Project Results

High-Performance Fault-Tolerant Distributed Shared-Memory for Linux-based PC clusters
The project aimed at exploring the potential of VIA-based interconnect in providing a robust and efficient distributed shared memory environment on linux-based clusters. The work was successfully completed and the results are excellent.

The DSM runtime package for Linux-based clusters of PCs can be downloaded from here. The key feature of this package is that it virtually transforms a Linux-based cluster into a shared-memory parallel programming environment identical (from the programmer's point of view) with the multiprocessor one. A paper describing the implementation and the performance at the protocol will be presented at the 4th Annual Linux Showcase & Conference, Atlanta.

We have also developed a highly scalable fault tolerance scheme based on independent checkpointing exclusively. A description of this work can be found at
