[J3] (SC22WG5.6239) Paper: "History of Coarrays and SPMD Parallelism in Fortran" from three of our own

[Steve Lionel]

All:

Bill Long, John Reid, and Jon Steidel have written a detailed and 
fascinating paper on the history of coarrays in Fortran, including all 
the twists and turns in the development of that part of the standard. 
Large parts of this story were unknown to me, and I learned a lot. It 
was just published in the "Proceedings of the ACM on Programming 
Languages" and is available for free download at 
https://dl.acm.org/doi/abs/10.1145/3386322 - I don't know if it will 
stay freely available so it is worth downloading the PDF if you want to 
keep it around.
