Compute Nodes
Work in progress
Barbora NG documentation is a WIP. The documentation is still being developed (reflecting changes in technical specifications) and may be updated frequently.
The launch of Barbora NG is planned for July 2026. In the meantime, the first computational resources have already been allocated in the latest Open Access Grant Competition.
Barbora NG is a cluster of x86-64 Intel-based nodes built with the BullSequana XH3000 Computing technology. The cluster contains 141 standard (i.e. non-accelerated) compute nodes.
