例としていくつか上がっています。

LFortran has a prototype implementation of the @fortranlang proposals for generics, they work both in LLVM and WASM backends, go ahead and play with them online at:https://t.co/MNY4gNwb6P

at the top left click on Examples -> experimental, select an example, then click on Run.

do concurrent

よく見てませんが、実行速度的に C++ と変わりない結果が出ているようです。

This paper is fascinating: FORTRAN do concurrent, when implemented properly, is competitive with directive-based parallelism for CPUs and NVIDIA GPUs (while being portable).

Also the nugget that 80% of ARCHER2 time involves codes that require FORTRAN https://t.co/qsvoXIgKr7
