I guess it may be the universe telling me it's time to build the Ryzen rig I have been contemplating.

An R5 1600X is looking be the best bang for your $ in my books ATM. ;-)

Cheers.


. . I was thinking along the lines of the R7-1700 but an r5-1600 is not bad value either.

. . For now I have to put La-Bamba back together and see if there is a way to get rid of the cache it has on board. I wouldn't want to leave a couple of hundred WUs in limbo. Sadly it locks up so quickly now I am not sure I can do much with it, maybe if I suspend the network and see if it will crunch them all .. then with no crunching happening see if it can manage the final upload ....

After much hesitation and trepidation I finally bit the bullet and replaced Windows 10 with Linux on my main cruncher.
I also moved from SOG to petri33's CUDA80 "special sauce" version.

The results are outstanding. My RAC has gone from 18,000 to about 40,000 per day. Not bad for a slow 11 year old PC with a GTX 1060!

I’m drawing a total of 170 watts. The machine is: https://setiathome.berkeley.edu/show_host_detail.php?hostid=8296642

Below are the steps I took. It was a LOT simpler than I thought it would be. I was up and running in about two hours and I never installed Linux before.
I tried to write down all the steps but I might have missed something. Hopefully this can help somebody else out there.

I thought Linux was difficult to setup. It’s really not that bad. Mint 18.2 makes it pretty simple.

I’m now convinced we need a Windows’s version of petri33's version more than ever. A lot of people will not want to switch to Linux. A Windows’s version would be a huge benefit to the project as it would unlock the full potential of the NVIDIA hardware.

Cheers
Mark

----------------------------------
-- How I installed Mint 18.2
----------------------------------

Download "Cinnamon" Mint from https://linuxmint.com/download.php
Filename: linuxmint-18.2-cinnamon-64bit.iso

Download utility to create a bootable USB drive: https://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/
Filename: Universal-USB-Installer-1.9.7.8.exe
Select "Linux Mint" and then enter the path to linuxmint-18.2-cinnamon-64bit.iso

I installed an empty 250GB hard drive into the PC.
Place the USB into computer and boot. Pressed F12 for boot menu. Selected USB

Picked the first option on the Linux boot menu.
A GUI is then displayed.
Clicked Install Linux Mint
It will prompt you setup a user name / password

When Linux is running choose "Driver" from the "start menu".
Linux found my NVIDIA card and installed the driver with a single click and a reboot.

To install BOINC:
open a command prompt and enter:
sudo apt-get install boinc-client boinc-manager

Setup SETI as normal. At this point it should be running using the CPU.

Now, to setup the petri33's "special sauce" version.

Shut down BOINC.

Download these files:
Linux_zi3v-CUDA80_Special http://www.arkayn.us/forum/index.php?topic=197.msg4499#msg4499\
libcudart.so.8.0 https://drive.google.com/open?id=0B9PYeBxtfMjaZXlXNjcydU05eW8
libcufft.so.8.0 https://drive.google.com/open?id=0B9PYeBxtfMjaWC14YTNxRThCUWc

copy the files to /var/lib/boinc-client/projects/setiathome.berkeley.edu

Note: You might need root access to copy the files. If so enter.
sudo su

You will need to change the owner of the files just copied.
chown boinc:boinc *

Start up BOINC and enjoy.

Shut up. It's honestly that easy? :-O

No significant command line commando theatrics, no having to config it like all the tweaks I am learning about (again) in the SOG Windows app? Just pretty much follow your above list, and it is installed, up and running, and then its pretty much setup and forget for the most part?

Sure is, the combination of command lines you can count on one hand, and works great for mismatched GPUs.
Just think of how many more GPUs you can buy when you sell all those Windows licences :D

So simple it is unbelievable, the best is "autotune", which does what it should, looks at the cards and works out the best setting of "unroll" - I've tested it against a GTX1080 paired with a GTX780, GTX1080 paired with a GTX960, GTX1080 paired with GTX980 and it "got it right" in each case. Although now I've settled on homogeneous sets of GPUs I could probably set the "unroll" for each GPU type. My current Linux farm has three GTX1080, and pairs of GTX960 & GTX980 in three separate crunchers.

The command line I've settled on for all three of my Linux crunchers is:
-unroll autotune


As you say, so much simpler than the convoluted SoG command lines which go on for ever, are so easy to get wrong and screw the performance of your system.

I'm pretty sure Petri's app runs as a single CUDA task, but how much CPU support is needed for each task? Is it just as efficient with CPU usage as the familiar CUDA50 app?

It's been so long since I ran with block sync. If I recall it would use 10-15% with it on, 100% if off. Block sync can be looked at similar to -usesleep

I dedicate a full core, since my math says if I gain 1 GPU task / 2 hours that the CPU takes - it is well worth it!

You can compare the times of my host 8289033, which is currently running the x41p_zi3v app with Blocking Sync, versus host 8253697, which is currently running the zi3t2b app without Blocking Sync. I will probably turn off Blocking Sync on 8289033 at some point, as I think the overall throughput is much better without it, even at the expense of a dedicated CPU core for each GPU task and a modest increase in power use.

Petri's app is designed so that a single instance uses as much of the GPU as is possible, running two-per (even on a GTX1080) kills the performance.

. . Hi Keith

. . With 'bs' on it is as efficient with CPU use as earlier versions. If you want to push things add -nobs to your command line and make sure you have ample free CPU cores (at least 1 per GPU +1). It will tend to use slightly more (aint it funny) than 1 CPU core per GPU with 'bs' off. It is very similar to using SoG with 'sleep' on or off. And you get your best efficiency running just one task per GPU. TBar is trying to come with a version of BOINC that will allow you to run the later versions of Linux as these guys are suggesting while still instaling BOINC into a single folder structure in your home directory. At the moment using the later versions as these guys are doing will put your BOINC under the root directory and under ROOT control in at least 2 different locations, /var/lib/boinc-client and /etc/boinc-client which makes it a little more difficult to control/tweak. But CUDA80 has basically just those two tweak options anyway.

Thanks for the info guys. If I finally get around to installing Linux either in one of my existing crunchers or one I should be building out of spare parts, I will probably be running the -nobs command parameter then as I should have plenty of CPU cores to spare.

. . Hi Keith,

. . If you are building from the spare parts bin remember one very important thing! Special sauce requires an Nvidia GPU with CC of at least 3.2, preferable higher, and preferably with 2GB VRAM or higher. This rules out everything before the 7xx series and even many of those. I may get around to trying it on my GT730 (CC=3.5, Cu=2, Vram =2GB GDDR5) just to see how it flies. That is, if I can find a cure for what is ailing my Pentium-D.

Thanks for the reminder Stephen. Shouldn't be a problem as I have four spare 970s sitting on the shelf gathering dust. Probably will only install 2 because of PCIe spacing considerations. One of the reasons why I went with the new 1060 shorty card other than the power consumption advantage. I just have to decide to reuse an old case that doesn't fit the AIO without a kludge solution ... or buy another new case that fits the AIO properly.

... without a kludge solution ...
What? Kludging is fun :D

I got an Intel S5520HC board off eBay w/Dual 5530 CPUs and ram for $200 CAD, so what the heck could I lose? When I opened the box I thought to myself ... hmm, I don't remember if it said ATX or not ... LOL. It's an SSI EEB (12" X 13") board. So out come the tin snips and a variety of other tools, and a can of black paint, and poof ... It's in a former Athlon 1800 case that has been collecting dust.

The bugger I had was that the CPU back plate is part of the CPU holder, so the 1366 backplates wont work. And screws are way too short to connect to this backplate. I managed to scroung up enough M3 screws to make it work, but still not right - and a pain to install. But it runs at 59C with 2 130W coolers on 80W CPUs.

I just have to finish the front off to incorporate at least 2x120mm fans ... the case is designed for 3x80mm MAX :(

I'm surprised how good those E5530s work, quite comparable to my i5 (need to let the stats level out to see), it replaced my AMD 4200 .... finally retired!

EDIT: Or as Al would say ... I'm gonna need a bigger piece of wood :))

Well I decided to get off the pot. Just purchased a "scratch and dent" version of the Air 740 case I purchased for the Ryzen system and used up the credit I had accumulated on the cash back Amazon Prime CC. Got the price down to $50 and change. Will have to pull a ethernet hardline into the location but I have everything else ready to install. The case will make for an easy install of the 2 times RMA'd H100i I have waiting on the shelf. The FX-8300 gets used again in the M5A99FX motherboard and after looking at it again realized it will easily support 3 of the 970s. The USB 3.0 connector is in a out of the way place on the mobo and the PCIe spacings will allow full slot breathing room for each 970. Just downloaded all the files listed in this thread. I discovered an old 120 GB 2.5" spinner hard drive liberated from an old laptop on the shelf to use as the install drive. I thought I was going to have to use a IBM 80GB SSD that I use for my astroimaging but the Toshiba drive will work nicely.

Case should be here Wednesday. I would think I should have the system up and running by next weekend barring any unforeseen obstacles. Will ask for help if needed from the experienced "special sauce" users.

It's easiest to just burn the ISO to a DVD if you have something that is portable/moveable, then you can use that old HD for the OS. 120GB is tons of room, I'm still running on an 80G IDE drive :) <<EDIT: I meant 20GB>>

First hint/advice .... Linux is very picky with security when changing passwords (Cap, small, numbers, characters .... blahh) BUT it is very lenient during the install, so chose well :D .... And set 'auto login'

Apps: PSensor, GKRelIM from the software manager. 'sensors-detect' in the terminal, may find other sensors that are not 'standard'

-- How I installed Mint 18.2
----------------------------------

Download "Cinnamon" Mint from https://linuxmint.com/download.php
Filename: linuxmint-18.2-cinnamon-64bit.iso

Download utility to create a bootable USB drive: https://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/
Filename: Universal-USB-Installer-1.9.7.8.exe
Select "Linux Mint" and then enter the path to linuxmint-18.2-cinnamon-64bit.iso

I installed an empty 250GB hard drive into the PC.
Place the USB into computer and boot. Pressed F12 for boot menu. Selected USB

Picked the first option on the Linux boot menu.
A GUI is then displayed.
Clicked Install Linux Mint
It will prompt you setup a user name / password

When Linux is running choose "Driver" from the "start menu".
Linux found my NVIDIA card and installed the driver with a single click and a reboot.

To install BOINC:
open a command prompt and enter:
sudo apt-get install boinc-client boinc-manager

Setup SETI as normal. At this point it should be running using the CPU.

Now, to setup the petri33's "special sauce" version.

Shut down BOINC.

Download these files:

copy the files to /var/lib/boinc-client/projects/setiathome.berkeley.edu

Note: You might need root access to copy the files. If so enter.
sudo su

You will need to change the owner of the files just copied.
chown boinc:boinc *

Start up BOINC and enjoy.

Well, I reconfigured my Lotzacores rig, and added 2 extra video cards, but they system initially said 5 GPUs found, and after a few reboots and some issues, I ended up going down from 6 to 5 to make it happy. It's on a EVGA SR-2 board, has 8 slots, 4 are 16x, but for whatever reason, only wanted 5, so thats what it has, 4 950s and one 1050Ti.

Installed Mint 18.2 with KDE (not too sure I am a fan of this desktop, but I'll roll with it for the time being) and that went pretty well, then went into there it asked if I wanted to use the proprietary drivers, which was a Nvidia 376. something I believe, so said yes to that. It said I had to reboot, so did that, it started booting, got part way thru where it looked like it was going to load the GUI, and rebooted again. This time it came up ok. Then did the sudo boinc command, sudo apt-get install boinc-client boinc-manager and after it ran, this is the list of info in the window:

Ok, so there it sits, but no icons, no BOINC in any menu that I could find, so I don't know how to start it to configure it, and move on down your list. Am I missing something? (obviously) lol

Me and Linux, back at the dance again, but this time. I'd like to lead... Grr

In the Menu, you should have a search box, type boinc and it should find it.

If you right click what you find, you should be able to place a shortcut on the Desktop.

Most people go with the Cinnamon version, I'm not exactly sure offhand how that one looks like. But I believe you can change it.

THANK you. That was it, got it copied to the desktop, and got it configured to my account, immediately set it to NNT, but one thing I didn't figure out when I was installing the system initially, was how to name it what I wanted it to be named. Is that something that I can do at this stage of the game? Also, I am in the middle of the update manager running, so I will wait for the next step, I think Petris secret sauce, until they are all installed, there sure were a ton of them, I hope that was a wise thing to do?

*edit* do you know if the Cinnamon version is more 'windows like' than KDE? If so, any guesses as how to switch it, if it is even possible, without muffing everything I just did up?

*edit 2* just got done with the updates, it didn't even ask me to reboot. Amazing. So, following the instructions, I downloaded Petris file, extracted it, and tried putting it into the stated folder. When I was working my way down the dir tree, I get to root>var>lib>boinc-client, and see notices and projects, but when I click on either one, it just gives me a box with a red X and says The specified folder does not exist or was not readable. Even though it appears to be right there. Any suggestions? Thanks!
