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
