WAVECAR file is too large. What should we do?

#1 Post by user » Tue May 10, 2005 9:20 pm

Hi All,

We could not generate an output file which is larger than 2GB on most of the machines. Do we have any way to overcome this?

Can we do a non-collinear calculation from a collinear one without the WAVECAR file from the previous (collinear) run? (see: http://cms.mpi.univie.ac.at/vasp/vasp/node156.html )

Thanks.

ad 1)
most probably the maximum filesize is not limited by available physical disk space but by
file size limits given to each user. you have to change these limits accordingly,
eg by setting ulimit -f [limit]
(have a look at the manpages of your shell)
ad 2)
yes, of course you can start without a (collinear) WAVECAR, the approach suggested in the manual is to spare some computing time
