N2 - This poster describes the development of a highly scalable application layer parallel I/O library (ASCEM-IO) for sci-entific applications.This library was envisioned to leverage our earlier I/O optimization experience to build a scalable general purpose parallel I/O capability for any application. The parallel I/O library provides a higher level API (Ap-plication Programming Interface) to read and write large scientific datasets in parallel at very large processor counts. Specifically, the goal is to take advantage of existing parallel I/O libraries, such as HDF5 which are being widely used by scientific applications and modify these algorithms to better scale on larger number of processors. This is accomplished by dividing the traditional I/O operations (read/write) into two phases, a communication phase and an I/O phase. Re-sults with a real application on the Cray XT/5 indicates sig-nificant performance improvement on large processor cores when compared to default HDF collective I/O operations.
