Using the clusters
Below are a variety of notes for getting the most out of the parallel systems and research compute assets (Pascal and the Mathematicians).
Connecting & Running Jobs
- For Windows machines, MobaXterm has proven to be an effective free client; Putty is another free option.
- The screen and TMUX utilities are installed to facilitate running GUI-powered and other jobs requiring stable SSH connections. MEH 138 has console access for euler/noether/fermat/mandelbrot; this is another way to leave something running easily.
The mathematicians and penguins are equipped with computational environments (note – loads vary by machine):
- /opt/maple2019/bin/xmaple (GUI)
- /opt/maple2019/bin/maple (Command line)
- Matlab (see: toolboxes list) – /usr/local/MATLAB/R2018a/bin/matlab and/or /usr/local/MATLAB/R2020a/bin/matlab
- NetLogo – /usr/local/NetLogo_6.1.0/NetLogo
- The NVIDIA CUDA tools (see /usr/local/CUDA)
- R Studio
- on mandelbrot use: QMLSCENE_DEVICE=softwarecontext rstudio
- on all other systems use: rstudio
- Ubuntu Linux is the usual OS (currently v. 18 or 20 LTS); exceptions include the BCCD, which runs LittleFe.
- The Unix/Linux OS family allows the “:” character in filenames. Windows does not… (bulk rename utilities are available, however)
- Spaces in filenames on Unix/Linux are good to avoid. (Permitted, but not recommended…!
