Refactored I/O Emulation Framework To Enable Customized Mini-app Generation

Researchers at Sandia are actively investigating methods to develop better understanding of the I/O performance characteristics of SIERRA applications, both to provide guidance for current application deployments and to help prepare for migrations to future hardware and software platforms. The MiniIO C++ programming framework has recently been refactored to provide developers with the capability to rapidly generate targeted emulations of I/O behavior. This capability is enabled through an extensible class hierarchy, and one of the goals of the framework is to incorporate subclasses to form a catalog of these targeted mini-I/O applications. The framework provides base classes which implement I/O patterns commonly found in production applications, and various data storage options are available or planned. The framework will be documented in a forthcoming SAND report.
