M.S. Paper Title: Towards Scale-Checkable Systems

Abstract:
Is scale a friend or a foe? On the positive side, scale surpasses the
limit of a single machine in meeting user's increasing demands of
computing and storage, leading to many developments of "cloud-scale"
distributed systems. On the negative side, scale creates new
development and deployment issues; First, developers must ensure that
their algorithms and protocol designs are scalable, however, until
real deployment takes place, unexpected bottlenecks in the actual
implementations are often unforeseen. Second, the common practice of
debugging scalability in large clusters is complex, costly, time
consuming and is not ideal in times where continuous integration and
deployment are priorities. We present ScaleCheck, an approach for
discovering scalability bugs and for democratizing large-scale
testing. ScaleCheck employs a program analysis technique, for finding
potential causes of scalability bugs, and a series of colocation
techniques, for testing implementation code at real scales but doing
so on just a commodity PC. ScaleCheck has been integrated to several
large-scale storage systems, Cassandra, HDFS, Riak, and Voldemort, and
successfully exposed known and unknown scalability bugs, up to
512-node scale on a 16-core PC.

Cesar's advisor is Prof. Haryadi Gunawi
