gVirtuS: the first beta release

Author: cjg

We are proud to announce the first beta release of gVirtuS.

gVirtuS allows an instanced virtual machine to access GPGPUs in a transparent way, with an overhead  slightly greater than a real machine/GPGPU setup. gVirtuS is hypervisor independent, and, even though it currently virtualizes nVIDIA CUDA based GPUs.

The software, developed for research applications, is provided as it is.

We encourage using and testing it in order to collect useful feedbacks and suggestions.

Take a look to the gVirtuS project page: http://osl.uniparthenope.it/projects/gvirtus/.

VMSocket: a mechanism to expose UNIX Sockets in KVM Virtual Machines

Author: cjg

VMSocket is a mechanism to expose UNIX Sockets (sockets in AF_UNIX domain) from the host operating system to the KVM’s virtual machines.

It provides a really fast communication channel between host and guests os. It can ben used for communication that needs to be fast, such as HPC (High Performance Computing) software solutions and so on.

The socket is bounded on the host os and the guests can connect to the socket using special drivers. At this time only the driver for linux is ready.

The sources of the patched qemu to support vmsocket are found on: http://github.com/cjg/qemu/tree/vmsocket/.
