You won't need to run that command every time you edit a file, but it is worth doing it after you copy files from some other place to the BOINC working directory as sometimes the permissions don't get the directory permissions, but carry their "old" permissions along for the ride. I've noticed this most when using a USB stick to do the transfer....

. . I need to start a notebook and write down all these commands and syntaxes and stuff because I have a goldfish memory. But I think this time I really, really stuffed up.

. . IT'S WORKING!!

. . But of course Murphy is still looking over my shoulder, he is never far away, each work request is now being greeted by stoney silence :(

Run times seem OK. An ar .44 task that used to take 700 seconds goes now in 300 seconds.
Did you test offline with vlar work from Arecibo and GBT?

. . Hey there TBar,

. . I have to grovel a little. Your 1050 is only a mere few seconds behind my 1050ti. 305 for me and maybe 3010 for you, though it is early days yet that is a difference not work mentioning. I cannot do a screen grab of the nividia-smi -l display but:

Fan at 65%
Temp at 61degC
Power at 60/75
But
GPU use at only 90%

I think the memory management can keep up with the 1050 in full crunch but not quite with the 1050ti. So for Seti crunching with Your special app the 1050 is the better choice. Cheaper to buy and cheaper to run. Of course I am running an MSI low profile version with standard clocks, on an OC version like a Strix with an external PCI-e connector there might be a little bit more difference in results. But bang for your buck seems to go to the 1050. Though best bang for your Watts still seems to be the 750ti.

Stephen

I can vouch for truth in advertising;

https://www.newegg.com/Product/Product.aspx?Item=N82E16814487296

It's clocked to the Moon. It's running around 1800MHz, way above the claimed Boost Clock.

To copy the nvidia-smi window, go to the top menu and select Select All, then Copy
It updates every few seconds so you have to catch it between updates. When you paste it, delete all but the bottom reading and frame it in pre /pre

Nothing wrong with the 1050/ti's as far as I can tell. Once we work out how to fully leverage the compute capacity without setting peoples' houses on fire, then they might well be the optimal bang for buck goto cards. It's just a shame that the status quo dictates going for the premium over the majority. In the long run though I feel that most crunchers are based in reality, which means these things are pretty awesome.

. . Hi Michel,

. . As I learn more I am feeling less "lost in the wilderness", but my heart still likes to look out windows. I am going to buy a nice little book and write down all the things I have learnt so I can find them again when I need them.

. . Still not entirely comfortable with Linux but CUDA80 is definitely two thumbs up ... There is a bit of a problem however. Now that I have seen what it can do on a GTX1050/1050ti I have a growing compulsion to see what it can do on my GTX1060-6GB's in my poor old Pentium-D. So now it is going to cost me more money. I have to buy 2 new drives, one to make Linux permanent on this machine <Core2 Duo + GTX1050ti> and another to install it on the Pentium-D. I guess you can say I am hooked :)

<shrug>

If you were using the Berkeley version of BOINC in your Home folder you wouldn't be having these permission problems ;-)
That's why I use it, it's soooo much less annoying.
If you haven't done it yet, change the setting so the .xml files open with gedit. Right click on the .xml, select Properties, Open With - gedit. Set it as Default.
To visually edit cc_config.xml as Root, Open a terminal and enter gksu nautilus. Navigate to the file and open it with gedit. Make the edit and hit save.
You need to add the <options></options> tag to your existing file.
There is only One option, Zero disables it, One Enables it. It should Increase your GPU Usage by letting the App run at Nice level Zero.

. . Having seen how well CUDA80 performs on the 1050ti I will be making the change to Linux permanent, so I will be forking out for the cheapest SATA HDD available (1TB seems to be the minimum these days), and re-installing Linux on that. But Linux will then have a LOT of room to play in, and I will absolutely NOT be installing the repository version of BOINC.

. . It will mean losing the current host ID and creating a new one unless there is some way to migrate it from the USB drive to the new installation on the HDD, which I have not yet given up on doing. My theory is that if I run the cache dry, then install Linux to the HDD, but before re-installing BOINC copy the current active BOINC files onto the HDD /home where BOINC will be installed, then run the non-repository BOINC installer pointing it to that folder, it will recognise the exising host details and re-activate it.

If you haven't done it yet, change the setting so the .xml files open with gedit. Right click on the .xml, select Properties, Open With - gedit. Set it as Default.
To visually edit cc_config.xml as Root, Open a terminal and enter gksu nautilus. Navigate to the file and open it with gedit. Make the edit and hit save.
You need to add the <options></options> tag to your existing file.
There is only One option, Zero disables it, One Enables it. It should Increase your GPU Usage by letting the App run at Nice level Zero.

. . I've been doing that manually each time, right-click select gedit and open. Making it default will be much nicer :)

. . I was going to just cut/paste your options section into my file. But I guess I don't need all the settings. If it works then I guess I will be pumping up my fan settings even further :(.

Stephen

. . So should I be disabling it or enabling it? I have added the option using a value of 1 but there seems to be no difference. I selected 'read config files' to make sure it has read the file. Is there anything else I need to do?

Stephen

?

Are you sure it's working? If it's working you would see a message in the Event Log when you run the Read config files;

Mon Mar 13 11:01:18 2017 | | Config: run apps at regular priority

Since running at Regular Priority would mean running at Nice level Zero, open Top and see what the App has for a Nice (NI) value.
It's possible the Nice level doesn't matter that much with the Special App, it might even vary by machine and number of GPUs.

I think that is the difference of installing BOINC in the home folder or system folder. The Software Center automatically puts it in the system folder and makes priority changes difficult because of the user account' boinc'. This is my output with priority flag set or unset, it doesn't change.

. . BTW I have in my hot little hand a nice new 1TG HDD, it will replace the shaggy old 250GB in the Pentium machine and will house the new install of Linux. The two GTX1060-6GB cards are getting CUDA80! I figure the outrage is a perfect time when it runs out of work to suspend BOINC, take it down, disconnect the HDD and SSD and connect this in their place (I'll probably toss in the extra 4GB ram as well). A quick boot from the Ubuntu Install DVD and quick as a flash - Linux. I haven't taken notes yet but I will be referring back to the messages and it will hopefully have a reasonably painless rebirth as "La-Bamba" the Linux Guppi muncher. With the lower demand CUDA80 makes on the CPU and without the extended SoG load time it should turn out some impressive numbers (I hope).

. . I have the fever .....

. . Then tomorrow night ......... We'll take over the world Pinky ... ooh oops wrong thing.
