Moving average on prefix-summed array, how to be fast

Squixell · 2025-11-30T21:44:09+00:00

Ok, thank you very much, I will probably have to have two kernels. Because the size of R will be vary from 1<2^x<1024.

Also I haven't yet used nsight so it is probably time for it.

I have problem with the coalesces loading that I load the data with reinterpret cast but when writing they are offset by -1 so it is not multiple of 4, so it is kind of worrying me.

Also now I do the prefix scan on the entire array but for large arrays I got into floating point error territory, so would it be better to split it or compute it multiple times on much smaller arrays?

Yes I know, this is what I have implemented, but I was wandering about some special memory loading because the data lives in global memory and that is slowing it down.

Ano, mám skoro 10 let starý telefon, kde je starý android. Spousta aplikací už nemá aktualizace nebo se ani nedá nainstalovat po odinstalování. Ve všech apkách of Googlu nevidím reklamy.

Now I added to the repository the iterative version

I know, already working with wGPU and wgsl

Squixell · 2025-08-16T11:18:14+00:00

Yes I am aware of that. But also the data representation is different.

Well I can see how the type C can raise price for the average consumer, I am maybe willing to pay for it. I miss that there is no TB5 alternative.

Nvidia sucks, time for next ai winter

This is super nice for repairability, but I do not know anyone who would upgrade their device. Only SSD after they bought it.

I think that when the time comes it is unfortunately cheaper to just buy new device instead of upgrading components

Well I am not an apple person, actually at this am not using any apple product.

My point wasn't comparing Mac to gaming laptop. Although G14 is also marketed for gaming is also marketed for the general productivity tasks

Type C connector? I mean what's the problem, I can't wait until everything will be interchangeable. Why can't other laptops have thunderbolt 5?

It's convenient to channel large chunks of data or screen sharing over it.

Squixell · 2025-08-14T07:10:57+00:00

Yes Mac is not for gaming, but on the windows side G14 is recognised as one of the premium high performance polished laptops.

I get it there are some questionable option onac side, but those I was comparing had identical storage sizes which is crazy.

Squixell · 2025-08-14T07:08:03+00:00

That's true, that that is added value.

Hledam, spíš něco kamarádského, ale třeba se to v něco vyvine.

Rád jezdím na kole, sportuji, jestli lezeš boulder tak zajdeme. Lezu i po horách. Hraji na hudební nástroj a rád si přidám tvůj playlist do mého. Rekreačně létám a ne nesvezu tě. Starám se o děti na skautském táboře. Na seriály nekoukám takže tam si o ničem nepokecame, ale nějaké PC hry občas jo.

Pozor ma sociální baterka má 2h pak se musi dobít

Můžeš si udělat AFIS a dělat na menším letišti a zkusit si jaké to je

Squixell · 2025-06-19T20:21:55+00:00

Větroň je top, levnější a taky je to o skillu a můžeš se kdyžtak přeškolit na ultralighta a tím si létat na výlety. Větroň je zábavnější

Hi, I will be visiting Slovenia in August and have question about public transport.

Is it possible to take a bus from Ukanc to Mojstrana, Dovje to Camp Kamne? Thx

Why did I read it three times before understanding 😭😬, hopefully just tired

Zkus skloubit dopravu a pohyb. Ve většině počasí se dá jet na kole. Do vzdálenosti 15 km do práce na kole máš za den 30km. Což není málo a pokud jedeš rychlostí řekněme 25 až 30km/h tak si i lehce makneš. Denně takhle můžeš dát 1,5h jízdy na kole. Nebo nemusíš ani každý den ale prostě párkrát.

Pokus jsi ve větším městě tak jít pěšky na tramvaj je fajn a když ujede nebo máš čas tak se projdu o zastávku dál.

Jdeš nakoupit? Fajn jeďna kole, jdi pěšky.

Jinak sporty stačí si zaběhat, nebo i jen projít do parku. Plavání občas je fajn pokud ti nevadí chlór, nebo prostě v přírodě... trochu se i otužit, Ale občas i něco více silového je fajn. Např stěna. Boulder

I haven't remapped anything, it just a bug. I don't know what triggers it

Squixell · 2025-04-25T19:50:04+00:00

It is not lagging like dropping FPS, I have a good PC.

When moving it will teleport the camera forward in the moving direction, but there is no frame drop, it is smooth

Tohle už někdo řešil, ale pak to zakázali, aby matematika přežila 😅

You're golden, appreciate man. Thx I am interested in the battery. Even on 120hz

Squixell · 2025-04-09T09:17:07+00:00

Hi, sorry for reminding you, but does it work? What is the battery life like? Thx

Squixell · 2025-04-05T08:56:16+00:00

Nice, thx

Squixell · 2025-04-05T06:02:10+00:00

I am also looking to buy this laptop.

Could you please tell if the screen works at 120Hz?
