Re: [Gems-users] Pausing/continuing Opal simulations

[Dan Gibson <degibson@xxxxxxxx>]

Your best option is to use magic instructions, since output is typically 
buffered and your timing could be quite off if you rely on printf() for 
simulation control. There is also a lot of overhead in glibc and 
elsewhere for I/O that is unnecessary if you just use magic instructions 
instead.
