    Build Complete New Threadripper Pro

    Hi AT crew, it's been a while since I've been on. I thought some people might be interested to see a Threadripper Pro build! I'm curious if anyone can recommend some multithreaded benchmarks to try out. I ran CPUz's multithreaded and came up with 210,000... I ran Prime95 with 64 threads and...

    Got a GV100

    So, I built another one of these... http://www.portvapes.co.uk/?id=Latest-exam-1Z0-876-Dumps&exid=threads/ideas-for-high-end-simulation-workstation.2533367/ And this one gets a GV100. :-)

    Ideas for high end simulation workstation

    Ok, we got it built! It's a beast. Ended up with this parts list: Xeon Gold 6146 (12c 3.2GHz) x 2 SuperMicro X11DPI-N 12 x 16GB 2666 = 192GB (was going to use 8GB but were out of stock... bummer) Samsung 960 EVO 1TB SSD WD4000FYYZ 4TB 7200 Cooler Master HAF X Ultra 1000W Titanium (ED: ran out...

    Ideas for high end simulation workstation

    Thanks for the pointer tamz, it looks like those processors actually can turbo higher than what I've been using (the "turbo" number for the Ark site). Here's a great overview (see page 13)...

    Ideas for high end simulation workstation

    Huh, I didn't even think about Threadripper. It is in the right performance range and I like the 4ghz boost clock. The only downside is the 4 channels of memory. I have been in contact with the vendor though we mostly discussed the GPU side of things. They highly recommended a dual processor...

    Ideas for high end simulation workstation

    Atari, I have a good baseline as we use this tool probably half of the day. For single thread operations I'd like to have an improvement so at least 3.5GHz peak turbo speed. For multithreaded simulation it doesn't use the available SMT threads. Overnight - we do some longer simulations...

    Ideas for high end simulation workstation

    Hi everyone, I put together a beefy machine 3 years ago for EM simulation using CST. It has the following needs: 1. Single-core processing speed (for 3d modeling - math-based, lots of trig) 2. Multi-core processing speed (for certain phases of the simulation process) 3. GPU processing speed...

    Help finding EPYC motherboard

    Memory bandwidth is the limiting factor. I'm doing EM simulations with CST. I built a nice box 3 years ago but may need a new one soon. It saves me 15-25% to build it myself. And I've been building boxes since 2001 and just enjoy it. :)...

    Help finding EPYC motherboard

    Thanks for the comments guys! I did see that Supermicro board which is pretty similar to the Gigabyte. Yes, it seems just a bit early for an Epyc system. I'm fine with a dual socket board too and just using one if they work that way. I don't need 10 gbe, just a single gigabit port...

    Help finding EPYC motherboard

    Thanks, but I'd rather put it in a standard tower than a server slot.

    Help finding EPYC motherboard

    Hi all, I'm looking for a workstation level motherboard for an EPYC processor and am finding rather skimpy results. I only need a single processor. The only one I found had 10gbit Ethernet with a funny connector for fiber that I can't use...

    New high power compute workstation - comments?

    My buddy ran a CST simulation he had set up and it took 20 minutes compared to all day on his old desktop. :-)

    New high power compute workstation - comments?

    The EM software is CST: https://www.cst.com/

    New high power compute workstation - comments?

    Well it's all done! I did some stress testing too. Pretty fun to run 35 Prime95 workers, RTHDRIBL, and fahbench all at once. Got 47.3ns/day in fahbench, while everything else was running so it looks like it's going full speed. https://foldingforum.org/viewtopic.php?f=38&t=24225 It's right...

    Best place to buy used oscilloscope?

    I've bought a lot of test equipment from Ebay including spectrum and network analyzers.
