Dear Walker,

 

I post the file having the error message.

 

There is not the file of TEST_FAILURES.diff in parallel version.

 

I attatched the file of TEST_FAILURES.diff in silgle verion itanium-patched.

 

Take care.

Dear Lee,

Firstly did you apply the patch I sent several days ago to address hanging
when running in parallel? Did it work?

>I installed amber9 single version in intel itanium server called white box.
>After install, I runned testcase with make test.sander.QMMM.
>In crambin_md.out, I got strange messages as follow.

This is in serial yes?

>QMMM: WARNING!

Since this test case passes on other system I have tried I once again
suspect that this is a case of the compiler not doing what it is supposed
to. Can you please give me detailed specs of the machine so that I can try
to track this down.

For this I will need:

Operating system and version
Details of "cat /proc/cpuinfo"
Compiler version (use ifort -V if the intel compiler - I need the full
version number. E.g. 9.1.033)
Options passed to ./configure
A complete copy of crambin_md.out from the above test case.
The results of "echo $TESTsander" and "echo $DO_PARALLEL" in the same shell
in which you are running make test.sander.QMMM

Is this the only test case that fails? Can you do exactly the following...

cd $AMBERHOME/test/
make clean
make

Let all tests run to completion and then send me the file
$AMBERHOME/test/TEST_FAILURES.diff

Once I have these details I can try and reproduce the problem myself and see
if I can come up with yet another workaround...

All the best
Ross
