Can you run CPUs and GPUs simultaneously? If so, I assume you need to modify (merge) the 2 different app_info.xml files together. How is this done? I want to run both the .19f optimized GPU and SSE4.1 optimized CPU app. Bryan |

Basically no, you can't run optimized CPUs and GPUs simultaneously, not in the same BOINC manager. But you can run optimized GPU and then have a VM (virtual machine, eg, VMware Workstation) running another BOINC manager for the CPU app. Alternatively you can wait for the developing CUDA project http://milkyway.cs.rpi.edu/milkyway_gpu/ which I understand will allow you to run ATI gpu (as well as CUDA gpu) and CPU as seperate projects in the same BOINC manager. |

The only way you could merge them is if they sent out ATI specific WUs. Much in the same way at Seti you have Normal/Normal(cuda)/Astropulse/Astropulse(cuda), because you can distinguish between these apps you can merge and much around with app_info.xml files. As in MW there is no distinction, you cant. As Ice says, you have to VM or wait. Incidentally Ice, my VMs only show 1 proc per VM, meaning to use 7 cores I need 7 VMs. You found a way around this? I'm using the VM manager thing that BOINC suggests when setting up your own project (which I failed at doing....) |

However, when I configure the two processors it throttles the GPU processing and effectively stops the GPU crunching. I therefore have just one processor configured in VM and have just the one WU crunching there. |
