–Portals Direct I/O ("PDIO") is a special-purpose middleware infrastructure for writing data from compute processor memory on Portals-enabled compute nodes to remote agents anywhere on the WAN in real-time. The prototype implementation provided a means for aggregation of outgoing data through multiple load-balanced routing daemons, end-to-end parallel data(More)
Indiana University provides powerful compute, storage, and network resources to a diverse local and national research community every day. IU's facilities have been used to support data-intensive applications ranging from digital humanities to computational biology.For this year's bandwidth challenge, several IU researchers will conduct experiments from the(More)
3 Abstract PSC has developed a prototype distributed file system infrastructure that vastly accelerates aggregated write bandwidth on large compute platforms. Write bandwidth, more than read bandwidth, is the dominant bottleneck in HPC I/O scenarios due to writing checkpoint data, visualization data and post-processing (multi-stage) data. We have prototyped(More)
