Help needed regarding "asynchronous file I/O","Real time data packing" etc. to boost computational speeds.

Siddheshwar Chopra

Dear Firefly users,
I would be grateful if anyone could explain the use of "asynchronous file I/O","Real time data packing" and Dynamic load balancing, to boost the computation speeds. Actually I went through a ppt about Firefly where all these features when switched on, resulted in very high speeds (for a fullerene dimer). DLB seems okay to me, but others are not.
In the manual it says that asynchronous file I/O is by default OFF in Linux.. Why so? and why is it ON for Windows? Does option "ASYNC=2" seem better?
What is Realtime data packing and how to control it?

Thanks in advance,

Kind Regards,
