Nope but everyone is running in the "cloud" and there you are lucky to get 50K IOPS
This is one of the reasons I don't run in the cloud.

AMD Prepares 32-Core Naples CPUs for 1P and 2P Servers: Coming in Q2

Re: AMD Prepares 32-Core Naples CPUs for 1P and 2P Servers: Coming in Q2
#112I think Naples is a very exciting development, because: - 1S/2S is obviously where the pie is. Few servers are 4S. - 8 DDR4 channels per socket is twice the memory bandwidth of 2011, and still more than LGA-36712312whateverthenumberwas - First x86 server platform with SHA1/2 acceleration - 128 PCIe lanes in a 1S system is unprecedented All in all Naples seems like a very interesting platform for throughput-intensive…
My shallow understanding of big servers and IBM Z series amounted to "lots of dedicated IO processors". Seems like "mainstream" caught up with big blue.
Pretty much. Mainframes have been very I/O oriented from the start. Channel I/O (more or less DMA) with dedicated channel programs and processors can be very high-throughput.

"Lots of cores, lots of threads, and lots of main memory. That was the key." Very much this. Which is why I ended up theorycrafting that the AMD many core CPU's would be so useful.
Hmmm, isn't deep learning starting to pick up for genetics? No idea if it is actually is, but everyone in DL seems to be talking about it, I thought I'd ask someone actually in bioinformatics :)

#114Semi-ironically this looks like just the thing to use in a supercomputer controlling a good number of NVidia GPUs.
What would be really interesting if AMD CPUs and GPUs both support their Infinity Fabric concept. Heterogeneous systems with high-performance direct memory access is a huge deal.

The Ryzen 7 1800X has a TDP of 95W and beats the 140W Intel i7-6900K by 4% in performance. They've made some huge jumps in power efficiency. I don't know if AMD will make a new architecture or not, but I can't see why they wouldn't just release 32 Ryzen cores side-by-side and underclocked at the stock configuration.
The thermal design power is the maximum amount of heat generated by a computer chip or component that the cooling system in a computer is designed to dissipate in typical operation. TDP =/= power consumed
but TDP is also a function of power consumption, directly proportional. So comparing TDP of processors of similar fabrication should tell you about comparative power consumption if not the exact difference.

#116In previous threads there was discussion about Intel processors, specifically Skylake (which is a desktop processor), being superior for server workloads involving vectorization. How will Naples fare on this front?
That front remains to be seen. However, 128 lanes, 8 channel ram; It will make a mess out of Intel in the vm hosting arena. I'm glad I don't own any Intel stock atm :)
The VM hosting arena is exactly where cloud providers play.
A high core count, energy efficient CPU with IO out the wazoo?
I'm happy I bought AMD stock over the summer (:

yes but four modules of ryzen to make this beastly naples chip isn't going to be clocked at the same frequencies. the top end intel chips have TDPs of 165W but 4 ryzen chips at 3.6ghz have a tdp of 65w a piece and you're not going to see a 260W server chip if you want to sell into the datacenter.
Ryzen is highly-efficient up to 3.3GHz: https://forums.anandtech.com/threads/ryzen-strictly-technica...
Wow, that's pretty insane. Underclocked to 3.3Ghz it runs at ~42 watts and is benching at ~178.5% performance per watt vs stock clock. This CPU will be very interesting to see in the datacenter space.

It's quite rare to find GPUs being used in genetics.
Is that because the workloads are fundamentally unsuitable for current GPU architectures or because no one has took a good stab at it yet? I know very little about computation genetics/biology but it sounds interesting.
In the past several years, quite a few developers have tried GPUs for analyzing bio-sequences, but found the speedup is modest. Good GPUs are expensive. It is usually better to put that money on CPUs or RAM.

> TDP =/= power consumed
Where do you think the heat comes from? Or where do you think the power that doesn't turn into heat goes?

#120The important thing here, from my perspective, is how NUMA-ish a single socket configuration will be. According to the article, a single package is actually made up of 4 dies, each with its own memory (and presumably cache hierarchy, etc). While trivially parallelizable workloads (like HPC benchmarks) scale quite well regardless of system topology, not all workloads do so. And teaching kernel schedulers about 2 level…
Intel's largest CPUs are already explicitly NUMA on a single socket. They call it Cluster On Die: http://images.anandtech.com/doci/10401/03%20-%20Architectura...
Very true, I should have mentioned that. At least for us, COD doesn't seem to impact our performance at all, while NUMA does. I'm hoping that Naples is the same for us.
However, there is an important difference. AMD seems to be putting multiple dies into the same package, whereas Intel seems to have (as the Cluster on Die name implies) everything on the same die. So my fear is that the interconnect between dies may not be fast enough to paper-over our NUMA weaknesses.
