● 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
