Background
I have moved between
academia and industry seven times in my career and was most recently
the chief architect for the high-end server division of Sun
Microsystems, USA. I got my interest in parallel computers as a
visiting researcher at Dataflow group at MIT in the early 80s. That
interest was expanded at the Ericsson Computer Science Lab and led to
the Cache-Only Memory Architecture work (and its brain-dead acronym
COMA) at the Swedish Institute of Computer Science (SICS). I have
also worked with fault-tolerant CPU designs at Ericsson and software
tools for programmers at Rogue Wave Software Inc.
Research focus
I started the computer architecture research group
UART
at Uppsala.
Our research centers around new efficient
performance and power analysis techniques, as well as optimizations and tools built upon the insight they create.
We also work on new fast and power-efficient solutions for building computer systems of tomorrow.
The work is in part financed by
UPMARC
research center financed from the Swedish basic research (VR). UPMARC spans several research groups at the IT department
(press release from VR).
Startup
I founded the startup company Acumem 2006. Based on UART research
results we have developed a new technique for analyzing the execution of
applications and suggest ways to improve their performance.
Acumem was acquired by Rogue Wave Software in September 2010
(See article) .
Teaching
I am responsible for the advanced course in computer
architecture
"Advanced Computer Architecture"
Other
interests
Music: I
play chamber music (I play viola and cello) and have been a member of
the Heisenberg String Quartet (it is not possible to play a tone with
the right pitch
and the
right timing simultaneously)
since 1991 and the Fjord Clarinet Quintet since 2012. I belong to the
Mazer String
Quartet Society and the
Amateur Chamber
Music Players (ACMP).
Sailing: During
the summer I sail my 42 foot red
S-30
sailboat "
Cayenne".
Skiing: During the
winter I burn
all the fat I
gathere during the summer's
sailing in my preparation for the 55 mile ski race
Vasaloppet.
