Browser-based harnessing of voluntary computational power

Fabisiak T., Danilecki A

Foundations of Computing and Decision Sciences

2017

Vol. 42, No. 1

3--42

Computers connected to internet represent an immense computing power, mostly unused by their owners. One way to utilize this public resource is via world wide web, where users can share their resources using nothing more except their browsers. We survey the techniques employing the idea of browser-based voluntary computing (BBVC), discuss their commonalities, recognize recurring problems and their solutions and finally we describe a prototype implementation aiming at efficient mining of voluntary-contributed computing power.

Applying Message Logging to Support Fault-Tolerance of SOA Systems

Danilecki A, Hołenko M, Kobusińska A, Szychowiak M., Zierhoffer P

Foundations of Computing and Decision Sciences

2013

Vol. 38, No. 3

145-158

This paper addresses a problem of increasing fault-tolerance of service-oriented systems built of RESTful web services. To solve such a problem, rollback-recovery protocol is proposed. The protocol employs known rollback-recovery techniques, however, it modifies and specially adjusts them for specific characteristics of the SOA systems. The paper includes a proof of safety property of the proposed protocol.
