On Tuesday, April 21, from 9am CDT to approximately 6pm, Stampede will be running some full-system jobs. As the scheduler begins to drain the system ahead of the time reserved for these runs, the reported system load will be lower than normal. 


Short jobs will receive higher priority if they are able to complete in the time remaining before the full-system runs; longer jobs will remain in the queue until the full-system jobs are complete. The reservation does not affect the largemem queue or access to the login nodes.

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

Posted by Garland Whiteside on Jan 18, 2015 7:46:45 AM

One of the storage targets on the /scratch filesystem for Stampede encountered an error at 5:45AM and had to be taken offline to be checked.   Users trying to access files on the scratch-OST0094 will encounter an error similar to "Cannot send after transport endpoint shutdown".    TACC Staff are...

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

Updated on Dec 24, 2014 6:28:50 PM

TACC staff has completed recovery operations on scratch-OST0049, the Object Storage Target (OST) in the /scratch file system that has been offline since last Friday. We have recovered more than 99.9% of the files that were on this OST, and have restored all recovered files as of noon on 12/24/2014. We encourage users to check the status of their files in $SCRATCH as several hundred files could have been impacted by this filesystem problem..

Managers of community, portal, or gateway accounts may find that they have issues with ownership and permissions on some of their files in $SCRATCH.

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 OST 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 located on the offline OST, execute the command:

lfs getstripe -r -O scratch-OST0049_UUID $SCRATCH | sed '/^$/d' > ost_info.out

To extract from this file a list of affected files, execute:

Corral Group Quotas 6 January 2015

Posted by Jesse Snead on Dec 9, 2014 3:10:23 PM

On Tuesday, January 6, 2015 default project group quotas of 1TB will go into effect for all data on Corral. Although quotas are currently assigned for all allocated projects on Corral, in the past, no quotas have been assigned for un-allocated projects and no usage reporting is done for project...

On Tuesday, January 6, 2015 default project group quotas of 1TB will go into effect for all data on Corral. Although quotas are currently assigned for all allocated projects on Corral, in the past, no quotas have been assigned for un-allocated projects and no usage reporting is done for project groups without Corral allocations. This means that, under certain circumstances, users may have significant amounts of data on Corral not currently subject to reporting and quota mechanisms. For users whose data is all owned by the correct project group, this change will have no effect. However, users with significant amounts of data stored under a project group without a Corral allocation may experience problems after the quota implementation. 


Users can check project group IDs by logging into the TACC user portal ( https://portal.tacc.utexas.edu/projects-and-allocations ), clicking on “Projects and Allocations” under the Allocations tab, then clicking on any project detail button. At the top of the resulting page will be a line labeled “Unix Group”. The value listed there should match the group ID you see when you list the contents of your Corral directories with “ls -l” or in the file details of any graphical file transfer tool such as Cyberduck. You may also check your Corral allocation usage in the TACC user portal and see if the value there matches your expectations based on the amount of data you have stored.

If you have significant amounts of data with an incorrect project group and need help correcting this or if you have any questions regarding this announcement, please contact TACC support via the TACC User Portal.

Due to a hardware error on an OSS server, Stockyard $WORK file system suffered a partial (affecting processes accessing particular subset of OST’s) interruption in service between 8:12PM - 8:59PM.  Due to a potentially severe file system corruption on a single OST, the target (gsfs-OST00cd) is currently off-line and will not be back in service until repair is done.

This could take days and we may disable the target on clients to prevent hang.
