Toni, will these work units be GPU, CPU, both? I know to some that may be a silly question but GPUGrid has dabbled with GPU, CPU, ARM (Android), and virtualbox in the past. Just wanted to know what to look forward to.

Also, if serious consideration is being discussed keep in mind the latest 5.2 versions of Virtualbox needs updated vbox wrappers provided.

I can confirm the one box I had upgraded fails every work unit at the moment in my testing at Source Finder.

Good. Just don't be delusional in the process...

I'm actually arguing for keeping the Linux version rather than replace it. Telling me to not bother because you like them isn't acceptable to me. You play it off like they run great because you had little issue with them. You can scour their forums over and over to find the average user does not agree. You are right about LHC not being in its present form as it would still be Six Track running traditional work and the others doing it in house or eventually adapting things different. Cosmology would just be down one application as well. I don't see how that is relevant. Either way. My vote is to not embrace virtualbox if it means pulling non-virtualbox work.

There is actually more to it than that. I have ran every VM project as well and have done so with a whole slew of different hardware and software setups. There is a huge reason why those projects do not get much support. LHC only has a large user base now because it merged the projects with the original Six Track project. Event still, the virtualbox applications remain less popular. Keep also in mind that these projects have problems with new releases of Virtualbox as they have right now. If I make my own VM using the latest release, it does not suffer the same. The only advantage to a vbox application is to allow the scientist to have an easier time compiling a single application. This may sound great to them, but the amount of lost time on the end user far exceeds their lost time.

Also, for reference if it helps, GPUGrid attempted vbox applications back in 2014. Discussion started in 2013 http://www.gpugrid.net/forum_thread.php?id=3542#33874

I would say don't mess with a virtualbox application if it would replace the Linux application. Too many headaches. If someone is running Windows, they could easily set up their own virtualbox VM and run it under Linux with the standard app. Win-win for everyone that way. It also give the user more control over the VM. Just my thoughts on it. Also, more and more people are migrating to Windows 10 and it is the direction all new machines are following. So, might as well prepare for the future.

Since it’s the first time we have a CPU app out, I’ll test the behavior of GPUGRID with a relatively large batch that you will see soon.


I just started reading this thread. I thought I would point out that there was a multi-threaded CPU application back in 2014. It just wasn't necessarily for Quantum Chemistry.

In short SOMEONE has to pay to keep the projects running, if the grant money stops flowing and the users won't pony up some cash, then they have few options to keep running. I personally would NOT want click thru ads at every project just to read the forums, and to keep them running.


The other issue you have with asking donors for money is not knowing if that money will actually reach intended use. Some Universities will accept that money and then maybe a very small percentage will actually make it to the project. Carl over at QCN explained to me once that efforts to get funding for them was pretty much pointless in this way. He said that it equated to maybe getting the staff beer and pizza one night because the donated funds just weren't actually divied where the donors intended. So, when volunteers are asked for donations many will ask the skeptical questions. However, at every project there is some die hard who jumps to the defense and claims how reputable such organization is and how you can fully trust them. Seriously, the people that run Universities aren't much different than other organizations. Money goes where it can grow first and foremost. As for a For Profit website for stats keeping, those issues are up to them. I do support when I can because I use their sites. However, my "donations" aren't much. I have however seen the ads. I have actually spoken with a few other projects after suggesting Milkyway to BU and Carl at QCN. POGS is one of them and are considering the opportunity. It is a pitty that it isn't better received. I also appreciate that BU has recently reduced fees a second time to 10%.

With Xeon Phi's dropping in price quite rapidly, has there been any renewed consideration for possibly developing to support these cards?

I figure the multi-thread CPU app could really take advantage of these.

It is the 9th gpus that pushes it over. 0-8 makes 9


Yes. Our app has a limit of 8 GPUs/host. I'll see about getting that fixed, but it won't happen for a wee while.

Thank you for the confirmation. This allows us to move on and not waste more time testing and tweaking.
