Bug ID: 88076
Summary: Shared Memory implementation for Coarrays
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: koenigni at gcc dot gnu.org
Target Milestone: ---
At the moment, we only support coarrays using mpi (or if they only have single
image). Thomas & I are currently working on adding an implementation based upon
shared memory between processes that is maintained inside libgfortran. It will
be enabled by '-fcoarray=native'. This library will have to have a different
interface than '-fcoarray=lib'.
At the moment, we have written a basic library with the necessary interprocess
allocator, simple synchronization routines and the functions for creating and
handling the image processes.
I am currently working on trans-* to emit the new initialization code and to
emit the direct memory accesses. Once this is done I will upload the first
prove-of-concept patch.
I have opened this bug to track the progress and provide a forum for discussion
:)
