UNMC users have two free supercomputing resources.
Holland Computing Center (HCC) at Peter Kiewit Institute (PKI) in Omaha
The Research IT Office (RITO) has close working relationship with PKI. If you are planning on accomplishing some work on the supercomputers at PKI, please contact us. To learn more about the facilities at PKI, please visit the Holland Computing Center Web site.
XSEDE (Extreme Science and Engineering Discovery Environment)
It is a cyber infrastructure distributed across the US. XSEDE is a single virtual system that scientists can use to interactively share computing resources, data, and expertise. The XSEDE infrastructure has been established using funds from NSF ($121 Million). Using XSEDE, researchers can establish private, secure environments that have all the resources, services, and collaboration support they need to be productive. Visit here to see all resources offered by XSEDE. XSEDE supports 16 supercomputers and high-end visualization and data analysis resources across the country. It also includes other specialized digital resources and services to complement these computers.
UNMC has an XSEDE membership that makes it easy for all UNMC researchers to get free access to XSEDE supercomputers. If you want to apply for the user account, follow the instructions listed in this document.
******* Free On Demand Online Training for Supercomputer Users ********
High quality online workshops are available from Cornell University to all XSEDE supercomputer users. Please setup your free user account on XSEDE by following attached document. After creating user account (it will take about 1 business day), please go ahead and jump into the workshop material.
