Stampede2 will be unavailable from 8 a.m. to 7:30 p.m. (CT) on Tuesday, 17 July 2018. System maintenance will be performed during this time.

 

If you submit a job before the maintenance, and the time you request exceeds the time remaining until the maintenance begins, your job will run when the maintenance is over. The squeue command will report "ReqNodeNotAvailable" ("Required Node Not Available"). The showq utility will list the job as "BLOCKED" and report its status as "WaitNod" ("Waiting for Nodes"). Note that the hours leading up to the maintenance are an excellent time to submit shorter, smaller jobs that can complete before the maintenance begins: as the queues drain there will be many nodes available, and your wait time may be short.

In parallel codes MPI (Message Passing Interface) is the predominant method for communicating data between the nodes of a compute cluster. It is widely used and performs well on a large variety of hardware platforms, and therefore a basic understanding of MPI programming is beneficial to anybody working in the field of high-performance computing (HPC). In this beginner-level training session, we will provide an overview of the basic concepts of MPI. We will introduce the trainees to the Interactive Parallelization Tool (IPT) that is designed for parallelizing serial C/C++ programs semi-automatically. The participants in the training session will be introduced to MPI and will learn to use IPT for parallelizing their C/C++ applications. 

Prerequisites: Experience working in a Linux environment, and familiarity with C/C++/Fortran or other programming language.

To better serve the Stampede2 user community, we’ve made several important changes to the queues:

  • A new “long” queue allows you to run KNL jobs for up to 96 hrs.
  • We’ve slightly relaxed the development queue limits.
  • There are now fewer nodes in the flat-quadrant queue; we’ve made a corresponding change to the associated queue limits.

Wrangler Maintenance 13 March 2018

Wrangler will be taking an emergency maintenance on Tuesday the 13th to recover from a hardware failure that requires filesystems to be unmounted to resolve. We apologize for the short notice.

Updated on Mar 27, 2018 4:41:16 PM

After extensive hardware issues and then filesystem recovery attempts Wrangler now has /gpfs/flash available cluster-wide. We've ended up with a number of files in the lost+found location after the fsck repair programs finally completed cleanly. /gpfs/flash is the scratch filesystem in the Wrangler cluster so we expect files to be replicated elsewhere but if there were any files that are of very high value that are missing there's a chance that they can be restored. Please submit a consulting ticket and the Wrangler admins will determine if they can be restored. Please note that the lost+found recovery location is the combination of all files in no particular order or structure and requires substantial sorting to track down individual entries.

Updated on Mar 13, 2018 5:03:14 PM

Wrangler will be returning to production shortly however we are not able to restore the gpfs/flash filesystem at this point. This is a hardware related issue that is currently being worked on. Please note that jobs that we can identify as definitely using gpfs/flash have been suspended and will be automatically resumed when the filesystem is available.

Today's filesystem work is taking longer than expected and the Stampede2 maintenance will be extended.

Original Posting

Stampede2 will be unavailable from 8 a.m. to 7:30 p.m. (CT) on Tuesday, 20 March 2018. System maintenance will be performed during this time.

 

If you submit a job before the maintenance, and the time you request exceeds the time remaining until the maintenance begins, your job will run when the maintenance is over. The squeue command will report "ReqNodeNotAvailable" ("Required Node Not Available"). The showq utility will list the job as "BLOCKED" and report its status as "WaitNod" ("Waiting for Nodes"). Note that the hours leading up to the maintenance are an excellent time to submit shorter, smaller jobs that can complete before the maintenance begins: as the queues drain there will be many nodes available, and your wait time may be short.

Corral has had an unexpected disk error that caused the file system to unmount causing a brief interruption shortly before noon (local time). The file system is back up now, but users can report any errors they encounter to the TACC User Portal at the URL below. https://portal.tacc.utexas.edu/...
