Benchmark

[Jayson Kramer]

Well I am getting Quoting from Solidbox to by my new computer.I will be looking forward to see how it will do..Will post and I must say they have some good deals.

He says this (mcam) won't take advantage of a Tesla cuda-based machine. Too bad.

What have I been saying this whole time! Abandon the cpu and move it to GPU. CUDA or OpenCL!!! But what do I know about computers :rollseyes:

 

cnc software, if you want to make mastercam fast, look into CUDA based threading or Open CL based. Then we could take advantage of tesla/fermi as computing cards or just use the ones we have in our comps!

[Steve Hattori]

Does anyone know which cad/cam package DOES allow use of the Cuda-based computing?

Best I could find in a cursory search.

Hi all!

 

I found an easy way to significantly improve calculation times on i7. My original time was around 1:30 with my i7 model 920, but I was able to get 1:13 by changing the default BCLK (aka. base frequency) from 133 MHz to 200 MHz. As I understand it, this one setting affects memory, CPU and BUS speeds. Basically my processor went from 2,7 GHz to 4,2 GHz.

 

 

These setting are machine specific, so you need to google or test the right setting. And of course you can get even more by changing voltages etc, but that is more complicated and it easier to break something. When I tried with custom voltages etc, it toke over two minutes to complete.

 

We tried this on Reijo’s i7, which is model 860, and there 180 MHz was too much. We settled for 150 MHz, even though it probably could take more. The original time was 1:48 and with the change, it was 1:32.

 

Some motherboards, like mine X58M, have this ability to test the highest setting automatically. In my case, it didn’t work, but it should be the safest way, so you should at least try it.

 

Here’s my hardware:

Intel i7 920 over clocked to 4.2 GHz

MSi X58M board

6144 MB of DDR3 memory

NVIDIA Quadro FX 1800

Windows 7 64-bit

 

I also changed the Affinity settings from the task manager, since for some reason, the default for Mastercam in my system is only one core. With only one selected, it calculates 50% slower, since it using, one core. So by clicking the Mastercam.exe, from the process-menu, with my right mouse button, I can get to the affinity settings. There I can choose that Mastercam.exe can use all cores.

 

Edit:

I would also like to add, that the multi-threading didn't make any differense to the calculations. The time was the same.

I'm having the same problem. I asked for a solution here:

But so far no reply.

BE CAREFUL OF THOSE SETTINGS!!!!!

 

If you have a stock cooler you WILL KILL YOUR PROCESSOR!

 

I have OC'd all my comps and that is just a dangerous frequence setting. Watch your temps.

[Eki Tossavainen Zenex Computing Oy]

As I understand it, my i7 doesn't have a temperature meter. The temperature is calculated from voltages and some other integers. When the calculated value reaches 100, the processor starts to drop the multiplier to slow down the processor and keep the calculated value under 100.

 

In my tests, this really hapens. After several minutes off full load, the temperature integer value get's to 100, and the multiplier drops.

 

But a better cooler could not hurt.

Inb4 the release of magic smoke.

 

Make sure you have your temp limits set to shut it down at 90 degrees C.

My T3500 came in today, and the benchmark was the first thing on my to do list.

 

I spoke with Mike Debutts earlier this week about a Solidbox system, but I couldn't wait 3 weeks for a new box.

 

My laptop finally bought the farm, and as you can see, I have a stack of new jobs and rev changes on my desk. There are 2 more stacks that go with that one.

 

I found this on the Dell refurb site for $2500 with the monitors included.

 

Dell Precision T3500

Xeon W3570 3.2Ghz 8M L3 6.4Gts

4 Gb ECC DDR3 @ 1333 Mhz

768 Mb Nvidia Quadro FX1800

300 Gb 10,000 rpm Velociraptor 16Mb Cache

Windows 7 Professional 64 bit

Dual P2210 22" Widescreen Monitors

SpacePilot Pro

 

So far I love it.

 

I'll bump the memory to 12 Gigs and add a second Velociraptor in a couple months and benchmark it again.

 

 

Meh new box:

 

 

 

Respectable time for a $2500 setup.

 

[Steve Hattori]

Good deal, with the monitors- a nice Intel SSD would prob get you under a minute...

[Jayson Kramer]

Mastercam Guru I do not see any of the options in the outlet that includes monitors for example were did you find this?

[Rob @ Target Machine]

Jay - You can buy the monitors when you check out.

 

Rob

[Jayson Kramer]

Cool thanks

[Rob @ Target Machine]

Jay, I just noticed that there's a pulldown tab labeled "stockrooms". That's where you can look at the available monitors.

 

I had to get the display port cables from Dell. You would think the refurb site would sell them with the monitors.

[Jayson Kramer]

I agree that is strange did you have to pay extra for them. I know I have about 8 or more of DVI and VGA in the garage. but it should come with them.

[Rob @ Target Machine]

It came with vga and dvi cables, not dp cables.

 

The FX1800 card has 2 dp out and one dvi out.

 

I know I could have gotten an adapter, but I figured the 2 dp cables would be a more stable choice for dual monitors.

 

[Chris Rizzo]

Wow, my $1000 rig is a real snake in the grass still:

 

 

 

 

 

Only running at 3.7, and pretty low voltage and temps I believe. Have'nt done anything at all to this, other than use the handy little oc screen in the bios.

[Rob @ Target Machine]

I just installed my second Velociraptor today and set up raid 0 through the Matrix onboard raid control and only see a second or two gain in the benchmark.

 

Is this all I should expect? Should I format and reinstall?

 

Everything says that the array is working properly, but in windows disk management, it is still recognized as a simple volume, not a dynamic or striped volume. I'm guessing that's because the raid array is controlled by the bios.

[The_Evil_Machinist]

Buy a raid card. BIOS level raid is software controlled so its honestly a placebo. You will not get that mush speed improvement from it. It's better for raid 1 setups.

 

Buy raid card

Backup all data

Install it/hook up drives

Setup raid 0

format

reinstall everything

[Rob @ Target Machine]

Thanks Evil. I'll order a SAS6/iR card this afternoon.

I was very surprised at how fast this processed so I ran it again, 1st with differeent tolerance, then again with .0001 tolerance...same result as before 5 min. 39 sec.

[The_Evil_Machinist]

Just received an update to VMWare virtual machines so lets see if I can get my benchmark record back!

 

Gotta fix my cluster and rewrite my Xgrid virtual machine scripts. Good way to kill the rest of the day

[The_Evil_Machinist]

18 secs. Gettin there...
