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,

Compute Grid Tip of the Month - May 2017

Parallel/Multicore Processing

Using multiple cores (CPUs) to analyze data is an efficient way to get more work done in less time. But this is true only under certain circumstances. By default, R, Python, and MATLAB can only use one core even on a multicore (multiCPU) machine, unless you specifically program them to use more. Stata, on the other hand, has been parallelized, so many of its functions can use more than one core, but only to a maximum of 75% efficiency overall. To get the most efficiency, its best to run your 'do' files in batch; if using the interactive GUI, Stata spends

Grid Maintenance - May 2017

April 26, 2017

This is a reminder that the monthly Grid maintenance is scheduled for Monday, May 1st, from 8am until 12pm.

How will this affect you?

  • All sessions to the login nodes will be terminated (including terminal and NoMachine sessions)
  • All interactive sessions will be terminated
  • You will not be able to login to the grid
  • You will not be able to use NoMachine
  • Modules installed under Python v2.6 that include compiled code may need to be reinstalled under the

Turn those icons off!

If you are using project spaces and home folders on the research storage (part of the HBS compute grid), it is likely that you will need to access these while not on the HBS campus. If you are mapping drives or mounting shared folders, the default settings in both Windows and Mac OS may be working against you, as the OS will try to present the files to you with an icon of the contents. This takes much more time to display in Finder or Explorer windows that simple generic file icons, especially over the VPN. Read more about Compute Grid Tip of the Month - April 2017

Choose your resources efficiently

Using the HBS Compute Grid is a great opportunity to scale your research beyond what you can do on a desktop or laptop. But, as a shared resource, we all have a responsibility to use the resources appropriately. The biggest impediment we face is Grid users over-requesting RAM and CPUs: once requested and allocated, these are not returned to the general pool until your job has finished or you have quit your program in the interactive session (the programs from the Applications drop-down menu in NoMachine). So, if you ask for more resources than your job or program needs, those “extra” resources are, in effect, wasted/unavailable to be used by other users. Please help other users out by choosing your resources efficiently when running jobs and program (“Take What You Need, but Need What You Take”).
