How much stress on a GPU

[NudgeyNR]

How hard does PG work / stress a GPU??

Do people run one wu per GPU or more ??

PG runs the CPU and GPU pretty hard.  In the preferences you can state weather you want to run multi-threaded where more than one CPU core is run per task, and they finish quicker and more chance of being the first to return if it is Prime Number.

I also give permission and give my name in the "Reporting primes to the Prime Pages" in the default preferences so I am credited with any primes I find.

I run 2 x wu's at a time on my cards. The Radeon VII's can handle it but it's barely worth running 2 on my Vega 56 & 280X.... I just can't be bothered changing the app config :)
Running 2 wu's on my Radeon VII still doesn't put the GPU under full load and it runs MUCH cooler than say running Milkyway or Einstein.

CPU is a different story. Quite hard on the temps although multi threading isn't used quite as much now with LLR2.

Have found plenty of info on how to setup PG CPU side of things, but nothing on how to run multiple wu's on a GPU.

Can i simply tell the project to run multiple wu's on every project with a simple change or do i have to setup for each project i choose to run ?

@chooka how have you gone about setting up the config file to run multiple wu's on your GPU's ?

I use this -

<app_config>
<app>
   <name>pps_sr2sieve</name>
   <report_results_immediately/>
   <fraction_done_exact/>
</app>
<app_version>
    <app_name>pps_sr2sieve</app_name>
    <plan_class>openclatiPPSsieve</plan_class>
    <avg_ncpus>0.0001</avg_ncpus>
    <ngpus>0.5</ngpus>
</app_version>

</app_config>

Happy crunching!

@chooka So i have to do those settings for every project i crunch on that particular GPU ?
