Incorrect mpi results on Itanium

#1 Post by peterklaver » Fri Feb 10, 2006 2:39 pm

Hello everyone,

I'm trying to run VASP (4.6.26) on an Itanium-linux computer. The serial version seems to run fine (although I had to reduce the optimisation on radial.f90 to -O2), but the mpi version gives very wrong results for some calculations, even when everything is compiled with -O0. For other calculations the -O0 executable gives correct results.
Is anyone using the mpi version on Itanium-linux? Which compilers and BLAS versions are you using? I use ifort 9.0, mkl721, and the HP mpi in /contrib2/hpmpi. I've put input files for a testcase, along with my vasp.4.6 makefile and the correct and wrong OSZICAR output on

http://dutsm1078.stm.tudelft.nl/files.tar.gz

If someone is using the mpi version on Itanium, could you run these input files in parallel please and let me know the result?

kind greets,
Peter

Forget it, Martin Hilgeman from SGI helped me out already. It was some pesky little thing in mkl721 (undefined 'dlnu' internal mkl symbol). With mkl8 it works.
