Lower Bounds for Scheduling on Identical Parallel Machines with Heads and Tails
2004
Annals of Operations Research
In this paper, we investigate new lower bounds for the P=r j ; q j =C max scheduling problem. ...
A new bin packing based lower bound, as well as several new lifting procedures are derived for this strongly N P-hard problem. ...
In particular, it arises as a strong relaxation of the Multiprocessor Flow Shop problem (Hoogeveen et al. ...

Invalidation-Based Protocols for Replicated Datastores
[article]
2021

pre-print
Based on this insight, we draw inspiration from the multiprocessor for high-performance, strongly consistent replication in the datacenter. ...
In other words, the common operating environment inside a datacenter closely resembles that of a multiprocessor. ...
However, if a non-tail node attempts
to serve a read for which it has seen a write message propagating downstream
from head to tail, but has not seen the acknowledgment propagating upstream,
then the tail ...

Flow Shop Scheduling
[chapter]
International Handbook on Information Systems
The type of factory layout in the general case -handled in Chapter 10 -is the job shop; the particular case where each job is processed on a set of machines in the same order is the flow shop. ...
For convenience, let us assume that any two consecutive tasks of the same job are to be processed on different machines. ...
The optimal value of a preemptive solution of the one machine problem is mLB2. The next lower bound tries to take into account the heads and tails of different operations in a more efficient way. ...
