Calculation server setting log

This is a log of a calculator which the author maintains. The machine conditions are as follows:

Since Tesla C2075 is very new GPU, it could not be detected by Fedora9 which was installed in the computer. I changed to the CentOS-6.2 for the aspect of security and convenience of the use. Now both GPUs are detected by the OS.

Virtual-GL setting

Virtual-GL is a system which send Open-GL application images from a host computer to cliants' machines.
Just using X-window system, we don't have to install. However, in the case of using graphical-rich process, namely, application with Open-GL from other computer, the X can't send images. In this case, we have to install another graphic transportation process, and hence we use Virtual-GL. We put setting log here.

Virtual-GL can be downloaded from the Virtual-GL web page.
There are documentation and you'll get a manual.

We need softwares both host (logined machine) and cliants (login machine). There are no setting in the cliants, just using /opt/VirtualGL/bin/vglconnect to login to the host computer (OSX, Linux).
There are some settings in the hots. We have to do following things to set machine configuration (see user's guide above):

  1. Shutdown X, in the case of CentOS #init 3
  2. Run #/opt/VirtualGL/bin/vglserver_config (We selected all option "YES")
  3. Restart X, #init 5 (CentOS)
  4. We have to change /etc/group to add user group to the vglusers group.

Normaly, it will be enough to do. As libglx.so is not newest in our case, we sysmbolic linked /usr/lib64/xorg/modules/extensions/libglx.so to libglx.so.295.53.
Additionally, we only installed CUDA device driver on the host, and hence we had to install normal device driver to run Open-GL.

In the case of processing a software with VirtualGL, type as follows:
$/opt/VirtualGL/bin/vglrun "application name"
