OMPI support for Epiphany

Postby Farzaneh » Tue Jan 10, 2017 8:57 am

Dear forum members,

I would like to run omp4-epiphany example using ompicc on epiphany. I have already installed ompi 2.0.0, but I have faced the below error during running parallella-examples on epiphany:

[ORT warning]: Failed to open module "epiphany"

My second question is regarding variable allocation on each kernel's SPM. How can I handle allocation and data access remotely from different kernels?

Any help appreciated.
Thanks in advance
Farzaneh

some debugging has lead to:

/usr/local/lib/ompi/devices/epiphany/hostmodule.so: undefined symbol: ee_set_core_config
while the device module is to be loaded.

I will continue debugging, but honestly speaking I have expected less problems.

Hi,

OMPi 2.0.0 (+patches) is included in Parabuntu 2016.11, which can be downloaded from here:
https://github.com/parallella/parabuntu ... -2016.11.1

If you must build OMPi from source, use this tree for Parabuntu / esdk 2016.3+
https://github.com/parallella/ompi
