High Performance Computing
Puhti is a supercomputer that caters to a wide range of use cases. It has a powerful CPU partition with almost 700 nodes with a range of memory sizes and local storage options, all connected with a fast interconnect. Puhti allows the user to reserve compute and memory resources flexibly, and the user can run anything from interactive single core data processing to medium scale simulations spanning multiple nodes.
There are also 80 GPU nodes, with total of 320 GPUs. This partition is suitable for all kinds workloads capable of utilizing GPUs, even heavy AI models that span multiple nodes.
Puhti has wide selection of scientific software installed.
Mahti is a supercomputer designed for massively parallel jobs requiring large floating point performance and a capable interconnect. The system has in total 1404 nodes equipped with powerful AMD Rome CPUs. These are connected with a fast interconnect, allowing jobs to scale across the full system. In Mahti user reserves full nodes so that the jobs can extract full performance from each node. Mahti is in particular geared towards medium to large scale simulations requiring Petaflops of compute power. Also smaller parellel workloads that are able to use full nodes efficiently can utilize Mahti.
- The call for Pilot Projects was open until 31st January 2020
- The Pilot Usage period is expected to start in mid May
- The general availability of Mahti for all users is expected in June.
CSC offers a new common data management solution Allas for both new and old infrastructure. This system is based on CEPH object storage technology and it provides 12 PB of storage capacity and will be the backbone for providing a rich environment for storing, sharing and analyzing data across the CSC compute infrastructure.
