Intel Solaris 5.7 validation

[Ramin Nikaeen <rnikaeen@jupiter.nal.utoronto.ca>]

Dear Colleagues,

I have successfully installed ns-allinone-2.1b6 (released 18-Jan-2000)
on an Intel-based pentium PC running Solaris 5.7 and NS runs 
fine.

However, during the validation phase the output of some of the 
tests in the following test-suites were different from the reference
outputs:

	webcache	energy			mcache
	wireless-lan	wireless-gridkeeper	wireless-lan-newnode
	WLtutorial	wireless-lan-aodv


I will be very thankful if someone can answer any of the
following questions for me:

1. When are/aren't the failed validation tests significant?
   If the failed tests are part of those facilities of
   the NS simulator that I am not using, then does that
   mean that I can assume there is nothing wrong with
   the simulator and just use it?! Specifically, I want
   to use NS to study buffer management and in particular
   RED and I might even wright my own "Buffer Management"
   algorithm. Can I just ignore the failed validattion tests?

2. Has anyone installed NS on Solaris running on Intel?!
   Have they had a similar problem?!

3. How can I figure out whether the problem is caused 
   because of "improper installation (ie. libraries,
   compiler [options], make, etc)" or because of bugs
   in NS?!

4. Can this be because of floating-point arithmetic?

I also tried downloading the current daily snapshot and
compiling it and validating it on February 1, 2000 and
I got the same result.

I have included detailed information as to the OS,
COMPILER, and MAKE facilities that I used and the
list of the error messages below if you would like
to look at.

I will be very thankful if you can give me some advice
