vSMP Foundation and Linux

ScaleMP with vSMP Foundation enables you to aggregate commodity hardware (rack or blade based) into a large SMP capable of running any standard X86 Linux distributions.

ScaleMP is using standard virtualization techniques to aggregate separate physical system into a large virtual SMP system. A system running vSMP Foundation 3.0, can support up to 8,192 cores and up to 64TB of RAM.

ScaleMP has been working with the Linux community since 2004, contributing to improving the Linux Kernel to support large NUMA systems. As a result one can use today any standard x86 Linux Kernel above 2.6.16 and with the right configuration options, can achieve excellent performance.

ScaleMP has over 150 deployments/customers worldwide running a variety of distributions such as: RHEL, CentOS, SLES, Ubuntu, Debian, FedoraCore, OpenSUSE. ScaleMP tests and certifies many Linux distributions; for a formal list of supported operating systems see http://www.scalemp.com/spec

With such a system, one can run any x86 Linux code unchanged, while being able to leverage all the aggregated compute resourced (processor cores, memory, NICs, and hard drives). As vSMP Foundation aggregates the hardware as a single virtual system (SMP), from an operating system and application perspective, this is completely transparent, and as a result would allow you to manage a single OS instance.

ScaleMP customers are running a variety of applications, while achieving excellent performance:

  • Gaussian: A computational chemistry code which is OpenMP based and hence can only run on an SMP system
  • NAMD: An MPI-based molecular dynamics code
  • Matlab: Mathematical / numerical simulation software which takes advantage of large core counts and large amounts of memory
