Implementing CSC's next generation computing and data management environment

Topical issues

  • Mahti pilot usage starts on 6.7.2020, general availability in August 2020
  • Taito general availability ended 31.12.2019, more information below.

Taito and HPC archive decommissioning

As CSC's new supercomputer Puhti and Allas object storage are now available and Taito and HPC archive are about to close, we advice you to carefully read the recent news published on this topic:

Please make sure that your workflows run on Puhti, and to move all relevant data to Allas (or elsewhere) from home, work and project directories. Please read the migration tutorial for information on how to move data from Taito in our user guide: 

To ease the transition to Mahti, CSC will operate Taito with limited support and low service level in early 2020. In practice it means that

  1. Support and user documentation is not available for Taito in 2020 (support for data migration is provided)
  2. New features are not implemented, and new software is not installed  
  3. Taito, or parts of Taito, may be permanently closed at any time with no warning. 

HPC archive service will also be shut down later in 2020. No new data should be written to archive anymore. In January 2020 the archive will be set in read-only mode. For larger datasets (more than 1 TiB) we kindly ask you to contact CSC servicedesk so that the datatransfers can be done efficiently. Further details on transferring data from HPC Archive will be provided later.

Supercomputer Puhti is now available for researchers

CSC chose Atos as the single vendor to deliver the next CSC computing environment that consists of the next-generation supercomputer and data management systems. 

The new environment will be deployed in two phases.

In the first phase, a new air-cooled supercomputer Puhti and data management system Allas were installed in 2019. The first phase includes

  • A supercomputer partition with total peak performance of 1.8 Petaflops.
  • A partition for Artificial Intelligence research with total peak performance of  2.7 Petaflops from GPUs.
  • A new common data management solution for both new and old infrastructure. This system is based on CEPH object storage technology and it provides 12 PB of storage capacity.

In the second phase, a new  liquid-cooled Atos BullSequana XH2000 supercomputer Mahti will be installed and taken into use in 2020. The peak performance of Mahti is 7.5 Petaflops.
