Research Clusters
Nova
Originally Nova cluster consisted of compute nodes with multicore Intel Skylake Xeon processors, 1.5TB or 11TB of fast NVME local storage and 192GB / 384GB / 3TB of memory. Five of those nodes also have one or two Nvidia Tesla V100-32GB GPU cards. In 2021 the cluster has been expanded with AMD nodes, each having two 32-Core AMD EPYC 7502 Processors, 1.5TB of fast NVME local storage and 528GB of memory. The new GPU nodes in addition have four NVidia A100 80GB GPU cards. The 2022 expansion consists of 54 regular compute nodes (with two 32-Core Intel 8358 processors, 1.6TB of local storage and 512GB of memory each) and 5 GPU nodes with two 24-Core AMD EPYC 7413 processors, eight A100 GPU cards, 960GB of local storage and 512GB of memory each.
The three service nodes include login node, data transfer node and the management node.
Large shared storage consists of six file servers and twelve JBODS configured to provide either 338TB of backed up storage or 457TB non-backed up storage per server.
All nodes and storage are connected via Mellanox EDR (100Gbps) switch.
Additional nodes can be purchase by faculty using the Nova Cluster Purchase Form (need to be logged into Okta in order to access the form).

Condo Cluster
Condo Cluster consists primarily of 134 SuperMicro servers each with two 8-core Intel Haswell processors, 128 GB of memory and 2.5 TB of available local disk. In addition to these compute nodes there are three large memory nodes. Two large memory nodes have four 8-core Intel Ivy Bridge processors and 1 TB of main memory. Third large memory node has four 10-core Ivy Bridge processors and 2 TB of main memory. All nodes and storage are connected via Intel/Qlogic QDR InfiniBand (40 Mb/s) switch. There is also an accelerator node containing a pair of NVIDIA Tesla K20c GPU cards.
The three service nodes include login node, data transfer node and the management node.
As of July 1, 2021 access to the cluster is free for all ISU faculty and their groups. To request the access, faculty fill out the form.
