with using GNU parallel directly on the PBSPro cluster: it uses the ssh transport and not momd which means that the PBS does not know about the tasks. This prevents PBSPro from properly monitoring or cleaning up node(s) when a job ends. Especially if that job ends from error or walltime ending.

Material Studio at CHPC This is a package provided by BIOVIA You will need to edit your “hosts.” file (with no extension). The edit is done by copying this hosts file to one of your own dirs such as Documents, edit there, and then copy file back (in the etc\ dir you can't easily edit directly). Do the copy as Administrator (and using Admin elsewhere may help too).
