I\'m 开发者_StackOverflowtrying to translate the important parts of OpenMPI\'s mpi.h to the D programming language so I can call it from D.(HTOD didn\'t work at all.)I can\'t wrap my head around the f
I\'m trying to use MPI with the D programming language.D fully supports the C ABI and can link with and call any C code.I\'ve done the obvious stuff and translated the MPI header to D.I then translate
I have a filesystem with a few hundred million files (several petabytes) and I want to get pretty much everything that stat would return and store it in some sort of database. Right now, we have an MP
