Application emulators

• Construction of two application emulators motivated by loosely synchronous adaptive applications and by data exploration and data fusion applications. An application emulator is a suite of programs that, when run, exhibits computational and data access patterns that resemble the patterns observed in a particular type of application.
• The irregular scientific application emulator will be designed to simulate the behavior of coupled adaptive unstructured mesh codes, integro-differential equations solvers and particle codes.
• The data fusion application emulator will be designed to 1) simulate data intensive applications that run on a single multiprocessor platform and 2) simulate an additional computational step where results from individual data intensive calculations are combined. The data fusion application emulator will emulate operations such as image segmentation, image registration and compositing. The emulator will carry out I/O to disk arrays. Application emulators will be validated by comparing performance (on current multiprocessor architectures) of application emulators with performance of full applications.

Options:

• The irregular scientific application emulator will be extended to simulate behavior of Monte Carlo, multipole and structured adaptive codes.
• The data fusion application emulator will be extended to take tertiary storage into account.
