Does anyone know if the code for the book is available. On the Fortran wiki page, there is mention of an associated website for code download but I am unable to find any such site.
Alternatively, does anyone have the code for download.
Additionally, I am intending to invest some time in mastering co-arrays. So, what is the status/future of it. I would prefer to be stopped now before I go down the rabbit hole.
@certik : What is its status in LFortran?
We don’t support co-arrays yet. Overall we are still in alpha stage, but making good progress towards beta with compiling more and more codes.
There have been several threads here over the last few years that discussed co-array performance and usage. You might go back and read those because they give you a broad view of co-arrays. My personal experience is they work very well and are competitive with MPI on large HPC systems with the hardware to support PGAS. Trying to run them on plain vanilla multi-core workstations has been disappointing. I think the NAG compiler is your best bet if you want to use co-arrays on workstations because they aren’t built on top of MPI but use their own shared memory subsystem. You should also look at @milancurcic excellent book

FWIW, the coarray codes described in App. C of MFE can be freely downloaded using the ‘codes’ button at the Companion website.

Since you mentioned Robert Numerich’s book, I would like to share a self-study/experimental repository I wrote a while ago, which essentially implements a multidimensional (using PDT) forward partitioner as described in Chapters 3 and 4 of the book:
I tested it with fpm + gfortran + OpenCoarray. Hope it helps!
