that is most probably the reason why the current version is so slow.
It is really important to avoid the writting on disc to get a reasonable
In the directory
there is a file
There you can increase the buffer size for
to such a large value that the files are not written on disc.
Alternatively you could use a
file. I attach an example file. This would avoid the recompilation
if you have to change the buffer sizes.
And finally it is important that you use
and do NOT use
trace_off(1) or something like that
because this would force ADOL-C to write the files on disc.
Hope this helps. Otherwise just email again.
