Dear All,

When I run a job (32 atom Super Cell with 6x6x4, Gama K-mesh) in IBM power5 (OS:-AIX) compiled in serial mode, I got this error:
"LDA part: xc-table for Ceperly-Alder, standard interpolation
POSCAR, INCAR and KPOINTS ok, starting setup
WARNING: wrap around errors must be expected
1525-108 Error encountered while attempting to allocate a data object. The program will stop."
So I recompile with, " FFLAGS = -O3 -qarch=pwr5 -bmaxdata:0x80000000" in the makefile in vas.4.lib and
"OFLAG = -O3 -qarch=pwr5 -bmaxdata:0x80000000"
in the makefile in vasp.4.6. Still I am getting the error mentioned above.
But for 16 atom supercell it is working.
I need help.
With Regards,
Saurabh ..

most probably, you do not have enough memory to run that job.
To check whether the crash really is due to the memory, please
1) either run vasp parallel, this distributes the load
2) try to reduce the required memory for testing (either by reducing the number of k-points, or by decreasing PREC)
