Re: [Condor-users] autoclusterattrs (fwd)

Steve -

I don't think autoclusters are the problem.  We've recently discovered an issue with Condor-G matching only once per resource ad is an issue with the matchlist caching (which is yet another mechanism that speeds up the matchmaking process in the "regular" case).  It is on our list to fix this with Condor-G matching.  Discovery of this bug is credited to our friends in Italy at INFN working on egee (thanks Francesco!).  For now, you can workaround the problem by putting the following into your negotiator's condor_config :
   NEGOTIATOR_MATCHLIST_CACHING = False
  (normally it defaults to true)
Then restart the negotiator.  Hopefully this will restore the ability to match a given resource multiple times per cycle (assuming you've set things up this way) until we get around to fixing the issue in the caching code.

hope this helps
Todd

How do you change the AutoClusterAttrs
I am in a situation where I am using Condor-G matchmaking
but somehow all the AutoClusterAttrs of all the jobs in the
queue are the same, and thus only one job per negotiation cycle
can get matched to any remote resource.
I know it is possible to set the attribute NEGOTIATE_ALL_JOBS_IN_CLUSTER
to get around this.. but I am wondering in general how do we
set the AutoClusterAttrs.. I thought this use to be in
the condor manual but I can't find autoclusterattrs anywhere in
the manual now.
