Description
The LUMI system will be supplied by Hewlett Packard Enterprise (HPE), based on an HPE Cray EX supercomputer. The peak performance of LUMI is an astonishing 552 petaflop/s meaning 552 Petaflop/s peal, 375 Petaflop/s LINPACK. This figure makes LUMI one of the world's fastest supercomputers. For comparison, the world's fastest computer today (Fugaku in Japan) reaches 513 petaflop/s and the second fastest (Summit in the US) 200 petaflop/s (more information: www.top500.org). If LUMI's computing power was compared to normal laptops, it would require 1,5 million laptops together to reach the performance of LUMI. If these laptops were piled up, they would form a tower of over 23 kilometers high. LUMI will also be one of the most advanced platforms in the world for artificial intelligence (AI). With LUMI, it will be possible to combine AI, especially deep learning, and traditional large scale simulations combined with massive scale data analytics in solving one research problem. The number crunching capability of LUMI is accelerated by the GPU (Graphics Processing Unit) partition. It is based on the future generation AMD Instinct GPU. LUMI will be complemented by a CPU (Central Processing Unit) partition, featuring 64-core next-generation AMD EPYC CPUs. LUMI's data analytics partition has 32 an aggregated terabytes of memory and 64 visualization GPUs. This partition is used e.g. for visualization, heavy data analysis, meshing and pre/post-processing. LUMI's storage system will consist of three components. First, there will be a 7-petabyte partition of ultra-fast flash storage, combined with a more traditional 80-petabyte capacity storage, both based on the Lustre parallel filesystem, as well as a data management service, based on Ceph and being 30 petabytes in volume. In total, LUMI will have an astounding storage of 117 petabytes and an impressive aggregated I/O bandwidth of 2 terabytes per second. LUMI will also have an OpenShift/Kubernetes container Cloud platform for running microservices. All the different compute and storage partitions are connected to the very fast Cray Slingshot interconnect of 200 Gbit/s. The global bandwidth of the LUMI-GPU partition is 160 TB/s. The global Internet traffic would fit therein, in fact two times. LUMI takes over 150m2of space, which is about the size of a tennis court. The weight of the system is nearly 150 000 kilograms (150 metric tons).
