clone(), pthreads, tasking GNAT?

clone(), pthreads, tasking GNAT?

[Thomas Koenig]

Is clone() stable enough for real work yet?

Is anybody working on a Linux pthreads implementation based on it?

Is anybody working on a tasking GNAT version which includes this
pthread version?

I don't know, but I'd be interested in any information on this.

There was a Project entry awhile back that made mention of a threaded
kernel and I beleive clone() was created for this purpose.  I haven't
heard anything else on this.

There a two pthread packages that I know of at this time:

  Chris Provenzano's pthread package.  The source is included in
  libc-5.2.18.

  mtp@big.aa.net (Michael T. Peterson) PCthreads(tm).  I will not
  support this pthread package unless the full source becomes freely
  available.

Not that I am aware of.  I am officially part of ACT now and I am
pretty much in charge of the Linux port.  I have been working with
Chris Provenzano's pthread package, but will listen to any and all
arguments regarding the best pthread package to support.  Note that
the source must be freely available as there may be problems and/or
enhancements that need to be made.

If you have concerns and/or requests regarding the Linux port of GNAT,
please send email to report@gnat.com.
