TURBOMOLE 7.4 化學計算軟體

  • TURBOMOLE 7.4 化學計算軟體
  • 編號
  • 類別
    生化統計分析軟體
  • 介紹
    Turbomole被認為是進行HF,DFT,MP2計算最快最穩定的代碼之一。它的特色不是在於新方法和新功能,而在於解決如何用盡量短的時間和 盡量少的內存需求,快速、穩定地處理工業應用型的分子。特別是它獨有的RI-DFT方法,據稱可以較其它大多數DFT程序節省10倍的CPU時間,因此非 常適合於大分子計算或中等分子的重複性計算(如幾何優化)

It provides:
  • all standard and state of the art methods for ground state calculations (Hartree-Fock, DFT, MP2, CCSD(T), …)
    • very fast molecular and periodic DFT codes
    • very efficient Coupled-Cluster-F12 implementation
  • excited state calculations at different levels (full RPA, TDDFT, ADC(2), CC2, CIS(D), …)
  • geometry optimizations, transition state searches, molecular dynamics calculations
  • various properties and spectra (IR, UV/Vis, Raman, CD)
  • fast and reliable code, approximations like resolution of identity (RI) are used to speed-up the calculations without introducing uncontrollable or unkown errors
  • parallel version for almost all kind of jobs
  • free graphical user interface

Initially TURBOMOLE has been specially designed for UNIX workstations as well as PCs and efficiently exploits the capabilities of this type of hardware. Meanwhile, TURBOMOLE runs on almost all kinds of hardware and systems, from standard Windows or MacOS Notebooks up to massivley parallel supercomputers. Most users run TURBOMOLE on Linux PCs, either local multi-core systems or clusters. TURBOMOLE consists of a series of modules; their use is facilitated by various tools and a graphical user interface TmoleX. Almost all time consuming parts of TURBOMOLE are parallelized for SMP/multi-core systems and/or for clusters using standard MPI.

Outstanding features of TURBOMOLE

  • Low memory and disk space requirements by usage of direct and semi-direct algorithms with adjustable memory and disk space: Run larger applications on existing hardware.
  • Full use of all finite point groups (unique feature in Quantum Chemistry: exploit symmetry of all point groups like D5d, Oh, Ih,… get a speed up of up to 120 for Ih)
  • Efficient integral evaluation
  • Stable and accurate grids for numerical integration of DFT functionals
  • Various methods for ground and excited state calculations and properties
