The connection on/off the iPad looks like an Ethernet port, I believe - but you should check that. Alternatively, you can send/recv across the wifi connection. No idea of the relative speeds, but you should be able to google that data. On Nov 30, 2012, at 3:35 PM, shiny knight

I totally get your point Jeff, and thanks for pointing it out...this is an aspect that I didn't consider yet. Power should not be an issue, since the devices are plugged in. Now I need to evaluate exactly how much power I can pull while the device is connected to the computer, compared to the

Thanks a lot for the pointers Ralph. So I just check out the source for OMPI and build it in Xcode with target iOS? Sounds pretty straight forward. I will probably have to deal with errors but it seems that you did it already and it should not be that hard (I am still learning many things).

Not to throw cold water on this, but I think the canonical problem cited with doing distributed computations on mobile devices is the power requirement. Meaning: if the devices are running on battery, you're really not going to get much computation out of them. And if you have them plugged

Just an FYI: xgrid is no longer being distributed or supported. I'd start by first building OMPI against the iOS simulator in Xcode. You may run into some issues with the atomics that will need addressing, and there may be other issues with syntax and header file locations. Best to resolve

Thanks for all your replies. As now I have access to 3 iOS devices and 1 Android, so if possible I would be oriented to pursue more the iOS route. So it seems that there is not yet a simple way to do so on these devices (Thanks for the paper posted Dominik); I will have to look deeper in that

Greetings Ladies and gentlemen, There is one alternative approach and this a psuedo-cloud based MPI. The idea is that MPI node list is adjusted via the cloud similar to the way Xgrid's Bonjour used to do it for Xgrid. In this case, it is applying an MPI notion to the OpenCL codelets. There are

I seem to vaguely recall someone porting OMPI to the iPad at one time as part of a large-scale, impromptu cluster demo at some conference - everyone was supposed to bring a computer, network them all into a large "cluster", and then run a benchmark to see how fast it would work. I can't find or

You might want to post in beowulf mailing list see cc and you want to install linux of course. OpenFabrics releases openmpi, yet it only works at a limited number of distributions - most important is having the correct kernel (usually old kernel). I'm gonna try get it to work at debian soon.

I was looking for some info about MPI port on iOS or Android devices. I have some old devices that may result useful, if I could be able to include them in my computation scheme. OpenCL runs on iOS and Android, so I was wondering if there is any way to have an old iPhone/phone or iPad/tablet
