Reference: PSNAP 1.2 is an Open Source test to measure OS Interference and is available at the public website: http://www.ccs3.lanl.gov/PAL/software/psnap/ OS Interference in HPC Server 2008 R2 is less than what is seen in a LINUX environment run on an identical HW Configuration . Both Windows HPC Server 2008 R2 and LINUX benchmarks were run on the 16 Node Acer Blade System (Intel Nehalem CPU 5570 2.93 GHz (Dual-Processor, Quad Core), 24GB (1333 MHz), Mellanox Infiniband) - GAMBRINUS (Fraunhofer SCAI, Germany).
