64-bit Edition To Support Over 64 Logical Processors
Dec 28, 2008
"Windows 7 will be able to take advantage not only of faster CPUs, but of multiple processors on a single chip. The 64-bit edition of the operating system in particular will be able to support over 64 Logical Processors per machine.
In this regard, Microsoft underlined the need for software developers to adapt their applications in accordance with the evolution of processor chips and that of the Windows operating system.
Essentially, consistent gains in performance are synonymous with using parallel programming techniques in concordance with many-core processors. This is where non-uniform memory access (NUMA) comes in.
“The 64-bit versions of Windows 7 and Windows Server 2008 R2 support more than 64 Logical Processors (LP) on a single computer,” Phil Pennington, Windows Server Technical Evangelism, revealed. “New processors are now appearing that leverage non-uniform memory access (NUMA) architectures.
Within the near future, a system with 4 CPU sockets, 8 processor-cores per socket, and with Simultaneious Multi-Threading (SMT) enabled per core, will achieve 64 Logical Processors. Many server-class solutions will need to be architected with NUMA awareness in order to achieve linear performance scaling on 64+ LP systems.”
NUMA is a designed to allow a way around the limitations of the processor bus. Because of its non-linear characteristics, each processor is more intimately connected with its proximate memory, rather than with all the memory available. Unlike the Symmetric Multi-Processor (SMP) model, in which processors are all on par when it comes down to memory and I/O access, NUMA allows for memory access optimization.
“There is nothing the matter with NUMA – machines with non-uniform memory access speeds – of course, other than the fact that they introduce complex, hardware-specific programming models if you want to build applications that can harness their performance and capacity effectively.
What is decidedly new is the extent to which previously esoteric NUMA architecture machines are becoming mainstream building blocks for current and future application servers. For the connected applications of the future, our ability to build programming models that help server application developers deal with complex NUMA architecture performance considerations is the singular challenge of the many-core era,” Windows Performance Engineer Rick Vicik explained.

It seems some of the most advanced Intel Processors doesnt support XPMode
for eg: Core 2 Quad Q8200 and Core 2 Duo E7400 wont support XPMode
so here is complete list of Intel Processors(both desktop and Mobile) that support XPMode:
Desktop CPUS
Core 2 Duo
E4300/4400/4500/4600/4700 NO E6300/6320/6400/6420/6540/6550 YES E6600/6700/6750/6850 YES E7200/7300/7400/7500 NO E8190 NO E8200/8300/8400/8500/8600 YES
I would like to ask this straightforward question: does Windows 7 Ultimate Edition support both 32 and 64 bits? I have a legal copy of it and installed it on my Vista Business PC, but it seems to be running at 32 bits only. Is it because of this Vista only supporting 32 bits? How do you tell the bits your OS is running at?
I sometimes buy batches of used computers from companies to resell, and today someone called me and offered a deal.He was offering some servers using the 5000-series chipset (vague, I don't know the full specifics atm), that supports two processors.The processors installed atm are two Intel Xeon E5345.Now, I looked at benchmarks about them and they are around half of most of the top ten CPUs apiece.I doubt the score doubles if there are two processors of the same kind, but I really hope it does.Also, assuming it has a PCIe 16x (the 5000X chipsets do, don't know if this is X or not), will games run well on a rig like this if I slap a good card on it? Or the fact there are two different processors prevents games from using the second's processing power, or somesuch? (like it was for older games designed for single cores when running on dual cores)In the past all servers I found were too damn crappy to do anything else than what they were designed to do (sit in a server rack and do something boring 24/7), so I have little experience in re-purposing them.

I am new to Windows 7 and I have a question that I need an answer to if at all possible.I was told there is a way to force a program to use all of my processors and Ram memory. I need to figure out if this possible and what I have to do to accomplish this.I am wanting to force a video game to use all four processors and all/ more Ram memory than the game was designed to use. According the Game manufacturs/ producer I was informed to use Msconfig to set up this procedure and for it to work properly. Is this correct or is there a different way I can force this game to work better?
I tried installing a 64 bit Windows 7 on 32 bit processor(Dual Core, 2.80HGHz) having a DDR RAM of 2.5GB. But I could not do so due to 'Hardware Incompatibility'.I then tried to install a 32 bit-Windows7 Home premium, but again the same 'Hardware Incompatibility' appears on screen and prevents the installation.
I wanted to know if there was any way i could make windows 7 my only operating system. Currently i have a dual boot with xp and 7. On disk management xp is listed as D: (System,Active,Primary Partition) and 7 is listed as C: (Boot,Page File,Crash Dump,Logical Drive). Is there any way to delete windows xp and have windows 7 be the primary partition without reinstalling it. I already moved all of my data from xp to windows 7. I had hoped to delete all of the data on XP and incorporate the newly unallocated space into windows 7.
I've often heard that the OS should be on a drive (logical drive) by itself so that, when it gets a problem, you can just re-install a new copy of the OS on that drive. However, isn't the OS modified when you install programs?
I have 4 partitions...1 with 7, and another with Vista. I want to put XP on also, but of course I can't create another primary. I'm pretty sure I can add XP on a logical, but don't know how. Am I right, or am I out of luck with XP.
After clean installing Windows 7 to second partition dual booting with XP, I notice that the Windows 7 paritition is marked "logical drive" in Disk Management. XP is marked primary active.
Are there any reasons why an OS should not be installed to a logical drive?
I've bought this Sragate 500GB (Recognized as 465GB) HDD and moved everyhing into it. Partitioned it during 7 installation and here are my partitions all in NTFS:
Primary (101MB) - NTFS - Created during Windows 7 setup - I'll delete when I'm ready to install a new OS
I installed my Windows 7 and winxp in the 2nd and 3rd primary and I switch between these two by activaving the appropriate one. when I'm in XP and activate 75GB primart to boot in Windows 7 something strange happens:
Except the 1st logical drive, any other logical drive I have after it dissapears and turns into unpartitioned space. and it seems to be a bug of windows disk management tool or limitation in winxp. the point is that there's no such a problem when I do the same in Windows 7 exactly.
i had XP pro installed on my c drive (250gb) for a while,,,a month ago i have installed windows 7 enterprise to another hard disk (500gb) to test and get used to it while i keep my xp...so i have dual boot without any problems..
i never actually looked at it before up until today when i decided that its time to get rid of xp and keep the windows 7 as my only boot option...
as some of you have experienced before i had problems deleting the xp completely due to it being the system drive,etc..
while i was playing around i have found out that the hard drive that i have installed windows 7 has no primary partition but only a logical drive where the os is installed...while the hard drive of the xp is system drive on a primary partition...( I AM ATTACHING THE SCREEN-SHOT OF MY DISK MANAGEMENT)
so now i have a dilemma,,i need help!!
what i ultimately want to do is to get rid of XP completely and keep my 7 as my only boot.....what the heck do i need to do to accomplish that?
i have unsuccessfully tried to delete ,format the xp manually,,,i have physically removed the xp drive which resulted in no boot at all,,cause it has the boot file...
im stuck with a drive which i cannot format,,and if i do it , i cant boot windows 7...
1 thing i didnt try is to format xp drive with xp cd setup...it will result in no boot...and boot the pc with win7 cd and repair the boot sector....i don't know if it will work and i don't trust it...i dont want to lose my windows 7 setup as i have installed all my software and settings...
the fact that it is installed on a logical drive bothers me a lot! help?
My friend recently upgraded to 7 with my help. However i made the mistake of making it a logical partition. Once he deleted his old Vista partition, the system was unbootable. Now he needs a way to convert the logical partition to a primary one. I had him try use gparted live to convert it, but gparted doesnt have that option. My next idea was to run puppy off a USB and use a partition manager on that.
So, I want to have Windows 7 Home Premium 86x and 64x versions installed on my PC with dualboot. I have 86x version of Windows 7 installed already. So, for 64x version, I have to create a new partition. The problem is, I already have 4 primary partitions, so I can't create a new one (I read somewhere that Windows have to be installed on a primary partition). Here is the picture: (Don't mind disk 2, it's just the external drive).
If I try to create a partition on "Unallocated", Acronis Disk says this:
My question is, which of these partitions on disk 1 can I safely convert to logical? If I am wrong here and I still won't be able to create a new primary partition for Windows to be installed on. I'm really not so good at this things.
my 50 gb partition has become extended and i am not able to make it logical partion......it is showing that error "there is not enough memory to make the partition" can anyone tell how to de-extend the extended partition to make it unallocated memorry?
I currently have Win XP 32 bit on my C drive which is logical (don't know why it is). And I want to add Windows Ultimate, but I don't know where to put it. Here is a screenshot of my disk management.
Operating System Microsoft Windows XP Pro 32 bit Computer Model N/A CPU Intel Core i3-2120 CPU @ 3.30Hz
Windows 7 is coming pre-installed on my new PC from Dell. It has two 500GB HDDs.
I want to partition the first drive into just a couple of partitions. I guess I will have to shrink the main partition to about 100GB for the OS and apps.
But my question is: that partition with the OS and apps will be a 'primary' one...what will my next couple of partitions be? Logical? Extended?
I'm not sure how to decide what type of partitions to have.
Earlier in the year I bought myself an Apple Mac Mini. I knew I could run Windows on it and soon installed Windows 7. For various reasons I'd like to run 2 copies of Windows, plus OS-X, plus a shared FAT32 partition which all OSs can see and write to. You wouldn't think that would be so difficult..!Unfortunately, Macs use the GPT disk partitioning scheme (which doesn't support extended or logical volumes), Instead, it can support up to 128 primary partitions. However, these get presented to Windows as if they were MBR partitions. GPT also needs an EFI partition, giving me 5 partitions minimum for what I need. Windows backup & partitioning tools (e.g. Paragon's Drive Backup) mistakenly see this as an MBR drive with 5 primary partitions and subsequently refuse to work.Fortunately, Mac OS-X doesn't actually need to be on a GPT drive. It'll run perfectly well from an MBR drive which should in theory save me one partition (the EFI partition). In practice however, installing Windows 7 on an MBR drive causes it to create a 100MB System partition. This leaves me needing 5 partitions again which gets me right back to square one!Is there any way to configure Windows 7 so that it doesn't need that 100MB partition?
Just new here, i am right now installing my new-built PC with Windows 7 Enterprise.
Unfortunately, i have already some problems. My hard drive is a 1 TB WD and on setup i made a primary partition of 50 GB for Windows 7. I thought to partition the rest afterwards and there is the problem. The installation went without any problem, but in diskmanager i cannot see the option as i saw in XP to choose between a primary or an extended partition.
I wanted to make a large extended partition of the unallocated space and then divide it into some logical drives to hold my programs, pictures & films,... etc. As Windows 7 makes primary partition always i am limited to 4 partitions and that is not enough.
I have Windows 7 SP1 and I should only move the users profiles (without the default profile) and the public folder in a NTFS logical partition.
I should modify the ACLs of the root directory () of the logical partition to still have a coherent and stable system or not? If so, how should I modify these ACLs?
