Jonas Jusélius @ HPC/UiT¶
My background is in quantum chemistry, but I have always been fascinated by computers. I have been a Linux user since 1995, and I worked as a system administrator throughout my studies. In my spare time I like to fly paragliders and eat good food.
Work¶
My main task is leading the development work in the SYMBIOSES project. Other tasks in the HPC-group include:
- System- and software architect
- Project management
- Advanced user support
- Parallel programming
- Program optimization
- System administration
Codes and programming¶
I have a keen interest in programming, and I know more than 20 programming languages. I have been a strong proponent for object-oriented design and techniques in scientific programming. More recently I have started to explore aspects of purely functional programming. My top 5 list of languages:
- Python - get things done
- Haskell - beauty and power
- Fortran - not as bad as you would think
- C/C++ - avoid if you can
- Lua, Clojure, Chapel - the new contenders
I have authored and co-authored a number of computer codes:
| SYMBIOSES | A tool for ecological impact assessment (main co-author) |
| MRCPP | Multi-Resolution Computation Program Package (main co-author) |
| GIMIC | Gauge-Including Magnetically Induced Currents (main author) |
| DAGE | Direct Approach to Gravitation and Electrostatics (co-author) |
| ARCS | Aromatic Ring Current Shieldings (main author) |
| HINDAROT | Hindered rotation of molecules trapped in rare-gas matrices (main author) |
| fiberview | Visualization of diffusion MRI data for brain fiber channels (main author) |
| getkw | User input parsing and validation library (main author) |
| Mantal | Django user registration and management app with read-write LDAP access (main author) |
| SpiderMan | A program for generating software listing pages from Lmod |
Science¶
I also work on some scientific projects:
- The SYMBIOSES project: A tool for ecological impact assessment
- A multi-wavelet based, fully grid adapted, massively parallel Poisson equation solver
- Magnetically induced currents in molecules
- Finite-element methods

Teaching¶
Occasionally I teach select subjects:
- Python
- Scientific programming techniques
- Quantum mechanics
- Inorganic chemistry
