So I have been working for several years on a concept based on my frustration with motherboard limitations support beyond their onboard CPU's. The theory I was taught and seems to still hold true (mothers can have multiple children, but children can't have more than one mother) MB = mother, CPU= child. All jokes with inbreeding, adoption and Bruce Jenner aside, this has proven to be a good rule of thumb. Multiple CPU support is limited by the number of CPU's among other performance limitations. I set out to create what I coined as a FatherBoard (not sure if it is a term used elsewhere). The theory was a father could have multiple children from numerous mothers. After creating a prototype based on ASUS | AMD 64 boards, honing my soldering skills, and spending more time in Windows XP than any human should ever endure, I'm hung up on... yep you guessed it. The video cards on each board (current prototype is 4 boards) will not display a single GUI interface. The processors have been mostly configured using a traditional master | slave configuration; but unless a green screen OS is due for a mainstream comeback, the FatherBoard dream will end up in the Recycle Bin with my other OCD endevours like VHSetaMax and CeeDeesLaserDiscs. Any recommendations or readings on Clustering both CPU's and Video Cards would be much appreciated. In the spirit of the TV Show Sister Wives, I'd love to make a spin off show called Sister Boards a reality... If this succeeds, I will embark on my follow up concept of creating an even more complex cluster (still in the concept phase) called a Mother-Grandma-Board!!!
