FATCOP: A Fault Tolerant Condor-PVM Mixed Integer Programming Solver [PDF]

open access: yes, 1999
We describe FATCOP, a new parallel mixed integer program solver written in PVM. The implementation uses the Condor resource management system to provide a virtual machine composed of otherwise idle computers.
