Grasshopper

algorithmic modeling for Rhino

Following a few recent discussions:

building-a-computer-around-kangaroo-physics-grasshopper

high-performance-computer-for-gh

hardware-requirements-and-suggestions

and inspired by the example of Holomark for Rhino, this is a first go at a very simple tool to get an idea of how fast different computers are at performing the sort of calculations used in Kangaroo, with the aim of informing those buying or upgrading their machines.

If you could take a couple of minutes to download and run this definition (after closing other running applications), then post here the result and your PC specs, hopefully we can start building a basic picture of what effect different hardware really has on the speed Kangaroo runs.

Image result for i7

Most of the information can be found in the System page of Control Panel.

RAM speed can be checked in your BIOS, or with a tool like CPU-Z (note that the reported frequency from this should be doubled to get the actual RAM speed rating - eg if the frequency is 800MHz you should write DDR3-1600. It's confusing I know - see some discussion of this here), or by searching online for the specs of your PC model number.

This definition is purely testing the speed of the internal physics calculation, not display, so graphics-cards are irrelevant.

For now this is just to get a single general measure of overall Kangaroo speed, but it might also be interesting later to run a variety of tests to see how the speed varies with the size and complexity of simulation.

Of course a way of benchmarking general Grasshopper performance would be very nice to have as well, but would involve a lot more variables, and I'd be interested if anyone has ideas about how that could work.

Note - I posted a couple of versions of this earlier with various errors that were causing incorrect results. If you downloaded the earlier KangaMark01.gh or KangaMark02.gh file, please disregard that and any results from it and use the one posted here below:

  Amount and speed of RAM:  16.0 GB @ 1600 Mhz (DDR3)

Do we want a high or a low score b.t.w.?

Higher score means faster

KangaMark Score: 88
PC model: Dell Alienware Area51 Desktop
Operating system: Windows 8.1
Processor model and speed: Intel Core i7 960 @ 3.20GHz
Amount and speed of RAM: 12GB DD3 1333Mhz

              KangaMark Score:  125
                         PC model:  Lenovo ThinkStation S30
              Operating system:  Windows 8.1 Pro
 Processor model and speed:  Intel Xeon E5 1620 v2 @ 3.70 GHz
   Amount and speed of RAM:  8 gB DDR3-1800

KangaMark Score:  127
PC model:  Lenovo Thinkstation Custom (desktop)
Operating system:  Windows 7 Home Pro
Processor model and speed:  Intel Xeon CPU E5-1620 v3@3.50GHz
Amount and speed of RAM:  64 GB DDR3 -1333Mhz

It's better to close all the other applications when running the test.

:)

Thanks Marios - yes, I'll update the post to mention that.

Is there any spatially reasonable laptop with Xeon processors ? ;)

BTW : TDP of my i7 4500u -15W, E5-1620 -120W. At least I'm environment friendly lol.

KangaMark Score: 64
PC model: Asus V5-573G
Operating system: Windows 7 Home Premium
Processor model and speed: i7-4500 U @ 1.8 GHz (up to 3.0 GHz)
Amount and speed of RAM: DDR3 12 GB 1600 Mhz

If using laptop, connect it to the charger (got 40 on battery). Not sure if it applies to all CPUs, but with "U" the speed is really altering.

@Mateusz is this the replacement for the other faulty gpu one?

It was actually display issue... fixed it with my bare hands, by bending it properly. Yes, bending.

KangaMark Score: 122
PC model: Custom PC
Operating system: Windows 7
Processor model and speed: i7 3820 @ 3.6gh
Amount and speed of RAM: 32GB DDR3 1600

i suspect some cpu strain degradation, after working 8 months in 4.1 overclock. did not expect that distance with I5 4670.
