PET Summer Institute Kim Kido | Univ. Hawaii Manoa

Thursday, July 27 ● Intro to parallel computing ● Intro to MHPCC ● Intro to IBM SMP hardware ● Intro to SQUALL

Introduction to Parallel Computing Useful for analyzing complex problems requiring massive amounts of computation that can be divided into independent tasks

Introduction to Parallel Computing ● Use of multi-processors to complete a task ● Classification systems – How processor exectutes instructions: SIMD, MIMD – Memory type (shared, distributed) – Number of processors – Symmetric/asymmetric

IBM SMP Hardware Overview ● Symmetric Multi- Processors ● 2+ identical processors connected to single shared memory ● Workload efficiently balanced by moving tasks between processors

IBM SMP Hardware Overview ● Only one processor can access memory at a time ● Alternatives – NUMA – Asymmetric – Beowulf (computer- clustered)

Introduction to MHPCC ● Air Force Research Laboratory Center managed by UH ● Provides >10,000,000 hours of computing time annually Maui High Performance Computing Center

Introduction to MHPCC ● Engineering ● Meteorology ● Biology ● Computer science Fluid pathlines about Predator B fuselage. General Atomics Aeronautical Systems, Inc

Introduction to SQUALL ● 2-node, 32 processor IBM SP system ● Available to users that don't meet DoD HPCMP access requirements – Unclassified – Non-sensitive ● Designed for government, commercial, academic users ● Used in institute to run sample programs
