Research Grid - Summer Reminder

June 2, 2017

Summer has arrived and many now have the opportunity to relax. But at the same time, for many this is a time to focus on research projects that have been on hold. For that reason, we ask you to be mindful of appropriate use of the compute grid resources:

  • Use an appropriate amount of RAM for your work. A good rule of thumb is to ask for memory that is about 10X as large as your file size + wiggle room. So if your dataset is 500 MB, then use a 5 GB memory partition first before asking for something larger.
  • Don't let compute sit idle, and don’t keep programs running for more than 2 to 3 days (7 days max). RAM and CPU reserved for you cannot be used by anyone else. And our 250-core compute grid needs to be shared by 180+ faculty and 100+ graduate students, not to mention the legions of RAs that assist us.
  • Multiple CPUs can be used interactively in Stata in short bursts, and in R, Python, and MATLAB only if programmed to do so. Don't ask for more than 1 core unless you know you can use it.

Remember, "Take What You Need, but Need What You Take".
