Are there any inherent size limit for record length or matrix size/number of entries? I am generating a large 1-D complex*16 array which contains all non-zero items for a large linear equation matrix. The largest one I can get is about 2x10^9 items, or about 60GB (Lager than that the program runs but no output, although there is no error message either). Are these numbers reach the internal limits? If yes, is there anyway I can increase these limits? (The array is to be used in PARDISO which requires a 1-D array for non-zero entries). I am using Fortran Visual Composer XE 2011.
