physics of dissipative processes (long-time calculations, intensive I/O)

theoretical mechanics, economics, engineering (multiple calculations with different parameters, optimization)

optics (computation intensive mesh methods)

GRID'2012 ОИЯИ, Дубна 4

lack of skills in parallel programming

obtaining access from SSAU authorities

low level design tools (absence of IDE)

the need of technical support

the application domain specialists face with HPC periodically

GRID'2012 ОИЯИ, Дубна 5

service user works with sequential code

service user works in convenient development environment

“one click” to run the source code in parallel on desired supercomputing environment

GRID'2012 ОИЯИ, Дубна 6

parallelization (TempletSDK)

version control system (Subversion)

secure remote access tools (SSH)

GRID'2012 ОИЯИ, Дубна 7

analogs: OpenMP, Cilk – code structured to achieve efficient parallelization

difference 1: the code structure exposes process-oriented model

difference 2: the structure is coded in DSL

difference 3: the user can simultaneously change source code and its DSL-model, we provide a preprocessor that synchronizes the changes
