I get the same on my RX560 under openSUSE Linux. It seems the Linux application part is buggy. I've opened a ticket on github where the code is hosted but no reply yet


Drivers are available and they can be installed but OpenCL part doesn't work well with BOINC.

Hello,

Here are my results

OS: Linux Mint 19 Tara
BOINC Version: 7.9.3
CPU: Intel i7-4770 @ 3.40GHz @ 2700MHz (HT on)

5 WU
avg run-time - 5,205.49s

I am going to post results for Intel i3-2100 @ 3.10GHz as well once Nbody WUs will finish.

Since I've never done N-body, I am not sure what the app name for it is. Likely just nbody.

The app name for the Milky Way N-body simulator is "milkyway_nbody". Hope this helps.

Thanks. Worked perfect.

Hello,

I would like to run one 'N-Body Simulation' and two 'Separation' tasks at once.
Would this configuration be correct?

<app_config>
   <app>
      <name>N-Body Simulation</name>
      <max_concurrent>1</max_concurrent>
      </app>
<app>
      <name>Separation</name>
      <max_concurrent>2</max_concurrent>
      </app>
</app_config>

>>> All the questions here have answers in other threads.

What you say there is possibly true, but if, as I, you are connected to many projects, reading all threads on all forums at all projects would take more than a day per day.

The solution for me, is to reduce the number of projects I support, the ones I drop first are the ones that "irritate".


No, if you have a question, spend 5min to read the couple of threads at any given forum instead of wasting someone else's time. No one's going to beg you to stay. And there was more than 1 question nor was my post directed solely at any one person. I didn't even quote you.


We should not forget that sometimes forums can be 'littered' with same questions asked multiple times in different way. This can be annoying for some people.

I agree with what you said about reading few posts. It doesn't hurt to try and find solution yourself in first place if there is one available.

Thanks for pointing it out, Marsinph. It was spelling error, that all.

No credit was awarded despite tasks were completed and validated.
