Current status on the compiler side (GCC 4.10 trunk): Full support of
Fortran 2008 and of the TS18508 collectives co_sum/co_min/co_max except
for:
â No support yet for allocatable/pointer components of coarrays (i.e. no
remote access to those via explicit component reference or via intrinsic
assignment of the coarray, which should copy over allocatable components)
â No locking, critical and atomics support
â A few known bugs, e.g. with polymorphic coarrays in corner cases. I
assume more corner cases will be found once there are more users.
Current status for libcaf_single as shipping (and automatically build)
with GCC 4.10: Besides the points above, the following is not yet working:
â Coarrays with Vector subscripts.
Thanks for your and Alessandro's work. Alessandro presented this work
and results
at the J3/WG5 meeting this week - impressive !
How does this work, configure-wise ? I have OpenMPI installed on my
system in the usual place; will a trunk configure find this automatically ?
Thanks in advance,
