NVIDIA’s David Kirk Interview on CUDA, CPUs and GPUs

David Kirk, Nvidia’s Chief Scientist, interviewed by the guys at bit-tech.net.

Read the full interview HERE.

Here are some snippets of this 8-page interview:

page1
“Kirk’s role within Nvidia sounds many times simpler than it actually is: he oversees technology progression and he is responsible for creating the next generation of graphics. He’s not just working on tomorrow’s technology, but he’s also working on what’s coming out the day after that, too.”
“I think that if you look at any kind of computational problem that has a lot of parallelism and a lot of data, the GPU is an architecture that is better suited than that. It’s possible that you could make the CPUs more GPU-like, but then you run the risk of them being less good at what they’re good at now”
“The reason for that is because GPUs and CPUs are very different. If you built a hybrid of the two, it would do both kinds of tasks poorly instead of doing both well,”

page 2:
“Nvidia has talked about hardware support for double precision in the past—especially when Tesla launched—but there are no shipping GPUs supporting it in hardware yet”
“our next products will support double precision.”
“David talked about expanding CUDA other hardware vendors, and the fact that this is going to require them to implement support for C.”
“current ATI hardware cannot run C code, so the question is: has Nvidia talked with competitors (like ATI) about running C on their hardware?”

page 3:
“It amazes me that people adopted Cell [the pseudo eight-core processor used in the PS3] because they needed to run things several times faster. GPUs are hundreds of times faster so really if the argument was right then, it’s really right now.”

Quick Review – HWMonitor 1.0.5.8

HWMonitor pour, vous l’aurez sans doute deviné, HardWare Monitor est un tout petit utilitaire (732k) dont le but, réchauffement climatique oblige, est d’afficher les différentes températures du PC: CPU, GPU, disques durs, chipset ainsi que les tenions d’alimentation.

Sur ma machine de test voilà ce que ça donne:



Température du CPU


Température du GPU


Température du disque dur


Température du chipset

HWMonitor ne nessécite pas d’installation, est simple d’utilisation et fonctionne bien. A avoir dans sa toolbox!

La homepage de ce petit tool se trouve ici: www.cpuid.com/hwmonitor.php.


Quick Review – Asus Silient Square Pro

Voilà le nouveau ventirad pour le cpu que j’ai installé sur ma machine de test:

Je dois dire que j’en suis assez satisfait. Facile à installer, ce ventirad d’Asus est quasiment inaudible. Et il rempli à merveille sa fonction de dissipation car les aillettes restent froides en permanence. Evidemment, je pense que c’est mon AMD X2 3800+ qui ne chauffe pas assez mais par rapport au ventirad d’origine livré avec le cpu, la différence est nette.

Du bon matos :thumbup:
