Re: [HTCondor-users] transform syntax to build complex ads possible?

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi Greg & TJ,

many thanks for your suggestions!

Unfortunately, it looks like, that the context available for the 
Negotiator/GROUP_SORT_EXPR is too constraint for re-writing it more 
modular-ly.

E.g., in variations of [1] we tried to brake up the nested 
ifthenelse()'s and merge them into the final string for GROUP_SORT_EXPR 
(unsure about the elvis chain). But the Negotiator falls back for all to 
the default 3.4e+38.
Probably the "intermediate" is{GROUP} ads are not available in the 
limited group sort context, or?

Cheers,
  Thomas

regexp("group_OTHER",AccountingGroup), GroupResourcesInUse/GroupQuota + 
4.0,undefined]
isOtherMcore   = [ifThenElse(AccountingGroup=?="group_OTHER.mcore" || 
regexp("group_OTHER.mcore",AccountingGroup), 
GroupResourcesInUse/GroupQuota + 4.0 * 0.8,undefined]
isOtherScore   = [ifThenElse(AccountingGroup=?="group_OTHER.score" || 
regexp("group_OTHER.score",AccountingGroup), 
GroupResourcesInUse/GroupQuota + 4.0 * 0.2,undefined]
isNoneEnd = [ifThenElse(AccountingGroup=?="<none>",3.4e+38, 3.4e+38)]

{eval_set_}GROUP_SORT_EXPR = strcat([isOps :? isBelle :? isOther :? 
isNoneEnd])
