The Texas Advanced Computing Center (TACC) is pleased to announce that Lonestar 5 (ls5.tacc.utexas.edu) is now in full production. This new system enables researchers across the state access to a 30,000 core, 1.2 PetaFlop Cray XC40 customized by TACC staff to provide a unique environment designed to meet the needs of our diverse community of computational researchers. Like Lonestar 4, Lonestar 5 will also include both GPU-enabled and large memory nodes.

Lonestar 5 has been funded by a collaboration between the University of Texas System, Texas A&M University, Texas Tech University, the Institute for Computational Engineering and Sciences and the Center for Space Research at UT Austin, and TACC.

Accounts of active Lonestar 4 users have automatically been activated on Lonestar 5. PIs with active Lonestar 4 allocation have allocation on Lonestar 5. The amount of Lonestar 5 allocation is .75 of the Lonestar 4 balance on Monday, January 11, 2016. Allocation expiration dates remain the same.

PIs without a current Lonestar 4 allocation should request Lonestar 5 allocation via the TACC User Portal.

https://portal.tacc.utexas.edu

The existing Lonestar 4 will remain in production through Monday, February 15, 2016 to enable users to migrate codes and data to the new system. Lonestar 4 login nodes will remain available through Monday, March 14, 2016 for access to $WORK and $SCRATCH for current Lonestar 4 users to further facilitate migration of their projects to Lonestar 5. Please note the following important dates:

  • January 11, 2016: Lonestar 5 production begins 
  • February 15, 2016: Last day of Lonestar 4 production 
  • March 14, 2016: Last day of access to Lonestar 4 login nodes, $SCRATCH, and $WORK

NOTE: Be sure to read the Lonestar 4 to Lonestar 5 transition guide, available at the following URL:

Stampede Knight's Landing Early Science Program

Request for Applications

The Texas Advanced Computing Center (TACC) at The University of Texas at Austin is seeking applications from research teams wishing to participate in the Early Science Program for the Knight's Landing (KNL) upgrade of Stampede to the second generation of the Intel Xeon Phi processor. 

The Stampede supercomputer at TACC is one of the leading systems in the National Science Foundation (NSF) open cyberinfrastructure, and was the first system to make the original Xeon Phi coprocessor available to the research community at large scale. A portion of the Stampede system will be upgraded to the second generation of Xeon Phi, codenamed Knight's Landing, in the first half of 2016 in preparation for future systems.    

TACC is seeking a set of research teams that would like early access to this technology, and are willing to work closely with TACC in preparing their codes to take full advantage of the next Xeon Phi. TACC staff members will assist successful teams to profile and analyze their application on existing Xeon and Xeon Phi platforms, developing and executing a plan to enhance the code for the KNL processor. Selected teams will receive early access and significant compute time on the KNL nodes on Stampede before they are put into production for general access, as well as a commitment of time from TACC technical staff. Selected teams will be expected to collaborate with TACC on code improvements and benchmarking.

The Stampede Early Science Program will cooperate with similar early adopter programs for Department of Energy Xeon Phi-based systems at Argonne National Lab and the National Energy Research Science Center at Lawrence Berkeley National Labs. Care will be taken in the selection of proposals to avoid duplication of efforts between these programs.    

Projects will begin on a rolling start basis in January 2016. Approximately six to eight teams will be supported. Requests to join the Early Science Program can be made by sending an email to info@tacc.utexas.edu.    A request should include a brief description of the application to be optimized, including current scaling data, and a brief description of the science challenges to be addressed.

For further information, please contact info@tacc.utexas.edu.

Ranch returned to  production on Friday and is now available to users.   We apologize for the lengthy delay in returning this system to service.  During this period, the cache file system was completely rebuilt from a saved image due to the failure of multiple hardware components.  While Ranch can recover thousands of files per second, this recovery unfortunately took much longer than anticipated due to the more than 1.1 billion files that had to be restored.

 

Because the recovery was from a saved image, some user files that were in the process of being transferred to Ranch or that had recently been uploaded to the system prior to the outage may have been lost.  It is recommended that users double check files recently transferred to Ranch to confirm successful completion.   TACC staff are generating a list of files that were not restored, but it will take some additional time to complete the list.  Any users with files that were not recoverable will be notified within the next week.


During the extended recovery process, TACC staff rebalanced the multiple file systems that comprise the Ranch cache to more efficiently distribute the load on the storage servers.   Note: Users that have hard-coded their Ranch home directory path in scripts should be aware that their $HOME file system location may have changed and update their scripts accordingly.

10100 Burnet Rd.
Austin, TX 78758

The Stampede supercomputer at the Texas Advanced Computing Center went into production in January 2013 and is the first system to deploy at scale the Intel Xeon Phi CoProcessor. Stampede provides nearly 10 petaflops of peak performance, and is the flagship system of the US National Science Foundation's XSEDE Cyberinfrastructure. Stampede provides more than 100,000 cores and 2PF of Intel Xeon E5 "Sandy Bridge" processors, and an additional 7+ PF of Intel Xeon Phi CoProcessors.

In this 2 day tutorial, we will introduce the Stampede architecture, and cover how to achieve performance using both the conventional processors as well as the coprocessors.

Topics will include:

-Stampede architecture overview
-The Stampede user environment, including the batch system, compiler environment, application modules, etc.
-MPI and OpenMP parallel programming
-Basic optimization and vector tuning on Stampede for Sandy Bridge and Xeon Phi Coprocessors (MICs)
-Hybrid computing
-Intel Xeon Phi Coprocessor (MIC) overview
-Hands-on exercises with Stampede.

estimate Ranch will return to full production by Friday, October 2.

Updated on Sep 18, 2015 11:58:31 AM

Ranch continues to be unavailable as recovery of the filesystems is taking much longer than anticipated due to additional errors encountered on the primary storage hardware controller.   TACC Staff continue to work with the vendor to repair the hardware and restore user access, however, based on current estimates, it will take another week to recover the filesystems due to the large quantity of files and data stored on the system.   We apologize for any inconvenience this has caused and we are working as fast as possible to restore user access to Ranch.

Updated on Sep 15, 2015 10:20:35 AM

The system administrators, along with the vendors, have continued work on Ranch and expect Ranch to return in service sometime on Thursday, 9/17/15.
