[2019-02-10]  An update release, ELSI v2.2.0, is now available on the Download page.  The ELSI interface now can take arbitrarily distributed matrices as its input.  This release also adds a number of utility subroutines for geometry optimization and molecular dynamics calculations.  See the Changelog for a list of enhancements and fixes.

[2019-01-07]  ELSI developers participated in the Extended Software Development Workshop: Scaling Electronic Structure Applications, held in Dublin, Ireland from January 7-18, 2019.


2018

[2018-10-23]  An update release, ELSI v2.1.0, is now available on the Download page.  This release adds support for linear scaling density matrix purification algorithms in the NTPoly library.  Additional improvements are summarized in the Changelog.

[2018-08-17]  The ELSI Workshop “Solving or Circumventing Eigenvalue Problems in Electronic Structure Theory” was held in collaboration with MolSSI from August 15-17 in Richmond, VA, USA.  More information, including slides from the presentations given, may be found at the conference website.

[2018-08-07]  The NTPoly library was integrated with ELSI.  NTPoly is a massively parallel library for computing the functions of sparse matrices, enabling linear scaling density matrix purification methods in ELSI.

[2018-06-22]  An update release, ELSI v2.0.2, is now available on the Download page.  Bug fixes and known issues in this release may be found in the Changelog.  We welcome your feedback and suggestions, as always.

[2018-06-13]  An update release, ELSI v2.0.1 (we moved to the semantic versioning scheme), is now available on the Download page.  Bug fixes and known issues in this release may be found in the Changelog.

[2018-05-22]  We are pleased to announce the release of ELSI 2018.05 (release candidate; v2.0.0).  Source code and users’ guide of this release may be found on the Download page.  This release adds support for spin-polarized calculations and periodic calculations with multiple k-points.  Additional new features and improvements are summarized in the Changelog.  As we are working towards the final release of ELSI 2018.05, we look forward to your feedback and suggestions.

[2018-05-21]  An ELSI workshop is planned for summer 2018.  This meeting will be open to the community and is intended to foster discussion in computational linear algebra and strategies to address or circumvent the Kohn-Sham eigenvalue problem.  Stay tuned!

[2018-04-27]  We have opened up the ELSI GitLab server to the general public; anyone can now anonymously clone and pull the latest development branch of ELSI!  Feel free to contact us for an account if you would like to submit your own changes to ELSI.

[2018-02-05]  ELSI developers participated in the Electronic Structure Library Coding Workshop: ESL Demonstrator workshop held in Lausanne, Switzerland from February 5-16, 2018.  Integration into the ESL Bundle and the ESL Demonstrator, SIESTA support, and implementation of a CMake-based build system were initiated during this workshop.

[2018-01-01]  The first ELSI publication (ELSI: A Unified Software Interface for Kohn-Sham Electronic Structure Solvers) is official.


2017

[2017-10-22]  A brand-new version of PEXSI, PEXSI v1.0, was released.  In this update, the number of poles used by the pole expansion method can be reduced by a factor of 4.  New functionalities of this PEXSI release have been integrated into ELSI.

[2017-09-22]  The ELPA connector in ELSI was upgraded to the 2016.11.001 release.  Kernels written with AVX512 instructions were added in this update.

[2017-08-18]  Footage for the ELSI Connector Meeting 2017 has been uploaded to our new YouTube channel!  Our channel is located here, and the playlist for the meeting may be accessed here.

[2017-08-16]  The ELSI Connector Meeting 2017 was held at Duke University on August 16th, 2017.

[2017-07-10]  ELSI developers participated in the Electronic Structure Library Coding Workshop: Drivers workshop held in Trieste, Italy from July 10-21, 2017.  The implementation of spin channels and k-points in ELSI was initiated during this workshop.

[2017-05-31]  ELSI Interface 2017.05 was released today!

[2017-04-11]  The ELPA connector in ELSI was upgraded to the 2016.11.001.pre release.  The stability of ELPA and its performance on hybrid CPU/GPU and multi-core architectures are being continuously improved, thanks to the Max Planck Computing and Data Facility (MPCDF) and their collaborators.


2016

[2016-12-14]  A GitLab CI was set up to perform continuous integration on the ELSI development repository.

[2016-11-08]  A new version of PEXSI, v0.10.1, was released.  This update extends support to complex Hermitian Hamiltonian and overlap matrices.  New functionalities of this PEXSI release have been integrated into ELSI.

[2016-08-19] The ELSI Connector Meeting 2016 was held at University of California, Berkeley.  This meeting included the core participating teams of ELSI and its stakeholder groups.
