Samara State Aerospace University (National Research University), Samara, Russia
Supercomputer “Sergey Korolev” (IBM BladeCenter HS22, 15TFlops, 272 processors/1184 cores, 4 graphical processors / 1720 cores)
HP cluster (HP ProLiant, 1.5TFlops, «Unicluster», GTK 4.2)
Compact supercomputer КС-ЭВМ 1(ROSATOM, Sarov, AMD, 1.1TFlops, 12 processors/144 cores)
VPS’s hosted on “Sergey Korolev” (VMware vSphere)
GRID'2012 ОИЯИ, Дубна 2
ANSYS - an engineering simulation software (durability analysis, thermal physics, fluid and gas dynamics)
LS-DYNA – multi-purpose finite element package (mechanics of solid and liquid bodies)
GRID'2012 ОИЯИ, Дубна 3
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

client site(web-browser, SVN-client)
web-server site (storing deployment settings,
fowarding commands to templet-server)
SVN- server (project repo)
templet-server (running TempletSDK console utility, sending SSH-commands to supercomputer)
supercomputer (running SSH-commands)
