ff2pp(vn8.5) on Cray(xcs) MONSooN2

Reported by: JuwonKim Owned by: um_support
Component: UM Model Keywords: ff2pp,bigend
Cc: Platform: Monsoon2
UM Version: 8.5


I have a 64bit field file which i need to change into a 32bit pp file in order to reduce the file size however ff2pp(vn8.5) doesn't work because there is no $UMDIR/vn8.5/cray/exec32/qxconvpp.
How can I do this?

Please try $UMDIR/bin/ff2pp

In this case, the pp file is little-endian format. I need big-endian format for iris.
Can I get this file as a big-endian format or convert to big-endian?

We are sill working through some system issues with the small execs, but in the meantime, you can byteswap with $UMDIR/bin/bigend ( include -32 for 32 but files)

$UMDIR/bin/bigend -32 xlqjza.pe59sep.pp xlqjza.pe59sep.pp.swap
