Notes and other links
a. Workflow: loosely coupled parallel applications that consist of a set of computational tasks linked by data- and control-flow dependencies.
b. A parallel file system and high-speed interconnect would make dramatic performance upgrades. Recently Amazon released a new resource type including a 10Gb interconnect.
c. There is a movement towards providing academic clouds, such as FutureGrid or Magellan.
