I have 2 GPUs in this machine. First one is RX560, second is R9 280X. The RX560 began playing up (computing on it causes the display to flicker), so I can either use it as a computing card or a display card, and since I have 5 monitors on this machine, I've demoted it to display only, so: I inserted this: <ignore_ati_dev>0</ignore_ati_dev> into cc_config.xml and all was fine. MW ran on ATI 1, the R9 280X. But now I'm running SRBase, I heard the fan not making any noise and checked in MSI Afterburner, which confirms the wrong card is being used. I double cheright because of which one heats up. Boinc is still saying at startup: 16-03-2022 05:10 PM OpenCL: AMD/ATI GPU 0 (ignored by config): Radeon RX 560 Series (driver version 3240.6, device version OpenCL 2.0 AMD-APP (3240.6), 4096MB, 4096MB available, 2197 GFLOPS peak) 16-03-2022 05:10 PM OpenCL: AMD/ATI GPU 1: AMD Radeon R9 200 Series (driver version 3240.6, device version OpenCL 1.2 AMD-APP (3240.6), 3072MB, 3072MB available, 4178 GFLOPS peak) But it disobeys itself and uses only the RX560 (AMD/ATI GPU 0). I tried changing it to <ignore_ati_dev>1</ignore_ati_dev> and restarting Boinc, then back to <ignore_ati_dev>0</ignore_ati_dev> and restarting Boinc, but whichever one I set (which it shows in the event log correctly), it always runs SRBase on device 0 incorrectly. Switching back to Milkyway uses the correct card! In fact, Milkyway Collatz Einstein Primegrid Amicable Numbers all use the correct card. Why would one project be able to disobey Boinc's instruction? If I let it use both cards, SRBase uses both cards, but the one on the 280X doesn't get anywhere. Presumably it's incompatible with the 280X, and disobeys my instruction, but if they're both allowed, it tries both anyway?! Also posted in https://boinc.berkeley.edu/dev/forum_thread.php?id=14603

I have 2 GPUs in this machine. First one is RX560, second is R9 280X.

The RX560 began playing up (computing on it causes the display to flicker), so I can either use it as a computing card or a display card, and since I have 5 monitors on this machine, I've demoted it to display only, so:

I inserted this: <ignore_ati_dev>0</ignore_ati_dev> into cc_config.xml and all was fine. MW ran on ATI 1, the R9 280X. But now I'm running SRBase, I heard the fan not making any noise and checked in MSI Afterburner, which confirms the wrong card is being used. I double cheright because of which one heats up. Boinc is still saying at startup:

16-03-2022 05:10 PM OpenCL: AMD/ATI GPU 0 (ignored by config): Radeon RX 560 Series (driver version 3240.6, device version OpenCL 2.0 AMD-APP (3240.6), 4096MB, 4096MB available, 2197 GFLOPS peak) 16-03-2022 05:10 PM OpenCL: AMD/ATI GPU 1: AMD Radeon R9 200 Series (driver version 3240.6, device version OpenCL 1.2 AMD-APP (3240.6), 3072MB, 3072MB available, 4178 GFLOPS peak)

But it disobeys itself and uses only the RX560 (AMD/ATI GPU 0).

I tried changing it to <ignore_ati_dev>1</ignore_ati_dev> and restarting Boinc, then back to <ignore_ati_dev>0</ignore_ati_dev> and restarting Boinc, but whichever one I set (which it shows in the event log correctly), it always runs SRBase on device 0 incorrectly.

Switching back to Milkyway uses the correct card! In fact,
Milkyway
Collatz
Einstein
Primegrid
Amicable Numbers
all use the correct card. Why would one project be able to disobey Boinc's instruction?

If I let it use both cards, SRBase uses both cards, but the one on the 280X doesn't get anywhere. Presumably it's incompatible with the 280X, and disobeys my instruction, but if they're both allowed, it tries both anyway?!

The GPU apps can only run on device 0, it was not designed for multi-GPU.

not possible, its a BOINC wrapper issue
