demeter
- Ebuilds: 2, Testing: 0.9.27 Description:
As of 2026-04-28 demeter uses sci-physics/xraylarch (Larch) as
its analysis backend. Upstream ifeffit
(github.com/newville/ifeffit) was deleted; demeter has
first-class Larch support via lib/Larch.pm, which drives a
larch_server XML-RPC daemon (shipped by xraylarch). Set
DEMETER_BACKEND=larch in the runtime environment to pick the
Larch path; some peripheral features still defer to Ifeffit per
upstream's todo.org "Larch v. Ifeffit problem areas", but the
common Athena/Artemis analysis path works.

ifeffit
- Ebuilds: 2, Testing: 1.2.11d Description:
As of 2026-04-23 the upstream GitHub repository
(github.com/newville/ifeffit) has been deleted; the remote-id
below is recorded for historical reference only and does not
resolve. The author's maintained successor is Larch, packaged
as sci-physics/xraylarch. This ebuild is masked in
profiles/package.mask; it remains in the tree as a revival
target (e.g. if a usable fork surfaces or a local Fortran
build is still needed by sci-physics/demeter).

oommf
- Ebuilds: 3, Testing: 2.1_alpha2 Description:
OOMMF is a project in the Applied and Computational Mathematics Division (ACMD) of ITL/NIST, in close cooperation with µMAG, aimed at developing portable, extensible public domain programs and tools for micromagnetics. This code forms a completely functional micromagnetics package, with the additional capability to be extended by other programmers so that people developing new code can build on the OOMMF foundation. OOMMF is written in C++, a widely-available, object-oriented language that can produce programs with good performance as well as extensibility. For portable user interfaces, we make use of Tcl/Tk so that OOMMF operates across a wide range of Unix, Windows, and MacOSX platforms. The main contributors to OOMMF are Mike Donahue, and Don Porter.
