Reduce False Sharing in .NET
dotnetraj at 10:27:25 am on
software that performs well in a single threaded environment do not always perform as expected in multiprocessor/multithreaded environments. There are many well known non-platform specific issues with multithreaded applications running on MP systems. One of the most well known issues is that the processor cache line reloads due to what is known as false sharing. These misses effectively undo the scaling benefits of adding additional processors to systems. It forces the memory subsystem to reacquire data into the processor cache for every memory load/store a worker thread performs on certain types of global data.
Unfortunately, the .NET framework hides most of the logic that would allow you to overcome false sharing in a native environment. Memory management, both allocation and garbage collection is handled inside the .NET framework with very little exposure for you. The .NET framework does this to keep up the promise of writing once run on many platforms. But, the tradeoff is a significant scaling and performance impact on your multithreaded code.
Take either of the following two possible approaches:
- Pad each thread's data element to ensure that elements owned by different threads all lie on separate cache lines.
- Use a local copy from stack for all updates, and then perform a global update that reflects these updates to the global entity.
False sharing problems can also be identified during the tuning stage using the VTune™ Performance Analyzer, and the appropriate measures can be taken in that stage to address this problem. In all cases, developers should avoid false sharing by carefully dividing the work among the threads to cache line boundaries.

Deployment problems?Welcome to microsoft open source solution WiX (or Windows Installer XML) toolset for creating MSI
What's in the box:
wix.xsd schema for MSI/MSM files
lit.exe library tool
tallow.exe code generation tool
you need to decompile your msi (generated from vdproj file) file via dark to .wxs
then you can generate binaries (.ibd) files by orca(from Microsoft Platform SDK) or by dark /x option
then compile it by candle to generate wixobj and link via light to get required MSI/MSM.
wix xml source file (.wxs) looks somthing like this...
<Product Id='000C1109-0000-0000-C000-000000000046' Name='TestAssemblyProduct' Language='1033' Version='0.0.0.0' Manufacturer='Microsoft Corporation'>
<Package Id='000C1109-0000-0000-C000-000000000046' Description='Test Assembly in a Product' Comments='Test from: wix\examples\test\assembly\product.wxs' InstallerVersion='200' Compressed='yes' />
<Media Id='1' Cabinet='product.cab' EmbedCab='yes' />
<Directory Id='TARGETDIR' Name='SourceDir'>
<Directory Id='ProgramFilesFolder' Name='PFiles'>
<Directory Id='TestAssemblyProductDirectory' Name='testassm' LongName='Test Assembly'>
<Component Id='TestAssemblyProductComponent' Guid='00030829-0000-0000-C000-000000000046'>
<File Id='TestAssemblyProductFile' Name='assembly.dll' essembly='.net' KeyPath='yes' DiskId='1' src='$(env.WIX)\examples\data\assembly.dll'/>
<Feature Id='TestAssemblyProductFeature' Title='Test "ssembly Product Feature' Level='1'>
<ComponentRef Id='TestAssemblyProductComponent' />
what more..you may integrate it with your NAnt scripts.
