Message 6054 - Posted: 19 Mar 2023, 8:39:19 UTC

Hi all,
I'm returning to Universe@Home and was wondering if there's any preference with which version or VM or Ubuntu runs best?

I'm a Windows user so I use a VM to crunch U@H however the times look pretty long for the VM. It's been a long while since I crunched, so I don't know if the credit amount changed or if I'm running and crappier version of Ubuntu or Oracle VM.? Currently using 5.2.44 & Ubuntu 18.04.6 & 20.04.5

Pretty atrocious credit by the looks atm.

I thought someone might know a combo that works well for them. Other VM users have any advice?

The amount of Credit per Task is fixed.
Linux gives better processing times than Windows.

Instead of mucking around with VMs you could just make use of Windows Subsystem for LINUX?

I use Win10 and orcal VB with Linux Mint Mate 20.x. It works very fine. Xfce would be enough, too, i think.
I´m sure, Mint 21.x would be a good choice, too.
Important is to have is the GLIBC library 2.31 or newer. Older versions are slower with universe (~50%). I guess Mint 20.2 and newer use the GLIBC library 2.31.

Thanks!
All but one of my systems currently has GLIBC 2.31. I'll try to upgrade the system that doesn't have it and see if there's any difference.

Ryzen 5950x running a VM & Ubuntu 20.04.6 Ubuntu GLIBC 2.31-0ubuntu9.9 the run times are ranging from 2,133.50 sec out to 8,752.44 sec.
Is that normal to have such a large variation in run times? or is it the VM/Ubuntu combo?

I know that native wins hands down. I'm trying to stick with the VM.

My i3 8300 has a rang from 1300sec to 3500sec. "Normal" for a 5950X, you can see her:

https://wuprop.boinc-af.org/results/graph_duree.py?projet=wanless2&application=Random-base%20WEP%20Factorization&plateforme=all&cpuid=39

But it depends of how many WUs are running and how good and fast your system is.

This might be useful for you, in case you forgot these threads existed.
It's still running perfectly, upgraded to a 5900x, with 20 threads active, serving 5 different projects.

Continuation (kind of) with updates after my upgrade:

Thank you!
So it seems I have everything correct running version 20 of Ubuntu. Still getting some shocking times though.
I currently have 2 wu's which have been running for 6.5hrs which seems odd. I'm running BOINC at 95% with no GPU work running. Generally it looks like 2hrs/wu on the 3950X :(

How hot is your CPU? If you running many WUs, the temperature is maybe high. Thus, the clock is reduced and the calculation time is longer.The traffic on the bus is then also high, with so many cores calculating at the same time. That slows everything down a bit. But hey, the output is still enormous!

Abot 87 degrees. Running at 3.91Ghz which seems pretty good.

I have 2x 3900x
One @3600MHz
Second @ 3200MHz (electricity bills and noise :)
Times are between 2500 - 5500. They are unhidden so You may check.
I suspect RAM is to slow in Your case to feed 32 threads.

Thank you.

"They are unhidden so You may check." Haha yes.... nothing spells "wanker" more than people who hide their hardware :)
I'll never be one of those elite tossers.

Not much difference in run times. It seems to be going ok now although..... the 3950X is lagging behind my other systems. Can anyone tell me how to update Ubuntu from 18.04.6 LTS to say
20.04.6 LTS?
I've tried sudo apt update & sudo apt upgrade but that didn't work. I'm hoping the pop up box will open at some stage advising me there's a newer version to update to but that's not happening. There must be a way to update from one build to another without installing Ubuntu all over again.

Open the Software&Updates application and open the Updates tab and make sure you have the "Notify me of a new Ubuntu version" toggled to "For long-term support versions"

Do a sudo apt update and you should be offered the dialog for updating to the Ubuntu 20.04.06 LTS version.

If not, then follow these instructions from this web page. https://www.cyberciti.biz/faq/upgrade-ubuntu-18-04-to-20-04-lts-using-command-line/

I have followed that page when I updated my Ubuntu - all went more or less OK. It's dedicated cruncher so I didn't pay attention for anything more than BOINC, GPU and temp reading.
