Towards a distributed memory implementation of Sisal

Sisal is a functional language for scientific applications implemented efficiently on shared memory, vector, and hierarchical memory multiprocessors. The current compiler assumes a flat, shared addressing space, and the runtime system is implemented using locks and shared queues. This paper describes a first implementation of Sisal on the nCUBE 2 distributed memory architecture. Most of the effort is focused on altering the runtime system for execution in a message passing environment and providing the Sisal compiler with a distributed shared memory. The authors give preliminary performance results and outline future work
