A blog about computer science, programming, and whatnot.
I'm Martin, and I'm currently a PhD student at IST Austria in
Bernd Bickel's group
working on computational design and fabrication of soft robots.
I have broad interests within computer science, including:
compilers and runtimes,
high performance computing,
and probably much more.
In computing at large I also enjoy
and thinking and writing about it all.
Outside computing, I appreciate
I have a technical blog in which I try to write on topics I care about.
Here's a list of other pages on this site.
Here's a list of projects I've done, ordered by date.
Object Deformation for Molding
1 Jul 2019
When molding objects with few mold pieces, a problem is that the casted model cannot
have any overhangs since the mold itself would be impossible to remove when the casted
piece is cured. In this project, I
adapted the ARAP deformation algorithm of libigl
to weight for this moldability constraint.
In collaboration with Bernd Bickel
git repository available.
Algorithms for Persistent Homology
20 Feb 2019
I did an experimental comparison of two variants of the well-known matrix reduction algorithm in computing persistent homology.
The algorithm computes the liveness of holes of a simplicial complex;
for the alpha complex this correspond to the holes that are created and filled by growing
balls of a radius around each point in a point cloud.
In collaboration with Herbert Edelsbrunner.
git repository is available, and continues to see some development.
Relaxed Scheduling of Disjoint-Set
4 Dec 2018
Investigated expected number of collisions in scheduling random Disjoint-Set operations, in collaboration with Dan Alistarh.
Schedulers can use a relaxed priority queue for ordering its tasks;
the relaxation makes out-of-order
Looking at a Disjoint-Set data structure, we want to know the expected number of collisions,
where the out-of-ordered popped operation has a dependency on another operation before it in the queue.
Writeup available, although in a rough state.
Master Thesis: Multithreaded-Aware Garbage Collector for Rust
13 Jun 2018
Master’s Thesis at Norwegian University of Science and Technology.
Implemented a tracing garbage collector for Rust, with emphasis on multithreaded use-cases.
Supervised by Magnus L. Hetland, and in collaboration with Dan Alistarh of IST Austria.
Both the git repo and the thesis are available.
