yes,
this file (the one I just added and fixed the "problem")

<app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>0.49</cpu_usage>
</gpu_versions>
</app>
</app_config>

is :
BoincData\projects\milkyway.cs.rpi.edu_milkyway\app_config.xml:

and this file

<cc_config>
<options>
<ncpus>0</ncpus>
<use_all_gpus>1</use_all_gpus>
<ignore_cuda_dev>11</ignore_cuda_dev>
<ignore_cuda_dev>12</ignore_cuda_dev>
<max_file_xfers_per_project>8</max_file_xfers_per_project>
<save_stats_days>360</save_stats_days>
<http_transfer_timeout>120</http_transfer_timeout>
<max_tasks_reported>50</max_tasks_reported>
</options>
</cc_config>
is

BoincData\cc_config.xml
( I no longer have the

"<report_results_immediately>1</report_results_immediately>"

line in it (every 90 sec's seemed a bit too often)

Great we now have work again!!

Well I had time to look through my archives of playing with BOINC and came across an old friend that worked here.

This is the ONLY change I made:

added BoincData\projects\milkyway.cs.rpi.edu_milkyway\app_config.xml:

<app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>0.49</cpu_usage>
</gpu_versions>
</app>
</app_config>

Read config files
and presto-changeo I now have both GPU's running!!


Thanks for the ideas!!

I believe that was SETI@HOME's solution (64 bit INT).. (The joys of success!!)

Just for fun, I think I'll turn MW@H on on a 1070 only computer and see if it is recognized and runs...

(if it gives me problems I'll trim cc_config.xml down a bit and see if that helps)

Ideas are welcome :-)

Windows 10 schedules a task in cpu pairs like I indicated (0:1, 2:3, 4:5 etc) and Ubuntu schedules in pairs of 0:12, 1:13, 2:14 etc. if it can ... I ASSUME this reduces context switching and thus reduces overhead.

I am not doing anything funky at this point ... running BOINC "out-of-the-box" ... I do have the old cc_config from SETI.

I continue to be puzzled by BOINC only scheduling 1 GPU for MW@H but scheduling both for other projects I've tried. I think it interesting that it runs 1 GPU task but downloads 2 pending even though i have a resource share set to "0".

Still open to ideas!!

Yes, BOINC sees both cards..

I have 11 CPU busy running WCG@H 1 CPU running MW@H and 12 "CPU's" idle. windows-10 is doing a good job of keeping CPU "pairs" (0:1, 2:3, 4:5, etc) at 100% and not mis-scheduling / overusing any one cpu.

Post:
Why do you have the ignore cuda device in your cc_config? And the device numbers are WAY outside your actual count.


That is a leftover from the SETI days when I was doing funky configurations :-)

BOINC picks up both cards in your host. BOINC only reports the most capable card which is the 1660


That doesn't answer the question of why MW@H only uses 1 GPU. SETI used both and GPU@H uses both (when it's up).

just joined the project with windows 10 on an amd ryzen threadripper 1920x 12-core 3.50 Ghz

I have a cc_config.xml in place under BoincData as follows:
<cc_config>
<options>
<ncpus>0</ncpus>
<use_all_gpus>1</use_all_gpus>
<ignore_cuda_dev>11</ignore_cuda_dev>
<ignore_cuda_dev>12</ignore_cuda_dev>
<max_file_xfers_per_project>8</max_file_xfers_per_project>
<save_stats_days>360</save_stats_days>
<http_transfer_timeout>120</http_transfer_timeout>
<max_tasks_reported>50</max_tasks_reported>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>


and have 2 GPU's as follows:
nvidia geforce gtx 1660 super (device 0) and
nvidia geforce gtx 1070 (device 1)

and only the 1660 super runs the project

any easy fixes??

P.S. also running WCG Covid WU's on the CPU's
