<p>Hi,<br>
</p>
has anyone considered building gfortran for Debian with
OpenCoarrays?<br>
<br>
Fortran as of 2013 is now a PGAS language [2], allowing parallel
programming. It does this by adding co-arrays, allowing running
images to access images on other nodes/cores directly rather than
requiring MPI, etc. This allows for performance benefits under the
hood as the compiler overlaps computation and communication .<br>
<br>
gfortran as built allows this syntatically using libcaf_single,
allowing coarrays to 'work' but not actually in parallel. It can be
built using OpenCoArrays, apparently (I haven't tried this yet),
which in turn uses mpich or openmpi.<br>
<br>
Before I submit an ITP, has anyone in Debian investigated this? <br>
<br>
best regards<br>
