Stampede 2 Update: Stampede 1’s Production KNL Sub-System Moving to Stampede 2

The Stampede 2 deployment continues to go well: we expect to begin Phase 1 production service during the week of June 7 with a full complement of 4,200 Intel Knights Landing (KNL) compute nodes. Later this summer we’ll begin Phase 2 deployment of an additional 1,736 nodes featuring an upcoming...

The Stampede 2 deployment continues to go well: we expect to begin Phase 1 production service during the week of June 7 with a full complement of 4,200 Intel Knights Landing (KNL) compute nodes. Later this summer we’ll begin Phase 2 deployment of an additional 1,736 nodes featuring an upcoming Intel processor. We will continue to downsize Stampede 1 as this transition proceeds, but Stampede 1 will remain available until Fall 2017 when Stampede 2 enters full production.

The next major step focuses on the 508 KNL nodes (https://portal.tacc.utexas.edu/user-guides/stampede#stampede-knl-cluster) that are currently in production as a sub-system of the existing Stampede cluster. On or about Wednesday, 17 May 2017 we will stop accepting new jobs on the KNL sub-system. We will do our best to allow pending jobs to run to completion before we permanently retire the login-knl1 login node. This will have no effect on the availability of your files: the Sandy Bridge and KNL sides of Stampede 1 share the same home, work, and scratch file systems.

Please watch TACC User News (https://portal.tacc.utexas.edu/user-news) for additional information over the next few weeks. For now, note that TACC will have no KNLs in production service for a 3-4 week period beginning in mid-May. The temporary absence of 508 KNL nodes will likely put additional pressure on the Sandy Bridge queues. We especially appreciate your patience with queue wait times as we continue the process of installing Stampede 2.

Please submit any questions you may have through the TACC Consulting System or feedback form.

The Computational Techniques for Life Sciences Institute is a five day immersive training event for researchers in the life sciences. Participants will learn the basic skills necessary to develop and execute life sciences workflows on large-scale systems, run parallel analyses, use Bash and Python to chain common life sciences applications together to form more complex workflows, and analyze result data in order to gain useful insights.

TACC's Life Sciences Computing team members will also spend time one-on-one with participants discussing how to accelerate their existing research or how to start a new project by beginning with the best computational practices.

On April 28th, 2017; TACC will be offering a morning introductory course and an afternoon performance optimization course on OpenMP.

The morning course will introduce participants to the OpenMP threading model, and describe the basic constructs necessary to parallelize loops on manycore architectures. Topics covered will include understanding the fork/join threading model, using OpenMP pragmas, and loop parallelization.

The afternoon course will provide an introduction to OpenMP optimization techniques for manycore and vectorized architectures. Topics covered will include using OpenMP’s SIMD directives, configuring OpenMP thread affinity, and changing OpenMP thread scheduling behavior.

You are welcome to register for either or both courses. Both of the courses are available to in-person and webcast participants. Local participants are strongly encouraged to attend in person.
