The European High-Performance Computing Joint Undertaking (EuroHPC JU) has unveiled the upgrade to the Discoverer supercomputer, hosted in Sofia Tech Park in Sofia, Bulgaria.
The upgrade, which will see the system renamed Discoverer+, consists of a new GPU partition, an additional UPS system, and a storage capacity increase.
Discoverer is the first EuroHPC JU supercomputer to get a major upgrade.
The BullSequana XH2000-based system was previously capable of 4.5 petaflops/5.94 peak and had two petabytes of storage. It consisted of 1,128 compute nodes, each relying on two AMD’s Epyc Rome CPUs.
The upgrade has seen four DGX H200s added to the supercomputer, with each DGX system comprising eight H200 GPUs with two dual Intel Xeon Platinum 8480C processors.
Plans to upgrade the system were first announced in October 2023, with the new GPU partition and flash storage making Discoverer compatible with AI workflows such as neural network training, digital twin simulations, LLM training, and image recognition.
A 5.1PB Lustre file system and a 273TB Weka storage solution have also been added.
“The Discoverer+ upgrade represents an advancement for both the European and Bulgarian HPC and AI communities," said Rafal Duczmal, chair of the EuroHPC JU governing board. "Bulgaria has consistently demonstrated its commitment as a European partner in the EuroHPC JU, beginning with its Council Presidency in 2018, followed by the Discoverer project, and most recently, through substantial investments in its own AI factory.”
