The Condor Project (Established 85)

• Distributed Computing research performed by a
  team of 40 faculty full time staff and students
  who
• face software/middleware engineering challenges
  in a UNIX/Linux/Windows/OS X environment
• involved in national and international
  collaborations
• interact with users in academia and industry
• maintain and support a distributed production
  environment (more than 2300 CPUs at UW)
• and educate and train students.
• Funding DoE NASA NIH NSF EU INTEL
• Micron Microsoft and the UW Graduate School

• Since the early days of mankind the primary
  motivation for the establishment of communities
  has been the idea that by being part of an
  organized group the capabilities of an individual
  are improved. The great progress in the area of
  inter-computer communication led to the
  development of means by which stand-alone
  processing sub-systems can be integrated into
  multi-computer communities.

Claims for benefits provided by Distributed
Processing Systems

• High Availability and Reliability
• High System Performance
• Ease of Modular and Incremental Growth
• Automatic Load and Resource Sharing
• Good Response to Temporary Overloads
• Easy Expansion in Capacity and/or Function

Benefits to Science

• Democratization of Computing you do not have
  to be a SUPER person to do SUPER computing.
  (accessibility)
• Speculative Science Since the resources are
  there lets run it and see what we get.
  (unbounded computing power)
• Function shipping Find the image that has a
  red car in this 3 TB collection. (computational
  mobility)

Good old Batch

• Dispatch and forget
• Job Control Language (JCL)
• Job steps
• Advanced (eager) binding of date sets
• Resource requirements
• Multiprogramming
• Time Sharing
