Kielipankki tools and data to be moved from Puhti to Roihu

During summer 2026, Puhti will be replaced by Roihu, the new supercomputer at CSC. Puhti will be gradually retired according to the following tentative schedule:

• Roihu is scheduled to become generally available at the end of June.
• Puhti computing services will be shut down one month after Roihu general availability, by the end of July 2026.
• Puhti storage services and login node will remain accessible until October 15, 2026.

Language Bank tools on HPC

In the high-performance computing (HPC) environment at CSC, there is a small number of tools that are maintained by the Language Bank of Finland, in addition to the centrally installed tools. Most of these tools will be migrated by the Language Bank, some tools will be supported as part of the general services at CSC, and a few tools can no longer be supported in Roihu.

The following tools will continue to be offered by the Language Bank on Roihu:

• hfst
• hfst-morphologies
• praat
• udpipe
• enchant
• opensmile
• trankit
• heliots
• vrt-tools
• tsv-utils
• finnish-tagtools

The following tools will be offered centrally on HPC:

• ffmpeg
• libxml2, xslt1

The following modules will no longer be provided on Roihu:

• aalto-asr
• hfst-ospell
• finnish-parse (based on the Turku Dependency Parser, replaced by more recent tools)
• kaldi (used in the former Aalto-ASR toolkit)

Corpus copies on HPC

Until now, the copies of some of the downloadable resources in the Language Bank have been available on Puhti, to make them more conveniently accessible without downloading and transferring large datasets. We aim to keep these resource copies available in Roihu as well. In the new system, however, the resource copies will be provided as zipped archives.
