Current Questions
Greg and Christina can't see this page anymore. Don't know why. Solution could be to put it in google docs.
Actually this seems more widespread and affects the archive in some way so it will probably get fixed.
output_destination and stdout/stderr
...
This is a change. I am not sure if it affects us adversely or not but can we unchange this?
ANSWER: from Greg "After some archeology, it turns out that the change so that a file transfer plugin requesting to transfer the whole sandbox no longer sees stdout/stderr is intentional, and was asked for by several users. The current workaround is to explicitly list the plugin in the stdout/stderr lines of the submit file, e.g."
output = nraorsync://some_location/stdout
error = nraorsync://some_location/stderr
This seems like it should work but my plugin produces errors. Probably my fault.
tokens and collector.locate
...
ANSWER: the starter has an exclude list and .job.ad is probably in it and maybe it is being access sooner or later than before. Greg will see if there is a better, first-class way to trigger transfers.

Did it change since 10.0? Can we still use getenv in DAGs or regular jobs?

ANSWER: Yes this is true. CHTC would like users to stop using getenv=true. There may be a knob to restore the old behavior.

DONE: We will use condor_transfer since it needs to be there anyway.DONE: check out docs and remove getenv=true
Installing version 23
I am looking at upgrading from version 10 to 23 LTS. I noticed that y'all have a repo RPM to install condor but it installs the Feature Release only. It doens't provide repos to install the LTS.
...
ANSWER: Greg will find it and get back to me.
DONE: https://research.cs.wisc.edu/htcondor/repo/23.0/el8/x86_64/release/
Virtual memory vs RSS
Looks like condor is reporting RSS but that may actually be virtual memory. At least according to Felipe's tests.
...
ANSWER: try using RESERVED_MEMORY=4096 (units are in Megabytes) instead of SLOT_TYPE_1=95% and put SLOT_TYPE_1=100% again.
