Hello,

mini_collatz v4.07 (opencl_ati_100) makes errors

mini_collatz v2.09 (ati13ati) work fine


why there are two applications for mini_collatz?

Please give an option to turn off the application v4.07



BOINC client version 7.0.64 for windows_x86_64


CAL: ATI GPU 0: AMD Radeon HD 6790/6850/6870 series (Barts) (CAL version 1.4.1741, 2048MB, 2015MB available, 2976 GFLOPS peak)

OpenCL: AMD/ATI GPU 0: AMD Radeon HD 6790/6850/6870 series (Barts) (driver version 1084.4 (VM), device version OpenCL 1.2 AMD-APP (1084.4), 2048MB, 2015MB available, 2976 GFLOPS peak)

ati13ati = Brook+/CAL app for HD6xxx and earlier GPUs
opencl_ati_100 = OpenCL for HD7xxx and later GPUs

Errors occur with the OpenCL application because AMD's OpenCL compiler is broken in certain cases. AMD engineers are working on it. My guess is we won't see a fix for 3-6 months.

The server isn't supposed to send OpenCL work to HD6xxx or earlier GPUs, but the upgrade to fix the Intel GPU problem broke the logic I had put in for the OpenCL issue. Or rather, it wiped it out which means I have to go back and change the BOINC source so that it passes the appid to the sched_customize functions before it will work again.
