Ideal specs for fastest processing?

  • 1.  Ideal specs for fastest processing?

    Posted 9 days ago

    Just looking to see if there is some type of overkill spec that will speed TBC up?  I know there are ways to change text and makes lines as solid etc , but id like a computer that can just handle it period without having to use trick settings.   We do fairly large solar sites and if you make one change to the surface there you sit for 4 minutes while it updates.  Does such a computer exist or is this just the limit of TBC?   

       Thanks!

    Hi Jason

    Go to the properties of you surface in TBC, then switch the Rebuild method to "By user". This will allow you to make multiple edits to you surface and TBC will not update the surface after each edit. When you press F4 to compute in TBC it will only then rebuild the surface with the edits you made.

    Regards

    Yeah, i know that trick and use it already.  Still doesn't solve the problem.  Id like to not have to do that.  Also, this doesn't do anything to help the report processing speed.  So is TBC just at its limits?

    I would make sure that you have at least 32 gigs of ram if not 64. Also, and most importantly, have a dedicated SSD nVME drive That's not your C drive for the data. A dedicated GPU with at least 8 GB of shared memory would be ideal as well. Lastly, make sure that you are downsampling/decimating your cloud with advanced filtering prior to creating a surface. I would never create a surface with 100% of the point cloud in the particular area of interest.

    Thanks Zach,  I will be looking into the info you provided.   I am already running 64GB ram and i also have a seperate SSD drive, but i am not using it the way you recommend.  I will try that. 

    Appreciate the advice.

    What computer specs do you currently use? CPU, ram, GPU ram

    And what all data do you have in a project?  scans, if so how much?  aerial photos?  or just individual observed points?

    That is assuming you're working with a point cloud of existing. TBC can be painfully slow building finish grade surfaces with way fewer objects than a point cloud. We've found it's mostly all software bottlenecks. Large solar jobs can be terrible.

    Thats what im afraid of.  Love TBC, but they have to do something about this.  We shouldn't have to run a special set of settings to avoid lag every time you zoom in and out. Terramodel never had this problem.  lol Not saying i want to go back to Terramodel, but man its frustrating. Civil 3D handles it just fine too.   Im willing to spend the money if there is a super computer setup that will solve the problem, but im already running more than the recommended specs. I have a feeling a super computer wont make any difference. 

    What computer specs are you running?

    Make sure you have a 12th generation or later intel processor. TBC rarely maxes out our hardware which just points to software bottle necks unfortunately.

    Multithreading has been discussed in the past Enhancement Request: Optimize TBC to use multiple CPU cores | Trimble Business Center

    According to Alan Sharp (back then still with Trimble) can surface creation/triangulation not be multithreaded. See post 4 here What PC specs? | Trimble Business Center

    I wouldn't be so sure about that, since you can find academic papers about multithreaded Delauney triangulation on the web. But that would require some pretty time-consuming rewrite of existing and working source code. And let's face it, we are just users who already paid the bill. The extra expense and subsequent decline in turnover would need to be justified to the shareholders. Sometimes I do consider changing to the dark side.

    Currently, for surface handling, the only advise is, get the best single thread CPU you can.
