Extending catamount for multi-core processors.
Suzanne M. Kelly, John P. VanDyke, Courtenay Vaughan · 2007
The XT3 Catamount Virtual Node (CVN) implementation was based on the dual processor support in ASCI Red’s [1] Cougar Light Weight Kernel Operating System. That solution was limited to no more than 2 virtual nodes per physical node. This paper describes the design for extending Catamount to support more CPUs per node. It identifies the areas needing modification and the selected resolution. Some preliminary performance results are provided.
