摘 要
An opportunistic computing system typically
employs replicas to obtain stable resources
from unreliable workers. Usually, lifting the
replication factor can increase the worker
reliability but oppositely decrease the efficiency
due to computation redundant. To address the
best replication factor, many brokers adopt the
unstable trial-and-error strategy. This paper
develops a new resource broker for performing
the prioritized malleable tasks over a pool of
volunteer workers. The new approach controls
the replication factor via the balancing on the
system metrics that are positively or negatively
related to the factor. With this balancing
technique, the broker can rapidly control the
replication factor to adaptive to the changing
workload and thereby improves the system
performance.
