Robot on 2 or more processor workstation

[anton.belyakov]

Hello! My company is working on increasing the speed of calculations in Robot. So the question is will the program work on 2 processor (not 2 core)  workstation and will it increase the performance of the programm? Thanks.

There is no difference if you use multi core processor or multi processor machine

Here is the document which operations are \ can be run on separate core \ processor

In some cases Robot can use multiple processors. For instance the
following operations in Robot are run as separate threads :
1/ FEM analysis
2/ calculations of theoretical reinforcement in plates
3/ calculations of theoretical reinforcement in bars
4/ each calculations of steel/aluminium/timber design

Each of these threads can use up to 100% of resources of one processor.

So for instance for FEM analysis the advantages of several
processors are not very significant (solver can use only one processor
except multithreaded solver)
but if you perform some other operations (like viewing, sorting tables,
analysing graphical views, selecting some objects, etc.) during analysis
Robot will be faster because solver will use one processor and second
processor will be used for these operations.
Similar situation concerns speed of Robot when performing operations 2/
3/ 4/.

Higher advantages can be obtained when performing simultaneously
operations 2/ 3/ 4/ - each of them can be performed by different
processor.

Moreover as concerns operation 4/ (steel/aluminium/timber design) user
can start several such calculations simultaneously with for instance
different list of members or groups and each of them can be performed by
different processor.

Thank you for such a detailed answer.

Hello,

i have just read your answers for this issues, but i have one questions for "Product Support", how long we can use GPU to caculate for "Robot, Revit" or processing some thing interdepand caculation for " Autodesk Product" ???

i have wait too long since the GPU workstation release by Nvidia.

we will very happiness for this ....

now,sleep... dreaming...working and waiting.

I am afraid I do not understant.

CPU is used as long as required by program, sometimes a few seconds, sometimes minutes, hours, days. It depends on model size and type and number of cases to ba calculated.

Dear,

in here, i taking about "caculation" is mean " Big and complex caculations".

for example: when i creating or copying some or more objects in "Autocad Structures Detailing", it will be re-caculate for all, but so strange, in the "Duo Core CPU and HDD normal" vs "Xeon CPU and SSD" not so diffrence. ( of couse two computers have a lot of difference at all )

And the issues in here, is not a Hardware fail.

comeback to the Autodesk Robot, it's still not so diffrence.

So, Why we don't make a change, Autodesk and Nvidia, sit together, and talking about this issues, and more issues to make something bigger, something faster, we have paid a lot of money per years to buy an Autodesk Product for what? Beause i believed Autodest can do anything we need.

Yes, i'm talking about GPU Computing Technology for Autodest Robot, and more Autodesk products.

Send me model I can tell you how it works on our computers

[lythetich]

okie,

The first one:

Mainboard: Socket 775 

CPU: core 2 dou E7800

RAM: 4GB bus 667

HDD 5400rpm

VGA: Intel 

Windows XP 32bit SP 3

AutoCAD Structures Detailing 2012

The second:

Mainboard: socket 1155

CPU: Xeon E1230v3

RAM: 8GB bus 1600

HDD: SSD Kingston 120GB

VGA: Quadro 2000 

Windows 7 Pro 64bit

AutoCAD Structural Detaing 2014

that is summary, please tell me something you want make to know about it.

???????????????

[lythetich]

sorry, i'm so stupid for "model" mean, so sorry,
but the model processing in my company is private, i can't send to you, or share it in the public,
but, there model is 50 floor building, so you can thinking, it's will be great. hi

What he meant is that will Robot be GPU accelerated in the future much like Maya which uses CUDA or OpenCL?

Hi!! In RSA 2014, when I run "3d generate " in wind load, it appears " out of memory". I don't know why, while my PC has 4G of ram and process in window 7 ultimate, 32 bit....

[Rafal.Gaweda]

4GB RAM, 32 bit system - not much
I think You need new comp with 64 bit system and 8 or 12+ GB RAM

[e2009355]

Thank very much!! But if I use rsa 2012, it's ok?

[Rafal.Gaweda]

The issue is with the lack of memory, not the Robot version.
Use 2012 2013 2014 2015 on 64 bits

[e2009355]

And is there the way to add memory into rsa?

[Rafal.Gaweda]

And is there the way to add memory into rsa?

To RSA?

Not possible for your computer to have more than 4 GB because you have 32 bit system.

Send me the file, write what to set and I will check it.

Hello

I am using Robot each day on doing very complex and complicated models - up to and over 200 000 FEM nodes. Wwe are using machines with many processors. Robot uses only one of them - for designing gometry and loads. The same thing with calculations.

The problem is not with the designing - but with the calculations - it takes hours to calculate our projects. The thing is that Robot does not use the whole potention off our work stations.

It is possible to lounch many Robot applications at one time - the calculation and designing time will be the same - too long.

Please do something about it.

[jkwiatko]

And this is a serious probleme - that Autodesk tries to replace with cloud - the issues are:
1. Cloud is another cost - why pay for this if You are not using your own machine ?
2. How about internet connection - and uploading - downloading files form server and up to server... Preety exhausting..

[lythetich]

Yep! I agree with jkwiatko.

1. The internet connection is the first issue.
2. Data in project is confidential.
3. Can't use fullload the of the system.

and a few inconvenient when we can't use fullload of our system, it will wonderfull when robot can use multi processor, or use GPU for calculation.
