(NUSO) in two different groups:

(a) Data Compression:
As part of the diploma theses I developed a software prototype
for data compression of CFD (computational fluid dynamics)
simulation results. From the bottom up I developed a command
line tool to read files based on the ADF and HDF5 file format. I
modified existing algorithms and combined them with new
developed algorithms to make the compression most efficient in
terms of compression rate and speed. To analyze the
compressed files I developed a tool to compare and plot the
relevant results.
Besides working in the data compression team I was also
responsible for the system administration of the IT infrastructure
in the NUSO department.

(b) AMG:
As part of the AMG (algebraic multi grid) team I was responsible
to evaluate, analyze and
reimplement time critical components of the parallel SAMG
software library. Within a European financed project of highperformance- computing I was testing components of the SAMG library on state-of-the-art platforms like multi GPU’s (GMGPU), vector processors and computer clusters of multi- and many-core processors with up to 128 cores.

In cooperation with the Max-Planck-Institute I was responsible for
the first level support of the product library HLIBpro, developed
by the Max-Planck-Institute. I had to license, port and benchmark
customer’s datasets to accomplish the integration of HILBpro into
our customers systems.

During the apprentice ship I created, maintained and later ported
the institutes websites to a CMS system.
As a scientific programmer I developed a parallel version of an
analysis tool for an ion implanter of the IBNI and ported it to the
JUMP supercomputer. Also I developed an analysis tool to read,
plot and archive (into microsoft excel files) the results of a particle
counter from the Axcelis NV8250 ion implanter
