Well, I didn't think I would find another project that would be interesting. However I did, and now I have attached all my computers to WCG.
We do have a team there too, also called Seti Orphans, and we need more teammates.

Consider joining WCG, and maybe use my Unique Team Recruitment Link when you register:

Need more! :D

I don't understand why "waiting to run"?
There are 2 CPUs. But only one CPU task working.
How to decipher "waiting to run" into some hint how to run it?

https://clip2net.com/s/46YG8fH



2 threads

1 thread for Seti
2nd thread for Einstein (unlike Seti, Einstein will use up to and including a full thread depending on which work unit it is. It will also, sometimes use more than 100% of a thread or 110-155% of a thread)

That second Seti work unit is waiting for cycles on one of the 2 threads so it can run.



Ah, GPU app took whole CPU, I see. Missed that.

Please advise how to install OpenCL runtime on linux host?
(for NV and probably iGPU, if Linux could support them both )


sudo apt install ocl-icd-libopencl1

It worked, thanks!
Now GW NV app downloading.

I am gradually switching to Rosetta and have found this new thread very useful. I still wish to post on the "Ryzen and Threadripper" thread but if you don't read that I just chuck into the pot the info that my 2990wx with 32gb is crunching 60 threads with only an occasional one showing "waiting for memory" for a time - but it clears. Thus they can't be taking 1GB of memory at present.

if you're talking about the GW nvidia GPU app, yes it can use more than 1 core, that app requires a lot of CPU support to feed the GPU. I noticed this on a few systems. it tries to pull >100% of a thread, making it spill over into a second thread. will happen more on a slow CPU.

No, it's CPU app. NV GPU still idle :(
No Linux GPU app??


there are linux nvidia (and AMD/ATI) GPU app available for both GW and GRP. you have to select them in your preferences on the website.

edit, if you're talking about your 1050ti system. you don't appear to have openCL drivers installed. the Einstein apps are openCL, not CUDA

AFAIK if task can't run it will say that in its status. Waiting for memory or smth alike...
Usually, yep.
Ian&Steve's post looks like it explains it- the other project using the CPU resources at the time. As you suggested- Scheduling.

Rosetta tasks now crunching too (3 of them), but almost hour passed....
The default runtime is 8 hours.


Why did they wait so long (in ready to start !) ??
Memory or HDD space limitations?
Current Tasks don't use much, 250-500MB RAM, 610MB HDD space) but there are plenty of Tasks that will need 1.3GB RAM, 1GB HDD space.

Message 2044310 - Posted: 11 Apr 2020, 23:08:12 UTC

Funny that I've always had to use an app_config.xml with Rosetta or it would rob cores needed for GPU work by Einstein (and I needed the heat off those GPU's during cooler times of the year, like now).

<app_config>
 <project_max_concurrent>N</project_max_concurrent>
</app_config>

N=2 in my case with rigs that have 4 core CPU's with dual Nvidia GPU's.

Cheers.

Strange thing - Einstein runs GW app, sinle task ( CPU has 4 corers), few Rosetta tasks in "ready to start"state but not running. Is GW app multi-CPU one??

Got answer on it already - no, not multithreaded. Rosetta tasks now crunching too (3 of them), but almost hour passed....

Some issue in BOINC scheduling it seems %)

Added Einstein and Rosetta on Linux host with NV GPU recently.

Strange thing - Einstein runs GW app, sinle task ( CPU has 4 corers), few Rosetta tasks in "ready to start"state but not running. Is GW app multi-CPU one??

And can E@h use NV GPU under Linux? 1050Ti ran CUDA special before, now idle.... Or should I find third project or chage OS on that host?...


BTW, happy Cosmonautics day to all!!!! 12 April here already!!

did we overload Rosetta, or does it have a regular maintenance on Saturday's??

edit: nevermind, it looks up again.
