I/O-Intensive Applications on Clusters


If you use our ORCA software to conduct your research, please cite our paper and software in your publications. We highly appreciate if you give us the credit.

The deatils on the ORCA framework can be found in our paper listed below:

J. Zhang, X.-F. Jiang, M. I. Alghamdi, M. Al Assaf, Y. Tian, X. Qin, and M, Qiu, “ORCA: An Offloading Framework for I/O-Intensive Applications on Clusters,” Proc. the 31th IEEE International Performance Computing and Communications Conference (IPCCC), Nov. 2012. [PDF]


This offloading library enables users easily applying offloading technology to either an existing or a newly developed I/O-intensive application with minor efforts. The library is RPC-based that it highlights the offloading semantics by a small number of interfaces. It suports C and C++ applications.
