Subject: Re: [OMPI users] ssh MPi and program tests
From: Francesco Pietra (chiendarret_at_[hidden])

With amd64 etch, intel compilers 10, and openmpi 1.2.6 I had no
problem in compiling amber10.

Having changed to amd64 lenny, amber10 did no more pass installation
tets. I was unable to recompile amber10.

I upgraded openmpi 10 1.3.1, which passed all its tests, but again was
unable to recompile amber10.

Now I have purged everything about intel (compilers and mkl) and I am
installing version 11. I'll recompile openmpi 1.3.1 on these. If
amber10 still refuses to compile, i'll abandon intel for gnu compilers
 and math libraries.

I'll come to your questions. There was no misprint in what I wrote but
at the moment i am unable to do better. All issues about ssh were
resolved. Actually, there was no issue. I created the issues and
apologize for that.

thanks
francesco
