Re: [HTCondor-users] Caching large executable on worker nodes

Thanks Michael! I stumbled over these talks as well after Don mentioned
the use of SQUID. It looks as if Condor has decided to go for the SQUID
solution from 8.4.0 on, right? But what is then the future of the other
concepts? Are they just feasibility studies? Or were they competitor
ideas that ultimately did not make it?

Maybe someone of the experts could comment on this - it might be
interesting for many people working on this kind of problem.

Thanks in advance,
