Passing parts of an array to other routine
Hi, I have a code that is supposed to work as a parallel algorithm as well as as a single-CPU job, and one routine is for collecting data on a grid stored in arrays of the form a(-1:nx,-1:ny,-1:nz,nb) or v (4,-1:nx,-1:ny,-1:nz,nb) into one big array of the form atot(ndim, 0:nxtot-1,0:nytot-1,0:nztot-1,nbtot) in a ... 5 Dec 2009 08:31

C interop to popen
I am a bit confused by the following example, which tries to call the unix (linux) popen(), fgets(), pclose(). It works as I would expect when compiled by g95, but the gfortran compiled code hangs around the first fgets(), #0 0xb7fcd424 in __kernel_vsyscall () #1 0xb7f091e3 in read () from /lib/i686/cmov/li... 17 Dec 2009 04:55
Difference between passing a number and a variable to a subroutine
Hello everyone! I just found out that Fortran distinguishes between passing a variable and actual numbers to a subroutine. F.eks. writing integer, dimension(2) ddims ddims(1) = 64 ddims(2) = 64 CALL h5dread_f(dset1_id, H5T_NATIVE_DOUBLE, bufnew, ddims, error) works perfectly, but CALL h5dread_f(dset1_... 2 Dec 2009 07:36
