Stampede2 will be unavailable from 8 a.m. to 7:30 p.m. (CT) on Tuesday, 20 February 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.

The Stampede2 maintenance is complete and the system is back in production. During the maintenance we upgraded the login nodes. This should have little to no adverse impact, but you may need to take minor actions to account for the new login nodes: e.g. reschedule cron jobs or update known hosts on your client.

Stampede2 maintenance has been extended.  We will provide further updates as they become available.

As a reminder, Stampede2 will undergo scheduled system maintenance on Tuesday, 23 Jan 2018 between 8:00AM and 7:30PM CST. This is the maintenance originally scheduled for 16 Jan 2018 that we delayed due to inclement weather. The system will be unavailable during this window.

 

Planned activities include upgrading the login nodes. This should have little to no adverse impact, but after the maintenance you may need to take minor actions to account for the new login nodes: e.g. rescheduling cron jobs or updating known hosts on your client.

 

If you submit a job before the maintenance, and your job cannot finish before 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").

OpenMP is one of the most popular paradigms to exploit the now ubiquitous manycore and multi-core processors. In this beginner-level training session, we will provide an overview of the basic concepts of OpenMP. 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 OpenMP 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 any other programming language.

We are offering the training to both in-person and webcast participants. Local participants are strongly encouraged to attend in person.

To attend the training in person, please contact me via email at jasona@tacc.utexas.edu.
