(I've hit "send" by mistake)
as I was saying, I'm working on some libraries that might make it into
next year's NPFL or FHPC (hoping that ICFP will take place in Europe
or surroundings).
I understand your concerns with HMatrix; it's a widespread and useful
library and it deserves an appropriate home.
Perhaps it's also time to think about a dedicated documentation site,
similar to that of accelerate (
http://www.acceleratehs.org/) ?
Kind regards,

Hi Dominic,
unfortunately I'm not able to submit a paper attend ICFP this year,
as much as I'd love to attend the NPFL and FHPC workshops.

Hi Marco,
I really intended this to be a home for “unbundling” hmatrix so that it is
easy for folks to contribute. At the moment, hmatrix-* is pretty much one
giant repo. I’d rather not add other stuff until this is complete. I haven’t
even had time to talk to Alberto Ruiz about this yet (but will do so now).
I’m not even clear how to move the existing projects to the new home.
I will certainly add you to the group and look forward to your contributions
to hmatrix itself :)
BTW I am chairing a workshop at ICFP this year: Numerical Programming in
Functional Languages (https://icfp18.sigplan.org/track/npfl-2018-papers).
Perhaps you would be interested in submitting a proposal?

Thank you Dominic for sharing this work :)
An industrial-strength ODE integrator suite like Sundials is certainly
a welcome addition for many people. Regarding the `haskell-numerics`
github organization ; such a general name sounds like it can
accommodate more projects than just HMatrix. I would be happy to be a
part of it, and I'm thinking to perhaps move the development of my old
PETSc bindings there.

Subject: [Numeric] New Version of hmatrix (more ODE solvers)
Message-ID: <2AC8F7D0-05AA-4DB7-8311-E7B664A893DF@steinitz.org>
Content-Type: text/plain; charset="utf-8"
I am pleased to announce a new version of hmatrix: 0.19.0.0.
This is not intended to be a breaking change but a lot of modules have been
modified to ensure that continuous integration (which has now been set up)
is green.
Support for SUNDIALS <https://computation.llnl.gov/projects/sundials> has
been added. It should be possible to replace Numeric.GSL.ODE with
Numeric.Sundials.ARKode.ODE and have your program work as before bearing in
mind that the methods and error control might differ (even for those with
the same names!).
The packages that comprise hmatrix are:
hmatrix
hmatrix-gsl
hmatrix-special
hmatrix-sparse
hmatrix-glpk
hmatrix-tests
hmatrix-sundials
I am planning to split these up into separate projects to make it easier for
contributors. To this end, I have created an hmatrix
<https://github.com/haskell-numerics> organisation in github. Please contact
me if you wish to become a member.
I strongly recommend anyone solving ODEs to look as hmatrix-sundials as the
underlying package provides many more methods, more documentation and more
diagnostic information (great when your 200 variable model fails). It is a
truism that any sufficiently sophisticated ODE solver package is a domain
specific language (I include the ODE solving part of GSL here). The current
interface both to GSL and to SUNDIALS is somewhat rudimentary but will
hopefully evovle to a nicer DSL (something at which Haskell excels).
