quad socket amd opteron 6128

[tridiseny]

hi ,
good morning, I am thinking of buying a new workstation for my studio. I've thought a Tyan motherboard with 4 sockets to mount 4 AMD Opteron 6128 (8 cores per processor) with 16GB of RAM per processor. The operating system you use will be windows server 2008 enterprise. My question is if Vray have any limitation with the number of processors or the number of cores and I have not found information with 4-socket workstation. Now working with dual xeon and I have no problems and wanted to know if it worked all right.

Thank you very much. Greetings from Spain.

hmm good question !! i want see vlado s answer coz i am waiting for it looong time ..... (had quad amd rig and up to 8cores see no scalability of vray )

heh but answer is not in that thread coz saying nothing about SOCKETS and your future mobo will have 4 sockets, i got older model of tyan quad amd (4895-e) and got problem with procesor scaling but only with vray ( MR , fryrender, maxwell is ok )

uffff, I was quiet thinking would work well 4 sockets and now I doubt, next week I have to buy the new workstation.

Janosik, your problem is not solved with new versions of vray?
What operating system you used?

[iTiunov]

We have both AMD and Intel quad socket platforms. Work well till number of core goes beyond 64...

Thanks Itiunov,
then the scalability of processors is correct, everything works 100% if the server does not have more than 64 cores. Well, I'll buy that motherboard with 4 sockets instead of having 2 dual motherboards ..

[iTiunov]

One moment. To utilize more than 2 sockets U'll need Windows Server 2008 cause Windows 7 limited to 2 sockets.

I'm going to use windows server 2008, 2011 and vray 3dmax 1.5 sp6

well i can doubt about scalability of vray on amd cpus , can you show renders with 1 ,2 ,4,8 16 ,32 ,64 cores please ? i mean the same scene same resolutin only different number of cores .

[tridiseny]

Hello Janosik , although i dont have the new workstation. I think that in one or two weeks i will have the new workstation. The vray distribution in Spain said me that scalability is correct, all core to 100%.

sounds like a fat workstation. however i have a question.. why spend so much to get a quad mobo and 8 core chips? surely for that price (must admit i dont know price of those chips and mobo but cant be cheap) you could buy a more standard workstation and 5 - 10 rendernodes to distribute to.. would be a much faster option id imagine. whenever i see people buying top of the line multicore cpus that cost as much as 3 normal machines, i wonder why...? do you have other software that will use 32 cores but cant be distibuted?

You're 100% correct when it comes to Xeon Quad socket systems (MP) but Opteron 6180 cpus are only $250 each. Four of those will cost you less than a single Xeon X5650!! Opterons are only really competitive with Xeons when you go with quad sockets.

well blimey.. i didnt know that. intersssting. and the motherboards?
