LLightningZ71 replied to the thread Question CPUs for shared memory parallel computing.The memory usage information can be tricky. You need to compare the bandwidth limits of your system to the bandwidth saturation or...

LLightningZ71 replied to the thread Question CPUs for shared memory parallel computing.While running the tests, did you do any system profiling? Was it effectively keeping all cores busy? How busy was RAM? Did you notice...

LLightningZ71 replied to the thread Discussion Qualcomm Snapdragon Thread.Perhaps they are intending to use those die harvested chips in premium tablets. There is a market for tablets like the Surface or iPad...

LLightningZ71 replied to the thread Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000).The only notable improvement that AMD can do for gaming with the 9xxx x3d parts as compared to the 7xxx implementation is find a way to...

LLightningZ71 replied to the thread Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000).The ONLY real hope that the 9xxx series has from the X3d parts is that their performance is being held back a lot by the bandwidth...

LLightningZ71 replied to the thread Discussion Intel Meteor, Arrow, Lunar & Panther Lakes Discussion Threads.TSMC N7 and Intel 7 (10esf+) are broadly equivalent in many ways, but, when it came down to implementation, N7 had higher PRACTICAL...

LLightningZ71 replied to the thread Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000).MALL cache is there for a couple of reasons. Not only does it increase the effective bandwidth of main memory from the 256 bit 200+...

LLightningZ71 replied to the thread Discussion Future ARM Cortex + Neoverse µArchs Discussion.One other thing that I've seen profiled in the past when comparing the different ISAs is the number of "ops" per instruction. From what...

LLightningZ71 replied to the thread Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000).I think this sentence is key... In Apache HTTPD, PyTorch, and various other mostly multi-threaded apps like HPC/scientific computing...
-
LLightningZ71 replied to the thread Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000).Given how underwhelming the performance of Strix has been, they're going to have to practically neuter the clocks on the higher end Hawk...

LLightningZ71 replied to the thread Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000).Because "budget focused" didn't actually reduce the costs that much on the back end. There are a few of them out there, but they aren't...
-
LLightningZ71 replied to the thread Question CPUs for shared memory parallel computing.From your earlier post, it appears that your parallelism tends to hit a wall around 8 processes as scaling really falls off. I don't...

LLightningZ71 replied to the thread Discussion Intel Meteor, Arrow, Lunar & Panther Lakes Discussion Threads.Since Intel has a history of having consumer cores and xeon cores differing on AVX512, it's not far fetched to see the P cores being...
