The Tianlong computing cluster

Tianlong is the computing cluster of the PMC group of the CPHT laboratory funded as part of the Simons Foundation. All the nodes of the cluster are interconnected by a high speed QDR InfiniBand network.

Important

In 2022, all Tianlong nodes have been integrated into the Cholesky cluster on a dedicated QDR infiniband network.
