Optimization criteria for checkpoint placement

An on-line algorithm for checkpoint placement

Checkpointing is a common technique for reducing the time to recover from faults in computer systems. By saving intermediate states of programs in a reliable storage, checkpointing enables to reduce the lost processing time caused by faults. The length of the intervals between checkpoints affects the execution time of programs. Long intervals lead to long re-processing time, while too frequent ...

A Heuristic Checkpoint Placement Algorithm for Adaptive Application-Level Checkpointing

Checkpoint/rollback is an effective scheme for fault tolerance and has been widely used to reduce the overall execution time of long-running applications in case of faults. The locations of checkpoints in application programs are critical since the distance between two consecutive ones determines the checkpointing scheme’s sensitivity and overheads. If they are too far apart, applications might...

Optimization Strategies for Sensor and Actuator Placement

Well Placement Optimization Using Differential Evolution Algorithm

Determining the optimal location of wells with the aid of an automated search algorithm is a significant and difficult step in the reservoir development process. It is a computationally intensive task due to the large number of simulation runs required. Therefore,the key issue to such automatic optimization is development of algorithms that can find acceptable solutions with a minimum numbe...

Uncoded Placement Optimization for Coded Delivery

Existing coded caching schemes fail to simultaneously achieve efficient content placement for non-uniform file popularity and efficient content delivery in the presence of common requests, and hence may not achieve desirable average load under a non-uniform, possibly very skewed, popularity distribution. In addition, existing coded caching schemes usually require the splitting of a file into a ...
