I didn't know this, but I seem to be right in the assumption that one can
not easily find distributed shared memory in more-available systems.

Scientific programming is among the ideal domains for DIPC. Linux is more
available than some of the systems you mentioned above, so I guess porting
such libraries will be a great help to many people.
This is not just about performance: People can develop and test their
applications on cheap multi-computers, built using Linux, and then run it
on more speedy hardware, if they ever need to.
Such things will also result in more programs being developed, as more
people will have the needed equipment to do so.
