No Procs Avail to Java 128 Memory (MB) 786432 MB Memory Details 16 x 2 x 6 x 4 GB DDR3-1066R, ECC, CL9 Primary cache 32 KB I + 32 KB D on chip per core Secondary cache 256 KB I+D on chip per core Other cache L3: 8 MB I+D on chip per chip Filesystem xfs Disks 16 x 150 GB SATA, 7200 RPM Other hardware Other Cache: - ScaleMP vSMP Foundation manages cache coherency between the InfiniBand-connected systems via multiple concurrent memory coherency mechanisms, on a per-block basis, based on real-time memory activity access patterns. - This mechanism reserves 96 GB of the main memory across all boards (distributed), which is used as a 4th level cache. Hardware Details: - System was aggregated using 16 X Dell PowerEdge M610. - The servers were connected with Melanox InfiniBand QDR and a QDR switch. CPU Characteristics: Intel Turbo Boost Technology not-enabled: As the prerequisites listed below for enablement of this technology did not exist. The prerequisites for Turbo Boost Technology are: - Hardware: Enabling Turbo Boost Technology require BIOS setting. - Software: OS needs to be ACPI-aware and set P0 power state.
