I have known Mark Baker since 1995 when he joined me at my research center in high
performance computing (NPAC) at Syracuse University. After he returned to
Portsmouth I have continued to interact with him in several different projects
including clustered computing, benchmarking and the use of Java in high
performance computing. It is clear from his resume that Mark is extremely active
in these important areas and indeed his work is growing in recognition and
importance.
As well as important research work, he has performed much service to the
community. This is illustrated by his leadership of the highly regarded
PEMCS benchmarking effort and his tireless work for the journal
Concurrency (and Computation):Practice and Experience which I edit.
He has edited 5 different special issues -- all on important topics. Although
I can not judge it so directly, he is also very active in TFCC -- the IEEE
task force on clustered computing.
Mark is an excellent teacher -- as I judge from the tutorials he has given --
including one on "Metacomputing: The Informal Supercomputer" which were part
of activities I led.

Mark has ny unreserved recommendation for a Lecturer position at Oxford.
I look forward to continuing to collaborate with him.
