RSC Packs a Petaflops of Xeon Phi in a Rack
Like many top-end systems created today, the PetaStream is a hybrid design, and in this case it mixes a modest number of Xeon processors from Intel with a much larger number of Xeon Phi X86 coprocessors to get more than 1 petaflops of aggregate double-precision number-crunching power into a single rack.
99% BAD HARDWARE WEEK: Phi SC5120D Coprocessor with 60 cores. 245W TDP
Price at introduction $ 2700+. Cabinet price $ 5M, Overall power 400+ kW
- The co-processor does not support MMX, SSEx and AVX instructions
- The co-processor includes 8 GB of on-board GDDR5 memory with effective speed 5.5 GT/s
- Peak performance is 1,011 GFLOPS for double-precision operations
- The card is passively liquid cooled
- Card with PCI Express 2.0 x 24 card 230pin
COP part number is an OEM/tray co-processor Clock 1053 MHz
SMC means node controller .NVIDIA uses the terms "node"and streaming multiprocessor interchangeably.
Thus Petastream architecture. Note however that this chip remains essentially coprocessor.
Intel's QLogic Infiniband 312G IB EDR for module connections.
Sounds boring. Latest chip version is able in turbo mode 1,33 Tflops at 300W
