Will this work for iOS? #18

Closed JetForMe closed 10 years ago

JetForMe commented 10 years ago

iOS doesn't allow the use of dynamically-linked libraries in submitted apps. Is it possible to link the runtime statically?

jcownie-intel commented 10 years ago

The OpenMP* runtime library can be built statically (for instance we ship a static library with our commercial compilers on Linux/X86). However, since I haven't been involved in the ARM/iOS port I have no idea what that does, or whether it even exists! (There's a separate whole discussion to be had about the sanity of using the OpenMP programming model on a phone/tablet which is a very different environment from the supercomputers for which OpenMP was developed, but that's probably not for now!)

Thanks for the reply. In some simple cases, we replaced our OpenMP code with GCD calls, and saw improvements. But it would be better if we could get full-up OpenMP support. Thanks!
