Hardware Hardware Vendor 3Leaf Systems, Inc. Vendor URL http://www.3leafsystems.com Model 3Leaf Systems Voyager Platform Processor Quad-Core AMD Opteron(tm) Processor 8384 MHz 2700 # of Chips 32 # of Cores 128 # of Cores/Chip 4 HW Threading Enabled? No Procs Avail to Java 128 Memory (MB) 500090 Memory Details 128 x 4GB Registered ECC DDR2 667Mhz Primary cache 64KBI+64KBD Secondary cache 512KB per core Other cache 6MB per chip Filesystem ext3 Disks 1 x 4GB SCSI (classes) 1 x 12GB SCSI (OS) Other hardware Mellanox DDR Infiniband switch. The SUT utilizes 16 3Leaf Voyager boards, each with two Opteron sockets and an additional F socket for the 3Leaf ASIC. The ASIC handles the cache coherent memory access between the Voyager boards and is facilitated by the 3Leaf DVMM which is a very thin "bare-metal" hypervisor. Each Voyager occupies 1u rack space and thus the total form factor is 16u + 1u for the Voyager interconnect. The OS instance is standard RHEL 5.2. Total available resources for the machine are 128 cores and 512GB memory.
