Lock issue when working at NERSC #94

Closed fjaviersanchez closed 10 months ago

fjaviersanchez commented 1 year ago

Hi everyone,

When executing TJPCov from my $HOME directory at Perlmutter I get a OS Error: 524 that had to do with the inability to lock files in the regular NERSC filesystem (I think it would also raise if working from /global/cfs/). Switching the line: https://github.com/LSSTDESC/TJPCov/blob/master/tjpcov/tools.py#L90 from

self.fp = open("./lockfile.lock", "wb")

to

self.fp = open("/tmp/lockfile.lock", "wb")

solves the problem for me at NERSC (I think that executing from $SCRATCH or pointing to $SCRATCH would also work). Is this a me problem or can anyone else reproduce this?

Thanks in advance!

@fjaviersanchez Thanks for pointing this out and sorry about the delay! I believe this lock is no longer necessary as we fixed the underlying issue that it was attempting to address. I will remove this and that should fix the issue.
