The benefit of migration in parallel evolutionary algorithms
Proceedings of the 12th annual conference on Genetic and evolutionary computation, 2010Parallelization is becoming a more and more important issue for solving difficult optimization problems. Various implementations of parallel evolutionary algorithms (EAs) have been applied in the past decades. Island models combine phases of independent evolution with migration where genetic information is spread out to neighbored islands.

Randomized Algorithms for Multiprocessor Page Migration
SIAM Journal on Computing, 1992The page migration problem is to manage a globally addressed shared memory in a multiprocessor system. Each physical page of memory is located at a given processor, and memory references to that page by other processors incur a cost proportional to the network distance.

Improved Algorithms for Dynamic Page Migration
2005The dynamic page migration problem [4] is defined in a distributed network of n mobile nodes sharing one indivisible memory page of size D. During runtime, the nodes can both access a unit of data from the page and move with a constant speed, thus changing the costs of communication.

Practical algorithms of geometrical migration
Proceedings of the XIII Internarional Conference on Ground Penetrating Radar, 2010Practical GPR survey schemes based on a geometrical migration algorithm are implemented and experimentally tested: (1) random GPR data collection from water surface along a tangled path and interpolation to a regular grid for bottom reconstruction; (2) double-pass B-scan with different antenna offset for estimation of the upper ground layer thickness ...

An Energy-Efficient Migration Algorithm for Virtual Machines to Reduce the Number of Migrations
2021It is critical to reduce electric energy consumed in information systems, especially servers in clusters to realize green society. By making a virtual machine migrate from a host server to a guest server, the energy consumption of the host server can be reduced since application processes on the virtual machine leave the host server. On the other hand,

Algorithms for Data Migration.
2022This thesis is concerned with the problem related to data storage and management. A large storage server consists of several hundreds of disks. To balance the load across disks, the system computes data layouts that are typically adjusted according to the workload. As workloads change over time, the system recomputes the data layout, and rearranges the

An Experimental Study of Data Migration Algorithms
2001The data migration problem is the problem ofc omputing a plan for moving data objects stored on devices in a network from one configuration to another. Load balancing or changing usage patterns might necessitate such a rearrangement ofda ta. In this paper, we consider the case where the objects are fixed-size and the network is complete.

A migration scheme for the genetic adaptive routing algorithm
SMC'98 Conference Proceedings. 1998 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.98CH36218), 2002This paper presents a string migration scheme for an adaptive network routing algorithm called a genetic routing algorithm which employs genetic operators to create alternative routes in a routing table. String migrations are employed usually in islands model of parallel or distributed genetic algorithms, which exchange strings among subpopulations to ...

An Energy-Efficient Algorithm for Virtual Machines to Migrate Considering Migration Time
2020It is critical to reduce electric energy consumed by servers in clusters to reduce carbon dioxide emission. Here, application processes issued by clients are performed on servers in clusters. In this paper, we take the migration approach that application processes on a server migrate to a guest server by using the live migration technologies of virtual
