Hi,
In the description of random_generator=str in HowTo
( http://git.kernel.dk/?p=fio.git;a=blob;f=HOWTO;h=7c24c1b74296aa33cdff97eca9458defd291b6ca;hb=HEAD )
is not written now what is its default value.
Regards

$ fio --cmdhelp=random_generator
care to send a patch to add it to the HOWTO/man page?
random_generator: Type of random number generator to use
type: string (opt=bla)
default: tausworthe
valid values: tausworthe Strong Tausworthe generator
: lfsr Variable length LFSR
: tausworthe64 64-bit Tausworthe variant
Care to send a patch to update the HOWTO/man page?

Hi Jens,
Thanks for your answer. Sorry for delay - was OOO.
The patch is very simple: is necessary to add words ", this is the default value" after description of the tausworthe generator:
999 random_generator=str Fio supports the following engines for generating
1000 IO offsets for random IO:
1001
1002 tausworthe Strong 2^88 cycle random number generator,
this is the default value.
1003 lfsr Linear feedback shift register generator
1004 tausworthe64 Strong 64-bit 2^258 cycle random number
1005 generator
Could you please add it to one of your future commits, since I'm not familiar enough with patching?
Thank you.

Sure, I added a mention of that to the HOWTO and man page.
