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

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
