Dear JHPCE Community,
Please be advised that the JHPCE cluster will be unavailable starting at 6:00 AM on Monday, January 22nd and will not be available until 5:00 PM on Wednesday, January 24th for power work and network maintenance scheduled to be performed at the Bayview/MARCC site. Please plan your jobs accordingly.
We will also be performing a number of upgrades during this time. Most notably, we will be setting the default version of R on the JHPCE cluster to version 3.4.2. This is a significant change as this version of R will be run within a Conda environment. Conda allows a more consistent, contained environment to be created for applications, and should eliminates issues we have been seeing recently with library incompatibilities with some newer R packages. Thanks to Dr. Kasper Hansen for all of his work in setting up R under the Conda environment.
Please note that you will have to reinstall any locally installed packages that you have under the current R environment. If you wish to install your packages prior to January 22nd, you can run:
module load conda_R
and then run “R”, and reinstall packages for the new R version.
