Operating Systems

The Center has experience with multiple operating system environments.

CentOS

CentOS is among the operating systems CAC runs on high-performance computing clusters. CentOS is an Linux distribution derived from sources freely provided to the public by an enterprise Linux vendor.

Red Hat

CAC has experience running Red Hat Enterprise Linux on multiple HPC clusters. The Chairman and CEO of Red Hat spoke at Cornell on the impact of open source technologies. Red Hat’s other affinity with Cornell is its name. Company founder, Marc Ewing, was given a Cornell lacrosse team cap (with red and white stripes) while at college by his grandfather. It was his favorite hat. He lost it somewhere in Philadelphia in his last year of school and named the company “Red Hat” to memorialize his Cornell hat.

Microsoft

CAC was instrumental in helping Microsoft to enter the high-performance computing market. The built-in scheduler in Microsoft's HPC product was modeled after a CAC reference implementation. Today, CAC is operating Windows HPC clusters for the Computational Biology Service Unit, the Cornell Fracture Group, and the Turbulence and Combustion Group.

Apple

CAC operated an Apple cluster running Mac OS X Server for computational biologists from the USDA Agricultural Research Service.

Other Operating Systems Experience

Center staff previously ran UNIX operating systems, including IBM AIX and SGI IRIX.

Operating Systems Research

The Operating Systems group at Cornell’s Department of Computer Science performs fundamental research on the design and implementation of operating systems.
