PEARL Service User Documentation¶

Overview¶

PEARL is a high-performance computing cluster, designed primarily for Deep Learning and AI research. At its core are two NVIDIA DGX-2s. Each DGX-2 utilises 16 Tesla V100 GPUs with a total of 512GB of GPU memory. Each also has 1.5TB of system RAM, two Intel Xeon Platinum CPUs and 30TB of NVME SSD local storage. The DGX-2s are connected over 100Gbit/s EDR InfiniBand to two Boston Flash-IO Talyn servers which together provide half a petabyte of NVMe storage.

It is run by STFC’s Scientific Computing Research Infrastructures Group on behalf of the Alan Turing Institute and it is hosted at STFC’s Rutherford Appleton Laboratory.
