Improved & Official Windows Support

New Functionality

OpenCoarrays is now officially supported on Windows using the Intel MPI Library and a lightweight linux-like environment on Windows, like MSYS2. Note that the wrapper scripts likely still require a bash shell. CI testing on windows has been added to ensure proper functionality moving forwards.

Bug Fixes

• Made locating IntelMPI runtime library on windows more robust (PR #782)
• Thanks to @band-a-prend for fixing an issue that would occur when using clang (PR #777)

Bug fix, installation improvements, and GCC/macOS version updates

Bug fix

Issue #511: the shape of coindexed multidimensional array component now yields the correct answer. 💠

Installer updates

1. If install.sh builds GCC on macOS Catalina, it finds and uses the requisite macOS software development kit (SDK) header files. ⛰️
2. GCC 10.1.0 is now the default minimum version used or installed by install.sh. Users may force the installer to use a lower version by invoking install.sh with the -f, -c, and -C arguments. 🆕
3. Pull request (PR) #705 fixes an error in the compiler version-check code invoked by install.sh.
4. PR #705 switches the GCC download mechanism to git to address two issues: 📫
   • GCC development branches: the previous default (svn) can no longer be used because GCC has adopted git.
   • GCC released versions: the previous default (ftp) is disabled on many systems for security reasons.
5. Other minor installation improvements. 🏗️

Co_broadcast derived types; installation enhancements & bug fixes

New functionality

• When using GCC versions >= 10.0.0, co_broadcast now supports derived-type arguments with allocatable components. 🎺
• When building GCC on macOS versions 18.7.0 (Mojave) or greater, install.sh now provides directions on how to install header-file prerequisites if missing. 🚧 🏗 👷

Expanded test coverage

• Revised an existing test of co_broadcast with derived type arguments so the test passes with GCC 7.
• Added a comprehensive test of co_broadcast with 15-dimensional allocatable and pointer components.

Bug fixes, installation enhancements, & documentation updates

• install.sh installer now passes newly required flags for building MPICH with GCC versions >= 10.0.0. 🇺🇸 🇩🇪 🏴 🇬🇧 🎏
• caf compiler wrapper now correctly falls back to dynamic linking. ☕️
• INSTALL.md and README.md now reference a comprehensive listing of package managers along with each one's status. 🚦

  • This was affecting distribution in some package managers, like AUR
  • e.g., https://aur.archlinux.org/packages/opencoarrays/#comment-693351

Improved Team Support & Partial Support for Collectives with Derived Types

New Functionality

• Full support for GCC/GFortran 9.1
• Partial support for co_broadcast with derived types (thanks to @afanfa!)
  • Limited to derived types without allocatable components, for now
• Performance optimization #630: An extraneous barrier was removed from form team (thanks to @nathanweeks)
• The team value in the sync team statement may be a child team, consistent with the standard, #655 (thanks to @nathanweeks)
• Updated build script diagnostic output and additional test for co_braodcast with DTs (thanks to @rouson)
• Elimination of some warnings when compiling with clang (thanks to @zbeekman)
• An install receipt including SHA256 checksums is now included in the installation (thanks to @zbeekman)
  • This will facilitate:
    • Robust uninstall scripts
    • Easier verification and enumeration of installed files and assets
    • Verification that the files have not been corrupted
    • Verification of reproducible builds

Bug Fixes

• #632: Image selector indices should be with respect to the current team (thanks to @nathanweeks)
• Automated Dockerhub builds of the OpenCoarrays master branch were failing and have now been fixed

Build reproducibility and csh environment bug fix

Minor Fixes and Improvements

• The builds are now truly reproducible:
  • The Fortran repeat() intrinsic function was embedding build path information and an alternate approach is used in its place
• A bug in the installer script caused incorrect output intended for csh users to add to their dot files
• Headers no longer include MPI headers if the build does not find MPI
