Abstract
Cornell University has developed a group communications and membership
management tool, called the Ensemble system, which provides the basis
for introducing guarantees such as reliability, high availability,
fault-tolerance, consistency, security and real-time responsiveness into
applications that run on clustered parallel computers or high speed
networks. Ensemble tools are flexible, extremely transparent, and
achieve high performance. Our development started under Unix in 1995,
but by 1996 had enlarged to include NT as a primary target. This paper
reviews Ensemble and then discusses the technical issues that arose when
repositioning it to fit naturally and perform well under NT.
