We are currently in the process of converting the website to the new design. Some pages, like this one, are still broken. We appreciate your patience.
Got it. As noted, it's a vague memory from about 2003, NT 4 or Win 2k. It's also possible that on…

My suspicion is that choice of 4k/64k/2mb (Windows also allows 2mb pages nowadays) as a page size …
Yes, to be more specific, I am talking about "free" access to thread local storage. Every platfor…
The problem is not the register file, it's the work units. For example, the CPU that we're using …

I was under the impression there was more than 1 SIMD register set you could work with. If you cou…
You might want to try measuring the performance of TLS on those platforms.
I don't have a Windows machine handy, but last time I worked in this area, the page size was 64kB…
Decrementing semaphore happens only on WaitForsingleObject function call. If InterlockedCompareExc…

Yes, I understand, but if a thread fails to get an entry, now, it will also decrement the semaphor…
Hey guys, I figured it out. For those who got the same bug. On the GameOutputSound function, I was…
Yes, but they will try to do it and fail. That's why we use InterlockedCompareExchange instructio…

You're right of course. If the hardware resource doing SIMD operation X is busy, the other hyperth…

This is very cool. I wish Sony would open Native SDK for Vita for everybody, not just the managed …
You can look at this a lot like the port pressure stuff we were doing with IACA. With HyperThread…
The point here is that the only possible way to actually have what you're talking about work is if…
In theory, as long as the SIMD unit executes only one hyperthread's stuff at a time it'll be as fa…

Good video. I liked the "juggling razorblades" analogy.
Yep, it makes sense and I agree it's the better option. I was initially thinking the implementatio…
