Server without any video card
Hello !!
I need to buy and install a powerfull linux computing server machine for image processing applications, but I have some doubts concerning the X11. The problem is that a server machine usually is not coming with a Video card (or it has a simple one), so I was wondering :
1) if could be possible to install the X11 in the computing server (without any video card) in order to open remotely graphical applications (i.e. GUI) needed for the data management and visualization ?
2) If I install a "poor/cheap" video card in order to be able to install X11 on the server, and run remotely a GUI application from my workstation with a powerful video card, which video resolution will be used, the server resolution or client resolution and capabilities ?
I hope somebody can help me with my doubts.
Thanks,
JM
Server and Video Cards to Image processing.
Ohhh, guys, you're so fast !
If I where you I would simply avoid this kind of configuration because of the laggies of the frame buffer when generated by a simple X proccess in memory by the CPUs, and afterall, if you are planning to use OpenGL apps, sorry, until we have the final free OpenGL drivers for Nvidia or ATI, better use one of those cards with their respective blobs (sorry again...), the video cards framebuffers from ATI and Nvidia will always render images faster than most of processors in memory. Another case is when you need total precise results. (Comformant Image Rendering) But even in this case, I don't know exactly what kind of app you will use, but you have also the option for OpenCL programming for image processing, wich will give you faster results without sacrificing precision. Some OpenGL processing and rendering in different videocards could possibly give you different results because of the algorithms, but CPUs and OpenCL processors are very precise.
