SCIENTIFIC COMPUTATION SEMINAR

                    -Thursday, May 11, 1989

Professor  Johnny Peterson from IBM Bergen Scientific center,
will speak on ``Parallel Seismic Wave Propagation''.

TIME:                 3:30  p.m.

ROOM:              DC 1304

ABSTRACT

Seismic  modelling  to produce realistic seismic traces
is  a computationally intensive problem. A 2D synthetic
wave propagation code using explicit finite differences
with absorbing boundary conditions has been implemented
on   an   Intel  Hypercube  with  32  processors.   The
algorithms  is highly parallel with good load balancing
between  processors  and  speed-up  proportional to the
number  of  processors being used. A vectorized version
of  the  code has been used to evaluate the performance
of the Intel IPSC/1-VX 5d vector hypercube.
