LaTex doc I wrote for upstream:

%\label{param:GroupSortExpr}
%\item[\Macro{GROUP\_SORT\_EXPR}]
%  A classad expression which evaluates to a numeric value that is used
%  to sort accounting groups to determine which order they negotiate in.
%  The classad expression for \Macro{GROUP\_SORT\_EXPR} may involve any of
%  the following:
%  \begin{itemize}
%      \item AccountingGroup -- the name of the accounting group
%      \item GroupQuota -- the resource quota assigned to the group for the current negotiation cycle
%      \item GroupResourcesAllocated -- the resources allocated to this group by the HGQ algorithm
%      \item GroupResourcesInUse -- the resources currently in use by jobs associated with this group
%  \end{itemize}
%  An example group sorting expression that causes the root group (``<none>'') to always negotiate 
%  last, and other groups to negotiate in order of quota-based starvation:
%\begin{verbatim}
%GROUP_SORT_EXPR = ifThenElse(AccountingGroup=?="<none>", 3.4e+38,
%  ifThenElse(GroupQuota > 0, GroupResourcesInUse/GroupQuota, 3.3e+38))
%\end{verbatim}
%  If an expression fails to evaluate to a numeric value for a group, then
%  that group's sorting value will default to FLT\_MAX (3.40282e+38).
%  GROUP\_SORT\_EXPR defaults to the backward compatible starvation ratio:

%\end{verbatim}

Plain text:

GROUP SORT EXPR A classad expression which evaluates to a numeric
value that is used to sort accounting groups to determine which order they
negotiate in. The classad expression for GROUP SORT EXPR may involve
any of the following:
• AccountingGroup – the name of the accounting group
• GroupQuota – the resource quota assigned to the group for the current
negotiation cycle
• GroupResourcesAllocated – the resources allocated to this group by the
HGQ algorithm
• GroupResourcesInUse – the resources currently in use by jobs associated
with this group
An example group sorting expression that causes the root group (“¡none¿”) to
always negotiate last, and other groups to negotiate in order of quota-based
starvation:
GROUP_SORT_EXPR = ifThenElse(AccountingGroup=?="<none>", 3.4e+38,
ifThenElse(GroupQuota > 0, GroupResourcesInUse/GroupQuota, 3.3e+38))
If an expression fails to evaluate to a numeric value for a group, then that group’s
sorting value will default to FLT MAX (3.40282e+38). GROUP SORT EXPR
defaults to the backward compatible starvation ratio:
GROUP_SORT_EXPR = ifThenElse(GroupResourcesAllocated>0.0,
GroupResourcesInUse/GroupResourcesAllocated, 3.40282e+38)

Some off the text is missing, not sure if it is a problem though. But certainly there should not be \Macro{GROUP\_SORT\_EXPR} but just GROUP_SORT_EXPR.

For some reason underscores are not copied correctly in Comment 5, so here it is again:

GROUP_SORT_EXPR
A classad expression which evaluates to a numeric value that is used to sort
accounting groups to determine which order they negotiate in. The classad
expression for GROUP_SORT_EXPR may involve any of the following:
– AccountingGroup – the name of the accounting group
– GroupQuota – the resource quota assigned to the group for the cur-
rent negotiation cycle
– GroupResourcesAllocated – the resources allocated to this group by
the HGQ algorithm
– GroupResourcesInUse – the resources currently in use by jobs asso-
ciated with this group
An example group sorting expression that causes the root group (“¡none¿”)
to always negotiate last, and other groups to negotiate in order of quota-
based starvation:
GROUP_SORT_EXPR = ifThenElse(AccountingGroup=?="<none>", 3.4e+38,
ifThenElse(GroupQuota > 0, GroupResourcesInUse/GroupQuota, 3.3e+38))
If an expression fails to evaluate to a numeric value for a group, then that
group’s sorting value will default to FLT_MAX (3.40282e+38). GROUP_SORT_EXPR
defaults to the backward compatible starvation ratio:
GROUP_SORT_EXPR = ifThenElse(GroupResourcesAllocated>0.0,
GroupResourcesInUse/GroupResourcesAllocated, 3.40282e+38)
