Accelerating Improvements in HPC Application I/O Performance and Efficiency

SESSION: Emerging Technologies

EVENT TYPE: Emerging Technologies

TIME: 10:00AM - 5:30PM

ROOM:Booth 3547

ABSTRACT:
In most cases, parallel computing I/O comprises a complex dance between the application codes, the compute node based software including MPI and the underlying interconnects. Until now, the common practice in application programming has been to take the I/O interfaces as a given and to code to them, at some cost to the application in terms of performance. The proposed poster will provide application developers/programmers and the providers of open source middleware architectures and interfaces a basis for discussing whether there are classes of applications that can become higher performance, more efficient and use less power by implementing a new framework of I/O APIs and, possibly, protocols. The prospect is APIs focused on a specific class of applications may achieve significant improvements in I/O efficiency with minimal effort. The outcome of the discussions at SC13 and thereafter will provide direction to drive the work of the OpenFabrics Alliance going forward.
