I have an issue in Fortran 90. I have a user-defined type, and when I call one of the MPI subroutines the data looks to be passed by value (not address, as I thought it should). The output arguments
What is the best way to scatter a Fortran 90 matrix by its rows rather than columns?That is, let\'s say I have a matrix a(4,50) and I want to MPI_SCATTER it onto two 开发者_StackOverflowprocesses wher
what is a good hashtable implementation for C? I need to use it 开发者_开发知识库with mpicc compiler. Delete function is not necessary.The one in glib is very nice. Not sure if it\'s too large and/or

I am trying to implement bitonic sorting using MPI for 2^n processors. I would like to use an n-dimensional hypercube to do so for convenience. Using MPI_Cart_Create I can crea开发者_StackOverflowte
Can someone elaborate the differ开发者_如何学Cences between the OpenMPI and MPICH implementations of MPI ?
I am looking for the best way of extracting a 2D sub-matrix from a larger 2-D submatrix. That is. If I have a matrix with 1 ghost point on each edge, I want to extract t开发者_如何学运维he interior ma
Sorry I cannot post any source code... I have a code running a master/slave red-black algorithm for a G.S. solver. In the simple case, the matrix is split into 4 evenly sized computational pieces. Th
I am a bit confused about this. If you\'re building a distributed application, which in some cases may perform parallel operations (although not necessarily mathematical), should you use ASIO or somet
