Re: [OMPI users] cluster with iOS or Android devices?

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

Re: [OMPI users] OpenMPI-1.6.3 & MXM

Konz, For whatever it is worth, I am in the same boat. I have CentOS 6.3, trying to compile OpenMPI 1.6.3 with the mxm from Mellanox and it fails. Also, the Mellanox OFED ( MLNX_OFED_LINUX-1.5.3-3.1.0-rhel6.3-x86_64 ) does not work either. Mellanox really needs to step in here and help out.

Re: [OMPI users] cluster with iOS or Android devices?

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

Re: [OMPI users] cluster with iOS or Android devices?

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).

[OMPI users] OpenMPI-1.6.3 & MXM

I tried building the latest OpenMPI-1.6.3 with MXM support and got this error: make[2]: Entering directory `Src/openmpi-1.6.3/ompi/mca/mtl/mxm' CC mtl_mxm.lo CC mtl_mxm_cancel.lo CC mtl_mxm_component.lo CC mtl_mxm_endpoint.lo CC mtl_mxm_probe.lo CC

I've attached a small sample program that demonstrates the problem. You can toggle working/non-working behaviour by toggling commenting on line 27. I've tried to open a bug report, but the system isn't letting me register for Trac: Trac detected an internal error: KeyError:

The openib BTL and BLCR support in Open MPI were working about a year ago (when I last checked). The psm BTL is not supported at the moment though. >From the error, I suspect that we are not fully closing the openib btl driver before the checkpoint thus when we try to restart it is looking for a

Re: [OMPI users] (no subject)

Pramoda, That paper was exploring an application of a proposed extension to the MPI standard for fault tolerance purposes. By default this proposed interface is not provided by Open MPI. We have created a prototype version of Open MPI that includes this extension, and it can be found at the

Re: [OMPI users] cluster with iOS or Android devices?

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

Re: [OMPI users] cluster with iOS or Android devices?

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

Re: [OMPI users] cluster with iOS or Android devices?

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
