COSMA is a parallel, high-performance, GPU-accelerated, matrix-matrix
multiplication algorithm that is communication-optimal for all
combinations of matrix dimensions, number of processors and memory
sizes, without the need for any parameter tuning. The key idea behind
COSMA is to first derive a tight optimal sequential schedule and only
then parallelize it, preserving I/O optimality between processes. This
stands in contrast with the 2D and 3D algorithms, which fix process
domain decomposition upfront and then map it to the matrix dimensions,
which may result in asymptotically more communication. The final
design of COSMA facilitates the overlap of computation and
communication, ensuring speedups and applicability of modern
mechanisms such as RDMA. COSMA allows to not utilize some processors
in order to optimize the processor grid, which reduces the
communication volume even further and increases the computation volume
per processor.
*/*: bump PORTREVISION after OpenBLAS upgrade
Remark: this souldn’t be necessary, because the version of the library is the
same, but due to many changes between these releases, it is safer this way.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
