[Releases]

H2Lib 3.0

We are happy to announce the release 3.0 of our H2Lib package. Compared to its predecessor, the new release offers the following new features:

DH²-matrices for high-frequency Helmholtz problems,
extended GPGPU- and SIMD-accelerated boundary element quadrature and H²-GCA compression,
lowest-order Raviart-Thomas elements for Darcy's equation with matching domain-decomposition clustering strategies.

Of course this release also includes a number of bugfixes and improvements.

This release can be obtained from GitHub.

We are happy to announce the release 2.0 of our H2Lib package. Compared to its predecessor, the new release offers the following new features:

support for complex and single-precision types throughout the entire library,
application module for three-dimensional Helmholtz problems discretized by the boundary element method,
GPGPU-accelerated boundary element quadrature and H²-GCA compression,
application modules for two- and three-dimensional finite element discretizations,
domain-decomposition clustering strategy,
new H-matrix arithmetic functions,
new build configuration system separating system parameters and build options.

Of course this release also includes a number of bugfixes and improvements.

This release can be obtained from GitHub.

We are happy to announce the first release of our H2Lib package. The new library offers the following features:

data structures for clusters, blocks, low-rank matrices, H- and H²-matrices,
application modules for two- and three-dimensional boundary element discretizations of the Laplace equations,
compression schemes for non-local operators including ACA, HCA, GCA, and H²-GCA,
H-matrix arithmetic functions including truncated multiplication, inversion, and factorization,
H²-matrix arithmetic functions based on local low-rank updates,
H²-matrix compression algorithms.

This release can be obtained from GitHub.
