There are some differences down in the detail level, mostly as a result
of differences between hardware architectures, operating systems, as
well as what development found funding and what did not.
There are differences between GT.M on Alpha/VMS and GT.M on UNIX/Linux:
the underlying OS platforms are different enough that we have different
manuals for them - although the manuals are generated from a common
source with conditional text. The UNIX implementations support
identical implementations of the M language, but here are some examples
of the differences:
* Some platforms support a "Direct IO" flag which turns on the
O_DIRECT setting for journal IO, which can either speed things
up or slow things down depending on the IO subsystem.
* GT.M on Sun SPARC Solaris supports Sun RPC call-ins. The others
don't.
* The GT.M compiler on AIX, HP-UX and Tru64 UNIX creates object
files in a format that can be incorporated into .so shared
libraries. The GT.M compiler on Linux and Solaris does not.
* There may be differences in the ability to pass parameters in
registers when calling between M and C on the different
platforms, but I can't remember right now.
* A GT.M process on AIX can have fewer database files open at one
time than on other platforms (the limit is something like 9
caused by fact that each shared memory segment uses a segment
register).
