(software) How can I use the latest version of R or RStudio??

The current installation on the HBS compute grid for RStudio is v0.99.99 and its companion R version is v3.1.2, the latest that this version of RStudio can fully support. We are aware that these are not recent versions: this is an unfortunate result due to limitations of the operating system (OS) and how software installations are managed on the compute grid. We are currently working with HBS IT find a solution to overcome this limation, which we hope to have remedied by late summer 2017.

In the meantime, if you require a more current version of R within this version of...

(storage) Why do file permissions change when files are copied to research storage home folders and/or project spaces?

File transfer programs, including the Mac Finder and Windows Explorer, try to do  the best job possible matching permission when files are copies over. But since the operating systems typically are different between the source (your computer) and the destination (the storage on the compute grid), the programs attempt to match as best as possible. Of course, they often don't get it right. Please see our HOWTO document on Changing File...

(storage) I'm getting 'permission denied' when trying to view files. What does this mean?

This occurs when either you or a collaborator have not correctly set permissions. Subsequently, the owner of the file will need to change the file's permissions. You can identify the owner (and other permissions details) via the command ls -l MyFile.txt. Please see our HOWTO document on Changing File Permissions. If you need assistance from RCS, please include the output from ls -l...

(compute) I launched an application in NoMachine or the terminal. Why isn't it running?

There are several reasons why an application may not appear to be running:

  • All of the licenses for the application may be in use by others.
  • More commonly, you may have reached the resource limit on your account (# of CPUs or memory limit).
  • If the compute grid is busy, there many not be enough RAM or CPUs on any of the compute nodes to run your application.

Open a terminal session and type bjobs on the command line (...
