I presume if you enable ECC and retest, you will get slower, and closer to Titan V
(wouldn't 3080Ti be faster than Titan V? If on cuda app its sitting more closely to mem bandwidth?)

and you can try/see if this one works on ampere/volta

this part of code doesn't state you need hopper *(should work on ampere) - and I think this is what you want

ECC enabled/disabled doesnt meaningfully change computation speed with Einstein that I've seen. but does seem to use more power if it is turned on. based on my testing with the A100-Drive system.

yes, a 3080Ti is faster than a Titan V for Einstein. but it uses like 2x the power, the Titan V is much more efficient, which is why I use it (and V100s) instead. the 3080Ti is a little faster than a V100 (~10%) for Einstein when all settings and app are the same.

I'm not sure how much of the computation is matrix multiplication, not sure that Tensors can be used that much. I would assume that the compiler and/or scheduler would recognize any matching computations and send them to the tensors wouldnt it? tensors on the Titan V and V100 dont have as much flexibility as on Ampere and up.

I'll take a look at the other resources you linked to

Looks like no benefits on Volta except on FP16 using Tensor Cores, only ampere and up actually do show good gains

*(but i would note that 4090/5090 do have locked tensor performance likely to stop them from cutting into their other tesla/quadro products)

Its not enabled by default, you would need to call upon it - and enable mixed precision.
TF32 isn't really FP32, as i understand it there are few different approaches of using tensor cores and most common GEMM is just allocating 2 fp16 into single fp32 flop accumulation model. Thus it might be impossible to get proper precision level that is acceptable by validator.

I'm not sure how it really works in code, nvidia supplied at least couple different things with tensors producing different numbers, sparsity, accumulations and so on; so each might have their own use/caveats.

A run on the "Intel" device (-p 0 -d 0) produced ~35GB/s. The 90GB/s+ above is a run on the "Apple" device. Not sure if this is referring to APIs or emulation, guessing APIs? Again it's an M2 Mac mini - definitely no Intel device onboard.

I can't say for sure since i'm unfamiliar with apple arch but likely the case of of using dedicated memory and shared system memory.
(mac's arm cpu might be detected as opencl device and thus dev 0 could be just your cpu)

can you take a look at gpu-z see if you have all rops etc? Could be same case for some being disabled.

*(You can try rerunning the bench with ecc disabled - should produce better speeds.)

Click to expand...
In GPU-Z it is as it should be according to specs:

gpuz-ad102.gif

And you are right, this ECC is definitively not how ECC should be done on a hardware-level, no additional memory chips, probably some kind of cheap Inline-ECC... ECC disabled gives about 120GB/s more VRAM throughput.
This GPU's are only about 8000$+, why should we care and invest in additional one or two gddr vram chips? We are anyway untouchable... i hope you get struck by a lightning Nvidia, like Intel!

I wonder what the cause of this is. Since it seems to happen at the very end on several different GPUs.

Is this an unspoken decision made by Nvidia to cheap out on the last memory module(s) like the whole GTX 970 “3.5GB” ram issue? (Which resulted in a class action lawsuit against Nvidia).

Or is this evidence that the final memory module in certain samples actually has some problem/defect that’s only evident in running this test.

Or is the benchmark tool incorrect for some models?

So it wasn't the case that 970 was shipped with 3.5G of fast and 0.5G of slower memory. But issue is likely the same, where the gpu is cut in such manner that removes L2 or memory controller that runs last die

I have a friend that wrote a fully cuda based memory benchmark - after i test i'll share it here prob later this week.
Code wise i've heard argument that it needs a power of 2 (2, 4, 8, 16, 32, 64 etc) but after inspecting the code it doesn't, and we saw 3090 having full speed 24G, then we have 16G or 8G cards that do not)

Hi, i asked the vendor about this problem and is was consistent wich another sample, and all the professional graphics cards are assembled by Nvidia themself themselves. But anyway, the answer to the problem was more than unsatisfactory:

A certain area of memory is reserved for various things and is "fed" with different data.
When the test then reaches this memory area, the existing data must first be swapped out elsewhere, which leads to the performance degradation.
There is apparently no solution to prevent this.
Click to expand...

Sounds like always, when big companies try to cover up the shit IMHO

A certain area of memory is reserved for various things and is "fed" with different data.
When the test then reaches this memory area, the existing data must first be swapped out elsewhere, which leads to the performance degradation.
There is apparently no solution to prevent this.

I would argue since A4000 and 3090 didn't have this issue but 3080Ti, A4500 did.
The ECC thing, well in past (P100) it costed you around 25% of compute performance.
