	May be the problem is not related to MPI, but
to the memory allocation on the Cray T3D. I have found a severe BUG
on T3D using the Cray C++ compiler, which is related to the
allocation scheme for complexe structure, not being freed properly.
As CRay will not released the new version of the compiler for the T3D
but only for the T3E, I have to wait for the new Cray machine.
Maybe other people have also experience memory allocation and desallocation
problem on T3D ?
