Dear Net Community,
I am looking for a position in the area of parallel computing R&D in an
industrial or academic environment. I would like to use my
experiences in parallel computing rather than working with sequential
machines.
My interests are computer architecture, multicomputer interconnection
networks/topologies, parallel operating systems, scheduling,
efficiency on massively parallel systems and specific applications
on parallel systems (e.g. graphics, robotics).
I finished my Ph.D. thesis ("A massively parallel multicomputer
system to solve decoupled problems") in december 1990, it is currently
under review. I built my own MIMD machine based on Transputers and
wrote system and application software (in parallel-C, Occam and a
little bit assembler). Therefore I know hardware and software aspects
of parallel computing.
A Speedup of 23.9 on 24 processors could be measured. Although
Transputers have only four links I used a star topology, where the
central master dynamically configures the connection it needs in that
moment. The scheduler uses a self-adjusting granularity policy to
deal with unbalanced load (task size variation 1 to 1000). The
reached speedup is highly independent from the problem. Simulations
show that this hardware and software concept seems to work efficiently
with up to 1000 processors. One application was implemented under the
Helios OS to compare the throughput with my own OS nucleus.
If you are able to offer a position in the area of parallel computing
or if you know where I could get further informations, please feel
free to contact me. You can reach me via e-mail, (paper) mail, fax or
telephone.
I also would like to hear opinions about employing a foreign
researcher (if you are from outside of Germany).
Thank you very much in advance.
Dieter Homeister
