I ran the benchmark several times and submitted the result before I went to the USA but it didn't get posted to the site. I haven't had a chance to figure out why yet...

Hi Rick,

EE Times reported last month that :-

A spokesman for Micron confirmed the filing and said "Micron aggressively protects its intellectual property worldwide and will use all available legal options to remedy any misappropriation."

While this particular case smacks to McClean of industrial espionage, he believes the real high-stakes lawsuits will come when JHICC and other Chinese companies start marketing chips. Once they begin producing chips, Samsung, Hynix and Micron will have a chance to examine them to look for evidence that their patents are being infringed, he said.

"When they start producing, then they will have product to look at," McClean said. "That's when the real fun will begin. The lawyers are going to have a field day."

For example, Yangtzee is reportedly moving quickly to develop 3D NAND flash, the state-of-the-art technology which established vendors led by Samsung are ramping up now. McClean doesn't know how this could be done without running afoul of patents held by the established players. "I think it's just about impossible for anyone to produce 3D NAND without stepping on some of their patents," he said.

It reminds me of when I was in Beijing in 1984. It was just a sea of
bicycles and the only cars were some taxis and a few government vehicles.

Some locals looked frightened to see you if they turned around in the street
and you happened to be there behind them. You may as well have been
from another planet.

When you saw another westerner you tended to acknowledge each other
with a little nod.

At the hotel I was having dinner and a Chinese chap introduced himself as
being a member of the "Australia-China Friendship Society".

I asked him what he thought the major purpose of the Australia-China
Friendship Society was?

He replied, "to assist China in giving back the technology that is rightfully hers of which the west has been guardians of for these past centuries".

I looked at his face and he was serious.

Got a couple of Linux benchmarks uploaded now (swap on SSD and RAM disk):

From memory I get about 4,500-5000 as a total performance, would that mean that you’d be getting ~4x the speed increase?

Curious as to whether it works that way

If I'm reading those benchmarks correctly, there's no real advantage using a RAM disk? Assuming I have not made a mistake there, I guess this would be because of how much memory you've got and Linux's excellent page/buffer support. It's excellent news as you don't have "fear" a power outage and lose your swap cache.

It depends on whether your workload is similar to the benchmark, Colin My old system is an i7-960 that also does around 5,000. On my tests so far the new system is 4 to 10 times faster on time-consuming processes like calibration, registration, drizzle integration and linear normalization.

Yes, I think that's right, Chris. The improvement from the RAM disk is fairly small. The comparison is with a NVMe SSD. If I was using a SATA SSD or, heaven forbid, a spinning disk then the difference would likely be significant.

Well that’s good to know Rick.
My MacBook Pro has done me well for the past few years but I have been thinking of getting a desktop for processing mosaics. When working with 16MP or less images the time taken for most processes is pretty short anyway. Once Local Normalisation and Drizzle come in however, I push go and go to bed or go to work

I'm hoping a coffee break will be long enough with the new box

First pass PI benchmark on mine:

Code:
CPU Identification
CPU vendor ............. AuthenticAMD
CPU model .............. AMD Ryzen Threadripper 1950X 16-Core Processor

System Information
Platform ............... Linux
Operating system ....... 4.15.4-gentoo #9 SMP PREEMPT Sun Feb 25 14:40:15 AEST 2018 GNU/Linux
Core version ........... PixInsight Core 01.08.05.1352 (x64)
Logical processors ..... 32
Total memory size ...... 62.885 GiB

Execution Times
Total time ............. 00:20.19
CPU time ............... 00:18.30
Swap time .............. 00:01.87
Swap transfer rate ..... 8858.208 MiB/s

Performance Indices
Total performance ...... 23304
CPU performance ........ 20683
Swap performance ....... 49061
While it was running, the CPU freq seemed to be hitting up to mid 3600s (from the base 3400), so I suspect there's more head room there yet - I haven't worked out how to overclock the cpu properly yet - just using auto settings.

Also, my memory sticks are at default timings at 3466, not 3600.

Pretty happy with the results so far.

Nice one, Chris! I got your email. Will send you BIOS info when I'm able to reboot.

Cheers,
Rick.

Thanks Rick.

I submitted the benchmark to PI: http://pixinsight.com/benchmark/benc...DG5ZN9XCODM84A

It's now top of the list for TR builds, 2nd overall to some Intel 28 core system.

And to re-confirm what I've said before - Linux PI blows Windows out of the water. The best Windows version I can find is on remarkably similar hardware to mine: http://pixinsight.com/benchmark/benc...7T94Y1Q48I6377 and is only 2/3rd of what I'm getting. (Edit: it's CPU was overclocked to 4Ghz, I haven't done that)

Really recommend using Linux when using PI.

I also found Linux much faster than Windows... except for StarAlignment with distortion correction which runs more slowly on Linux, at least on the data sets I have tried. Weird, huh!

That is weird. I wonder if it's a bug?

I have it on my to-do list to try a few more data sets and then perhaps report it as an issue.

Tonight's effort:

Code:
CPU Identification
CPU vendor ............. AuthenticAMD
CPU model .............. AMD Ryzen Threadripper 1950X 16-Core Processor

System Information
Platform ............... Linux
Operating system ....... 4.15.4-gentoo #9 SMP PREEMPT Sun Feb 25 14:40:15 AEST 2018 GNU/Linux
Core version ........... PixInsight Core 01.08.05.1352 (x64)
Logical processors ..... 32
Total memory size ...... 62.885 GiB

Execution Times
Total time ............. 00:18.94
CPU time ............... 00:17.13
Swap time .............. 00:01.79
Swap transfer rate ..... 9251.000 MiB/s

Performance Indices
Total performance ...... 24838
CPU performance ........ 22092
Swap performance ....... 51237
32 unique directories for swap on the nvme disk. Really diminishing returns though.

Tightened the memory settings timings, but have yet to verify stability via memtest run.

No CPU overclocking yet (all "auto").

You got yourself a nice abacus Rick!

Now, if one connected two of those in parallel...
