What is NUMA (Non-Uniformed Memory Access)

Non-Uniform Memory Access (NUMA) is one of the computer memory design methods used in multiprocessor systems, and the time to access the memory varies depending on the relative position between the memory and the processor. In the NUMA architecture, when a processor accesses its local memory, it is faster than when it accesses the remote memory. Remote memory refers to memory that is connected to another processor, and local memory refers to memory that is connected to its own processor. In other words, it is a technology to increase memory access efficiency while using multiple processors on one motherboard. When a specific processor runs out of memory, it monopolizes the bus by itself, so other processors have to play. , and designate 'access only here', and call it a NUMA node.

1. Check Nodes

lspci | grep -i nvidia
  
01:00.0 VGA compatible controller: NVIDIA Corporation TU106 [GeForce RTX 2060 12GB] (rev a1)

Run regedit.exe elevated.
Take ownership of HKEY_CLASSES_ROOT\AppID{CDCBCFCA-3CDC-436f-A4E2-0E02075250C2}.
Rename the RunAs value to _RunAs.
Create a new shortcut on your Desktop for C:\Windows\System32\runas.exe.
Name it something like Admin-Explorer.
Right-click the new shortcut and click Properties.
Change the target to: C:\Windows\System32\runas.exe /noprofile /user:<domain>\<username> "c:\windows\explorer.exe /separate"
(Optional) Change the icon.
(Optional) Pin to taskbar.

101 Rx Samples in C#

This was taken from http://rxwiki.wikidot.com/101samples, because I wanted to be able to read it more comfortable with syntax highlighting.

Here's the unedited original, translated to Github Markdown glory:

101 Rx Samples - a work in progress

	Windows Registry Editor Version 5.00

	;The registry setting shown below requires Trusted Installer privileges to change.

	;If the "RunAs" value is deleted or renamed or the "Interactive User" data is changed to something else,
	;such as an empty string, you will then be able to right-click Explorer and "Run as Administrator".
	;Of course, you can then create a shortcut to Explorer that has "Run as Administrator" checked.

	;Disabling this restriction may have consequences. One concern regards what happens if you are at a
	;"Run as Administrator" or "Run as Trusted Installer" Cmd prompt and then kill all Explorer processes
