On line visualization or combining the standard ORNL PVM with a vendor PVM implementation

摘要

Vendor implementations of PVM provide optimum performance on multicomputers. However, such implementations may lack interoperability. Developing of a real time display for a LGA simulation on Hitachi SR2201 parallel computer required a connection between the calulating part running on SR2201 and GUI running on a graphics workstation. A native PVM could not provide it. We proposed to use ORNL PVM to facilitate the connection and at the same time to use the native PVM for effective internal communication. Performance evaluation of this approach and practical results are presented.
