Re: [HTCondor-users] Submit Requirements and condor_qedit

[Joan Piles <jpiles@xxxxxxxxxxxxxxxx>]

Hi,

The idea of immutable attributes looks totally cool!

However, I also wonder what would happen (both with submit requirements 
and with immutable attributes when the attribute is evaluated at 
matchmaking:

> request_memory = TARGET.Memory

Would it be possible to still limit it somehow?

I guess we will introduce submit requirements to warn the users when 
they try to do something not allowed, but still rely on START 
expressions to enforce them reliably :)
