RSC Group, a leading four-year-old developer and integrator of high performance computing (HPC) solutions in the former Soviet Union, announced last week that it has set a new world record of computing density of 1 petaFLOPS per server rack – five times greater than the company’s prior record of 211 teraFLOPS per rack set earlier this year on its RSC Tornado supercomputer architecture.
A petaFLOPS is a 1,000 trillion floating point operations per second.
PetaStream, the group’s proprietary solution, contains 1,024 computing nodes, each built on a 60-kernel Intel Xeon Phi 5120D coprocessor with 8GB of high-bandwidth GDDR5 memory. The nodes are interconnected, using a high speed Infiniband FDR network, and each rack is equipped with a liquid cooling system capable of removing 400kW of heat.
In addition to the nodes, there are up to 640 solid state drives (SSD) that can be installed in every rack.
The combination of these and other innovative features has resulted in what RSC refers to as a “revolutionary high-density HPC solution capable of processing over 250,000 execution threads in a single rack based on x86 architecture.”
