dimensions the f90 MPI bindings should support (they are strongly typed, and the number of dimensions of choice arguments must be specified -- it cannot be arbitrary). The default is four. Note that even though increasing this value has essentially a linear effect on the code, the multiplier constant is fairly large (only a small number of functions have 2 choice buffers, so the exponential factor is relatively small). Increasing this value increases the amount of time f90 compilers will spend compiling src/mpi/f90/mpi.f90 (some compilers will crash if it is too big). This commit was SVN r5268.
