New and Updated Software: Portland Group Compiler and ANSYS

Posted by on Tuesday, 29 January, 2013

Two new sets of software have been installed on PACE-managed systems – PGI 12.10 and ANSYS 14.5 service pack 1.

PGI 12.10

The Portland Group, Inc. (a.k.a. PGI) makes software compilers and tools for parallel computing. The Portland Group offers optimizing parallel FORTRAN 2003, C99 and C++ compilers and tools for workstations, servers and clusters running Linux, MacOS or Windows operating systems based on the following microprocessors:

This version of the compiler supports the OpenACC GPU programming directives.
More information can be found at The Portland Group website.
Information about using this compiler with the OpenACC directives can be found at PGI Insider and OpenACC.

Usage Example

$ module load pgi/12.10
$ pgfortran example.f90
$ ./a.out
Hello World

ANSYS 14.5 Service Pack 1

ANSYS develops, markets and supports engineering simulation software used to foresee how product designs will behave and how manufacturing processes will operate in real-world environments.

Usage Example

$ module load ansys/14.5
$ ansys145

Panasas problems, impacting all PACE clusters

Posted by on Friday, 18 January, 2013

The Panasas storage server started responding slowly approximately an hour ago. We are using this server to host all of the software stack, and also for the “scratch” directory in your home folders. 

No jobs have been killed, but you will notice significant degradation in the performance. Starting new jobs/commands will be also slow, although they should run.

We are actively working with the vendor to resolve these issues and will keep you updated via this blog and the “pace-availability” email list.

Thank you for your patience.

Collapsing nvidiagpu and nvidia-gpu queues

Posted by on Wednesday, 16 January, 2013

PACE has several nodes with NVidia GPUs installed.
There are currently two queues (nvidiagpu and nvidia-gpu) that have GPU nodes assigned to them.
It is confusing to have two queues with the same purpose and slightly different names, so PACE will be collapsing both queues into the “nvidia-gpu” queue.
That means that the nvidiagpu queue will disappear, and the nvidia-gpu queue will have all of the resources contained by both queues.

Please send any questions or concerns to pace-support@oit.gatech.edu

January 2013 quarterly maintenance is complete

Posted by on Wednesday, 16 January, 2013

Greetings!

We have completed our quarterly maintenance activities.  Head nodes are online again and available for use, queued up jobs have been released, and the scheduler is awaiting new submissions.

Our RedHat 6 clusters have received system software updates.  Please keep an eye on your jobs to verify everything is operating correctly.

Our Panasas scratch storage has received another round of updates.  Preliminary testing indicates that we should have a resolution to our crashes, but the quota system is known to be broken.  As advised by Panasas, we have disabled quotas on scratch.  Please do your best to stay below the 20TB threshold.  We will be monitoring usage and know where you live.  :)

We have a new license server providing checkouts of the Portland Group and Intel compilers, Matlab DCS, the Allinea DDT debugger and Lumerical.  Please let us know if you have problems accessing this software.  The old server is still running and we will be monitoring it for a short while for extraneous activity.

More nodes from Joe and the FoRCE have been converted from RHEL5 to RHEL6.  If you are still using the RHEL5 side of the world, please prioritize a transition to RHEL6.  We stand ready to assist you with this transition.

Finally, our new configuration system has been deployed in prototype mode.  We will use this to gather operational information and other data that will facilitate a full transition to this system in a future maintenance day.

As usual, please let us know (via email to pace-support@oit.gatech.edu) if you encounter any issues.

Happy Computing!

Symposium: Integrating Computational Science into your Undergraduate Curriculum

Posted by on Monday, 14 January, 2013

Clemson University (Clemson, SC) is hosting a symposium on February 11, 12, and 13.
The topic is “Integrating Computational Science into your Undergraduate Curriculum”
The workshop, symposium and training are open at no charge to all interested faculty and students who register to attend.
Financial assistance for primarily undergraduate faculty is available to cover travel costs.

See the Symposium website for the agenda and registration information.

Datacenter modifications

Posted by on Tuesday, 8 January, 2013

Tomorrow morning (January 9) at 8:30am, facilities management will be performing some work on the power distribution systems in the Rich datacenter.  None of this work is being performed on anything that power PACE systems; there should be zero impact on any job or computer that PACE manages.  However, due to the nature of sharing space in the datacenter; in the event of a major problem, PACE systems may be affected.

Once again, there should be zero impact on PACE systems; no jobs or computers should be affected.

Please let us know (via email to pace-support@oit.gatech.edu) if you have any questions or concerns.
