Topics: blas, coarray, fortran, fortran-package-manager, linear-algebra, matmul, matrix-multiplication, matrix-vector-products, transpose

Classification scope and review notes

Methods m1 through m4 are checked for rectangular matrix multiplication, all transpose combinations and a matrix-vector product. The demo is single-process and does not validate every implementation or coarray branch. At this pin a single explicitly false transpose flag is misrouted; the demo passes both flags whenever either is specified. Separate failing probes and the successful workaround are retained.

Package dependencies

Resolved GitHub repositories used by the verified playground build, combining direct and indirect dependencies. This list does not describe internal module dependencies or native system libraries.
