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/.

This is essentially a manual installation but thanks to DKMS, Dynamic Kernel Module Support, it isn’t required anymore to reinstall the driver at every kernel update.

Author: cjg

Although  I use a computer since 2001 I had not experienced directly the existence of viruses, and also I was feeling that a default installation of the OS could give an almost secure environment. This was because since May 2003 I was using  always and everywhere a GNU/linux based OS and because in the first two years, when I used Windows ME (shipped with the computer), I hadn’t an Internet connection (at that time there were only dial-up, and it was too slow and too expensive), there weren’t usb memory stick and cd-burner were really really expensive, so although my OS could be vulnerable there were no vehicles of transmission.
