About Discoverer
PetaSC Bulgaria is a legal consortium combining the knowledge of our member organizations and more than 15 years of experience in applied science. Founders of the organization are Sofia Tech Park, National Center for Supercomputing Applications and the Strategic Center for Artificial Intelligence.
Our experience is concluding the operations of 2 supercomputers: IBM Blue Gene/P and HP HPC cluster. We have also engaged in 6 programs under the Partnership for Advanced Computing in Europe (PRACE), collaborating on over 13 projects with our initiative partners.
Our main objective is to foster better science for industrial applicability and facilitate the development of the next level European economy.
Architecture and parameters
- Discoverer is based on the ATOS BullSequana XH2000 architecture and features 12 BullSequana XH2000 racks.
- Each rack uses unique Direct Liquid Cooling (DLC) technology, which uses a combination of 90% hot water-based and 10% air-based cooling to remove excess heat from critical components while preventing condensation, minimising costs and environmental impact.
- Each BullSequana XH2000 rack can accommodate up to 32 DLC compute blades, up to 6x15kW DLC PDUs and 10 DLC InfiniBand HDR switches.
- There are currently 1128 compute nodes installed in the Discoverer, each with two AMD EPYC 7H12 64-core processors, for a total of 2256 CPUs.
- The number of processor cores is 144,384 where size of the RAM reaches 300TB.
- 2 PB of fast disk storage DDN space is guaranteeing optimal operability for store procedures.
- The system is safeguarded against power outages using an uninterruptible power supply (UPS) with a capacity of 1 MW.
- The whole complex weighs over 30 tons.
