To whom it may concern,

Chris Martin worked for myself and Professor James Allwright
in a Research Experience for Undergraduates program in computational 
physics at Syracuse University in the summer of 1993. 
His project was to take some sequential graph coloring algorithms and
programs and to parallelize them, with an existing parallel graph 
coloring algorithm as a guide.
He was asked to write the programs in two different parallel
languages -- Express Fortran (a MIMD message-passing language) and 
CM Fortran (a SIMD data-parallel language) -- and to test their performance
on two different parallel computers (an Intel iPSC/860 and a Thinking
Machines CM-5) for some sample graphs.

This required an understanding of the graph coloring algorithms,
the exisiting code, parallel computing concepts,
and the two specific parallel languages and computers.
In a very short period of time, Chris was able to familiarize himself
with the algorithms and the parallel programming aspects of the work, 
and to produce working programs and results with very little supervision.
He produced an impressive paper and poster on his work, and he will be
co-author on a paper on this work to be submitted to an academic journal.

Chris is very quick to pick up new concepts, is a responsible and 
enthusiastic worker, and a good programmer.
He is intelligent, amiable, polite, and a pleasure to work with. 
I believe he would do extremely well in graduate school and recommend 
him highly.
