I know on some projects an app_info.xml file helps to run two units at once and other tweaks, would it be helpful here. I have two Nvidia 560Ti gpu's and each is a 1gb card using only 399mb per workunit, that should leave enough headroom to run two units at once? The card is also using only 78% "gpu load" when crunching. The fan is at 54%. All of this is according to gpu-z ver 6.6, the newest.

you will have some tasks with low gpu utilization and running 2 at once MAY increase total throughput.

however there are several tasks that can utilize up to 99% utilization already and I would guess running 2 at once would be very inefficient.

Why don't you try and tell us what you find?

Thanks for the response but I do NOT have the ability to make one that will work, I tried once, on another project, and it failed miserably. I can crunch but no longer program, that was a skill I had waaaay too long ago.

Also I was running the ACEMD2 tasks when I asked and am now running the Nathan or Long Run tasks. The Nathan tasks are using 969mb of the cards 1gb of memory and has a 91% gpu load. This means an app_info file for this type of file won't work for me.
