OpenMP + MPI implementation possible?

Hello,

Seeing as both MPI and OpenMP are supported, would it be possible to do a hybrid between the two in order to utilize the epiphany cores?
For instance, the ARM processor runs MPI, and sends calls to the Epiphany processor via OpenMP. (both of which are possible, I'm just not sure about together.)

Sure, why not? MPI across multiple boards and OpenMP on the board sounds okay to me.

Hi!
I tried putting together two Parallellas in cluster using eth0.
I have been able to run 2 processes per Parallella as the nunber of Host Arm Cores.
I was not able to run on both the Parallellas the 16 Epiohany cores....

Failure.....

Any idea? Please?
