This may be stupid, but could you not implement a Hawkeye script which populated
a ClassAd variable -- "InsideHolidayTime" or similar --
with a TRUE or FALSE
value depending on the current day of the year, and then refer to that variable
in the batch node's START _expression_?
[ I've already attempting something similar here: I have a requirement that jobs
submitted by members of a specific research group get priority access to
Condor batch servers that they own.
I've implemented this by writing a Hawkeye script that populates the ClassAd
variable "DoC_Priority_Users" with a list of usernames who should receive
preferential treatment, and seting the RANK _expression_ to read:
RANK = stringListMember(TARGET.Owner, MY.DoC_Priority_Users)
(stringListMember returns a boolean value, which is coerced into an integer
depending on the result of the _expression_; TRUE is mapped to 1, FALSE is
mapped to 0. As higher ranks mean higher priority, this should produce
the
desired weighting.)
Unfortunately, I haven't been able to verify that this is having the desired
effect -- this research group are far and away the biggest user of our Condor
pool! -- but I _think_ it's working.. ]
Cheers,

This one is easy. Take a look at the FAQ section of the Condor Manual,
specifically the FAQ "How do I configure Codnor to only run jobs at
night?", online at
http://tinyurl.com/64lxjo> and all the day during week end
Also easy, and the example included in the manual shows how to do
that... just take a peek at the URL i gave above...

Ouch. Holidays could be a little more tricky. What would be sweet is
if Condor's ClassAds implementation had a function to convert the epoch
time [e.g. output from time()] into a month/day/year representation,
like formatTime() as specified in the ClassAd Language reference. But
alas, formatTime() is not implemented. I will add that to the wish
list. In the meantime, anyone else have a good idea for how to
handle
holidays in a Condor scheduling policy?
