Hi Alain,

the minimal tests ran fine, except with the Intel Compiler with -O3. I get core dumps as well with some tests.

I will run the accuracy tests and see whether they report any problems.

best regards,
Samuel

Hello Samuel,

Some aggressive optimization options may produce unstable code and therefore abinit comes with an extensive set of test programs. Can you give some information about how your different builds behave with the "minimal" or "accuracy" test suite?

Kind regards,

Alain

Hi,

we are having trouble with abinit (abinis) results. They seem very unstable and differ a lot depending on the compiler used.

I used the 5.5.4 abinit version and 3 different compilers.
Intel 10.1 (10.1.015)
GNU 4.3.1
Sun Compiler (latest express release Sun Ceres Fortran 95 8.3 Linux_i386 2008/07/10)
