.. looks like it's not working. I've set it to 0.5, but Nevertheless, if this is working it's the biggest improvement here, I offer any help I can give to get this thing running. |

Update It works now for the nvidia wu's but not for the ati openCL. The problem was an app_info which was in the einstein directory, it affected the albert wu's as well. |

We were testing this feature here for usage on Einstein@Home. Honestly I don't have any idea how an OpenCL App or an ATI card would behave when running more than one task at once. BM |

Hi, since I do it sometimes at Milkyway, I can tell you, perfect behaviour! The project has changed his app to openCL some weeks ago. Now both (nVidia and AMD - apps) are openCL, both work fine running more than one task on a card. Give it a chance, I'll test it for you! Regards, Alexander edit: just to give an expression how this is done at MW, here is the app_ifo for that: <app_info> <app> <name>milkyway</name> </app> <file_info> <name>milkyway_separation_1.02_windows_x86_64__opencl_amd_ati.exe</name> <executable/> </file_info> <app_version> <app_name>milkyway</app_name> <version_num>102</version_num> <flops>1.0e11</flops> <avg_ncpus>0.05</avg_ncpus> <max_ncpus>1</max_ncpus> <plan_class>ati14ati</plan_class> <coproc> <type>ATI</type> <count>0.5</count> </coproc> <cmdline>--gpu-target-frequency 10 --gpu-disable-checkpointing</cmdline> <file_ref> <file_name>milkyway_separation_1.02_windows_x86_64__opencl_amd_ati.exe</file_name> <main_program/> </file_ref> </app_version> </app_info> |

I am trying to test it, but I cannot get any tasks for my OSX ATI machine.

ATI OpenCL Applications are currently only available for Windows and Linux. I think there is a serious problem with the OpenCL (1.1) App on Mac OS X, that will be fixed with Apple's next system update to Lion. BM |

Update: We see some improvements in the OSX support, but it's not quite sure yet whether it will be sufficient to be able to have a stable app for Lion or even Mountain Lion together with Linux and Windows. Probably teh OSX app will come later than those for Windows and Linux. Cheers HBE |

The first task which I am running before change to .05 is still showing 1.0 First task was started with setting GPU 1.0 Second task started with setting 0.5 But the other shows running 0.5GPU's I am running 2tasks simultaniously now. ATI 5850 CAT 12.3 BM 7.0.26 :) It uses Both my cores so I have no CPU% left for other tasks. Windows task manager says each task is using about 20% so if that could be modified to the app, that would be great. I think SETI Beta is now using some way of <flops> calculation to set the CPU % before tasks is started. |
