The World's most powerful Personal Computer:

Hi All here it is then

What a monster 13x GT200b's for some Cuda :haha: rofl


It has 4 Dual PCB'ed ASUS GTX 295's and 2 Single PCB'ed ASUS GTX 295's as where the main VGA is an ASUS GTX 275:

"This time the job was more complicated though, the new system features 13 GPUs and a custom BIOS from ASUS and Linux kernel hacks were required to get it operational. FASTRA II is 3.5 times faster than the original system and is likely the fastest desktop computer in the world."

They simply used every PCI-E 2.0 x16 slot on the mobo! And this is how

These were used to fit all the cards:


Which then gave this possibility:


So here a vid everyone

As for it's performance:


As power usage:


And here is why the GTX 275 was used as main VGA:

"The GeForce GTX 275 is used to connect to the screen, a single-GPU card had to be used due to technical reasons which restricted the FASTRA II from using more than 13 GPUs, more info about this can be found below."

"The system is theoretically capable of supporting 14 GPUs by inserting seven dual-GPU graphics cards but this didn't work as the system wouldn't boot due to memory allocation issues caused by the 32-bit BIOS. To deal with the issue, they worked together with ASUS to develop a custom BIOS that skips initialization of certain types of graphics cards during boot. To still get output from the system, one card must be of a different type and that's why they used a GeForce GTX 275. Due to this BIOS hack, the Linux OS kernel had to be modified to leave all memory address space allocation up to the operating system. Unfortunately FASTRA II still suffers from stability issues, it is capable of performing successful computations with all 13 GPUs simultaneously, but it regularly crashes. The stability issues seem to be related to problems with the NVIDIA driver and/or the changes made to the Linux kernel. The researchers hope the publicity surrounding the launch of FASTRA II will help them to get more support to solve these issues."

Just thought this would be cool to show, the GT200b's shall live on people.

Peace.
