Query: stdchk: A Checkpoint Storage System for Desktop Grid Computing   Checkpointing is an indispensable technique to provide fault tolerance for
long-running high-throughput applications like those running on desktop grids.
This paper argues that a dedicated checkpoint storage system, optimized to
operate in these environments, can offer multiple benefits: reduce the load on
a traditional file system, offer high-performance through specialization, and,
finally, optimize data management by taking into account checkpoint application
semantics. Such a storage system can present a unifying abstraction to
checkpoint operations, while hiding the fact that there are no dedicated
resources to store the checkpoint data. We prototype stdchk, a checkpoint
storage system that uses scavenged disk space from participating desktops to
build a low-cost storage system, offering a traditional file system interface
for easy integration with applications. This paper presents the stdchk
architecture, key performance optimizations, support for incremental
checkpointing, and increased data availability. Our evaluation confirms that
the stdchk approach is viable in a desktop grid setting and offers a low cost
storage system with desirable performance characteristics: high write
throughput and reduced storage space and network effort to save checkpoint
images.
