| Summary: | ABSTRACT: The Arctic Region Supercomputing Center (ARSC) installed a single 8-CPU Cray SX-6 node, and made it available last August to the broader U.S. HPC community for benchmarking and testing. Our experiences of 6 months suggest that, to those accustomed to traditional Cray PVP systems, the SX-6 architecture and user environments are simultaneously familiar and peculiar. We also note that performance sustained by vectorizable user codes, per SX-6 CPU, has been gratifying while achieving additional speedup from multiple CPUs has proven more elusive.
