CPU and GPU client at same time, shutdown after both finish

(Wasn't sure which forum to post this in, so I posted it here. Sorry if this was not the best choice.)

OS is Windows XP 32bit. CPU is Athlon 64 X2 Dual Core 5200+. GPU is GeForce 9600GT. I'm already running the special GeForce viewer GPU client here.

This is what I want to accomplish:
- Run the CPU and the GPU clients at the same time.
- Configure both to pause after completing current unit.
- Automatically shut down the system after both clients are done and have uploaded their results.

First off, is it even possible to run both CPU and GPU clients at once? I will try it anyway, I just want to make sure there are no problems with that.

Second, what would be the best method to achieve automatic system shutdown after both clients are done?
I guess I could install Cygwin, write a bash script or something to monitor the logs of both clients and run a command when a certain string is detected in both logs. But it feels kind of hack-ish. I was wondering if there's a better way to do it.

It's certainly possible to run multiple clients ... including a CPU and a GPU client. The general recommendations are to run no more than one CPU client per CPU, but the GPU client is sort of an exception since it uses a small fraction of a CPU.

If your GPU is from NVidia, it already uses very little CPU. If your GPU is from ATI, you'll need to work with the Environment Variables to minimize the CPU utilization.
