Supercomputers generate vast amounts of data, typically organized into large directory hierarchies on parallel file systems. While the supercomputing applications are parallel, the tools used to process them requiring complete directory traversal, are typically serial. We present an algorithm framework and three fully distributed algorithms for traversing(More)
In the LANL's PaScalBB network I/O nodes carry data traffic between backend compute nodes and global scratch based file systems. An I/O node is normally equipped with one Infiniband Nic for backend traffic and one or more 10-Gigabit Ethernet Nics for parallel file system data traffic. With the growing deployment of multiple, multi-core processors in server(More)
