Yea my stderr looks the same as yours, but regardless of what it says the 2 WU's only run on just one of the GPU's. Tomorrow I'll do some more fiddling and try that test you mentioned too. But for now it's time to hit the hay, it's 2.45am here in the great land down under.

This is the host in question. hostid=150749 I'm not sure of how much value it will be as all the latest results will show all the WU running on d 0, thats because i've now reverted back to using d 1 with another project until a fix is found.

Thanks again


PS: Does anyone else have 2 or more of the same Nvidia GPU's crunching correctly?
IE: By correctly I mean each GPU being used should be under load. Check using GPU monitoring apps like MSI afterburner, GPU-z, Nvidia inspector, ect.

Latest version brought back the 3 second computational errors again:

This version WORKS for me. THX very much for solve this problem! Will be there some patch to how to work on more that 1 GPU simultaneously directly from BOINC wo any non standard steps?

It should work already, if it does not I'd like to see stderr output from a BOINC client running the app on two or more GPUs.
Just let it run more than one task for a while, then you can abort them.

Both ran on GPU 0

Later i'll try a reset to see if downloading fresh apps makes any difference.

According to stderr, wrapper correctly sets -d to 0 or 1.

wrapper [26118 765 +dev#]: starting (GPU #1)
19:49:20 (13592): wrapper: running enigma_cuda.exe (-d 1 -R -o results.txt 04trigr.cur 04unigr.cur 04ciphertext)
20:12:22 (13592): called boinc_finish

wrapper [26118 765 +dev#]: starting (GPU #0)
19:48:32 (10808): wrapper: running enigma_cuda.exe (-d 0 -R -o results.txt 04trigr.cur 04unigr.cur 04ciphertext)
20:11:38 (10808): called boinc_finish

Could you try .bat files from this zip package ?
https://s3.eu-central-1.amazonaws.com/enigma4/test_runs/multigpu.zip

I suspect that the app somehow ignores -d option, as it runs with -d 1 on my single GPU system.

On my system with one GPU, if started with -d 1, the program returns "GPU 1 not found. Terminating."

I think it ignores -d combined with -R.

this stops with GPU not found:
enigma-cuda -d 1 -M M3 -n 30 -a -f B:423:AA:AAA -t B:423:ZZ:ZZZ -g 023 00trigr.86v1 00bigr.86v1 fhpqx100

but this runs on GPU #0 even if #1 is specified:
enigma-cuda -d 1 -R -o results.txt 00trigr.41v1 00unigr.41v1 fhpqx100

Right, the code was clearing all settings before reading the Resume file. Fixed now, other command line options included with -R now also work. Please download the exe's.

Message 5875 - Posted: 17 Jul 2017, 14:27:35 UTC - in response to Message 5874.  

On mine when I run "device_0.bat" it runs as it should do on d 0
When I then try to run "device_1.bat" nothing happens. Output = DONE: 0 passes in 00:00:00

The only way to get either bat file to run again is to unpack the zip file to a fresh directory.

After unpacking to a fresh directory and then running "device_1.bat" it does run but only on d 0 (not d 1)

Abort all the tasks assigned to app version 1.08 and try with the 1.09 that was just released.

BINGO!!!!!! Well done fella's it's fixed :)

Both your efforts are very much appreciated. Cheers.....



EDIT: The estimate has blown out a tad from 10.5mins to 2hrs 50 min but aside from that small matter all seems well.

Good news!! As an unexpected side effect of the new settings my pair of GTX 580's have started crunching too!!!

How fast? Now that's another matter entirely, but it's still good news for those with older cards :)

I'll post a link as soon as one finishes.

EDIT: 26mins not bad for a card of it's age. *Link to WU*

Good to hear Dzordzik, those 1080ti's will chew through WU's like there's no tomorrow. Your numbers should shoot up like a rocket now.

Yeah I crunched away on my tablet, which actually had pretty good RAC for a tablet, to get to 500k and a badge level. I saw the future news about a GPU app and waited for it as I knew it would blow away all previous work. 3 more days and I'll be at 10mil.

Are there issues with work distribution? I haven't gotten any new wu's since this morning.
