TACC Training – Parallel Computing on Stampede

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 new 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 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

Stampede Two-Phase Transition to Intel 15

Posted by Jesse Snead on Mar 17, 2015 2:04:37 PM

During scheduled Stampede maintenance on Tuesday, March 31, 2015 and Tuesday, April 28, 2015, TACC will conduct a two-phase transition to a software stack based on the Intel 15 compiler.

During scheduled Stampede maintenance on Tuesday, March 31, 2015 and Tuesday, April 28, 2015, TACC will conduct a two-phase transition to a software stack based on the Intel 15 compiler.


On Tuesday, March 31, 2015, we plan to remove from Stampede the Intel 13.0.1.117 and Intel 13.1.1.163 compilers. A month later, on Tuesday, April 28, 2015, we plan to install the Intel 15 compiler and a large stack of compatible production software. Intel MPI 5 and gcc 4.9.1 will also become available for the first time.

When the two-phase transition is complete, the Stampede software stack will include the following Intel compilers:
intel/13.0.079  	# original production compiler
intel/13.0.2.146	# *** DEFAULT ***
intel/14.0.1.106	# limited software stack
intel/15.0.1    	# available on or about April 28, 2015
Intel 13.0.2.146 and mvapich2/1.9a2 will remain the default compiler and MPI library for the near-term future. 

The planned upgrades includes a number of changes of particular interest to those who use Python, PETSc, or C++11/C++14. See https://portal.tacc.utexas.edu/user-guides/stampede/intel15 for additional information. The web link also includes a list of new packages built with or supporting either the Intel 15 or gcc 4.9 compiler.

Stampede Scratch File System Outage

Updated on Jan 22, 2015 10:35:29 AM

TACC staff has completed recovery operations on the section of /scratch that went offline this past Sunday. We have recovered more than 99.9% of the files and have restored all recovered files as of 8:00AM on 1/22/2015. We encourage users to check the status of their files in $SCRATCH as few hundred files could have been affected by this filesystem problem.
If you receive the message "Cannot allocate memory" when trying to access a file, this means that a portion of the file was on the offline portion of /scratch and could not be recovered. You should remove any such file using "rm -f filename".
To generate a file containing information on all of your files that were offline, execute the command:
lfs getstripe -r -O scratch-OST0094_UUID $SCRATCH | sed '/^$/d' > ost_info.out
To extract the list of files that might have been affected, execute:
grep scratch ost_info.out
 
and list those files with ls -l to see if any generate a “Cannot allocate memory” message.  Users may also consult this page for instructions from a previous outage, but replace OST0010 with OST0094: https://portal.tacc.utexas.edu/user-news/stampede-scratch-file-system-outage
