Service breaks and reduced capacity due to installing the new infrastructure

Reduced capacity

After the decomissioning of Taito Sandy Bridge nodes, computing capacity is reduced until the new environment is taken into use. To compensate this, we will allow smaller workloads on the Cray XC40 supercomputer Sisu; the minimum number of nodes in "small" batch job queue will be reduced from three to one. Access to Sisu can be applied by the project manager of CSC project in the customer portal at

The Haswell nodes on Taito will remain in the use until the end of 2019.

Supercomputer Sisu will be decomissioned on 16th of August 2019.
