This document introduces high-performance computing (HPC), which involves dividing large problems into smaller parts that are distributed across multiple distinct computer processors working together on the same calculation. There are two main types of HPC: internal HPC using a cluster of computers owned by an organization, and external HPC using cloud computing resources from an external provider. The document then discusses factors like performance, flexibility, investment costs, and support for internal versus external HPC options.

1. HIGH PERFORMANCE
COMPUTING
A N I N T R O D U C T I O N T O

2. HIGH-PERFORMANCE
COMPUTING INVOLVES MANY
DISTINCT COMPUTER PROCESSORS
WORKING TOGETHER ON THE
SAME CALCULATION
LARGER PROBLEMS ARE DIVIDED
INTO SMALLER PARTS AND
DISTRIBUTED AMONGST THE
MANY COMPUTERS
USUALLY CLUSTERS OF QUASI-
INDEPENDENT COMPUTERS
WHICH ARE COORDINATED BY A
CENTRAL SCHEDULER

3. INTERNAL HPC
OUTSOURCE HPC SYSADMIN
NO HARDWARE INVESTMENT
PAY-AS-YOU-GO
EASY TO MIGRATE TO NEW
TECH
REQUIRES IN-HOUSE
EXPERTISE
MAJOR INVESTMENT IN
HARDWARE
POSSIBLE IDLE TIME
UPGRADES REQUIRE NEW
HARDWARE
EXTERNAL HPC

4. "CLOUD COMPUTING": VIRTUAL MACHINES, DYNAMIC
ALLOCATION OF RESOURCES IN AN EXTERNAL RESOURCE
LOWER PERFORMANCE (VIRTUALISATION), HIGHER FLEXIBILITY
USUALLY NO CONTRACTS NECESSARY
OFTEN HAVE TO DO ALL YOUR SYSADMIN
LOW SUPPORT, HIGH CONTROL
