A new Cray X1 system arrived at the NAS Facility on April 20. This new parallel vector processing system incorporates the best features of Cray Inc.'s previous vector and massively parallel processing systems. The X1 has 16 multi-stream processors (MSPs) with a peak performance of 204.8 gigaflops per second. The system is expandable to 64 MSPs without the need for additional cabinets. This highly scalable system will support a variety of parallel programming models like standard MPI, co-array FORTRAN, unified parallel C, SHMEM and OpenMP, and will augment the other parallel systems at NAS.
The system was booted the afternoon it arrived, and staff are working to install standard supported software and to secure the system for operation in the NAS environment. The system, specifically designed to meet the needs of the high-end users, will be made available soon to selected users. A training class for system developers is being created and will be offered to users in the near future.
