After reading many threads, i’ve decided to venture here and attempt to find a straight answer.
I am trying to use a Geforce GTX 570 purely as a CUDA device to run simulations.By now i’ve figured out:
- Windows 7 WDDDM feature resets my card if my kernel takes to long to execute
- You can change the "watchdog" timer in registry keys
- Geforce cards are not TCC capable.
- BIOS will not power on my card if i use integrated motherboard graphics and is unrecognizable in device manager
- Having two CUDA cards installed may or may not work.
My questions are:
- Should Kernels naturally be short processes? (i.e. loop kernel calls instead of one big kernel call that would take a few minutes)
- Why would Nvidia advertise their geforce cards as CUDA capable cards if theres no way to simulate for longer than 5 secs?
- If i indeed had two cards, how would you set it up to where WDDM wouldnt "watch" the CUDA card?
Answers would be greatly appreciated!
