Rendering Workstation

webadmin@intel.com — Tue, 21 May 2013 17:43:33 GMT

Hi all

This is my first post so hope it will be answered, i'll try to make a simple one. Basicly I do renderings of an interior/exterior scene using Win7 64 bit and hp z800 with 2x Xeon E5530 @ 2.40 GHz cpu with NVidia Quadro 3800FX graphics card, and 16gb ram. With 3DS Max Design 2014, Vray2.4 addin it takes up to 10hours of calculation for a complex scene in HQ at 3000x3000 pixels. What I want is to use Dual Xeon E5 cpu with 32 or more ram with a gtx titan or Quadro 4000k graphic card and fasten this process. Has any one got any idea or better suggestions for this issue, or anyone uses a computer like this or better one? Any idea about Xeon phi coprocessor can be a better solution?!? It would be work in a workstation to improve speed in the rendering process?!?!?

Tnx.

Salve a tutti,

questo è il mio primo post e spero che qualcuno possa rispondermi, quindi cercherò di spiegarmi bene. Di media sviluppo renderings di interni ed esterni utilizzando una workstation HP Z800 con sistema operativo Win7 a 64 bit equipaggiato con: 2 processori Xeon E5530 @ 2.40 GHz, scheda video NVidia Quadro 3800FX, 16Gb di ram. Il software di sviluppo che utilizzo è 3DS Max Design 2014, Vray2.4 e per il calcolo di una scena complessa ad alta qualità e risoluzione a 3000x3000 pixels impega di media 10 ore di calcolo. Vorrei passare ad una nuova WS equipaggiata con doppi processore della serie Xeon E5, con 32 o più gb di ram, con scheda grafica GTX Titan o ancor meglio una Quadro 4000k per aumentare la velocità di sviluppo. Qualcuno ha una migliore soluzione o consiglio? Affiancare un coprocessore Xeon Phi potrebbe esser una migliore soluzione?!? Funzionerebbe installato su di una WS per diminuire i tempi di calcolo relativi al processo di render ( CPU based ) ?!?!?

Grazie.

q6600 testing

webadmin@intel.com — Mon, 20 May 2013 16:58:12 GMT

i am having random reboots and i have been trying to cover all my bases my 4 core temps without any real load sit in the 90F-100F range i have within he last 6 months gotten a corsair h60 on sale and i cant tell if thats doing anything but thats another matter .... what i need to know is how to test and understand the results of whatever tests i can dso to see if my processor maybe the cause if trhe restarts .... yesterday i got a new psu from 520w to 750w and still the same i run hwmonitor constantly to watch temp on everything and such i used to also watch the windows performance readings those i understood basically but this may all be getting out of my realm ....

basically i need to cross off things that are not the cause ... what i am presently running with is

Motherboard XFX Nforce 680i LT (Socket 775)

Processor Intel Core 2 Quad Q6600 @ 2.40GHz

Optical Drive PIONEER DVD-RW DVR-215D SCS

HD1 WDC WD50 00AAKS-00A7B SCSI

HD2 WDC WD20 EURS-63S48Y0 SCSI

RAM 4.00GB Dual-Channel DDR2 @ 399MHz (6-6-6-18)

Graphics Card XFX Nforce 680i LT (Socket 775)

and the current read outs are as follows during the time writing this and just speccy and HW monitor open plus webpages

core 0 96F

core 1 100F

core 2 93F

core 3 98F

graphics card 143F

HD 1 118F

HD 2 111F

cputin 109F

auxtin 116F

to be clear i will also be doing more research on the graphics card as well i have been getting these exact cards for like 100 a piece and this is the second after my original they seem to last about a year but i think that might have something to do with the underlined issue here and this random rebooting is a new addition to the same possibly

if anyone has any other information that could be of use in any regard of any of this i would be grateful

Please help

Hi Intel

I have bought Intel Xeon E3-1220 v2 processor.

I am testing Linux PREEMPT-RT on this processor. I created a test to see the time it takes for the OS to handle the clock tick.

My test is as following: I create a thread with highest priority ( can be preempted only by interrupts), whose task is just to do a small calculation in a loop of 45000 times. This task takes 102 µs to be finished.

If a clock tick happens while the task is executing, then this task is interrupted for some time until the interrupt is handled. ( aka: in normal case, the task takes 112 µs and if a tick happens, then the task takes 120 µs, which means that 8 µs are spent by the OS to handle the clock tick interrupt). I did this procedure around 100 times and I saw that each 1 ms I got a clock interrupt as the OS clock tick is running at 1000 Hz. so the normal values should be 102 µs if no tick happens, and 110µs if a clock tick happens.

This was perfect test on Intel core i7-930 @2.8GHz.

If I do the test on processor Xeon E3-1220 v2 @ 3.1 GHz, the task takes shorter time ( 102 µs) as it is faster processor 110 µs if a tick happens.

The strange thing I see on this processor that sometimes I get values around 120 µs, which means that some kind of interrupt happened and preempted the task for 18 µs. If it was clock tick, then it should take 110 µs.

so the processor is generating some kind of interrupts.

If I do the test with loop of 5000 instead of 45000, I do not see anymore such strange values.

Synthesis: if I do a task which is looping 45000 times on intel xeon, I start to get strange interrupts, which is not the case on i7-930.

If I do the test with loop of 5000, the interrupts disappear.

what could be the issue?

Problemi legati all'alimentazione processore core I7

webadmin@intel.com — Mon, 13 May 2013 17:09:21 GMT

Hello from Luciano to all staff Intel corporation

I propose my question to your Staff because i have any problem with my acttually processor model previous mentioned

because i've bought an power supply to plump my acctually mother board model Zotac Z77 .

This Mother Board has Lg1155 socket for positioning this processor but my actually power supply can't deliver enaught

current for 3,3 V alimentation.

Now this power supply can only deliver 8 A current over this alimentation , i think isn't enaught to work this processor in full load.

I Propose this question because this processor now work properly but when i load a strong application that necessary a lot of resources

and elaboration suddenly turn off

I would like grateful if your personel can explain me how many WATT is necessary only for this processor to work properly.

Now i have an power supply can erogate 160 W but only 8 A over 3,3 V for this reason when this processor work in full load

require more current and then turn off my station , i think this power supply enter into protection mode because when i try

another IPL this station turn off again , for restart normally situation is necessary about 15 minutes off.

Can any one help me to resolve this problem ?

THank you very much !

Hello, i5 3570k Power question

webadmin@intel.com — Fri, 10 May 2013 13:39:14 GMT

I have a MSI Z77A-G45 motherboard.

This board has an 8-pin CPU power connector.

My PSU does not have this cable (it's "old")

Do I need to plug this cable? Do I have to find an adapter cable (or buy a new PSU) ?

Thanks

Intel Xeon 5130

webadmin@intel.com — Fri, 03 May 2013 19:55:58 GMT

Hi:

I have a Dell Precision 690 that has two 5130 dual core, processors on the motherboard. AT 2.0Ghz, they are getting slow.

The one at work, same model has two quad cores at 3.2 Ghz which makes a difference. Both run 8 GB or RAM.

Without cannibalizing another machine is there a processor(s) that anyone would suggest to replace these units? Yes I'd like to replace both of them. Makes more sense.

Thanks kindly

Intel cooling solution RTS2011LC - possible to get spare parts?

webadmin@intel.com — Fri, 19 Apr 2013 22:20:57 GMT

Hi,

I recently tried to move my Intel RTS2011LC from a socket 2011 to a 1155 motherboard.

To my regret, I discovered, that the thumbscrews attached to my mounting bracket do not fit in the new board.

Upon inspection of the manual, it became clear, that i need a different set of thumbscrews to use with socket 1155.

Unfortunately these screws did not come included with the PC, I had bought with the cooler in it, so now my question is:

Is it possible to obtain a set of thumbscrews as spare parts somehow? Btw. I live in Denmark.

Thanks in advance for any help!

Quad Node system Processor selection

webadmin@intel.com — Wed, 17 Apr 2013 17:03:55 GMT

In reference to R2208LT2HKC4 Quad Node server 2U system, can I install two E5-4620 processors and at a later time install two - E5-4650 processors? If this is possible, what are the negatives to a configuration with mixed processors as described above or the justification & benefits of the E5-4650? I thank you in advance for your contribution.

3930k only using 6 threads?

webadmin@intel.com — Wed, 17 Apr 2013 06:39:04 GMT

I have a 3930k , it's supposed to have 6-cores and 12 threads, but in CPUID and task manager it says my processor only has 6 sixs and 6 threads?

Are these programs lying , or do i need to activate the other 6 threads somewhere?x

Question about i7-2600k & EPT

webadmin@intel.com — Tue, 16 Apr 2013 23:27:29 GMT

I am thinking about putting windows 8 enterprise so I can support Remote FX, I have a compatable graphics card, and according to intel's information at this link

ARK | Intel® Core™ i7-2600 Processor (8M Cache, up to 3.80 GHz)

my processor support EPT which is needed to support remote FX. However, when I run the intel processor ID utility is says it does not support either virualization technology or intel VT-x with EPT? I included a screen shot at the bottom. I am running an mobo with the Z68 chipset. I have the virtualation tech turned on in the bios, and I am running the latest bios update that supports Windows 8. Can anyone tell me why when Intel says my processor should support it, but their own utility tells me something else?
