OpenBSD vs SMP, Threading, and Concurrency, Ted Unangst

openbsd vs smp, threading, and concurrency

I will discuss the current status of kernel SMP support, the rthreads thread library, and relevant future developments. Over the years, we have accumulated several concurrency primitives in the kernel, causing some confusion amongst developers, so I will lay out the origin and correct usage for each. The talk is primarily targeted at the budding OpenBSD kernel developer, but I will also describe the end-user effects of each topic.

@67576856666478964567 of course not.. maybe you are a person that just read half news.. Openbsd has not those problems... the de raadt just said that maybe would be a problem but recently the developer team didn't find any back door inside the system. just read a little and use the system ( wish is awesome).. see ya-..

Somehow of every person who's using OpenBSD or advocates it seem paranoid when they talk for some reason, including Raadt himself!

There more of these videos i watch, the more I feel the need for OpenBSD!

Every time they open their mouths they're afraid a virus might try to pull off an immune overflow on their IS firewall and possibly infect their respiratory system.

Please read this

OpenBSD is NOT safe to use. The Mossad and FBI have infiltrated it with devs who are payed to put in backdoors.

Jason Wright was hacking on OpenBSD IPsec crypto code at the time the backdoor was alleged to have been added, and that he was pentesting Siemens SCADA systems at the time Stuxnet was being constructed and at the very same national nuclear research lab identified by the New York Times.

Coincidence? Hardly.

OpenBSD = FBI infiltration

OpenBSD is NOT safe.

not sure what is the conclusion?

could be a bit more clear

maybe I need to watch again

turn off hyperthreading?

[bootiack]

so more interesting, what about 8g ram?

is that an emo?
