WRITECAR with ACCESS='STREAM' in OPEN command???
Posted: Tue Oct 15, 2013 5:19 pm
To whom may help,
Anyone used the option ACCESS='SREAM' in OPEN comand of "fileio.F" for speeding up the time to write the binary WAVECAR in HD?.
I am working with VASP(5.2) and the option ACCESS='DIRECT' is very slow for my system. I know that my cluster can write the binary files faster than VASP is doing now.
By other hand, ifort uses to have switch off the option "buffered_io". Anyone know if this is so critical to slowing down the recording binary io files in VASP?
I wouldn't like to change these options and recompile without have some advisory.
Thanks for any comment.
