But it takes another 5 + seconds to load the first assembly or drawing etc.... :smileyvery-happy:

Main points for consideration: (from one of my previous posts)

 

overal clock speed not so important

clock speed of individual core...some importance

fast read write from your drives (try opening 50,000 part files from a 5400 single drive) important

lotsa fast ram (see if your page file can handle 200,000 instances of 80,000 parts) important

good chipset and mobo with good buslines and no bottlenecks....IMPORTANT(this is the one that most people get wrong)

good pc setup (temp folder and page file isolated to reduce fragmentation etc) important

good pc maintenance (defrag defrag defrag) important

graphics card...looks like pretty much any half decent gaming (directx) card will do

 

 

the ssd drives as per mcgyvers post are great for the os and programs, but not so good for data retreaval rates.

frastest data config will be scsi (but cost is bad value compared to amount of extra kick) stripped 10000rpm sata3 hdds (ones with a high platter density) are the best bang for buck atm, if you need redundancy a 4x hdd in raid10 is the go.

Richos, you forgot to mention some important points about defrag.

 

Disk defrag on SSD drives = bad bad bad!!

 

If Windows has not automatically removed your SSD from the defrag schedule, then do it now.

 

For conventional plater based system drives defrag occassionally (Once a month). Non system drives used for storage where deleting of files is a minimum, do not need frequent disk defrag, it only wastes resources/time.

 

On drives where files are frequently deleted then defrag should be used accordingly.

good point, thanks

 

i generaly setup defrag to run every aternoon...whilst i wash my coffee mug...if done daily and before/after new software installs, then it only takes a couple of minutes (the time it takes to wash my mug)...so for the little effort i think it is well worth doing....i have identical setups to other drafters, defraging is the only difference...they seem to have a LOT more lagging and crashing issues.

Obviously, that's a good regime for you Richos, but I often see defrag abuse ... :smileyvery-happy:

 

A lot of unknowing folks, think that defrag is the be all and endall of computer maintenence, not so, of course. Cleaning ones 'temp' folder often has more effect than defrag does.

 

But in some cases it does help to defrag, especially in an office type situation where the drives are usually being hammered, in the home it's a different story though and it depends on the user/s and the amount of usage in general.

 

Also, try waiting for 10TB + worth of drives to defrag .... not fun! ... :smileyvery-happy:

Re: Autodesk Inventor PC Recommendation

06-05-2012 08:01 PM in reply to: trumpy81

all valid points trumpy

 

i have a routine...clean sweep temp files, defrag, incramental backup (if done daily without fail it takes less than 5 mins...miss a day and wait 10 mins...miss a week wait half hour...miss a month wait up to 4 hours)

Working on large assemblies, Inventor opens and closes a ton of files, if you are using skeletal modeling, every time you update the skeleton, all files that reference it directly or indirectly are modified this makes for a rapid fragmenting of your files, when the assembly goes looking for 1000 files to load and each one is in 4 or 5 fragments on your hard drive, you will be hearing a lot of whering and whizing from the box (for what may seem an eternity), this is the hard drives trying to put back together all those fragments of files. this is where the performance of opening and saving large assemblies will drop off dramatically

if your not working with big models, then your scenario is fine.

 

wow you have 10T of space on your PC...impresive what raid config are you using

[UltimatePlantDesignSuite - WinXP64pro (I know...IT dept is gonna go to win7 one of these decades) HPz800 - XeonX5690 @ 3.47GHz (stupid IT dept with there 12 core cpu's) - X58chipset (i aske for x78) - 24GB ram - quadro5000 (i do a lot of autocad3d aswell so opengl helps for that) ]

 

I ussually do the server maintenance as a seperate issue

working on large assemblies live on the server is not a good way to work. thats why autodesk recomend vault...your working on the local files...as long as the server is maintained properly you shouldnt have to wait too long for check in check out at the start/end of the day

I see that you have a very good work ethic and diligence. Unfortunately, that's rare :smileyvery-happy:

 

I'm not running any raid unfortunately, most of the drives came from other computers and were already formatted and contained valuable data. I also don't have enough free space to consolidate the data onto one or two drives, so that I can create a raid on the remaining drives. Besides, running raid 1 reduces available drive space. I'd like to be running raid 5 or 10 with at least 4 drives, but the costs involved are prohibitive ATM.

 

I do plan to add another 2 x 3TB drives in the near future and I will setup a few raid volumes then, but for now I have to live with it :smileysad:

 

I do have another two machines handy, but their drives are near capacity as well. :smileyvery-happy:

 

Do you know of any inexpensive drive hosts, raid capable or not, but able to handle 8 drives plus?

I'm not convinced that hardware is the solution to crashing issues.  With a 32-bit operating system, we are in a serious memory pinch, and run into yellow and red zones regularly, but crashing is not an issue.  Up to date drivers and a well-configured system (don't ask me to define that!) seem to be most important for Inventor stability.

Re: Autodesk Inventor PC Recommendation

We were running a Dell Precision T5400 with 4GB of ram on a 32 bit system.  I can't remember the exact processor but it was an older (2008) xenon model.  Honestly the thing crashed all the time.  Our assemblies have about 700-800 parts.  We did the 3gb switch (search forums for details) and it helped when using Inventor but robbed the system of too many resources.  When trying to take a screenshot of inventor windows would give a "not enought memory to paste to clipboard error".  It didn't leave much room for multitasking (outlook, excel etc.)  Finally we bought a new computer from the dell outlet center and it's working without any issues.  It was refurbished but here are the specs:

 

Optiplex 990

8gb of ram

i7 2600 processor 3.4GHz

Stock graphics card: In fact this is the lowest rated item in the windows experience score.  (I haven't had any problems though)

 

The i7 performs great.  FEA calculations are quicker.  I'm still using Inventor Professional 2010 but I've got to assume that 2011 would perform at the same level.

At no point has anyone on this thread suggested that hardware is the be all and end all of crashing issues.

Poor hardware configuration is DEFINATELY one of the causes of system instability and poor performance.

So too is the OS

So to are the drivers

and your pc config

and the modeling methods you employ

AND your pc maintenance

 

I have not used 32bit windows for engineering or cad for several years. (XP64, Vista64, soon Win7-64bit)

Even my kids pc's are 64bit.

The cost of good hardware these days is very insignificant compared to the software costs and hourly rates demanded for using these high end drafting solutions.

You can build an excelent Inventor machine that will handle large assemblies for around 3 grand.

Compared to the 10 or 12 grand you will pay for a machine that will run autocad3d to any ability.

For a definition of a well-configured system try reading through some of the white papers on large assembly performance....
