HPRC user forum/seminar with HPRC Associate Director candidate Tim Kaiser

Dear HPRC Users:

To improve the user services and enhance the computational enablement efforts, the High Performance Research Computing (HPRC) at Texas A&M University has opened an Associate Director of HPRC Enablement position. The Associate Director is responsible for: assisting HPRC Director in developing strategies to build a nationally competitive and recognized center for computational and data-enabled science and engineering, for facilitating the efficient use of HPRC resources for the research of faculty and staff across Texas A&M University, for providing high performance computing training and outreach, and for managing staff who provide technical and knowledge domain consulting to users of HPRC resources, for building and developing strong research collaborations across campus and nationally, for representing HPRC interests on various local, regional and national organizations, for serving as the Campus Champion to provide assistance to local users to use national NSF XSEDE resources.

I am pleased to announce that the third finalist for the position of Associate Director of HPRC Enablement will be on campus August 3-4. Candidate, Dr. Tim Kaiser, is currently the Director of Research and High Performance Computing at the Colorado School of Mines. Dr. Kaiser is a computational scientist who started his career in the defense industry but made the switch to academia at the San Diego Supercomputing Center after receiving his Ph.D. in computer science. He also holds degrees in physics, and electrical engineering. Dr. Kaiser manages Mines’ high performance computing efforts. This includes activities such as: being a mentor, developing documentation, presenting workshops, porting and optimization, teaching, evaluating new technologies, managing the account allocation process, procuring advanced hardware and being an advocate for HPC and HPC users on campus. He is part of the NCAR-Wyoming Supercomputing Center Account Allocations Committee, and a founding member of the Rocky Mountain Advance Computing Consortium. He was a CO-PI on recent NSF Cyber-Infrastructure Engineer position award and recently initiated unique partnerships with national labs for research collaboration. He views his primary job description as: “Help scientist do their science.” When he is not in front of a keyboard you can usually find him on his road bike or in front of a stove, cooking.

An open HPRC user forum/seminar is scheduled for candidate Kaiser on August 4, at 10:45AM-11:45AM, in 3147 ILSB (Interdisciplinary Life Sciences Building). Your participation in the review process for the position of Associate Director of HPRC Enablement is important. Please make your effort to attend this forum/seminar and meet with Dr. Kaiser. He would like to do two presentations with the second being very short. The second is just a bit of fun that can lead to interesting discussions. Here are the titles and abstracts for his talks.

#1 MPI - Parallel IO Workshop Presentation

This talk is from a series of workshop presentations on various topics in high performance computing. This particular talk introduces Message Passing Interface (MPI) parallel IO. We will discuss two applications where MPI parallel IO is useful. The first example is a three dimensional earthquake simulation with very large datasets where we write restart files and/or files for volume visualization. For our second example we discuss writing many 400,000,000 pixel tiff image files, where the calculation of the image content is distributed. For this we briefly discuss the tiff format.

We discuss reasons why people might or, might not want to use MPI parallel IO. We then introduce several of the MPI-IO routines. We will then walk through our examples showing how those calls are use. For our first example we will also discuss the creation of the MPI derived data types used to describe the mapping of our data.

We will discuss a common file system “issue” which prevents some MPI-IO routines from working properly and a work around for that issue. For the tiff example we will discuss the integration of our MPI-IO routines with the Geospatial Data Abstraction Library.

#2 Just Submit a Ticket!

This is a short (5 minute) talk which discusses some motivations of scientists using High Performance Computing systems. In particular, they are trying to do science. They will do what it takes to get their work done fastest, easiest, the best, and often with the least interaction with people. I will present some reasons why scientists are reluctant to submit tickets to help desk systems. This talk often leads to lively discussions.

Thanks a lot and look forward to seeing you at 10:45AM on Thursday.
