Product brief description:
Supercomputer systems of hybrid architecture offer the following architectural solutions:
1. Tera-scale capacity range.
2. Hybrid meta-cluster architecture with homogeneous computational nodes or cluster architecture with hybrid computing nodes with coprocessors.
3. Computational nodes work on the basis of classic multi-core processors with x86-64 architecture and/or specialized processors (coprocessors) of Cell type, graphics processor- accelerator (GPU), etc.
4. The basic design and technological solutions:

  • Form factors are: 1U, 2U, blade-servers;
  • Posts are: 19 " and up to 44 U high;
  • Air cooling system.

Three models have been made:

  • The "SKIF UIIP" cluster. It represents meta-cluster consisting of two parts: the blade technologies-based cluster (blade-cluster) and the Cell technology-based cluster (Cell-cluster). The Cell-cluster of "SKIF UIIP" supercomputer has 8 dual processor computational nodes based on PowerXCell 8i 3.2Ghz processors. Cell-cluster peak performance is: Rpeak = 1638 Gflops (double); Rpeak = 3276 Gflops (single). Computational nodes of blade-cluster are made on the basis of T-blades dual-processor servers developed by the «T-Platform» Russian company and have 4 Intel XEON E5472 3.0GHz core processors. The total number of computational clusters: 50; the total number of cores: 400. Peak performance of blade-cluster of "SKIF UIIP" supercomputer is 5.0 Tflops. Actual efficiency of "SKIF UIIP" supercomputer prototype according to Linpack test for 52 units (including two control units) on the blade-servers is 4027 Gflops. The Ueff cluster efficiency indicator is 80, 67%. The "SKIF UIIP" cluster takes 47th place in the 14th edition (from 29.03.2011) of Top50 list of CIS the most powerful supercomputers.
  • The "SKIF-GPU” cluster. The "SKIF-GPU» cluster was created in 2010. Its computational nodes and other modules are located in two 19”

44 U-height posts of original design.The "SKIF-GPU» cluster has 34 computational and 2 control nodes. Each node contains of two
4-core Nehalem Intel Xeon X5570 2,93 GHz processors with х86-64 architecture and GPU NVIDIA GeForce GTX 295 graphic engine. The cluster peak performance cluster for graphic engines if making calculations with floating-point of single precision is not less than 60.0 TFLOPS; with that of double precision - not less than 5.0 teraflops. Actual efficiency of
"SKIF-GPU” supercomputer prototype  according to the Linpack test for 36 units without graphic engines is 3025 Gflops. The Ueff cluster efficiency is 89,62% of the peak 3375.36 Gflops. The "SKIF-GPU " cluster takes 45th place in the 13th edition (from 21.09.2010) of Top50 list.

  • The "SKIF-GRID" cluster. The cluster uses advanced technical solutions based on the 12-core AMD Opteron processors with x86-64 architecture and graphic processors-accelerators. "SKIF-GRID" cluster computational nodes and other modules are located in one 19 "44 U-height post of original design. "SKIF-GRID" cluster’s efficiency is the highest among all the Belarusian "SKIF" models. Its peak efficiency (with 36 computational nodes and 2 control units) without taking into account the acceleration through graphic engines is 8.0 teraflops. The Linpack test efficiency indicator is 82,15%. The "SKIF-GRID" cluster takes 40th place in the 14th edition of the Top50 list (29.03.2011).

    Main advantages:
  • high performance with high efficiency;
  • high packing density, small size;
  • low power consumption in comparison with other supercomputers of the same class
