Re: [OMPI users] MPI_STARTALL doesn't compile with mpif90 and a multi-dimensional request array

Hi Jeff Thank you so much for taking the time to read and answer all my blurb. Yes, the Matlabish multidimensional arrays of Fortran90 provide convenient ways to refer to array sections, to avoid explicit calculation of address arithmetic, etc, but they can be quite annoying when all you want

Re: [OMPI users] self-messaging questions

Hi Jeff Thank you very much for your detailed answers. This is the type of information that is hard to find, even if you read "MPI The Complete Reference" over and over, highlighting and writing notes on the margins. Considering what you wrote, and the perhaps only marginal advantage of copying
