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…

I was wondering if it is possible to combine HT with SIMD. They are different types of parallelism…
Hey guys. I've got a bug on the code, after to watch the video "Day 012 - Platform-independent Sou…

So I recently got access to a PS Vita Dev Kit through the PlayStation First program where they giv…
Makes sense. I guess I'm more curious about there being some OS magic in between releasing semapho…
If there's a performance gain to be had, it's more likely to be in having the job queue take n job…

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…
To clarify on the anti-aliasing: Since we are always drawing from bitmaps which have alpha-blended…
There's really no such thing as non-32-bit-aligned 32-bit value on the stack unless you really go …
What other platforms are you talking about? You have working TLS also on Linux, OSX, Android and i…
The point of the queue here is not to maximize the amount of sleeping, but rather minimize the amo…
We haven't really gotten to the point where we need to start caring about thread_context. It's re…
I was wondering what the purpose of thread_context is now that multi-threading has added to HH. Do…
Such approach is fine. It will work. Just don't forget to increase max count. Semaphore value has …
If I was to implement something like this I'd probably go the route of the WaitForSingleObjectEx e…
Oh, you're right. Value will be 0 if no other jobs are being added. I don't know what I was thinki…
Ok, well I grabbed the source code and looking through it properly I can see there's no bug. I don…
Why do you think semaphore is at 0 at 4th step? Semaphore decreases only when WaitForSingleObjectE…
Apologies if I'm mistaken, but I just watched episode 126 and spotted what might be a possible rar…
then there is which will take care of alignment to arbitrary boundaries for you: that is, it wil…
_mm_mul_epu32 only multiplies 2 32-bit integers and stores result as 2 64-bit integers. So you wou…

Yes, for variables allocated on stack compiler aligns them automatically. It gets tricky with stuf…

Yes, I got VLIW somehow confused with SIMD, not sure why. SIMD executes one instruction on several…
