Ramin> Dear Colleagues,

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

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

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


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

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

It does not necessarily hinder your progress.  Most likey it won't.

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

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

We have experienced some byte alignment problems with Solaris running
on Sparc machines.  We have fixed the problem for Solaris/Sparc, but
perhaps not for Intel.  Do you get core-dump when you run any of the
abovementioned tests?

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

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

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

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