21) Message boards : Number crunching : Linux apps query (Message 1839076)

Post:
After much frustration with Windows updates I am looking at switching to Linux for my CPU crunchers. Are there optimised apps available, as in AVX or similar to take advantage of recent processor features?

I'm familiar with Debian so that will probably be my target OS. Initially I am looking at switching my i7-6700 machines.

That's what they invented A/C for :)

She who must be obeyed doesn't like using it. That is until it gets humid :-(

I ordered a couple of GTX1060 (3Gb variety). They're in transit at the moment.

I haven't been able to run anything in the last couple of days due to the heat (38 degrees C in Sydney today).

We finished v7 ages ago. We're on v8 now. Stop your BOINC client, delete the app_info and restart BOINC. It should get the stock app.

When I will get feedback from already provided build I could try to disable this pragma too.

Sorry for the delay. Work intervened.

Another set running using new app. Same hosts as before. I also snagged some guppies this time.

Looking through the results it would seem v8.19 supplied by beta validate most of the time. The r3525's are almost all inconclusive or invalid.

So try test iGPU build.

8 cooking on beta using 8.19 app as we speak. Will take a couple of hours for them to be done. All are Arecibo at the moment, no sign of guppis.

If it helps I have a bunch of i7-6700 (Skylake) machines with HD Graphics 530. All are running Win7 x64. Currently have GPU disabled in BOINC due to this issue. Happy to help test on here or beta. Currently have driver 4501 on them but have older drivers as well.

After Christian Beer changed the beta validator for BRP4's I found them all pretty much validating. Unfortunately when one selects beta apps at Einstein it gives all different work types which didn't work on HD Graphics 530.
30) Message boards : Number crunching : Thought(s) on changing S@h limit of: 100tasks/mobo ...to a: ##/CPUcore (Message 1812841)
Posted 26 Aug 2016 by Profile MarkJProject Donor
Post:
Most of my machines are i7's so they get 100 / 8 threads = 12.5 WU per thread.

If we expand on that by saying we get 12.5 x number of threads then it could work for the smaller (single thread) machines as well as the larger (56 thread) machines. I would suggest we make it something like 15 per thread. Its simplistic and achievable with the current infrastructure.

A more long term approach might be to increase that number based upon the average turnaround if the host is considered reliable. It could also be applied the other way to reduce the number if the host is unreliable.

Do we really need to differentiate between processors and thread counts? I mean what would I want to do differently in this case? From a task scheduling point of view I have the same number of available threads that want feeding regardless of my physical processor count.

Post:
Yes, that's basically why I've been working on configuration and dispatch infrastructure. Without that, the base code has to be able to run on a G80 class Pre-Fermi GPU (e.g. 32 max registers) and blocking sync only, minimising CPU use (limited to no usefulness of Cuda streams).

Jason, do we really have to support back to the G80, given Nvidia have thrown them in the legacy bin? Can we convince the powers that be (Eric?) that the lowest supported GPU should be a Fermi for future developments. It sounds like a lot of effort to support old hardware.

According to Downloadcenter.intel.com there is a 4380 beta driver available. No mention of 4360 on the Intel site so it's probably a Microsoft Win10 special version.

The 4380 driver lists the following fixes
KEY ISSUES FIXED:

Just Cause 3 - game crash
Microsoft Enhanced Video Renderer - API crash
Project CARS - game crash
F1 2015 - game crash during built-in benchmark
Angry Birds - corruption after using “Maximize” icon in game window

Quake IV - corruption resuming from standby mode
Fallout 4 - game crash when game is loading
LEGO Minifigures Online - command list reset lock takes long time (4th & 5th Gen)
Wolfenstein The New Order - game crash


As you can see it's all game stuff, no mention of OpenCL so I wouldn't hold your breath on this one fixing anything, nor the 4360 that you've got.

I've raised a bug with Intel about their OpenCL not working properly (too many validation errors) along with another user eta over at Einstein. Intel told me it's the OEM responsibility, so they don't want to know about it. My tasks run fine, just fail to validate, but then I'm running Win7 x64 on my machines.

The only thing I can think of, I suspended an active task to start my first v8 task, maybe the stot was not emptied properly ... no one will ever know.

You might want a more recent BOINC version (than 7.4) to get the fixes for emptying out the slot directories. The current release version is 7.6.22.

Installed on a Intel cruncher with iGPU.

It downloads the latest drivers when you install. After rolling back the iGPU driver to the one I had before it couldn't detect my screen so I got stuck at 1024x764 res. You have no control over the drivers, it just downloads the latest and installs it. After rolling back to original it downloaded the latest one again.

Edge was quick. Pity about the driver crap. I've gone back to Win7.
37) Message boards : Number crunching : Using BOINCView. (Message 1704589)
Posted 24 Jul 2015 by Profile MarkJProject Donor
Post:
I have a couple of Parallella's (they run Ubuntu) and a few Raspberry Pi's (they run Debian). I use BOINCtasks with them. While BOINCview will work it can't do half of what BT can do.

From what I gather the author of BV passed away so it hasn't been updated and the source code was not made available.

To manage machines via either one you'll need to setup a gui_rpc_auth.cfg and remote_hosts.cfg. They go in the BOINC data folder. The remote_hosts tells it which computers (or IP addesses) are allowed and the gui_rpc_auth has a password, although it can be blank. You need to set the same password in BV or BT when you configure the computers that its going to control.

If you have a firewall configured on your number crunchers you'll need to allow the BT machine through.

Ah, only optional: https://support.microsoft.com/en-gb/kb/3064209

There seem to be a number of Windows 7 users complaining they can't boot after installing this one, so tread carefully.

Another gripe seems to be its getting offered to AMD-based machines as well.
39) Message boards : Number crunching : Curious about cc_config.xml (Message 1696721)
Posted 29 Jun 2015 by Profile MarkJProject Donor
Post:
BOINCtasks also has the ability to edit the cc_config (even of a remote machine) and the end result will be a file with all the tags even though you may only have changed one of them.

Personally I prefer to edit the thing by hand so you don't get all the tags.

A question for you guys testing it.

From what MS is telling us is the Pro version will be able to run 2 VM's and the Enterprise version has no limit. So does that mean you can only run 2 VirtualBox tasks at a time on Pro?
