Maple is a Cray cluster with 96 compute nodes, a total of 2,992 CPU cores, and 33 NVIDIA GPUs, and 10.4TB of memory. This cluster has theoretical peak of 140.6 TFLOPS. It is interconnected with Infiniband. This cluster is partially funded by the National Science Foundation (CHE-1338056).
The cluster originally consisted of 29 compute nodes, each with two 10 core Intel Xeon CPUs, 64GB of memory, and an NVIDIA Kepler K20 GPU.
The cluster was upgraded in 2017, 2018, and 2019, adding a total of 67 nodes, each with two 18 core Intel Xeon CPUs and 128 GB of RAM. Two of those nodes have two large memory NVIDIA GPUs.
Maple has much newer CPUs than Sequoia and Catalpa and does not share their software stack. Also, while all of our systems run SUSE Linux Enterprise Server (SLES), Maple is our only Cray system and our only system to use Bright Cluster Manager, so its operating system and some software is setup differently.
All Maple nodes have local hard disks, accessible in /tmp. The original nodes (cn001-cn029) have 1TB disks and all newer nodes (cn030-cn096) have 2TB disks.
