High Performance Computing

server room with server racks

The UTech High Performance Computing service at CWRU provides stable, multi-purpose, high performance computational resources that enables the modeling and simulation of various science, engineering, medical, and social computational research by allowing users to run many single or parallel jobs.

The HPC is a critical resource for an expanding spectrum of research. It enables investigators to solve large-scale, data intensive, advanced computational problems on topics across the disciplinary fields faster, more accurately, and more efficiently.

Operation of the HPC Cluster and its associate Service is guided by usage policies approved by the Advisory Committee on Research Computing. Please contact UTech Research Computing for additional information.

Associated RCCI Resources + Services


  • Consultation Services - RCCI can provide the necessary information about the existing Core facility (boilerplate language), suggest the appropriate computational hardware and storage for the proposal, including the necessary quotes, and execute the proposed computational plan upon the award being funded.

  • Big Data Cluster - RCCI can provide a separate cluster to work on Big Data by constructing the cluster with Cloudera Hadoop. Applications in this environment include: HDFS/Yarn, HBase, Spark, Hive, etc.

  • Secured Research Environment - RCCI provides a secured research environment to keep and to analyze protected data under PII, FISMA and HIPAA. Further information can be obtained by clicking on the link above.


  • External Resources - While our resource serves well for many research uses, it is not of adequate size to handle larger computational tasks that may require several hundred or several thousand simultaneous processors. For those larger jobs, there are other resources available to CWRU researchers that are both free and commercially available.

  • Visualization Resources - Case UTech research computing supports visualization activities for researchers throughout the Case community. In addition, research computing has computing systems that provide the means to produce, explore or share visualization materials.

Who manages the HPC Service?

  • The HPC Service Manager is Hadrian Djohari. He can be reached at hpc-support@case.edu.

How can I get the HPC Service?

  • After reviewing the Membership Options above, eligible faculty should complete the online application form. Contact hpc-support@case.edu with any questions regarding the account application process.

How do I cite the use HPC resources in my research work?

  • We ask that you acknowledge the use of the HPC system in your publications and presentations as
    • "This work made use of the High Performance Computing Resource in the Core Facility for Advanced Research Computing at Case Western Reserve University."
  • Please email references of your published research papers or poster presentations at <IMAGE OF hpc-support@case.edu>

Can I view the current status of the HPC cluster?

  • Those with an HPC cluster account and password can view the current status of the cluster here. Note: VPN is required to access this service from off-campus.

How is the HPC sustained and updated?

  • HPC services are funded through a mixture of UTech operating funds and faculty membership subscriptions. Subscriptions can be paid for through direct investment in HPC equipment or an annual charge per the amount of resources a researcher utilizes. UTech utilizes these funds to pay for licensing and infrastructure upgrades as necessary.

Where can I find more information about UTech Research Computing and the HPC?
