Query: Efficient algorithms for scheduling equal-length jobs with processing
  set restrictions on uniform parallel batch machines   We consider the problem of scheduling jobs with equal lengths on uniform
parallel batch machines with non-identical capacities where each job can only
be processed on a specified subset of machines called its processing set. For
the case of equal release times, we give efficient exact algorithms for various
objective functions. For the case of unequal release times, we give efficient
exact algorithms for minimizing makespan.
