Memory retention on Xeon Phi in OpenMP 4.0

Hello,

some time ago, memory retention between offloads on Xeon Phi in OpenMP 4.0 was supported only within a lexically structured scope  ( https://software.intel.com/en-us/forums/topic/520644#comment-1796781 )

Have things changed as of Parallel Studio 2015? Can we offload data from one function and re-use from another?

Thanks!

Andrey

The word I have, from an authoritative source, is that unstructured data movement is not in the 15.0 compilers but will be in the 16.0 compilers.
