Wenguang Wang's Research
I am a
Ph.D. candidate in Department of Computer Science, University of
Saskatchewan. My supervisor is Rick
Bunt. My research activities are rooted in the DISCUS research
group.
My general research interests are in the
design and performance evaluation of operating systems, storage and
file systems, database systems, and distributed systems, with
particular emphasis on storage systems support for large scale
systems. This study includes analyzing workload characteristics,
identifying the bottleneck of the storage system under large
configurations, self tuning the parameters of the system to achieve
best performance, adapting existing algorithms to systems with
large configurations, and designing new algorithms for better
performance.
In my Ph.D. dissertation research, I studied buffer cache
replacement and proposed and evaluated a new approach to managing
buffers in large scale systems. I studied the disk layout approaches
for storage servers and database systems, and proposed and evaluated a
new approach which is more robust than existing approaches. I studied
the tuning of buffer pool management in database systems, and proposed
and evaluated a self-tuning algorithm which automatically tunes the
system to achieve close-to-optimal performance.
