High Performance Computing on Frontera Training 7, 14 & 21 October 2021

Registration is now open for TACC's fall HPC training on Frontera. High Performance Computing on Frontera is a three-day training series offered on consecutive Thursdays starting October 7. Registrants for this event are encouraged to attend all three days.

During the first day (October 7), we focus on parallel programming with MPI. We provide an introduction to MPI in the morning and delve into advanced topics in the afternoon. We also discuss hybrid computing and the interplay between OpenMP and MPI with a single code.

On the second day (October 14), the focus shifts to OpenMP, again covering an introduction and some intermediate topics.

On the last day (October 21), we intend to cover Parallel I/O, the use of containers on TACC large-scale systems, and the use of Remora.

Please note this reminder regarding the /work changes scheduled for 29 June and to please recheck the https://portal.tacc.utexas.edu/tutorials/stockyard-work-migration. Currently the "/work" file system is mounted as "read-only" on both the login and compute nodes of all TACC resources. On June 29th TACC will initiate the following switch over: "/work" will transform into a symbolic link pointing to the new /work2 file system. The "/work" file system will then be re-mounted as "/work_old only on each resource's login nodes (only) to allow for last minute file transfers.

If any jobs still utilize any files on /work while running they will be impacted by these changes.
