FUJITSU Technical Computing Solution SCIGRESS

  • An integrated platform for computational chemistry to support the development of materials
  • Equipped with a rich variety of modeling functions, computational engines, and analysis functions
  • Highly expandable with the ability to plug-in a wide variety of computational programs
  • Can be used without having to designate a particular machine within a network by using a “network license”

An integrated platform that can flexibly work together with a wide variety of computational methods

High precision

New Hamiltonians (PDDG/NDDO method, RM1 method) have been added to 
the semiempirical molecular orbital engines “MO-G” and “MO-S”. These increase the precision of heat of formation computations by 25% compared to PM3 when using the PDDG/NDDO method, and by 48% compared to AM1 when using the RM1 method.
A function for interfacing with the “MOPAC2007” semiempirical molecular orbital method software that supports the high-precision density functional software “ADF”, “PHASE”, and the PM6 method has also been added.
These high-precision partner products can be used in SCIGRESS.

Increased speed

The speed and convergence of structural optimization using the "MO-G" and "MO-S" semiempirical molecular orbital methods has been increased up to a maximum of 6 times through the addition of the GDIIS*1 method.
Furthermore, efforts continue to be made in SCIGRESS to support multi-core CPUs and improve the efficiency of parallelization.

Effective utilization of parallel distributed computational resources

SCIGRESS is equipped with a job management function. This ensures maximal utilization of the computational resources you own by automatically allocating jobs to idle CPUs.
The new addition of network licenses makes it possible to execute high-speed parallel computations without knowing the location of a computer.


SCIGRESS employs a highly expandable API. This delivers integration not only with partner products "ADF" and "PHASE", but with other well-known computational programs such as "Gaussian", "GAMESS" and "LAMMPS".
We also have a service for porting any software you desire to SCIGRESS, so please feel free to contact us in this event.


The various modeling tools for creating molecular structures from small molecules to large molecules and crystal structures are shared within the platform, making it possible to operate a variety of application software from a unified GUI.

Increased efficiency using procedures

Multi-step procedures such as executing calculations using the more detailed density function method after structure optimization using the molecular orbital method can be easily edited and executed.
This speeds up the research and development process by improving the efficiency of work such as by allowing simulations and experiments to proceed in parallel.

Covers all aspects of leading edge research from building models to computation and analysis

Workspace (Model Builder/Result Viewer)

Workspace is a module for building molecules. These can be built easily simply by using the mouse. It also shows molecular orbitals, electrostatic potential energy maps, UV-Vis spectra, and IR spectra from the calculation results.

Spreadsheet (Automated Batch Computation GUI)

  • Spreadsheet makes it possible to use lists to manage the large amounts of compounds and computation results synthesized in a laboratory.
  • Automatic calculations can be executed on batches of multiple compounds by specifying in advance the properties you want to find.
  • Sorting, graphing, and linear regression of data can be performed easily. Data can be output in a format suitable for submitting journal papers.
  • This alleviates much of the effort involved in calculations.



Calculation Modules


This module is used for calculations such as the optimal structure of molecules using molecular mechanics methods.
