No check

[will-moore]

Just for testing, use --no-check to avoid connecting to IDR, so we can just focus on perf of getPlanes() on current server.

On idr-next: lots of parallel jobs causes problems - #55 (comment)
but running on a single thread doesn't - #55 (comment)

Let's use a small number parallel threads on just omeroreadwrite-1...

[wmoore@prod120-proxy ~]$ 
[wmoore@prod120-proxy ~]$ cat nodes
omeroreadonly-1

$ screen -dmS cache parallel --eta --sshloginfile nodes -a ids_idr0016.txt -j10 '/opt/omero/server/OMERO.server/bin/omero login -s localhost -u public -w public && /opt/omero/server/venv3/bin/python /uod/idr/metadata/idr-utils/scripts/check_pixels.py --render >> /tmp/render_20240131.log'

EDIT: after 14 mins, Blitz log shows gaps of no activity for several mins, e.g. 13:38:03 -> 13:40:01 when we'd expect rendering to be happening constantly...

Those UnknownLocalExceptions have more info when ex is raised

Error: RenderJpeg Image:2047046 24297 [Well H1, Field 5] exception ::Ice::UnknownLocalException
{
    unknown = ConnectionI.cpp:2052: Ice::ConnectTimeoutException:

}

But catching classes that do not inherit from BaseException is not allowed don't have any other info in that log.
No errors from today in Blitz log:

It seems that the --render script stopped at the last Error above (9 Errors in total).

[wmoore@prod120-omeroreadonly-1 ~]$ tail /tmp/render_20240131.log
...
168/2304 Render Image:2052601 24307 [Well N17, Field 6]
Error: RenderJpeg Image:2052601 24307 [Well N17, Field 6] catching classes that do not inherit from BaseException is not allowed

[wmoore@prod120-omeroreadonly-1 ~]$ grep Error /tmp/render_20240131.log | wc
      9     126     995

That would seem to correspond with the number of jobs running:

Computers / CPU cores / Max jobs to run
1:omeroreadonly-1 / 8 / 9

and is likely due to the fact that raising the Exception causes each job to stop after the first Error.

Total number of Images rendered before all jobs failed is

[wmoore@prod120-omeroreadonly-1 ~]$ grep "Render Image" /tmp/render_20240131.log | wc
   1332   10670   73367

Divide 1332 images between 9 jobs gives an average of 148 images per job before Error.
We can see that's pretty good estimate - actually around 166 for 8 jobs and 0 for one job:

Is this now at a useful state for adding to tests etc?
