VSC – Virtual Supercomputer – is an innovative high-performance cloud computing service. When a system’s full computing power is not being used by its owners, the power that is available can be provided to clients.

VSC provides a ready-made, fully-functional analogue of a physical supercomputer that is comprehensively equipped with software and requires no specific knowledge of software installation or setup procedures. This allows owners of supercomputer facilities and independent software vendors to reach customers that have never before had access to supercomputing power.
VSC is built on top of Clustrx the operating systems for HPC (high-performance computing) and borrows some technologies and approaches from forthcoming OS for distributed computing - Xpandrx.

Clustrx/Xpandrx are being developed as the part of Massive Solutions' strategy to build a model of system software for large heterogenous datacenters and future exascale. A low-level hypervisor runs mobile virtualised instances of OS-level services on physical servers and makes up a secure distributed interconnected layer. Every service can work within multiple virtual machines that run on multiple physical servers in a management facility. Each piece of hardware and software in the whole cluster or cloud are under control of a real-time monitoring subsystem. The granularity and integrity of the monitoring data enables the delivery of a complex computing functionality.
VSC instances use a lightweight virtualisation scheme that provides a secure, isolated network environment to each virtual cluster, without degraded performance. VSC instances that are ready for use will be available immediately through an online shop, which will be a marketplace for infrastructure providers to offer computing power and for independent software vendors to offer their software packages.
