Use these parallel programming resources to optimize with your Intel® Xeon® processor and Intel® Xeon Phi™ coprocessor.
My questions are very simple. We have intel visual fortran 2015 and fortran subroutines parallelized with OpenMP directives. Is the compiled code be capable of using all the available threads on the Intel Xeon Phi? Would it be required to modify the code to make it compliant with these new processors?
Our intention is to use already-parallelized code on Intel Xeon Phi or a similar MIC processor. Any suggestions or links on how to do this?
I've been using an Intel Xeon Phi A3102 coprocessor with no issues for about 9 months now, but I recently started having issues running code natively on the device. When attempting to run a program via micnativeloadex I get the error message "Supplied binary does not match the Intel(R) Xeon Phi(TM) coprocessor that is installed", which I've never seen before. I updated the software on my (composer, etc) which does not seem to have solved the problem. For reference, I'm using RHEL 6.6. Some system information collected with micinfo:
Updated my mmic system to Centos 7.1, and when trying to compile hello_world with
ifort -mmic hello_world.f90 -o hello_world.f90
get a link error:

Modern high performance computers are built with a combination of resources including: multi-core processors, many core processors, large caches, high speed memory, high bandwidth inter-processor communications fabric, and high speed I/O capabilities. High performance software needs to be designed to take full advantage of these wealth of resources.
