Early experiences and performance of the Intel Paragon
Experiences and performance figures are reported from early tests of the 512-node Intel Paragon XPS35 at Oak Ridge National Laboratory. Computation performance of the 50 MHz i860XP processor as well as communication performance of the 200 megabyte/second mesh are reported and compared with other multiprocessors. Single and multiple hop communication bandwidths and latencies are measured. Concurrent communication speeds and speed under network load are also measured. File I/O performance of the mesh-attached Parallel File System is measured. Early experiences with OSF/Mach and SUNMOS operating systems are reported, as well results from porting various distributed-memory applications. This report also summarizes the second phase of a Cooperative Research and Development Agreement between Oak Ridge National Laboratory and Intel in evaluating a 66-node Intel Paragon XPS5.
