Implementation and Evaluation of Specific Data-Intensive Scientific Applications on the FT64 Stream Processor

The stream architecture is one of the emerging architectures that address the memory-wall problem of modern processors. While it is successful in the domain of multimedia, its efficiency to scientific applications is increasingly concerned. This paper implements the stream programs for some data- intensive scientific programs and evaluates the performance on the FT64 stream processor, which is the first implementation of a 64-bit stream processor for scientific computing. The stream programs are optimized against the memory hierarchy of FT64 to minimize the expensive off-chip memory transfers. The preliminary results show that FT64 is efficient for these applications.
