Those of you stuck with 64-bit XP or Server 2003 need not apply. Performance and Virtualization 64-bit versions of operating systems such as Windows Vista and Windows 7 are not automatically faster than their 32-bit counterparts. Conclusion The addition of a 64-bit version of Office 2010 enables you to move more data around for increased capability. There is a well-known problem regarding SVD.

These variables now truncate 64-bit values returned by API calls when using Declare statements. It can also indicate the sizes of types involved. Advertisement If you're running Mac OS X, you don't need to worry about 32-bit vs 64-bit, and if you're running Linux, you probably know this stuff already.

But if the 64-bit version uses twice as much RAM...that would be something that would concern me.

August 5, 2014 Jacob Mastel wilsontp said: But if the 64-bit version uses More often than not, the maximum size of the physical memory on a computer is less than the amount needed for all running programs. 32 Bit Vs 64 Bit For example, my primary VSs are VS 2005 and 2008 and it takes just a couple tens of seconds to compile some small test project from the command line without overheads Returns a LongPtr on 64-bit versions, and a Long on 32-bit versions (4 bytes).FunctionStrPtrString converter.

Windows expert Mark Russinovich found that a desktop running 32-bit Windows with 4 GB of RAM and two 1 GB video cards only had 2.2 GB of RAM available for the vs. 11.0 update 4 2. Alternative symptom is * * a loop in module HPCAE150. * **************************************************************** * RECOMMENDATION: * **************************************************************** Bits 0-31 of registers 14,15,0,1 were not being restored in 64-bit processing mode. I will attempt to have another at my company respond in my absense.

Summary Windows 7 x64 Edition represents the first mainstream 64-bit operating system from Microsoft in terms of general availability and support from third-party add-on vendors. After compiling the MKLconsole.sln, you will need to copy the mkl dlls to the \x64\release or \x64\debug directory. You should use these functions to retrieve pointers to strings, variables and objects, respectively.

It seems quite strange to us that performing the same series of tests within one application run results in such drastic changes in the time required to peform these tests.  We You can only install 64-bit Office 2010 on a sufficiently updated 64-bit Vista, Windows 7, or Windows Server 2008 machine. You can assign numeric values but not numeric types (to avoid truncation).Conversion OperatorCLngPtrConverts a simple expression to a LongPtr data type.Conversion OperatorCLngLngConverts a simple expression to a LongLong data type.FunctionVarPtrVariant converter.

Native 64-bit processes in Office 2010 cannot load 32-bit binaries.

Yes. Most of your Windows programs aren't taking advantage of the 64-bit architecture. Your feedback about this content is important.Let us know what you think. Back to Top 5.

But 64-bit Programs Would Be Better, Right? This article discusses issues around the compatibility of the 32-bit version with the new 64-bit version and legacy 32-bit Office applications and their solutions. (7 Printed Pages) Last modified: April 24, However, when you write 64-bit code, you should ensure that your code contains specific keywords and conditional compilation constants to ensure that the code is backward compatible with earlier version of For code that is different between the 32-bit version and the 64-bit version, such as calling a math API which uses LongLong for its 64-bit version and Long for its 32-bit

For 64-bit version of Windows, Microsoft also requires a digital signature on all drivers. VBA Copy Declare Function RegOpenKeyA Lib "advapi32.dll" (ByVal Key As Long, ByVal SubKey As String, NewKey As Long) As Long The Windows.h (window handle) entry for the RegOpenKeyA function is as Back to Top 7. Application Programming Interface Compatibility The combination of VBA and type libraries gives you lots of functionality to create Microsoft Office applications.

Interesting! [edit] Turned that into a quick article for tomorrow.

Got Feedback? Get geeky trivia, fun facts, and much more. However, 64-bit Intel and AMD processors are backward compatible and can natively execute 32-bit software. Until recently, almost all consumer PCs used 32-bit processors.

Not every application stands to benefit from the x64 architecture, and it will take time for 64-bit editions of Windows to gain widespread adoption, but the following types of applications are Upon profiling the application, the location of the slowdowns, seems to stem from the ZBDSQR call in the function below. NA:MA), SIZEU=MA*NA, SIZEVT=MA*NA, INCX=1, INCY=1, KU=NA, KV=MA; double *RWORK, *D, *E; complex *WORK, *TAUQ, *TAUP, *C=0; int charlen; RWORK=new double[4*NA]; D=new double[MA+NA]; E=new double[MA+NA]; WORK=new complex[LWORK]; TAUQ=new complex[MA+NA]; TAUP=new complex[MA+NA]; //zgebrd_(&MA, The solution for this is that programs store some of their data on the hard drive and copy it back and forth to physical memory as needed.

A 32-bit processor can reference 2^32 bytes, or 4 GB of memory. It is only supported in the VBA 7 runtime on 32-bit and 64-bit. Rather I found this from your website http://software.intel.com/en-us/articles/recommended-settings-for-callin... If you're using a 64-bit version of Windows 7, you'll see "*32" instead. 32-bit programs are usually installed to the C:\Program Files (x86)\ folder on 64-bit versions of Windows, while 64-bit

Do you have a clue of how big the performance improvement will be or if there are some benchmark results available?  Thanks.

Top Log in to post comments Ying H. Use the task manager to see which of your programs are 64-bit and which are 32-bit. Between the two runs, we svd 15 rectangular matrixes of different dimensions (R_SVD).  Here is the result I got, you can see the performance of lasvd and gesvd slows down ~50% I can run it now.

For example, on a Platform A with some CPU ( non AVX-like ) a SSE4 CPU dispatching DLL was used and on a Platform B with some CPU ( AVX-like ) Some programs do offer 64-bit versions.
