Hi Net,
Using gopher-WAIS I found the following document:

Chapter 4 : 4.3 Communicating in Parallel
4.3 Communicating in Parallel
... that says:
For solving differential equations, CM Fortran programs can access a li-
brary of stencil routines. These routines combine pipelined floating-point arithmetic with highly optimized grid communications, often in several directions at once. The communication patterns are customized to the vari-
ous stencil, or star, patterns of the finite difference discretizations of these equations. For example, the two-dimensional, five-point stencil routine gets data from four grid neighbors and performs four adds and five
multiplies; it achieves speeds considerably beyond those achieved by manual
coding of the same operations.
Where are those routines? How can I access them?
Please send any information you have on the subject.
