High Performance Computing Updates

In early April, RCCI completed the High Performance Computing (HPC) Storage project by migrating all user data to newer hardware. The transition to the latest generation of hardware provides better hard drive failure protection, a significant amount of SSD caching and higher transactional processing power. In addition to the storage migration, RCCI applied OS updates to the login and management nodes and migrated compute nodes from RedCat to Rider.

RCCI has added 36 compute nodes (864 processors in the form compt[253-288]. The next HPC project will be adding additional compute and network capacity to the Rider cluster. This should occur during the next maintenance period this Summer.

**Please note that RedCat cluster will cease operation on Friday, June 1. All users should migrate to the Rider cluster immediately.

RCCI Office Hours

If you are new to HPC or any of the other research computing services RCCI provides, please drop by Crawford Hall. RCCI's office hours are every Wednesday from 2:00 pm - 4:00 pm in room 559 or 561. If you are not available during office hours, please contact RCCI at to schedule an alternative date and time.

Cyberinfrastructure Day 2018 Highlights


RCCI would like to thank the campus research community for their participation in the CyberInfrastructure (CI) Day 2018. Invited speakers, Professors Timothy Beal, Robert Kirsch and Jill Barnholtz-Sloan, presented extended accounts of their work. Contributed talks and posters were presented throughout the day, providing engaging introductions to the meaningful work underway in the campus community. Topics ranged over molecular interactions, digital analysis of classic text translation, photovoltaic system durability testing, restoring function in the case of arm paralysis and brain tumor discoveries.

A recap of talks with titles is provided below, as well as posters presented during the day.

RCCI looks forward to CI Day 2019 next spring semester and welcome suggestions and discussion to enrich the event for the campus and extended community.

DataFest 2018 Highlights

The American Statistical Association (ASA) DataFest is a national celebration of data in which teams of undergraduates work around the clock to find and share meaning in a large, rich and complex data set.

Organized at CWRU by Professor Jenny Brynjarsdottir from the Department of Mathematics, Applied Mathematics and Statistics, undergraduates work on solving problems while being assisted by VIP consultants from academia and industry. To help assist data teams, RCCI provided access to High Performance Computing (HPC) to all participants of the DataFest. Moreover, two members of the RCCI group, Dr. Daniel Balagué and Dr. Emily Dragowsky, participated as VIP consultants.

One of the participant groups, “Back for the seconds” took advantage of the resources provided by RCCI for the DataFest. The group used the HPC cluster for running R for statistical computing. The group faced two challenges when trying to use the cluster. The first challenge was to set up their environment for running the scripts that they were developing on their local machines - the users had to install a few R packages. The second challenge was to create batch jobs so that their scripts could run in the HPC cluster through the scheduler. Our RCCI consultants were able to help students installing required packages in their HPC accounts and assisted the group in allocating proper resources on the cluster for running their jobs.

Spring 2018 Workshops Offerings
Please visit RCCI's website for more information about our workshop offerings and how to sign up to attend.

XSEDE Off-Campus Training

There are two summer training opportunities associated with the XSEDE (eXtreme Science and Engineering Discovery Environment) National Super-computing organization.

Session One: SDSC Summer Institute 2018: High Performance Computing and Data Science

Location: San Diego Supercomputer Center (SDSC), UC San Diego

Date: August 6 – 10, 2018

Applications accepted through May 4, 2018.

The SDSC Summer Institute is a week-long workshop providing attendees a broad spectrum of introductory-to-intermediate topics in High Performance Computing and Data Science to accelerate their learning process through highly interactive classes with hands-on tutorials on the Comet supercomputer.  The program is aimed at researchers in academia and industry, especially in domains not traditionally engaged in super-computing, who have problems that cannot typically be solved using local computing resources. Visit the for program details, application and scholarship information.

Session Two: XSEDE HPC Summer Bootcamp 2018

Location: Pittsburgh Supercomputing Center (PSC), UC San Diego

Date: June 4 - 7, 2018  Carnegie Mellon University and University of Pittsburgh

This 4 day event will include MPI, OpenMP, OpenACC and accelerators. It concludes with a special hybrid exercise contest that will challenge the students to apply their skills over the following 3 weeks and be awarded the Fifth Annual XSEDE Summer Boot Camp Championship Trophy. To learn more and to register, please use the following link:

XSEDE provides access to large-scale computing facilities at universities such as UC San Diego, University of Texas, University of Illinois and University of Pittsburgh, through their associated national super-computing facilities. Access to resources is proposal-based and the resources available without financial cost.

Links to some of the facilities are below, including the XSEDE site.
