Abstract
Three programs of the free surface flows solvers family are analysed in
view of parallelism. A short description of their main features is done,
with emphasis on the numerical methods used: finite elements with an
E.B.E. (Element By Element) implementation. The analysis of the
computational effort on scalar or vector machines is then carried out.
Eventually, several strategies of parallelism are tested on different
machines and compared. The results show that fine grain parallelism
and matrix-vector decomposition can be efficient but only with a small
number of processors, and with a maximum t
