US Navy seeks info on POSIX Ada binding implementations

[Frank Prindle]

The Navy's NGCR (Next Generation Computer Resources) program is using POSIX as
a baseline for developing an Operating System Interface Standard.  Ada bindings
to IEEE Std 1003.1-1990 have recently become a standard (IEEE Std 1003.5), and
work is well underway on Ada bindings to Realtime Extensions which will
soon amend 1003.1.  The NGCR Operating System Standards Working Group needs
information on Ada implementations which have incorporated or plan to
incorporate some or all of these interfaces into their delivered product,
either bundled or as an option.

Of academic interest are "wrapper" bindings for target systems which are
assumed to be running under control of a POSIX compliant operating system
already providing "C" (or some other language) bindings to OS services.

But because the NGCR program emphasizes MCCR (Mission Critical Computer
Resources) applications, which often utilize embedded processors and have
hard realtime deadlines, we are much more interested in the so-called "bare
machine" Ada targets.  Such Ada implementations typically include a vendor
specific realtime OS which supports the Ada Runtime Environment and, in
addition, usually supplies an additional set of vendor specific OS services.
In the interest of portability (as in the "P" of POSIX), it is desirable that
Ada vendors implement a standard set of service interfaces as defined by IEEE
Std 1003.5 (and eventually 1003.20 and others).  Since it is our goal to
determine how much industry support there is for current and future POSIX
standards, one aspect of this is the extent to which these "bare machine" Ada
RTEs will become POSIX compliant.

Therefore, if you are a vendor or user of existing or proposed products which
support POSIX Ada bindings (especially "bare machine" target implementations),
please contact me with information about these products.  I can be reached at
the email address or phone number listed below.
