Question
A Metview session on Atos has run out of tmp space - how can I make it work?
The error message might look something like this:
/etc/ecmwf/ssd/ssd1/tmpdirs/xxx.34391055/mv.211486.xxx/config: No space left on device
Answer
A session on ECMWF's Atos HPC interactive nodes provides a very fast temporary disk, but with little space on it. There are two solutions:
1) use the ecinteractive tool to log onto the HPC - this allows you to specify a larger (but still limited) amount of temporary disk space, e.g.
ecinteractive -s40GB
2) set SCRATCHDIR to be the temporary disk for this session before you start Metview:
export TMPDIR=$SCRATCHDIR
