SIGSEGV, segmentation fault
Posted: Tue Feb 14, 2006 4:19 am
Dear VASP users,
I have compiled VASP 4.6.26 on a P4 Linux cluster (8 cpus) using ifc 9.0 and mkl 8.0. This is the second 8 cpu cluster onto which I compile VASP and I used exactly the same options, compilers and libraries for both clusters. However, the new cluster is installed with RHEL 4 (corresponding to Fedora Core 3) while the "old" one is a RHL 7.2 (corresponding to RHEL 2.1). I am also using LAM-MPI.
On the recently installed cluster, when running VASP (serial but parallel gives the same kind of error), everything starts normally but finally VASP crashes with:
"forrtl: severe (174): SIGSEGV, segmentation fault occurred stack trace terminated abnormally."
The only thing written to the stdout is:
"vasp.4.6.26 15Dec04 complex
POSCAR found : 2 types and 6 ions
LDA part: xc-table for Pade appr. of Perdew
POSCAR, INCAR and KPOINTS ok, starting setup
FFT: planning ... 1
reading WAVECAR"
and the tail of the OUTCAR is:
"initial charge density was supplied:
charge density of overlapping atoms calculated
number of electron 44.0000000 magnetization
keeping initial charge density in first step
----------------------------------------------------------------------------------------------------
----
Maximum index for augmentation-charges 10845 (set IRDMAX)"
There is no other information...
I installed ifc and mkl as non-root AND as root: same result.
I also tried to recompile VASP with less agressive optimisation flags: again, same thing.
However, if I simply copy my 'vasp' executable file from my first cluster to the new one, everything works fine!
I don't understand at this point what is going on and would really appreciate your help with this.
With best regards,
Rudy C.
