There yet exist no truly parallel file systems. Those that make the claim fall short when it comes to providing adequate concurrent write performance at large scale. This limitation causes large usability headaches in HPC. Users need two major capabilities missing from current parallel file systems. One, they need low latency interac-tivity. Two, they need(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)
