The Oakland University (OU) central HPC Linux-based cluster (Matilda) is intended to support parallel, GPU, and other applications that are not suitable for individual computers. The Matilda HPC cluster consists of approximately 2,200 cores. All nodes are interconnected with 100Gbps InfiniBand networking.

The Matilda HPC cluster includes the following compute nodes:

  • 40 Standard Compute nodes, each with 192 GB of RAM and 40 CPU Cores at 2.50 GHz.

  • 10 High Throughout nodes, each with 192 GB of RAM and 8 CPU Cores at 3.80 GHz.

  • 4 Big Memory nodes, each with 768 GB RAM and 40 CPU Cores at 2.50 GHz.

  • 4 Hybrid nodes, each with capacity to include specialized accelerator cards or GPUs and 40 CPU Cores at 2.50 GHz.

    • Hybrid nodes currently have no cards added so function similar to Standard Compute nodes.
  • 3 GPU nodes, each with 4 NVIDIA Tesla V100 16G GPUs, 192 GB RAM and 48 CPU Cores at 2.10 GHz.

  • 1 Large Memory nodes, with 1.5 TB RAM and 40 CPU Cores at 2.50 GHz.


The system includes 690 TB of high-speed scratch storage using a high-performance parallel file system connected via 100Gbps Infiniband to each compute node.

Home directories, project space, and shared software reside on a Dell EMC Isilon H500, a storage system with integrated backup solution. Data is replicated to a Dell EMC Isilon A2000 located in a secondary data center with independent power and HVAC systems. The Dell EMC Isilon A2000 can also provide an archival mechanism to Amazon Web Services.

All Matilda HPC cluster nodes are interconnected with HDR100 Infiniband, delivering up to 100 Gbps of bandwidth and sub 0.6usec latency.


The Matilda HPC cluster is connected to the Oakland University campus network with 10 Gbps connectivity to provide access to storage systems and from researchers labs and workstations.


The Matilda HPC cluster includes a comprehensive software suite of open source research software, including major software compilers, and many of the common research-specific applications.

Data Center Facilities

The Matilda cluster is housed within the North Foundation Hall data center. This facility is equipped with fire suppression systems, a standby generator and environmental controls.


The Matilda HPC cluster services are provided through a collaboration with Oakland University Research Office and University Technology Services.
