Message 9897 - Posted: 5 Oct 2010, 21:32:33 UTC - in response to Message 9896.

What about newest mac and ati cards, getting some new macs with ATI Radeon HD 5750, no use here?


No use anywhere AFAIK. AMD and Apple don't get along because Apple chose to use Intel processors on all their MACs leaving AMD out in the cold. AMD seems to have done likewise and doesn't provide complete Radeon drivers for the MAC and without CAL and Brook support for ATI cards, the Collatz app won't run.

The official boinc for Android is available here

https://groups.google.com/forum/#!forum/boinc-android-testing

Would be nice to see Collatz also there!

A number of apps are still working, see also native boinc.

What percentage of BOINC users are Android users? What percent of computing power are the Android devices (given that they only crunch when charging)? I have plenty of higher priority items to work first on such as:
Fix "thread=0" issue with Linux x86_64 app
Build, test, and deploy Linux i686 app
Build, test, and deploy OS X OpenCL and CUDA apps
Fix sporadic checkpoint issue and redeploy ALL app versions
Build, test, and deploy new solo CPU apps
Set up mini_solo_collatz app

At present, the needs of the many outweigh the needs of the few.

Message 18872 - Posted: 19 Mar 2014, 18:51:32 UTC

At the moment I am happily crunching solo_collatz on my GT 610 under Ubuntu 12.04.4, using Nvidia driver 331.49, but I would also like to start using my CPU, an Intel® Core™2 Duo CPU E8400 @ 3.00GHz as well.
Would the Nvidia driver work for the CPU too, or do I need to install another driver for that, and if so, which one?
I'm finding the information on the Home Page a bit confusing.

In the beginning Boinc was designed to ONLY use the cpu, so it does that by default, you just need to go into Your Account on the webpage and enable the checkbox to let the cpu units flow. It is under 'preferences for this project' and then you will see:

Use CPU
Enforced by version 6.10+ no
Use ATI GPU
Enforced by version 6.10+ yes
Use NVIDIA GPU
Enforced by version 6.10+ yes
Use Intel GPU
Enforced by version 7.2+ yes

You can see I have the gpu units allowed but the cpu units NOT allowed, change the cpu line to yes and then your pc's should start getting cpu units too.

For one WU per core, check:
"Use CPU
Enforced by version 6.10+"

For one WUs using all cores at once, check:
"OpenCL for AMD/Intel CPUs (opencl_amd_cpu)"

The latter will use 100% of every core for CPU apps so chances are you want to use the first option if also running GPU applications.

There are not settings whatesoever within OpenCL to use only X of Y resources. So, it either runs on all cores or not at all. OpenMP allowed a max thread setting so I imagine it will get added to OpenCL at some point.

So if you uncheck those cpu boxes you must also check the solo collatz box so you can still get cpu units, correct?

I answered my own question and am now getting single cpu core units.

Yeah once you told us how to turn the multi core units off there was little left to figure out, I kind of stumbled into it. I DO like the option though, thanks!

The following platforms have been tested:
Operating Systems:
Windows XP or later (32 and 64 bit)

GPUs
nVidia - 8400 GS or later
AMD HD Radeon 48xx or later
Intel - HD 4000 or later

At present, all application utilize OpenCL which requires an OpenCL driver from nVidia, Intel, or AMD.


Still getting problems with ver 1.21 x64 on intel GPU.

my desktop i7-4771 with HD4600 (win 10 x64 es) is crunching perfectly 1.21 x64

my Surface i5-6650U with Iris graphics 540 (win 10 x64 es) all downloaded GPU work is ending with error with less than one second running. but I'm able to GPU crunching with app of SETI (opt. KWSN) & stock Einstein without error??

I tried running tasks (Collatz Sieve v1.21 (opencl_nvidia_gpu)) with my GeForce GTX 980 (GeForce Game Ready Driver version 357.86 on Windows 10 64Bit, OpenGL 4.5 (GeForce GTX 980/PCIe/SSE2 with 386 ext.)) and got 107 errors before I even noticed what was going on...

PS: "OpenCL support is included in the latest NVIDIA GPU drivers...", so that should not be the problem.

FAH can't use 375x drivers, maybe collatz can't either? The drivers were downloaded direct from NVIDIA? Win10 cuts out part of the drivers when it installs.

Yes, I even installed the "NVIDIA GeForce Experience"-app to get the most recent drivers (which perfectly work with SETI@home, GPUGRID and Asteroids@home). And I really don't want to install older drivers for my new GTX because this would only end in a mess like with VirtualBox where you have to optimise your version for nearly every BOING-project...

PS: forgot to mention: (OpenCL: OpenCL 1.2, GeForce GTX 980 | CUDA: GeForce GTX 980 CC:5.2) maybe those numbers changed due to new drivers coming in today (375.95)

I'm having the same issue on 2 GTX 960 cards since NVIDIA went to OpenCL 1.2 (1.02 as Collatz calls it). The cards ran a few thousand Collatz tasks comfortably with all of the 35x.xx and 36x.xx drivers in XP 32-bit. Since I moved over to XP 64-bit and Windows 10 64-bit as a dual boot, following a HDD failure, neither OS will run Collatz with those cards, they just fail every task.

[2] NVIDIA GeForce GTX 960 (2047MB) driver: 368.81 OpenCL: 1.02 for XP-64
and
[2] NVIDIA GeForce GTX 960 (2048MB) driver: 378.66 OpenCL: 1.02 for W10-64
(not sure why the memory discrepancies happened as its the same PC?)

I also have an android tablet with OpenCL 1.2 that suffers this issue:
INTEL Intel(R) HD Graphics (528MB) OpenCL: 1.02 (Android 3.10.62-x86_64_byt-g105afb7 (Android 5.1))

But my OpenCL 1.1 Laptop runs fine (just a little slow on the latest WUs) even with the later drivers.
NVIDIA GeForce GT 630M (1024MB) driver: 372.70 OpenCL: 1.01, INTEL Intel(R) HD Graphics 4000 (1624MB) OpenCL: 1.01 (Windows 7)

OpenCL 1.2 is working normally with SETI and Einstein, but since I was crunching well with Collatz before, I'd love if someone can find me a solution. So far the only difference in the XP-32 and XP-64 setups are Boinc version and the obvious 32-bit to 64-bit changes. Whether OpenCL or the new WUs are playing a part I'm not sure.

I have, now have it working with the latest driver after a clean install so something clearly went bad when I last updated. Still no luck with the tablet, though.
