Well, the problem is well solved for FORTRAN. The FORTRAN compilers
for the Fujitsu VPP machines verctorize quite well. The FORTRAN
compilers for the Cray PVPs are not that league, but still acceptable.


But with C it is quite another story. No simple DO statements,
aliasing problems, etc. So I am very interested in how well your
compiler will do the job.
