#8974 — .NET and Processor Groups

Someone in my killfile posed some incorrect information about .NET and
processor groups on large Windows systems.  I saw that post as part of
someone else's reply.

Namely, it *is* possible for a .NET application (at least since v4.5
or so), to schedule threads on multiple processor groups, and thus not
be limited to the maximum of 64 threads that be in a single processor
group.

It is a feature that needs to be enabled.  Details at:

I have tested it under Mono and it is not supported under Mono.



Thank you,

Hello,

Sorry , it is working with Mono, here is the configuration file that i 
am using:



<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <runtime>
       <Thread_UseAllCpuGroups enabled="true"/>
       <GCCpuGroup enabled="true"/>
       <gcServer enabled="true"/>
    </runtime>
</configuration>




Thank you,
Amine Moulay Ramdane.
