Large-scaled experiment and research with high-performance computing(HPC)
- HPC(High Performance Computer/Computing) is the term representing the large
amount of calculation in the unit time, and it is used for the simulation
and visualization of the large-scaled weather and disaster prediction,
research of molecule and material, medical and life science such as genome
information analysis, analysis of noise, sound, and fluid(water, wind,
and heat), pre-experiment including collision experiment, physic experiment,
space science.
Next generation of the high-performance computer with the highest speed
process function in the world, K computer "K"
- Riken is currently processing the construction of the next generation high-performance
computer (K computer "K") in port island, Kobe city, Hyogo prefecture.
"K" has the 10 peta FLOPS level of performance which is equivalent
to four times of the highest speed in the world as of February, 2011. They
aim to run the first test in the world in 2012 when it is completed. In
addition, it is aimed to construct the medical industrial city with the
latest medical centers in the second area of port island where "K"
is located. Additionally, four universities such as Kobe university is
now under construction, and it is expected to be developed as the base
of academic research.
Launch of "Laboratory of high-performance computing on cloud services"
- FORUM8 has established "High-performance computing on cloud services
-Kobe laboratory" in the "Advanced computational science support
laboratory, Foundation for Computational Science(FOCUS)" constructed
near the next generation super computer "K" in April 2011. We
will provide the service using supercomputer which supports for more than
15 Tera-FLOPS (15 trillion calculations per second).
The research overview is scheduled to be the development and operational
support of software service which will effectively use the supercomputer
environment and large storage environment. We aim to improve the service
so that the next generation supercomputer "K" which will launch
from 2012 in future.

<Related information> High-performance computing on cloud services (Up&Coming '11 Fresh Green Issue)
Engineer's Studio(R) is an analysis program with Finite Element Method(FEM), developed in-house
from pre-processing, calculation engine, to post-processing. This program
allows various analysis including static analysis, dynamic analysis, and
eigen value analysis. It supports for material nonlinear models and geometric
nonlinear models. The structural analysis using beam elements, fiber elements,
and plate elements can be performed.
For this time, we have launched "Engineer's Studio(R) Cloud Service"
where the main calculation is supported by FOCUS high-performance computing(*1).
This allows the scale for analysis to be enlarged and the time taken for
analysis to be reduced in Engineer's Studio(R).
In this service, the data is automatically linked with FOCUS high-performance
computing by creating and registering them via the Internet. The final
result data is scheduled to be taken via web application, saved in a medium
and sent to the customers according to the situation. |
As the platform of FOCUS high-performance computing is Linux, the transfer
is currently in progress. The algorithm of main process will be same as
Windows version when the service starts, however, we will develop the optimized
algorithm for FOCUS high-performance computing to improve the performance.
Please look forward it!

Future development

- Added option for selecting the result data before analysis to get only
the required data from a number of analysis data.
| High-performance computing option, Analysis support service |
This service is an option of the existing Engineer's Studio(R) analysis
support service. Engineer's Studio(R) supports for nonlinear plate elements.
The problems such as calculation time or memory consumption are sometimes
occurred in large scale models. The high-performance computing allows the
reduction of calculation time and the improvement of analysis accuracy
by supporting precise model analysis. In the analysis of 300 seconds (30,000
steps at intervals of 1/100 seconds), which was measured in the 2011off
the Pacific coast of Tohoku Earthquake, known for "K-NET Tsukidate(MYG004)"
opened in Kyoshin network( K-NET), NIED, the computation time is reduced
using supercomputer. Moreover, as the seismic waveform which was measured
in the subsequent aftershock is also opened in that network, a number of
step analysis (More than 50,000 steps) can be rapidly performed with consideration
of effect of main shock and aftershock.

This service is for the simulation of noise production in general by locating
the sound source and for receiving sound in VR space.
The analysis process is performed by high-performance computer, this service
is very useful especially for the large-scaled data process.
<Related information> UC-win/Road Noise simulation option (Up&Coming '11 New Year Issue)
Features
Noise Simulation option consists of Pre-processor (for data input), main
processor (for simulation) and Post-processor (for presenting result).
- Preprocessor
Data entry process of the sound source arrangement, sound receiving surface
settings, analysis condition parameters settings is performed in VR-Studio(R).
- Main processor
The reflection and transmission on ground surface and model surface are
considered by setting the sound path.(The information that the judgment
of diffraction is performed described in the article of "UC-win/Road
Noise simulation option" in the previous issue is incorrect. The diffraction
is not considered.)
In the analysis process, the data can be separately processed between sound
source and sound path. The parallel computation is executed in supercomputer
using this feature to process large scale date efficiently in VR-Studio(R)
version.
- Post processor
Rich display options help you to capture the simulation results from various
viewpoints. In addition to contours and contour lines commonly used for
presenting the simulation results, the option also has a unique ability:
visualizing sound pressure level by grid or sphere shape.
Future development
- Development of parallelized algorithm perfect for the use of high-performance
computer
- Improvement of simulation result display
- Development of VR-Studio(R) noise simulation option
