Low CPU/GPU performance

Trebh · 2019-03-30 19:24:53

Hi Everyone,

I have just built my new system, installed Arch and doing some initial benchmarks I'm getting very weird results.
Both CPU and GPU show really bad performance in multiple workloads tested with Phoronix Test Suite.

Some data about the system

OS: Arch Linux
Kernel: x86_64 Linux 5.0.4
CPU: Threadripper 2950x currently clocked at 4Ghz
Motherboard: Asus Zenith Extreme Alpha
Bios version: 0207
RAM: 64 GB at 3000Mhz
GPUs: 2 x RTX 2080 ti Gigabyte turbo

nvidia driver version: 418.56

from nvidia-smi:
power usage cap is 250W
Performance level is correctly ramped up by PowerMizer (nvidia-settings). Setting it to max performance manually doesn't change results.

CPU and Gpus are watercooled with a custom loop by EK: 360 + 240 radiators, loop order pupm/res combo, CPU, 360 rad, GPUs (parallel), 240 rad, pump/res combo
Temperatures are ~40 C idle, ~60C highest load. They are higher than I expected, and I might reseat both GPUs / replace thermal paddings, but I don't think that I am reaching thermal throttling.

Everything during BIOS setup and software installation went smoothly, all hardware is recognized properly and Arch seem to be working just fine as always.

BUT.
Performing some unigine benchmarks I am getting ~ 20 fps in every test (valley, heaven, superposition), doesn't matter if I change settings from basic to ultra or whether I toggle occlusion shadows or refraction.
Power draw ranges from ~ 80W to 200W when doing Unigine superposition at Ultra settings.
Gpu utilization ranges from 15% to 60%.

At first I thought about some NVIDIA driver issues, then I started some tests on the CPU and core performance is very bad too.
Example: Scimark2 Computational test: composite yields a result of 488 Mflops, lower than an AMD Athlon II. Just for comparison, a Core i3 2100 on Openbenchmarking.org scores 1065 Mflops.
I get silmilar results from other tests aswell.
I also tried multithreaded benchmarks like himeno and again I get 1087 Mflops. i7 6700K scores 2626 Mflops.

Anomalies during CPU tests I noticed with top:
single core usage doesn't go past ~50% (shouldn't it stress to 100%?)
multithreaded tests are actually using just one core (and it goes to 100% usage in these tests)

from sensors data:
CPU temperature is ~13C idle, reached 25C during tests at worst, then went down quickly.

To complete the overview, ramspeed test with Phoronix Test Suite yields expected results. RAM seem to be working nicely.

Any idea about what's going on? Am I missing something obvious? GPU bad performance could be the result of a bottleneck due to CPU single core severely underperforming - afterall I am pairing lower-than-i3 performance with a double 2080 ti - but then why is my TR behaving that badly? If this was due to some mistake I made during CPU seating I would expect to see way higher temps...

Hard to tell, but let's try another benchmark, hardinfo .

I've run all benchmarks on my Threadripper 1920x with 16 GB ECC 2400Mhz ram and uploaded the report to
https://app.box.com/s/ezu5lyqey6dzyx04mhh9tzhq74xr9302
Your system should perform much better.

single core usage doesn't go past ~50%

You do have SMT enabled?

Try passing "nospectre_v1 nospectre_v2" to the kernel (yes, that's the S.P.E.C.T.R.E patches…) and see whether that has *major* impact on the performance.
If yes, you can try to narrow things down: https://raw.githubusercontent.com/torva … meters.txt
SPECTREv2 is said to be the performance killer and not better than just deactivating SMT.

@seth nospectre_v1 only makes a difference on powerpc. The x86 mitigation is always on. The SMT related ones are opt in for tasks via prctl unless they use seccomp which is taken as auto opt in.

Spectre V2 : User space: Mitigation: STIBP via seccomp and prctl
Speculative Store Bypass: Mitigation: Speculative Store Bypass disabled via prctl and seccomp

I just tried hardinfo benchmarks and my system performs better, though I am not sure about comparisons...

I uploaded results here https://ufile.io/nzwsn

Is the system affected by https://bbs.archlinux.org/viewtopic.php?id=244919 ?

I don't have any reason to believe SMT isn't enabled: how can I check this?
I tried to add those parameters in GRUB but I didn't notice any difference. If I try to add them with sysctl, such as

sudo sysctl nospectre_v1

I get:

cannot stat /proc/sys/nospectre_v1: No such file or directory

because, well, there's no such file of course

"cat /proc/cpuinfo", "lscpu"

As loqs pointed out, the stubborn facts on the status quo contradict my big beautiful theory on spectre mitigations being the cause (unless you actively activated them before…)

If I understand correctly the problem in that situation is beacuse of SLI AA not working properly.

My 2080 TIs are not in SLI though, so I don't think that should be the case. Anyway this is the output for journalctl -kb -1

https://bbs.archlinux.org/viewtopic.php?id=244919 appears to deal with a system running an intel processor, probably a different issue.

Page 1-8 in the (english) user manual for your mobo has a table showing pcie slot possibilities.
It shows 3 columns : single vga , SLI/CFX , 3 way SLI/CFX

What slots do your videocards use and are you certain your mobo can handle 2 independent videocards ?

I am using slot 1 and 3 to use full x16 bandwidth as specified by the manual.
I honestly never thought the mobo might not be able to handle the cards independently: I have a NVLink and I will try to see if enabling SLI changes anything, but I am quite skeptical about that.

Also that would not explain CPU performance right? So I guess I would still be unable to test the GPU with this CPU bottleneck.

Trebh · 2019-04-03 20:43:04

UPDATE:

I was not able to setup SLI properly, tried everything in the wiki - SLI on one monitor only, twinview, mosaic - but I think I'll need more time for that.

BUT

I reset CMOS again (I was running a lightly overclocked profile I found on the ASUS bios) and:
- CPU is still performing badly
- GPUs now yield ~ 60 fps on unigine benchmarks. In superposition 1080 extreme preset I scored 7150, which is not exactly good - that's 2080 / 1080 ti performance range - but it's still way better than before. I honestly don't understand what's going on.

Edit: I just noticed that Unigine Superposition states that my Threadripper is clocked at ~500Mhz (actual).

Perhaps something is wrong with your cooling? Like, maybe the water block does not have good contact with the CPU? Or maybe the radiators weren't flushed enough times before you assembled everything and then dirt got loose and is now stuck in the block?

You write you see "~60°C" under load, and looking around online I find that Threadripper apparently already throttles at 68°C. Maybe that's your problem? The CPU is deciding to run at very low MHz because of temperatures?

60C Is the maximum i ever reached with the GPUs (sorry, wrote that part poorly).
CPU never reaches 50C under stress.

That said I will still probably dry the system / reseat CPU, GPUs etc. during the weekend.
I flushed radiators following EK instructions (distilled water + vinegar then just distilled water several times)

Trebh · 2019-04-03 22:19:01

I can reliably reproduce this situation:

Stock CPU/RAM clock (3.5GHZ/2166MHZ)
unigine benchmarks run @ 60 fps regardless of configuration, CPU seems to bottleneck running almost @ 100% single core

OC (4.0ghz CPU, 3GHZ RAM)
Same benchmarks drop to 20fps, CPU single core runs at 40 or 50%

seth · 2019-04-04 06:29:09

Does lscpu suggest you're still in the powersavong (or whatever low frequency) mode when running the benchmark?
Can you cpupower the frequency up (eg. by selecting the performance mode)?https://wiki.archlinux.org/index.php/CPU_frequency_scaling#cpupower

60fps sounds suspiciously like a vsync limitation and the driver might conduct a busy wait (charging at least one thread of one core)

$ export __GL_YIELD="USLEEP" # remains vsync but might lower the cpu load
$ fancy_graphics_demo
$ export __GL_SYNC_TO_VBLANK=0 # no sync
$ fancy_graphics_demo

I guess the overclocking "breaks" the CPUs frequency scaling?

TL;DR : scimark2 results are useful for singlethreaded performance, not multithreaded

I've run the PTS Scimark2 tests with stock values, see https://openbenchmarking.org/result/190 … R1920XSC64

I very much doubt they're useful for comparison though :

https://math.nist.gov/scimark2/faq.html wrote:

Are the SciMark kernels multithreaded?
No. SciMark 2.0 focuses on single-processor performance. Multithreaded kernels may be included in future versions.

I've also ran the multicore suite see https://openbenchmarking.org/result/190 … R1920XMU50
The terminal output was interesting, here's an example :

TL;DR : scimark2 results are useful for singlethreaded performance, not multithreaded

I know that, still my CPU is performing worse in those single core tests than an i3. In some cases it's on par with AMD Athlon II.

For multithread I tried himeno from the PTS but it seems it's not actually running on multiple cores. That said the main issue is single core performance I believe...
I'll post some results when I get home

Does lscpu suggest you're still in the powersavong (or whatever low frequency) mode when running the benchmark?
Can you cpupower the frequency up (eg. by selecting the performance mode)?https://wiki.archlinux.org/index.php/CPU_frequency_scaling#cpupower
60fps sounds suspiciously like a vsync limitation and the driver might conduct a busy wait (charging at least one thread of one core)
$ export __GL_YIELD="USLEEP" # remains vsync but might lower the cpu load
$ fancy_graphics_demo
$ export __GL_SYNC_TO_VBLANK=0 # no sync
$ fancy_graphics_demo
I guess the overclocking "breaks" the CPUs frequency scaling?

I think Vsync was not turned on but I will definitely check.
CPU in power saving mode is something I will also look into, thanks!

I've run the PTS Scimark2 tests with stock values, see https://openbenchmarking.org/result/190 … R1920XSC64

I very much doubt they're useful for comparison though :

Are the SciMark kernels multithreaded?
No. SciMark 2.0 focuses on single-processor performance. Multithreaded kernels may be included in future versions.

I've also ran the multicore suite see https://openbenchmarking.org/result/190 … R1920XMU50
The terminal output was interesting, here's an example :

I run the ptys/povray test and I can clearly see that it is using all 32 threads. The result (I believe) is actually good, and this means that the CPU is working fine when multithreading

Regarding VSync: it was on, disabling it has no effect whatsoever though.

I installed cpupower and set to performance: temps went a bit higher, but I did not notice any difference in GPU or single core tests
