Message 1973575 - Posted: 5 Jan 2019, 8:44:38 UTC - in response to Message 1973572.  

run_manager is just a script. To check all the apps 'ldd' these
boinc
boinccmd
boincmgr
boincscr
switcher
and maybe do the AP and MB apps to make sure.

Ah, I see, thanks.

You might as well trash 7.2.42, it won't work in anything higher than around 15.04, and will just cause confusion.
The version I gave you, 7.8.3, was compiled with Static libraries and usually works with everything from Ubuntu 12.04 to 18.04 needing just libwebkit in most cases.
I tried the new DL from C.A. on my 18.04 and it worked as expected. If you expand the file outside of your 18.04 system it will reset ALL the execute bits. You should copy the zip file to your system and then expand it to save the execute bit settings.

Looking at my notes I see ...

libpng12 For Ubuntu 18 - bonicmgr needs it
libpng12-0_1.2.54-1ubuntu1.1_amd64.deb

Also ... sudo apt-get install libcurl3 ... I don't recall seeing that in this thread, but could be for older OS

Just curious how I would know it should be lincurl3 not *2 or 4 ?

Message 1973607 - Posted: 5 Jan 2019, 13:15:37 UTC - in response to Message 1973606.  

From memory I seem to recall Keith finding something like a libcurl 34 patch for UB18 when he first installed it, so I'm guessing 4 is required for UB18.
I forget if png12 included it or not, but I am running BOINC 7.2.44 on UB18.

Because the only two ever needed are libwebkitgtk and libcurl3.
In most cases you only need the webkit, sometimes you need libcurl3.
Either run sudo apt-get install libcurl3 or open the Synaptic Package Manager and search for libcurl3, then install the package that way.

I really don't remember having to install libcurl3 in my version of 18.04.1. Did you install the 18.04 image or the 18.04.1 image? Also, did you run the Updates after installing?

(and updates ran in installation process)

Well, your answer based on pre-knowledge. If such pre-knowledge unavailable what proper way to solve DLL-dependence issues in Linux?

For example:
one uses ldd <executable> and sees that required DLL <XXX.so> missing.
One needs to install package, that contains that <XXX.so> file. But package could be named differently, for example <YYY>
So, how one should infer <YYY> from <XXX.so> ?
Or only almighty Google can help? That is, Linux completely unusable offline or w/o full power of search engine ???

EDIT: comparing to Windows it's general way to provide required dependencies WITH OWN installer. So, when installer works it installs all required to run particular program.
So, here is big difference between approaches to software installation between 2 OSes.

or use the Locutus of Borg ppa.

No-no-no, no borgs here, they are purged :)
Actually, label-names are good and handy when one already have some knowledge and seeks way to remember it and to ease recall of it.
W/o that such label-name is just void, unfortunately.
I suppose typing "sudo apt add-apt-repository ppa:Locutus of Borg" would fail so didn't try that.

It would have worked if you had added his name as owner to the ppa.

I just checked my only UB18 box with v4.2.44 which I recall having problems with getting/finding libcurl4 and I see libcurl is not even listed as a dependency now, I wonder if that PNG install fixed that?? I forget now.

The libpng12 is obsoleted from the 18.04 software sources. So if you need it you have to get it from older repositories. Shouldn't be needed on 18.04 anyway. 18.04 uses libpng16 and satisfies 7.4.44 and 7.8.3 just fine.

The only libraries needed are libcurl3 and libwebkitgtk-1.0. 18.04 comes with libcur4 and is not inclusive of libcurl3 so the default libcurl4 library does not satisfy the client.

Just use Synaptic Package Manager to search on libcurl and you will see both libcurl3 and libcurl4 listed. Install the libcurl3.

Distributions past 18.04 have dropped the libcurl3 and so another solution is needed.

There is a ppa called libcurl34 that includes both libcurl3 and libcurl4 in the same library and satisfies the client in later distributions.

I just checked my only UB18 box with v4.2.44 which I recall having problems with getting/finding libcurl4 and I see libcurl is not even listed as a dependency now, I wonder if that PNG install fixed that?? I forget now.

Shouldn't have. One has nothing to do with the other. The libpng library is just to deal with displaying the BOINC screen saver. The libcurl libraries are very important with server communications and are absolutely necessary for the client boinc.

I took a look at your completed tasks, Raistmer.
You could probably bring those runtimes down quite a bit by adding the -nobs command line option.

It looks like to me he is running 4 CPU tasks on his four core CPU and starving the GPU. If he just disabled one CPU by changing the 'On Multiprocessor systems use at most' to 99%, he would free a cpu and get much faster CPU & GPU times. My 1050Ti at BETA is running on a ten year old machine using a PCIe Gen1 x1 slot and completing Arecibo VLARS as fast as he is completing normal Arecibo tasks,
Mine - https://setiweb.ssl.berkeley.edu/beta/result.php?resultid=31881843
His -https://setiathome.berkeley.edu/result.php?resultid=7307221921

Definitely something wrong with his setup.
The Run-time is much longer than his CPU time meaning the CPU App is having to wait on the CPU to be free,
Run time 1 hours 19 min 38 sec
CPU time 1 hours 16 min 30 sec

Well, I want to establish default baseground then attempt optimizations.
Regarding CPU apps: only BOINC + default OS setup on that machine. 4 cores so 4 CPU apps. iGPU disabled (more precisely, initialization set to PEG instead of IGD).
So nothing should steal CPU from CPU app. GPU maybe starving indeed.
Please advise some tools like Windows's GPU-Z/CPU-Z for Linux.
For CPU usage I could use top command, what about GPU?

So, these are stealing CPU:

1 root 20 0 225464 9172 6676 S 0,0 0,1 0:01.56 systemd


Smth wrong with driver setup? 24 mins for IRQs seems a lot.

So, the plan is to take host offline for a moment then run in same mode for ~day (actually, until all tasks completed).
Then attempt to free one CPU core and repeat.

BTW, I already see good speedup versus Windows+SoG. So you say it can be improved even more?

You are running the CUDA9.0 version. Maybe it´s better if you try to run with: setiathome v8 enhanced x41p_V0.97b2, Cuda 9.20 special who was the latest avaliable for the CUDA 9 builds.

If you can´t find it PM and i will send it for you.

I have this one: "setiathome_x41p_V0.97b2_Linux-Pascal+_cuda92"

Will it run with 396 driver ?
