CONSISTENT PERFORMANCE ASSESSMENT OF MULTICORE COMPUTER SYSTEMS

Performance assessment, through High-Performance Linpack (HPL) benchmark, of the quad-core cluster with InfiniBand interconnect recently acquired at LIT-JINR Dubna is reported. Corroboration with previous results [Gh. Adam et al., Rom. J. Phys., 53, 665 (2008)] shows that the HPL benchmark scales for single-core, two-core, quad-core chips and yields results fitting its intrinsic complexity under statistically relevant criteria. Free software implementations (OS and MPI) on multicore clusters at LIT-JINR and IFIN-HH resulted in relative performances comparable to those reported within the September 2007 issue of TOP500, the list of the five hundred most productive parallel computers in the world. 1
