January Maintenance under way

Posted by on Tuesday, 14 January, 2014

The January maintenance period has begun.
All clusters will be inaccessible until maintenance is over.

Power loss in Rich Datacenter

Posted by on Thursday, 19 December, 2013

UPDATE: All clusters are up and ready for service.

At this time, all PACE-managed clusters are believed to be working.
You should be able to login to your clusters and submit and run jobs.

Any jobs that were running before the power outage have failed, so please resubmit them.

Please let us know immediately if anything is still broken.

PACE Team

What happened

At around 0810 Thursday morning, Rich lost its N6 feed, half of the feed powering the Rich building and the Rich chiller plant. This also caused multiple failures in the high voltage vault in the Rich back alley, so Rich also lost its other feed, N5. However, the N5 feed was still up in the chiller plant. Though the chillers still had power, as a precaution operators transferred cooling over to the campus loop. Rich office space was without power, but the machine rooms failed over to the generator and UPSes.

PACE systems were powered down gracefully to prevent a hard-shutdown that would make recovery more difficult.

Original Post

This morning (December 19), the Rich datacenter suffered a power loss.
We had to perform an emergency shutdown of all nodes.

As we receive new information we will update this blog and the pace-availability email list.

Login Node Storage Server Problems

Posted by on Monday, 1 July, 2013

Last night (2013/06/30), one of the storage servers that is responsible for many of the cluster login nodes encountered some major problems.
These issues are preventing the login nodes from allowing any user to login or use the server.
Following is a list of the affected login nodes:
cee
chemprot
cns
cygnus-6
force-6
force
math
mokeys
optimus
testflight-6

We are aware of the problem and we are working as quickly as possible to fix this.
Please let us know of any problems you are having that may be related to this.
We will keep you posted about our progress.

PACE Sponsors High Performance Computing Townhall!

Posted by on Friday, 5 April, 2013

PACE sponsoring HPC Townhall

What could you do with over 25,000 computer cores? Join faculty and students at the April 30 High Performance Computing Town Hall to find out. The event will be held in the MaRC auditorium and is sponsored by PACE, Georgia Tech’s Advanced Computing Environment program.

When: April 30, 3-5pm
Where: MaRC Auditorium (Map to location)

Overview

PACE provides researchers with a robust computing platform that enables faculty and students to carry out research initiatives without the burden of maintaining infrastructure, software, and dedicated technicians. The program’s services are managed by OIT’s Academic & Research Technologies department and include physical hosting, system management infrastructure, high-speed scratch storage, home directory space, commodity networking, and common HPC software such as RedHat Enterprise Linux, VASP, LAMMPS, BLAST, Matlab, Mathematica, and Ansys Fluent. Various compilers, math libraries and other middleware is available for those who author their own codes.  All of these resources are designed and offered with the specific intention of combining intellect with efficiency, in order to advance the research presence here at Tech to the peak of its abilities.

There are many ways to participate with PACE.  With a common infrastructure, we support clusters dedicated to individual PIs or research groups, clusters that are shared amongst participants and our FoRCE Research Computing Environment (aka “The FoRCE”).  The FoRCE is available to all campus users via a merit-based proposal mechanism.

The April 30 HPC Town Hall is open to members of the Tech research community and will feature presentations on the successes and challenges that PACE is currently experiencing, followed by a panel discussion and Q&A.

For more information on the PACE program, visit the official website at www.pace.gatech.edu, and also the program’s blog at blog.pace.gatech.edu.

Agenda (To Be Finalized Soon)

  • Message from Georgia Tech’s CTO Ron Hutchins
  • Message from PACE’s director Neil Bright
  • Lightning Talks By Faculty
  • Discussion around technologies and capabilities currently under investigation by PACE
  • Panel Discussion regarding future directions for PACE
  • Question and Answer Session
