  1. High Performance Computing University of Alabama in Huntsville Alabama A&M University Alabama State University Athens State University Auburn University -Montgomery Bevill State College Jacksonville State University Troy University Tuskegee University University of West Alabama University of Montevallo U.S. Air Force U.S. Army NASA Intel Corporation Operon Biotechnologies Time Domain University of Alabama at Birmingham University of Alabama University of South Alabama Auburn University

  2. Alabama Supercomputer Applications • Materials Science • Computational Fluid Dynamics • Computer Science • Medical • Social Science • Education • Electromagnetics • Computational Chemistry • Structural Dynamics • Physics • Earth Science

  3. Compilers and Programming • Compilers • GNU C/C++ Fortran 77 (All) • Intel C/C++ Fortran 77/90/95 (All) • Portland Group Fortran 77/90/HP (XD1 Only) • Pathscale Fortran 77/90 (XD1 only) • Parallel Programming • OpenMP • MPI • Pthreads • Java threads • Math libraries; ACML, SLATEC, MKL, SCSL, IMSL.

  4. Memory Architectures • Distributed Memory-A CPU can access its memory only • Example : A cluster made from Single CPU PC’s • Both the Cray XD1 and the SGI Altix 350 can run distributed memory programs. • Shared Memory-Multiple CPUs can access the same memory • Example: Dual CPU PC • The Cray XD1 can run shared memory programs on the two CPUs in a given node. • The SGI Altix 350 can run shared memory programs on the 16 CPUs in the compute nodes. • Hybrid – combines both approaches • Cray XD1 Example: Form a cluster out of Dual CPU Nodes (mostly distributed) • SGI Altix Example: Form a Cluster out of 16 CPU Nodes (mostly shared) (A Node = 1 copy of the operating system)

  11. Performance Comparison

  12. Torque/MOAB queue system • User commands • qsub – run a job • qstat – see status • checkjob – see job information • Queue Server Node • Server – keeps track of queues and jobs • Scheduler – chooses when/where to run jobs MOAB runs jobs to ensure maximum utilization of the system, without over-subscription, and ensures jobs get the requested amount of memory/CPUs. Compute node * MOM daemon – runs jobs and reports available CPUs/memory
