Hi Ethan, Thanks for your answer!

I run client/mtt with debug model, and found mtt script exited in following code section of lib/MTT/Module.pm.

32 my $str = "require $module";
33 Debug("Evaluating: $str\n");
34 my $check = eval $str;

When require error occured, $str was set to "MTT::Test::Specify::Simple
Simple". This is not a valid Perl module, so mtt failed. I had no time to probe why/where such value was got. I just modified Module.pm to work around the issue.

[root@host MTT]# !diff
diff primary/Module.pm ./lib/MTT/Module.pm
31a32,38
> if ($module =~ m/Simple/)
> {
> if (length($module) > 26)
> {
> ($module) = $module =~ m/(.*::Simple)/;
> }
> }

With this workaround, $str was changed back to "MTT::Test::Specify::Simple", and mtt script could continue. Ater all the tests finished, I found some MTT cases failed. For those failed cases, who will probe it? Or how can I probe them? Here list one section that returned error.

Re: [MTT users] MTT fail to require MTT::Test::Specify::Simple

It is odd that a "require" failed like this in the Test Run
phase. I would have expected an earlier "require" to fail
(e.g., in the MPI Install phase). I've never run MTT as root
before. Does root have read-access to Specify/Simple.pm? If
not, can you do the below command in the top-level MTT
directory?

 $ chmod -R a+r ./lib

FWIW, I was able to get a simple "require" to fail by
tweaking read permissions:

 $ echo "package Foo; 1;" > Foo.pm
 $ perl -e 'require Foo;'
 $ ls -l Foo.pm
 -rw-r--r--    1 em162155 staff 16 May 12 10:29 Foo.pm

Remove read permissions:

 $ chmod a-r Foo.pm
 Can't locate Foo.pm in @INC (@INC contains: /ws/ompi-tools/lib/perl5/5.8.8 /usr/perl5/5.8.4/lib/sun4-solaris-64int /usr/perl5/5.8.4/lib /usr/perl5/site_perl/5.8.4/sun4-solaris-64int /usr/perl5/site_perl/5.8.4 /usr/perl5/site_perl /usr/perl5/vendor_perl/5.8.4/sun4-solaris-64int /usr/perl5/vendor_perl/5.8.4 /usr/perl5/vendor_perl .) at -e line 1.
