This doesn't sound like a linking problem; this sounds like there's an error in your application that is causing it to abort before completing. On Jun 25, 2014, at 12:19 PM, Sergii Veremieiev wrote: > Dear Sir/Madam, > > I'm trying to run a parallel finite element analysis 64-bit code on my >

Sounds like you have a problem with the physical layer of your InfiniBand. You should run layer 0 diagnostics and/or contact your IB vendor for assistance. On Jun 24, 2014, at 4:48 AM, Diego Saúl Carrió Carrió wrote: > Dear all, > > I have problems for a long time related with mpirun. When

2014-06-26 Thread Adam Jundt
I'm currently working towards setting up a single node system with a xeon phi card. We have intel compilers (v.13.1.3) installed and I was able to get the standard openmpi (v1.6.5) to install. Right now, I am just hoping to run codes natively on the xeon phi. When trying to compile a hello world c

I'm on the road today, but will be back tomorrow afternoon (US Pacific time) and can forward my notes on this again. In the interim, just go to our user mailing list archives and search for "phi" and you'll see the conversations. Basically, you have to cross-compile OMPI to run on the Phi. I've be
