<div class="moz-cite-prefix">It's more likely that internal R&D
funds are prioritized. Resources are not infinite. For example, if
fixing geospatial indexing in a distributed cluster needs R&D
money, it's more likely to get that funding than a language with
limited adoption prospects.<br>

IIRC, Fortress and Chapel were both funded through the DARPA HPCS
program. HPCS wrapped up a few years ago now. So, the "working
with DARPA" part is only partially factual. I also seem to recall
that Fortress did not survive a down-select in the first phase of
HPCS and that Sun had to go it alone to continue the project.<br>

<p class="MsoNormal">I thought this would be of interest to
LLVM developers: The Fortress project, which was an attempt
to create a very advanced language with implicit
parallelism, parametric polymorphic types and many other
cutting edge language features, has announced that they are
winding down the project. What I found very interesting was
that one of the reasons they gave was the lack of a suitable
execution environment:<o:p></o:p></p>

<div>
<p class="MsoNormal">"...over the last few years, as we
have focused on implementing a compiler targeted to the
Java Virtual Machine, we encountered some severe
technical challenges having to do with the mismatch
between the (rather ambitious) Fortress type system and
a virtual machine not designed to support it (that would
be every currently available VM, not just JVM). In
addressing these challenges, we learned a lot about the
implications of the Fortress type system for the
implementation of symmetric multimethod dispatch, and
have concluded that we are now unlikely to learn more
(in a research sense) from completing the implementation
of Fortress for JVM."<o:p></o:p></p>
