Hi Stefan,
probably. Its 2 compute nodes and there are jobs running. Our epilogue script will drop the caches, at which point I indeed expect the warning to disappear. We have no time limit on these nodes though, so this can be a while. I was hoping there was an alternative to that, say, a user-level command that I could execute on the client without possibly affecting other users jobs.
Hello,
If you know the names of the files to flush from the cache (from
/proc/$PID/fd, lsof, batch job script, ...), you can use something like
https://github.com/tortay/cache-toys/blob/master/drop-from-pagecache.c
on the client.
See comments line 16 to 22 of the source code for caveats/limitations.
Loïc.
