Recent Activities in
High Performance Seismic Processing
Olin Johnson, University of Houston,
Speaker |
 Our ideas of 3-D processing have
changed due to new source- receiver geometries,
new processing architectures and new network
capabilities. We review such trends as vertical
cabling, parallel processing and online digital
libraries.
In this presentation, we present the
University of Houston's most recent efforts in
these areas. They include: |
*
The acquisition Of an IBM SP-2 with 64 processors
and an archival tape robot attached to VBNS,
the precursor to Internet 11.
* Installation of SEISPAC, Texaco Research's
3-D seismic processing system.
* Modification of UH's physical modeling tank
to allow 3-D vertical cable surveys.
* Interaction with the Society of Exploration
Geophysicists'
Research Committee to administer a large-scale,
on-line digital library of standardized modeling
data.
|
The digital library discussed here
was originally produced by the SEG Research
Committee and the Department of Energy. It
involved the generation of two very large data
sets (1.5 terabytes). DOE spent about 20 million
dollars creating the data using numerical
simulation of seismic data of two large 3-D
surveys.
One was over a salt dome and the
second was over a large overthrust.UH has
physical model data for the salt model as well
BIOGRAPHY
-----------------------------------------------------
Olin Johnson, Professor of Computer
Science, has been interested in high performance
computing since receiving his Ph.D. in numerical
analysis from the University of California at
Berkeley in 1968. His work on polynomial
preconditioning for conjugate gradient
calculations is widely cited and his work on
finite element methods has been used in textbooks
on spline approximations. He has worked with the
geophysics program at UH since 1980 specializing
in the computational aspects of 3-D seismic
processing.
For the last several years he has
worked in numerical visualization using X Windows
and Motif. |
