It's a ripper

Got a new processing workstation for myself as a Xmas present. It's not even breaking sweat registering 200+ subs... AMD Threadripper 1950X CPU (16 cores, 32 threads) with 64GB DDR4 RAM and a NVMe SSD drive.

Cheers,
Rick.

Run a PI benchmark and post the results.

I ran some last night. On Linux I was beating the latest Threadripper benchmarks (which all appear to be on Windows.) I was planning to do a little optimisation (RAM disk, etc.) before I go public with results

Nice one Rick, but where did you get 200+ subs from did you sneakily get a CMOS camera too and not tell us?

They're real (long) subs, Dunk

A long drizzle integration has gone from 47 mins on my old system down to 10...

Other optimisations to consider that will tweak it more:

* Build your own custom kernel, compile the OS and packages with optimised settings. In the past this could give up to 10% or more improvements on generic linux distro installs. These days I doubt it would be close to that, but it still should be a couple of percent.

* Overclock, CPU of course, but tweaking the memory timings/settings I've heard can give great results.

* RAID set up on disks.

...but that requires a bit of work, so it's probably easier to enjoy what you've got.

Will probably play with the memory settings to make sure I'm taking advantage of the 3600MHz RAM but probably won't go much further. I'd rather spend my time processing!

The old computer was capable of raising the room temp by a couple of degrees. Should be able to do "better" now. Fortunately, the A/C is overspecced

If you plug it in to 480V instead of 240V it will go even faster for a brief time.

Thanks, Troy. I'm going to run it off a Tesla coil.

Well with all that data coming in from your whole Earth optical array, you will need it!...

That's true, Mike. I'm aiming for a scope on every continent

Sounds like it makes short work of all that read noise then Rick

Incidentally, what form factor did you choose Rick?

I wouldn’t mind one, but having used an all-in-one for years, not sure I could go back to a big ugly box

I’ll be amazed if they come out with a mobo in micro ITX format...could easily hide that behind the kettle.

Yes Dunk, if you can integrate fast enough the noise gets left behind

Full tower. I have a large desk with lots of room underneath and I'll be adding a bunch more drives. Fortunately, the glass door is facing the far side of the desk so I don't get a continuous disco light show. Even the RAM has coloured LEDs

Yeah coloured LEDs could be a bit much unless they could be programmed to represent, say, CPU usage or something useful
