There's gold in the BOINC Client config parameter doc page. Problem solved! Again, thanks to all the folks who assisted me in digging this out! Got it! Following info. Shotgun approach that works. All parameters are documented at boinc site. All 3 GPUs run collatz while 3 rosetta tasks run! This works on my 6 core I7 and 8 core AMD, both eunning Win 10. URL for boinc configuration parameters: https://boinc.berkeley.edu/wiki/Client_configuration cc_config.xml in C:windowsprogramdataboinc Use all GPUs for collatz. Exclude NVIDIA GPUs for rosetta. I run NVIDIA only. Also arguments for other GPU types and GPU by number like 2 for second one? cc_config.xml ------------------------------------ <cc_config> <options> <use_all_gpus>1</use_all_gpus> <skip_cpu_benchmarks>1</skip_cpu_benchmarks> <exclude_gpu> <url>https://boinc.bakerlab.org/rosetta/</url> <type>NVIDIA</type> </exclude_gpu> </options> </cc_config> This app_config in C:windowsprogramdataboincproject...collatz... directory. Says to use a GPU for each collatz_sieve task. I personally don't want to try fractional values for <gpu_usage>, though you may be able too with 6GB or 8GB GPUs. Supposed to allow multiple tasks per card that way? app_ config.xml in collatz project directory --------------------- <app_config> <app> <name>collatz_sieve</name> <gpu_versions> <gpu_usage>1.0</gpu_usage> <cpu_usage>1.<span class="mark">3</span></cpu_usage> </gpu_versions> </app> </app_config> ** This app_config in C:windowsprogramdataboincproject...rosetta... directory. Says limit rosetta to N tasks, 3 here. app_ config.xml in rosetta project directory --------------------- <app_config> <app> <name>rosetta</name> </app> <project_max_concurrent>3</project_max_concurrent> </app_config> Crunch those numbers!

The app_config.xml for Collatz project did not solve the problem. I've found that reducing the % of cpus used in BAM preferences will reduce the number of rosetta tasks that run concurrently, from 5 at 90% to 2 at 40%. Unfortunately, that does not solve the GPU problem either. All 3 GPUs run Collatz tasks with rosetta suspended. When I click resume for rosetta, Collatz processing pauses momentarily in BAM display, then 2 of my GPUs go into wait mode and multiple rosetta tasks start.. I also set resource preference on rosetta page back to 100, since trying to limit rosetta resources that way doesn't work. I suppose I might find a clue in the backup files of one of my PCs before BAM and BOINC were reinstalled recently. Last week one PC was actually running 3 collatz GPU tasks and 3 rosetta tascks at the same time before I cleaned out old files to clear the error for 2 connections to rosetta. But when the rosetta tasks completed, rosetta went into pause and BAM told me the pause was at my request, though it wasn't? So clearly something was not right. Gonna keep trying to resolve this somehow. Thanks to the folks that gave me feedback on this.

In the past, was able to run Rosetta on those PCs with no issues. Ran all 3 GPUs and 3 rosetta tasks at a time. However recently, I was getting messages from Rosetta that I needed to detach from Rosetta@Home and reattach to URL https://boinc.bakerlab.org/rosetta/. Prior version of rosetta cross-connected somehow? Hadn't run rosetta since early spring. Couldn't resolve this until I deleted all references to Rosetta in my BOINC data directory. Re-added Rosetta in BOINC Manager. Now rosetta runs multiple tasks while only 1 of my GPU task can run at a time. I see many msgs asking for control of rosetta for similar resource issues. Sad that my PCs with 6 or 8 cores can not use 3 for GPUs and the rest for rosetta? Guess Rosetta is off the list for me if this can't be resolved. At the rosetta page, I actually set the project resource percent usage "preference" down to .001. This shows in BOINC manager, but sems to do nothing? I have 1 4-core processor machine with 1 GPU that I am running rosetta on, since no problem there. Solution needed in application configuration! Tired of mucking around with preferences all over with no results!
