Not sure which generation is but It looks at least the previous one. Newer ryzen models 3950x 3900x etc and new threadripper have a sensible higher
clock. (very close to the 9900k) I don't know if that make any difference with your app.
However, from the article I posted, the issue discovered that affect new gen. ryzen with Matlab is a concern. In the article They show how to avoid
the issue with a batch file, but anyway this could be the case with any other app that is optimized with intel processors. I wonder if that is the
case as well with your app. Currently this is the major issue I have with AMD as I am expecting to get the max computing power from the app I am
using.

Has anyone done before after testing on amd CPU using the mkl enabler? I have some amd servers here I will test but gsb does not use the mkl library
since it's written in c# I believe..I've done testing with opteron epyc and the performance is horrible

I've tested opteron and epyc I saw no performance gain if anything it was slower. Like I said gsb doesn't use the mkl library like matlab

About GSB and servers... I am thinking of adding some CPU resources to my GSB research... as i understand best bang for the bucks is dual xenon e
2680 v2 .. have people here experience running rack servers from their home? very noisy? other issues that make one want to use external server
halls instead? issue is though that cost for co location is around 60-70... and one can rent a dedicated dual 2680 v2 for around 120... so perhaps
no point of owning it... lots of thoughts...
Thanks for input

a 1u is extremly noisy.
Tower much quieter and about 30 watts less power due to less need for fans. i have a 1u that I took the top off, mounted some 90 mm fans over the cpu
with a plywood replacement top for the metal top that was on the 1u. the 6?? super micro fans are about 40mm, 10 watts each and sound like an airplane
engine.

When you put it like that Peter, a rack setup does not sounds that tempting

dual cpu https://www.cpubenchmark.net/cpu.php?cpu=AMD+EPYC+7601&id=31...
benchmarked at 3.43 minutes per gsb running (20 gsb running, 256 gb ram)
(low score is best)
I9 9980xe 128 gb , 10 gsb running runs at 1.87
i9 can have max of 128 gb.
xeons can have much more ram
I have no more recent amd
dual 2690v3 (not v2) with 256 gb of ram below
Im keen to benchmark another newer amd, but feel they are still very slow.
If anyone can source one to test, let me know
I also should have a dual xeon 2699v3 in a weeks time too.
(I have bought 3 more servers in the last few weeks)

Ryzen 9 3950X with only 16 cores now scores 39359.
https://www.cpubenchmark.net/cpu.php?cpu=AMD+Ryzen+9+3950X&i...
Per core that's 4.7 times faster than Dual EPYC 7601 at least in PassMark benchmark. Max RAM of 3950X is 128 GB.

Peter,
Ryzen 9 3950X is indeed a very good CPU but You may want also wait the new generation 4000 that will arrive before end of year with another great
improvement especially in the latency of controller and higher freq. per core.
If You want to try an amd machine You may want to check hetzner.com. They have dedi AMD cpu over there.

hetzners fastest machine is the amd 3900
What I suspect with AMD is we will need lots more copies of GSB running to max the cpu out. I will advise as soon as I get my hands on one to test.
thanks for the tips on the new amd. I was keen to go amd as was a bit annoyed with Intel. Basic things like really poor thermal contact between the
cpu and its lid. Make i9 hard to cool, esp of over clocked

I think the dual 7601 is 33545 total compared to 39359
so I dont expect a big increase.
Im happy to be proved wrong if I can get to test a machine.

I recently bought a used Dell Precision T7610 Workstation from Stalliontek.com with 2 x Xeon ES-2680's (8 cores each) and 128GB of Ram for about
US$1300. Found this vendor on Google. They literally have 1000's of used options and will configure to your specs. Arrived in 3 days. (I'm sure you
could save $ buying on Ebay, but the convenience factor was great.)
It was running very hot while using GSB.
Found this fix on YouTube: https://www.youtube.com/watch?v=Z68__gW-DGY
Now running loud but much cooler, allowing me to run more workers.

Great to hear. Better heatinks & fans can reduce temps a lot. Especially on 1u machines if you take the lid off the 1u with better cooling, but make
sure there is air flow on the smaller heatsinks in the machine

**SPECIAL COUPON: "COLO50" Get 50% off for LIFE off any 1U or 2U Colo Plan** (Brings the price down to $60)
This is no longer valid. Do you have another option?

One of the best companies ever to deal with, i have to say is the host steadfast, not the cheapest but for sure super reliable... been there for
years now using them for my own trading server setup, located at their Chicago center, very low ping to IB, ... their support answers within minutes
on email, and handles any issues you have on your server. Perhaps not needed if you are an experienced server admin, but for someone just wanting to
have a host that just works, sorts you out, and is super reliable they are awesome.. for a price tag though....

New to this server concept. I am in the process of buying/installing a server to expand my limited cpu/ram capacity. Do I need additional GSB
license to run it on the additional hardware or I can dedicate jobs from my computer to the additional server/computer?
Thanks

you need addition license $400 or revoke your first machine

So, if I have 4 rack servers, it would require 4 licenses? Thanks

I'm in the market for a new PC (only for GSB and TradeStation).
The new AMD chips seem to be very fast and some models have a lot of cores.
Can each worker on GSB use multiple cores? Or would, for instance in case my system had 128GB of RAM, 16 or 40 cores be overkill for that amount for
RAM?
Is anyone using or has anyone tried out the newer AMD processors in combination with GSB?
Any other thoughts?

GSB uses all cores. AMD is extremely slow for GSB and I strongly recommend not to buy one.
basically go to these charts and choose what you consider best bang for buck
https://www.cpubenchmark.net/high_end_cpus.html
https://www.cpubenchmark.net/multi_cpu.html
I'm replacing my intel dual 2680/90 v2 with dual 2699v3
there are similar cpu's, a little cheaper like 2697v3
I buy used supermciro servers.
the alternative is a I( cpu with 3 fan water cooler
I did benchmark a high end amd and about a year ago.
it ran the same speed as dual 2699v3, but cost about twice the price
