HPC Operating Environments
To bring HPC capabilities to desktop-bound engineers and scientists, the Cray CX1 supercomputer offers multiple operating environments:
Microsoft HPC Server 2008
Cray and Microsoft have partnered extensively to create a superior out-of-the-box experience for the HPC user. The Cray CX1 system ships pre-configured with Windows HPC Server 2008 along with installation routines that make configuration and setup a simple and straightforward process.
The Cray CX1 supercomputer with Windows HPC Server 2008 is an integrated solution stack that provides a simplified, common operating environment. This powerful combination offers consistent and integrated deployment, job submission, status and progress monitoring while delivering maximum compute performance and scalability, from workgroup HPC systems to some of the world's largest supercomputers, to the end user. Additionally, this scalable solution tightly integrates with existing desktop Windows infrastructures, allowing users to extend desktop technology and skills to the realm of HPC computing.
Windows HPC Server 2008 integrates with Windows Active Directory, security technologies and management and deployment tools. It supports traditional HPC MPI applications, as well as new interactive and service-oriented parallel applications using Microsoft .NET platform. In addition, Windows HPC Server 2008 easily integrates with existing Windows and Unix environments, making it an ideal platform for developing and running advanced HPC applications, including support for a high performance networking stack, C/C++, MPI, MPI.Net, F#, C#, Fortran, advanced debugging and tracing tools, including Vampir, along with Windows Performance Toolkit.

Red Hat Enterprise Linux
Red Hat Enterprise Linux (RHEL) is designed for enterprise deployments providing a cost-effective, flexible and scalable environment. It features support for shared cache and multi-core systems, kernel SMP locking enhancements for improved scalability and IPv4/IPv6 performance enhancements. RHEL supports very large high performance file systems with Global File System (GFS) and support for NSFv4. It is also interoperable with Microsoft Windows file and print (CIFS) systems through Samba. Finally, RHEL provides excellent compiler and debugging capabilities with GCC 4.1 and Glibc 2.4.
