geez if you can't take a simple tube with 8 bolts off best get help.

Thank you. I work in IT and am not a mechanic. I haven't even looked under the car at the propshaft yet, nor looked in RAVE. I've only looked at a leaking half shaft seal. If it's only "a simple tube with 8 bolts" then yes, of course I'd cope but for all I knew, it would need special tools or something else might need removing to get at it etc etc...

However, I do feel the same as you when people ask dumb IT questions :)

Ok heres a dumb IT Question for you....

Why is it that even though I have a mega machine with 24 Proccessing cores (4x Xeon X5650 Hex Core CPU's), 24GB of RAM, Twin SLi'd Nvidia Quadro 4000 Graphics Cards with 2GB DDR5 each - My Render times are so fecking slow even if I pass the Render information through to the CUDA Cores on the GPU's and use the CPU to process the Light Pass calcs in other words, I am using all 24 cores to calculate lighting information, the GPU Processors to render the final image and the CUDA Cores to process the shading it takes an age to render anything...???

(I am a design Engineer who specialises in 3D Concept modelling, Mechanical Design and 3D animation - hence the hardcore machine)

Screenshot of the Desktop to show the Processor and GPU information attached (personal items in my emails blanked:D)

Bit better than a Commadore 64 then? :p:p
 
Another screenshot to put it into context.....

(I didn't do the whole model - my bit is part of the combustion chamber - not senior enough to take on a whole engine yet) - but I do create the 3D artwork and Concept designs once the whole engine is finished!

Our IT guys melt when I ask them a question - its as if I have just spoken to them in Klingon!!

Anyhoot back to your problem.....sorry for thread hijack!!

Change operating system and consider a Beowulf cluster. Think that's how they do the complex CGI stuff for movies.

Just out of interest, are you using SSD? If not, that is why it is taking so long to render. HDDs are a massive bottle neck in modern systems, even the 15k drives are a huge bottleneck, not to mention massively costly. Although a SSD has a finite amount of times it can be written to, for what you're doing I imagine you don't hang onto a single machine for over 5 years so would never become an issue.

We do rent Render Farm space as our IT gurus(?) won't fork out for a Nvidia Tesla Farm or even as you say a bunch of standard workstations networked running a render suite of some description....tight ass monkeys - they baulked at getting the one mega machine for final renders....

When I asked about Solid State Drives they shrugged and stuck in a pair of Seagate Barracudas that only have a 10k spindle speed in it - we pull most information of the netwrok servers they said - when I tried to explain the render process - they glazed over and then mumbled something about cost/benefit analysis quotas etc and sulked off....

I think my biggest bottleneck is the motherboard and HDD's but it is only just over a year old now and slowing down already....but it is on 24hrs a day 7 days a week rendering and calculating - plus running Landyzone !! :D:D:D
 
My son goes to Uni and is studying gaming and (in a much lesser way) had similar issues. So when he got home we linked together 6 desktops at home and 'a few' at school to use overnight as a render farm ... can't remember what software but it was brilliant and completely transparent. Using Adobe Maya took scene renders down from 8 hours to 3 frames an hour .. which also allowed him to make minimalist animations .. and these were/are only single core 'normal' pc's ... ;)
 
Speaking of MPG (back to the original post) Removing or blanking the EGR valve will only give you a pooftenth more MPG and not really noticeable. What you will notice is…. response off the line is improved! Less smoke out of the back!

MPG….. my trip computer hovers around 27mpg I work 40 miles away from work and I don’t use it around town very often, but 16mpg is shocking? I managed 25 with boot full of camping stuff and 5 people in the car – A/C on all the way – ipads charging – phones plugged in etc travelling at a steady 70mph (give or take)
 
I'm surprised Sony haven't latched on to this (Perhaps they have). When you see what a PS3 can do for a couple of hundred quid, imagine what they could come up with using their experience and a couple of grand. I suppose the market is too small to warrant the investment.

Sounds like your IT guys need sacking. Without having fibre from your workstation to the server, the best speeds you can get is 1gig network, which assumes an empty network, couple that with how hard the server will be hit, the read/write times will drop faster than a priests underpants in Sunday school. That is a **** way to do things.

If you're running to and from the servers without saving the render locally, then you'll never have speedy renders times, plus the server will always be overloaded and your network will suck as I assume you've got an office full of people all doing the same thing, day in, day out.

Your board will be a slight weak point but given your hardware requirements, you will struggle to find anything that can do a better job. Keep the BIOS up to date as new revisions come out quite a bit which improve performance.

For cost reasons, I can see why someone would choose to stick to platters. When you can get 1TB for less than £90, it is hard to justify 120GB SSDs at the same price. As our company deals with servers rather than workstations, we're normally comparing costs to 15k SAS drives and SSDs look cheap in comparison.

Oh so very true - thankfully I am the only one who does the hardcore rendering - but the other bods in the office do do 3D modelling and design work - it then comes to me to render and animate as necessary once I have finished my design work!!....

I do Render local, and then once every 90 seconds it uploads that render pass to the server whilst the render engine completes the next pass to the local machine, then shots that pass back up the pipe to the server again 90 seconds later.

Our IT guys are total feckwits, but nice enough guys themselves, I guess they are only working to 'Corperate Guidelines' - we are an engineering company primarily and just a sub-contractor to a much larger manufacturer - when I joined, I started to push them towards 3D artwork and Concept renderings, as all they did previous was 3 view flat 2d Drawings, and I pushed to get them to do proper visualisations to better represent the products to customers, they are slowly coming round to the idea as we have had some good feedback - but they still don't consider it part of the 'Core Business' so I guess I am lucky to have the machine I do, and shouldn't push to hard for them to spend mega bucks on equipment as much as I would love them too!!

As for MACs - Girlfriend uses them day in and day out, but when it comes to 3D work nothing beats a hardcore PC based system - not even a top job MAC - Leave them to Photoshop and After Effects...!!

I'm sure when some boffins worked pi out to 1million decimal points, they used a load of ps3 joined up

Would explain the setup then, standard corporate procedure means nothing can be saved to a workstation as they aren't backed up. All work must be saved on the server. It is something we find hard to get SMBs into the habit of doing, too many people think it is their work and not the companies.

The best solutions to your problems mean investing cash and I suspect you'd get slapped with a wet trout if you started asking for more toys to play with. A simple solution would be a SAN device for your office, but a "cheap" one starts at about 3 grand. :p

I wouldn't go as far to say Macs are good for Photoshop, that is just good marketing by Apple. Up until recently Adobe have been making Photoshop for Windows and then porting it over to MacOS. After the fisticuffs Adobe and Apple have been in, it wouldn't surprise me if Adobe go back to porting the Windows version back over again.

Folding@Home use idle PS3s to help with their project. Calculating Pi to 1million is a nothing job though. A modern PC could do it in under 10 seconds. My old Athlon 64 3000+ could do it in 36 seconds linkage. It was a common benchmark used by Overclockers to calculate Pi to 1m. SuperPi is your friend. ;)
 
Could of been a trillion then, :confused: it was some land mark , I'm sure linking pc's together would of been better, but I use spanners not computers , so am a not thick when it comes to computers :eek:
 
Quite possibly trillion, the chips used in the PS3s are outrageously powerful and are mostly wasted. I suspect daisy chaining PS3s rather than PCs was a PR stunt by Sony to profile how powerful the hardware they've used to make the PS3 is.
