I'm using NetCDF 4.2 with Fortran90 (using intel compiler on a nehalem system) and the memory seems to be related to the buffers of each file. But the memory use keeps growing even when the files are closed and I open new ones
I ended up writing a script around my fortran code to call it several times (only working on 150 files at a time) but this is rather annoying.
Any suggestion ?
You can ask this question in the newsgroup comp.lang.fortran (https://groups.google.com/forum/?hl=de&fromgroups#!forum/comp.lang.fortran), there are many very competent programmers.
We found a solution: creating the file with the option NF90_SHARE :
nf90_create(ncfile, NF90_SHARE, ncid)
The problem was when creating the files.
The NF90_SHARE option, however, only works with NetCDF 3 format ... So I think that the problem remains
I'm assuming a Linux environment - you might want to consider looking at the valgrind suite.
$ valgrind --tool=memcheck programname arguments
Will get you information on where memory leaks are occurring.
