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. -----Original Message----- From: Jens Axboe [mailto:axboe@xxxxxxxxx] Sent: Thursday, January 28, 2016 12:14 AM To: Ruvinsky, Konstantin; fio@xxxxxxxxxxxxxxx Subject: Re: FW: default value for random_generator On 01/27/2016 05:21 AM, Ruvinsky, Konstantin wrote: > Hi, > > In the description of random_generator=str in HowTo ( > http://git.kernel.dk/?p=fio.git;a=blob;f=HOWTO;h=7c24c1b74296aa33cdff9 > 7eca9458defd291b6ca;hb=HEAD ) is not written now what is its default value. $ 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? -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
