Join us on Thursday January 20th at 3 pm MST for an RMACC town hall about Cumulus a cloud computing resources for researchers available to both CU Boulder and RMACC affiliates.

The Rocky Mountain Advanced Computing Consortium (RMACC) is a collaboration among academic and research institutions located throughout the intermountain states. Our mission is to facilitate widespread effective use of high performance computing.

CUmulus is a cloud computing resource that enables researchers to create applications and workflows that may not fit as well into the traditional high performance computing environment. CUmulus offers the ability to create and administer custom Linux virtual machines (VMs) with the following characteristics:  

  • Convenient access via a web-based console for creation, management and monitoring of VMs  
  • Flexible configurations for CPUs, memory and storage on VMs 
  • The ability to assign "floating IPs" to VMs that require external access (websites, science gateways) 
  • High availability in the event of underlying hardware failure 

Examples of Appropriate Use Cases  

  • Workflow management software that monitors/schedules jobs on Summit, Alpine, or Blanca 
  • Workflows that cannot run on Summit, Alpine or Blanca 
  • Websites that require access to CURC resources 
  • Research database/website application that queries data stored on CURC PetaLibrary 
  • Web-based research “Hubs” (JupyterHub, Shiny Apps)

Cumulus is a free-to-use system where:
- 80% of cycles: CU Boulder faculty, staff, students and affiliates
- 20% of cycles: RMACC affiliates
