According to MSDN documentation and Stephen Toub answer, my C# app should use every Logical Processor of every Processor Group because it is configured as required (see my App.config below).
I run my app on a windows server 2012 with a NUMA architecture: 2 x [cpu Xeon E5-2697 v3 at 14 cores each with Hyper Thread activated] => 2 x 14 x 2 = 56 Logical Processors.
My app start 80 threads either from "Thread Class" or "Parallel.For" and in both case it only takes 28 Logical Processors, all from the same Processor Group.
Why does the Task scheduler assign my threads on only one Processor Group?
My code is available at GitHub or the executable could be downloaded at my Home website
I've already asked this question on social.msdn.microsoft.com without any answers.
Update 2015-01-26: I reported a bug at connect.microsoft.com
Update 2015-01-30: I added CoreInfo dump as additional references.
Update 2015-01-30: The problem occurs also with prime95 where it only offer to select 28 threads (not c# related)
Update 2015-01-30: My tool now show more information like Processor Mask per node. It sounds like I do not have access to the other node (the node I do not run in)
Update 2015-02-02, We do NOT have Citrix installed on this particular server (sorry, I was wrong)
Update 2015-02-02, We contacted HP...
Update 2015-02-03, Added more information to my program to display processorGroup per thread and few more little gadgets.
Update 2015-02-17, After talked to HP dev team, I updated my answer to reflect what I learned. (Just want to mention that I received EXCELLENT support from HP)
Update 2015-05-13, HP confirmed the problem in a "Customer Advisory" note. See this linked document id: c04650594
I set my .Net 4.5 (or 4.5.1) App.Config to:
<?xml version="1.0" encoding="utf-8"?>

Note: I thought we fixed the problem by changing "Interleaved Memory" parameter in the bios. But i gives us weird results. According to Microsoft Technet we set back the BIOS setting to "NON-Interleaved memory"** (which is required by the OS to see the system as NUMA).
476
The bug has been fixed by a new (yet unpublished) HP Bios (at the time of writing this).
The new Bios (targeting HP Proliant DL360 and DL380 Gen9) introduce a new setting: "NUMA Group Size Optimization" with choice of [Clustered - default] or [Flat]. HP says to set it to flat.
The sceenshot part of this answer has been conducted on a DL380 instead of a DL360 because of server availability. But I expect same behavior on DL360. The problem disapeared, we had only one group.
As far as I know, the OS communicate with the BIOS to know the CPU(s) configuration. The Bios play an important role in how the OS will present the logical processors available to applications (Processor Group, Affinity, etc).
About the Microsoft documentation Supporting Systems That Have More Than 64 Processors and Processor Groups it is clearly stated that more than one processor group will only be created when the Logical Processor (LC) count is >64. On our server (56 LC) with Numa Architecture set to "Clustered" we had 2 processor groups. A hardware engineer working at HP Bios dev team explained me that when set to "Clustered", the Bios is fooling Windows by padding the real number of logical processor to 72 Logical Processor (the max number of Logical Processor for the E5 v3 Family). The real number of LC is 56 in our DL360. That's the reason why we add 2 groups instead of 1. The Microsoft documentation seems accurate. I personally think that it would be better to create 1 group per numa node whenever possible but in our case, there is a bug. What is faulty is hard to know between HP or Microsoft when the HP Bios setting is set to Clustered (default) but Microsoft seems to not support that option which seems to cause our problem.
On HP Bios for DL360 and DL380, The Bios configuration "Numa Configuration" set to "Clustered" (default) will create 2 groups although there is only 56 Logical Processors (when hyperthreaded). The result is that only one processor is visible at a time for any application. Probably also due to HP fooling Windows by padding fake number of Logical Processors. It sounds like Microsoft does not expect that. Our C# app can't run on the 2 groups. It's hard to blame Microsoft on that behavior where HP does something they can't anticipated. Perhaps we will see, one day, Windows supporting many groups when LC <= 64.
About Prime95. This CPU stress test software has good documentation on Wikipedia that clearly state that it will load into only one processor group (in Limits section).

Try setting your code to build "optimize code" and the target platform to "x64". (it worked for me with your code, on a server with 80 cores)
