1) Message boards : Number crunching : Using GPU? (Message 64415)
Posted 24 Mar 2016 by Profile Coleslaw
David, I have had several 8400 series cards over the years. They still outperform some older quad core CPU's but are getting to the point where modern CPU's are more efficient. I still use the GPU on some of mine, but can tell you that some projects just demand too much for them. If it is your primary display, I would not recommend using it as you may experience the drivers crashing regularly when BOINC suspends the task. There are fewer and fewer projects supporting this card as it is one of the earliest CUDA capable cards made. Moo! does well last I checked. BitcoinUtopia is a horrible option for one if you pay for the electricity. However, the points it will score will surpass any other project. It will certainly still run on other projects like SETI & Einstein, but I have found those projects to be a little harder on the cards than some of the others.

I see that you have an 8400GS. IIRC this was the medium quality out of the 3 versions. There was the 8400, 8400GS, and 8400 GS. Some of the mobile ones had less the 128MB video on them. Some were 8 CUDA cores and some were 16. Most are 8 though. Since yours has 512MB of memory and the card has a small number of cores, I would certainly not try to run more than one work unit at a time at any of the projects.

I'm glad they took my suggestion serious. Now if only they could come up with an easier way for supporting other projects as well. Converting to a traditional currency shouldn't be too much of a problem...

The Vault Admins have posted a list of projects to be added to, and removed from the Vault. Now is your chance to have your say on what is being proposed. Here are a couple of links to the public discussion about what the Admins have come up with.


4) Message boards : Number crunching : Android x86 app (Message 60901)
Posted 1 Feb 2014 by Profile Coleslaw
Berkeley released Android version of BOINC 7.2.39 which now supports x86 processors. Since more devices and virtual machines may start using Android as a platform, it would be nice to have a working app.

AMD will be adding ARM processors to Opterons http://www.amd.com/us/press-releases/Pages/amd-to-accelerate-2014jan28.aspx in servers soon that will also support 64bit. It is only a matter of time before there is a 64 bit version of Android. Many may find this as an attractive option over other Linux installs. BOINC updates much easier in Android and can do so automatically.

I currently have Android 4.2 in a VM for testing and can confirm BOINC installed just fine as intended.

And can we have the badges also show up on our Teams list so that we can see how we match up to each other? Some of the other badge projects do this.
6) Message boards : Number crunching : ARM Devices (Message 57848)
Posted 8 Apr 2013 by Profile Coleslaw
I think the more important thing to look at is when ARM is to that point, so will we. We already have the software for many devices. Both tablets and mobiles with at least two OS's now supported. My two year old Cell phone produces work units equal to some older laptops. I'm sure your arguments are that those laptops are no longer efficient to modern PC's. And that is true, but they are still used because that is what people already have. I didn't buy my phone to crunch for science. But I have it and it is capable, so therefore I use it too. It isn't a power hog, so that isn't noticeable. I don't crunch while it is in my pocket. I do crunch while it is charging at my desk and while I'm sleeping. So, discounting it because it is a waste today is idiocy. SETI wasn't trashed because the millions of PC's available weren't the highest most efficient systems. It was supported because the resources were available. ARM is no different.

matszpk, do you have plans on getting nativeBOINC to work on the x86 Android version? I currently am testing 4.1.1 in a Virtualbox. Your app will download and start installing, but it gets to the point of unpacking native client and then never finishes. I have tried installing it the normal way and with the older device option as well with the same result. I'm sure as Intel continues to work on x86 handheld devices, this will become a necessity.

Glad to see PrimeGrid added an app for The Riesel Problem (Sieve). Keep them coming!

Never mind...I found it. Under manage client there is an option for "Do network communication now" that does this.

Is there a way to manually "update" the project to send completed work? I am not seeing the option and this would be rather handy on a phone that would periodically need to shut down the client.
11) Message boards : Number crunching : Where's CUDA? (Message 27416)
Posted 9 Jul 2009 by Profile Coleslaw
My 8400GS card used to push GPU Grid WU's but typically errored out with an error on my Windows system telling me the drivers failed. There for a long time SETI would even crash Windows XP and Vista using all the CUDA capable drivers. Online searches showed many people had problems with this (not for BOINC, but for video players in combination with audio drivers), so I think it is more of a nVidia thing in my case. I recently started SETI GPU usage again and it seems to be more stable. I don't get BSOD's now, but I do still get the drivers failing message from time to time.
