High Performance Computing

Workshop: Using the Arkansas High Performance Computing Center's HPC resources

The AHPCC New User Workshop on November 6th was extremely well attended showing us that there is a real need for more events of this type. A total of 23 new users from various domains and multiple institutions showed up to get a leg up on using the HPC resources. The slides from the workshop are available here.

New User Workshop 2013

We really appreciate the support and dedication of our users and look forward to new and improved offerings in the way of training and education in 2014.

Chemistry HPC Users Publish in PNAS

In July 2013, Yaping Li, Jicun Li, and Feng Wang of UA Chemistry and Biochemistry published their research "Liquid–liquid transition in supercooled water suggested by microsecond simulations" in the prestigious journal Proceedings of the National Academy of Sciences.  Calculations supporting the research used the molecular dynamics package Gromacs on the Razor cluster.   To learn more, read the Newswire article.

Two Student HPC Users Win Awards

Tobias Bothwell has been named a 2013 Goldwater Scholar, a national award given to top students in the fields of mathematics, science and engineering. Raymond Walter has won a National Science Foundation Graduate Research Fellowship for the upcoming academic year.

Bothwell, a junior double majoring in physics and mathematics, will receive a scholarship of up to $7,500 from the Barry Goldwater Scholarship Foundation. His research mentor is physics professor Salvador Barraza-Lopez, and his focus is quantum theory. For more information about the Goldwater, read the Newswire article.

Walter, majoring in physics, mathematics and economics, will receive a $30,000 fellowship, renewable for up to three years. The graduate fellowship program is one of the National Science Foundation’s oldest and most highly competitive, with roots in the foundation’s original 1950 charter and offering support for graduate study in all scientific disciplines.

New HPC Course This Fall

AHPCC's Pawel Wolinski is teaching a special topics course in the Fall 2013 semester! 

CSCE 4013 Introduction to Cluster Computing - Dr. Pawel Wolinski

High Performance Cluster Computing is required to solve problems which are too large, in terms of memory or run time, for a single workstation. A common approach to these problems is to combine the resources of multiple computers (clusters of nodes) to collectively find the solution. As the problem sizes grow, HPCC is quickly widening its applicability and currently includes fields such as: chemistry, physics, mathematics, computer, mechanical, industrial and electrical engineering, bio-informatics, finance, logistics, and others.

At the completion of the course students will be able to use HPCC resources, available both at the UofA campus and at other computing centres, to run large scale calculations in their respective fields of study. Skills learned will include: basic Linux commands, bash shell, simple scripting, environmental variables (modules), queueing environment, job input preparation, file compression, networking tools, data mining and processing tools, building open source packages, basic mpi programming, multi-node parallel execution, data visualization.

Research Experience for Undergraduates at Clemson University

2013 Summer Program in Data Intensive Computing
Clemson University
Clemson, South Carolina
June 3 - July 26 2013
Contact: Brian Dean (bcdean@clemson.edu)

Application review will begin in late March.
Applications will be accepted until all positions are filled.

Undergraduate computing, engineering, and science students, come join Clemson University's NSF-funded REU summer program on data-intensive computing. Students will be matched with a faculty mentor at the beginning of the summer program, and each student will participate in a focused research project.

Faculty mentors participating in the program have a broad range of interests in data-intensive computing, from "Big Data" analytics and architectures to biomedical informatics to computational ecology to reliable software engineering, and much more. The program also includes extensive training in tools and technology used in data-intensive computing research, as well as enrichment lectures, excursions, and social events.

Intel Case Study of Razor Upgrade

AHPCC participated in Intel's Customer Reference program, where they used our Razor upgrade as a case study:

In designing and deploying the new environment, the AHPCC team was reminded of the importance of optimizing applications to capitalize on processor advancements. “Organizations need to research their code base and recompile applications,” says Jeff Pummill, manager for cyberinfrastructure enablement at the AHPCC. “That work is vital in fully exploiting the latest processor architectures.”

“According to our testing, the new nodes deliver from one- and-a-half to two times the performance of the previous- generation nodes. We can help researchers address larger research questions and produce results faster than before,” said Rick McMullen, director.

The final case study can be found offsite.
