[Swift-devel] Re: [alcf-support #60887] Can Cobalt command-line bug on Eureka be fixed?

[Andrew Cherry]

Mike-

My initial reaction is that a fix would probably not be doable in the  
next few days, since it would almost certainly require scheduling  
downtime to bring Cobalt down, apply the fix, test, and restart.  But  
I'll ping the Cobalt folks to find out how feasible this would be.  My  
recollections from my previous investigation is that it would require  
changes to the cluster_system component as well as the launcher, so a  
shutdown wouldn't be avoidable.
