Clark Street, Vermillion, SD 57069, USA. (Dated: November 19, 2019) Multireference electron correlation methods describe static and dynamical electron correlation in a balanced way, and therefore, can yield accurate and predictive results even when single-reference methods or multicon- figurational self-consistent field (MCSCF) theory fails. One of their most prominent applications in quantum chemistry is the exploration of potential energy surfaces (PES). This includes the optimization of molecular ge- ometries, such as equilibrium geometries and conical intersections, and on-the-fly photodynamics simulations; both depend heavily on the ability of the method to properly explore the PES. Since such applications require the nuclear gradients and derivative couplings, the availability of analytical nuclear gradients greatly improves the utility of quantum chemical methods. This review focuses on the developments and advances made in the past two decades. To motivate the readers, we first summarize the notable applications of multireference elec- tron correlation methods to mainstream chemistry, including geometry optimizations and on-the-fly dynamics. Subsequently, we review the analytical nuclear gradient and derivative coupling theories for these methods, and the software infrastructure that allows one to make use of these quantities in applications.

  • Perturbational Treatment of Spin-Orbit Coupling for Generally Applicable High-Level Multi-Reference Methods
    Perturbational treatment of spin-orbit coupling for generally applicable high-level multi-reference methods Sebastian Mai1, Thomas Müller2,a), Felix Plasser3, Philipp Marquetand1, Hans Lischka and Leticia González1 1Institute of Theoretical Chemistry, University of Vienna, Währinger Str. 17, 1090 Vienna, Austria 2Institute for Advanced Simulation, Jülich Supercomputing Centre, Forschungszentrum Jülich, 52425 Jülich, Germany 3Interdisciplinary Center for Scientific Computing, University of Heidelberg, Im Neuenheimer Feld 368, 69120 Heidelberg, Germany 4Department of Chemistry and Biochemistry, Texas Tech University, Lubbock, Texas 79409-1061, USA Abstract An efficient perturbational treatment of spin-orbit coupling within the framework of high-level multi-reference techniques has been implemented in the most recent version of the COLUMBUS quantum chemistry package, extending the existing fully variational two-component (2c) multi-reference configuration interaction singles and doubles (MRCISD) method. The proposed scheme follows related implementations of quasi-degenerate perturbation theory (QDPT) model space techniques. Our model space is built either from uncontracted, large-scale scalar relativistic MRCISD wavefunctions or based on the scalar-relativistic solutions of the linear-response-theory-based multi-configurational averaged quadratic coupled cluster method (LRT-MRAQCC). The latter approach allows for a consistent, approximatively size-consistent and size-extensive treatment of spin-orbit coupling. The approach is described in

  • A Case Study with Nwchem
    CONCURRENCY AND COMPUTATION: PRACTICE AND EXPERIENCE Concurrency Computat.: Pract. Exper. 2010; 00:1–17 Published online in Wiley InterScience (www.interscience.wiley.com). DOI: 10.1002/cpe Performance Characterization of Global Address Space Applications: A Case Study with NWChem Jeff R. Hammond∗, Sriram Krishnamoorthy+, Sameer Shende‡ Nichols A. Romero∗, Allen D. Malony‡ ∗ Argonne National Laboratory + Pacific Northwest National Laboratory ‡ University of Oregon SUMMARY The use of global address space languages and one-sided communication for complex applications is gaining attention in the parallel computing community. However, lack of good evaluative methods to observe multiple levels of performance makes it difficult to isolate the cause of performance deficiencies and to understand the fundamental limitations of system and application design for future improvement. NWChem is a popular computational chemistry package which depends on the Global Arrays / ARMCI suite for partitioned global address space functionality to deliver high-end molecular modeling capabilities. A workload characterization methodology was developed to support NWChem performance engineering on large-scale parallel platforms. The research involved both the integration of performance instrumentation and measurement in the NWChem software, as well as the analysis of one-sided communication performance in the context of NWChem workloads. Scaling studies were conducted for NWChem on Blue Gene/P and on two large-scale clusters using different generation Infiniband interconnects and x86 processors. The performance analysis and results show how subtle changes in the runtime parameters related to the communication subsystem could have significant impact on performance behavior. The tool has successfully identified several algorithmic bottlenecks which are already being tackled by computational chemists to improve NWChem performance.

  • Elda Rossi CINECA – Bologna (Italy) the Problem
    Q5cost A common data format for program interchange in the Quantum Chemistry domain Elda Rossi CINECA – Bologna (Italy) The problem The problem was driven by a common practice in the group: a scientific problem needs several programs to be solved: specific in-house codes written by some of the partners (FCI, CASDI, NEVPT, PROP, TouChain). open source or commercial programs used for producing the standard quantities (COLUMBUS, DALTON, MOLCAS, MOLPRO, GAMESS, …) Dalton Transform TouChain None of them shares the same data format FCI Tricky procedure Get all the programs Install them on the local computer Translate the data [email protected] - Bologna (Italy) The solution: a computi/llbing/collaborati ve Grid Each program remains “at home” Each program maintains its own proprietary data format Each program must understand a common data ftfithformat for interchange A set of “translation utilities” takes care of translating data from/to the proprietary formats and the common format A sort of “grid environment” makes programs communicate and exchange data through a single interface [email protected] - Bologna (Italy) The final vision Resources ()(mainly applications) geographically distributed on heterogeneous platforms (resource GRID !!!) A central (web) interface for accessing them A way to define the flowchart and to run it (workflow!!!) Dynamic control over the execution (steering) Data are collected in a (virtually) central repository [email protected] - Bologna (Italy) The first problem: Data Format One of the main challenges is a lack of community standards for data representation. Two main strategies: To develop translators that map one format to another. This requires n**2 translators, additional data formats requires 2n more translators (theoretically be very unscalable) Support the development a community standard for the field and develop translators towards the common formats.
