Hi, has anyone considered building gfortran for Debian with OpenCoarrays?
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 . 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. Before I submit an ITP, has anyone in Debian investigated this? best regards Alastair McKinstry [1] http://www.opencoarrays.org/ [2] https://en.wikipedia.org/wiki/Partitioned_global_address_space -- Alastair McKinstry, <alast...@sceal.ie>, <mckins...@debian.org>, https://diaspora.sceal.ie/u/amckinstry Misentropy: doubting that the Universe is becoming more disordered.
