Hi Charlie Please look this message: http://setiweb.ssl.berkeley.edu/beta/forum_thread.php?id=2182&postid=52412
From it one can infer that BOINC detected both GPUs and both GPUs (ATi ones I mean) is active, use all GPUs switch enabled. Regarding platform warning - it means that app own enumeration scheme detected different platform than proposed by BOINC. Surely it will be cause BOINC API call resulted in error. Does -33 error code corresponds OpenCL specification? If so, it probably means BOINC API made OpenCL 1.1 call perhaps while device is OpenCL 1.0. Please check this possibility. Regarding using NV instead of ATi - hardly possible. App runs on ATi GPU after all (and exactly on HD4xxx GPU, device 1 by means of own enumeration scheme). wbr Mon, 15 Sep 2014 05:18:08 -0700 от Charlie Fenton <[email protected]>: >Hi Raistmer, > >boinc_get_opencl_ids() reported the reason for the failure in this line: >> Invalid OpenCL GPU index: 1 >This error will occur if the value of <gpu_opencl_dev_index> provided by the >init_data.xml file > >It would be very helpful to see the init_data.xml file to understand what went >wrong. > >Does user TBar have the following option set in his cc_config.xml file? >> <use_all_gpus>1</use_all_gpus> > >If not, then BOINC will normally use only the most powerful ATI GPU (the 6770 >Juniper), so the 4670 (RV730) will be ignored, so the highest valid OpenCL GPU >index will be 0.
