R update on Linux machines
Posted: February 3, 2015
We have built a new distribution of R that takes advantage of multithreading when processing numerical arrays and made it the default R to use on CHPC's Linux systems including the clusters. The multithreaded build will run in parallel on a single compute node and standard R linear algebra benchmark achieves 5-10 speedup on kingspeak as compared to the single threaded build. To use multiple nodes, a distributed parallel package such as Rmpi or snow is still necessary.
We have installed external packages that have been built for the older versions but if there is an additional package you need, please, let us know.
For details how to use R at CHPC, see the documentation at

We have updated the default IDL distribution to version 8.4. Please, let us know if you notice any problems with it.
Also, there are some users that use older version that is hardcoded to their environment. If you'd like to use the default (latest) version, either edit your shell init scripts or get in touch with us for help.

We already have over 250 registrations!
So far, the SiPE workshops have reached over 1500 people at 248 institutions, agencies, companies and organizations in 47 US states and territories and 10 other countries:
* 178 academic institutions; * 29 government agencies; * 26 private companies; * 15 not-for-profit organizations.
SiPE is targeted at an audience of not only computer scientists but especially scientists and engineers, including a mixture of undergraduates, graduate students, faculty and staff.
These workshops focus on fundamental issues of High Performance Computing (HPC) as they relate to Computational and Data-enabled Science & Engineering (CDS&E), including:
- overview of HPC;
- the storage hierarchy;
- instruction-level parallelism;
- high performance compilers;
- shared memory parallelism (e.g., OpenMP);
- distributed parallelism (e.g., MPI);
- HPC application types and parallel paradigms;
- multicore optimization;
- high throughput computing;
- accelerator computing (e.g., GPUs);
- scientific and I/O libraries;
- scientific visualization.
The key philosophy of the SiPE workshops is that an HPC-based code should be maintainable, extensible and, most especially, portable across platforms, and should be sufficiently flexible that it can adapt to, and adopt, emerging HPC paradigms.

January 22 at 4pm -- FastX server upgrade
Posted: January 9, 2015
Duration: about an hour
On Thursday January 22 at 4pm we will be upgrading the server side of FastX on the cluster interactive nodes (includes the meteoXX and atmosXX nodes) and the frisco nodes. This process will not take long (about an hour), but there is a chance that existing FastX sessions will not be accessible after the upgrade so we strongly suggest that all FastX sessions are shut down before this time. If this is not possible, at a minimum users should save the results of any processes running within a FastX session.
After the server side upgrade all users will also have to upgrade their FastX clients.
The reason we are doing this upgrade at this time instead of waiting for the next downtime is that we have been notified that we can expect up to a 4-6X speed gain for remote visualization operations using this new server version (version 38) with the latest client version (version 39), based on information provided by the company which produces the FastX product. To see the other fixes and improvements included in the release as well visit the Starnet site .
As always, if you have any questions or concerns with these plans, please contact us.

XSEDE HPC Workshop: Open MP
January 9, 2015
XSEDE along with the Pittsburgh Supercomputing Center and the National Center for Supercomputing Applications at the University of Illinois are pleased to announce a one day OpenMP workshop. This workshop is intended to give C and Fortran programmers a hands-on introduction to OpenMP programming. Attendees will leave with a working knowledge of how to write scalable codes using OpenMP.
CHPC will be one of the satellite sites that will offer this class. There is no cost to attend, but you must register with XSEDE at their site before 3pm on Jan 8, 2015.
The agenda for the Workshop can be found at the registration link.
