Hello,

More of my philosophy about the how many memory channels in the 16 sockets HPE NONSTOP X SYSTEMS and more of my thoughts..

I am a white arab, and i think i am smart since i have also
invented many scalable algorithms and algorithms..

I think i was right by saying that the 16 sockets HPE NONSTOP X SYSTEMS or the 16 sockets HPE Integrity Superdome X have around 2 to 4 memory channels per socket on x86 with Intel Xeons, and it means that they have 32 or 64 memory channels.

You can read here the FAQ from Hewlett Packard Enterprise from USA so that to notice it:

https://bugzilla.redhat.com/show_bug.cgi?id=1346327

And it says the following:

"How many memory channels per socket for specific CPU?

Each of the 8 blades has 2 CPU sockets.
Each CPU socket has 2 memory channels each connecting to 2 memory controllers that contain 6 Dimms each."

So i think that it can also support 4 memory channels per CPU socket with Intel Xeons.

More of my philosophy about the highest availability with HPE NONSTOP X SYSTEMS from Hewlett Packard Enterprise from USA and more of my thoughts..

I have just talked, read it below, about the 16 sockets HPE Integrity Superdome X from Hewlett Packard Enterprise from USA, but so that
to be the highest "availability" on x86 architecture, i advice you to buy the
16 sockets HPE NONSTOP X SYSTEMS from Hewlett Packard Enterprise from USA, and read about it here:

And here is more of my thoughts about the history of HP NonStop on x86:

More of my philosophy about HP and about the Tandem team and more of my thoughts..

I invite you to read the following interesting article so that
to notice how HP was smart by also acquiring Tandem Computers, Inc.
with there "NonStop" systems and by learning from the Tandem team
that has also Extended HP NonStop to x86 Server Platform, you can read about it in my below writing and you can read about Tandem Computers here: https://en.wikipedia.org/wiki/Tandem_Computers , so notice that Tandem Computers, Inc. was the dominant manufacturer of fault-tolerant computer systems for ATM networks, banks, stock exchanges, telephone switching centers, and other similar commercial transaction processing applications requiring maximum uptime and zero data loss:

More of my philosophy about HP "NonStop" to x86 Server Platform fault-tolerant computer systems and more..

Now HP to Extend HP NonStop to x86 Server Platform

HP announced in 2013 plans to extend its mission-critical HP NonStop technology to x86 server architecture, providing the 24/7 availability required in an always-on, globally connected world, and increasing customer choice.

Read the following to notice it:

https://www8.hp.com/us/en/hp-news/press-release.html?id=1519347#.YHSXT-hKiM8

And today HP provides HP NonStop to x86 Server Platform, and here is
an example, read here:

https://www.hpe.com/ca/en/pdfViewer.html?docId=4aa5-7443&parentPage=/ca/en/products/servers/mission-critical-servers/integrity-nonstop-systems&resourceTitle=HPE+NonStop+X+NS7+%E2%80%93+Redefining+continuous+availability+and+scalability+for+x86+data+sheet

So i think programming the HP NonStop for x86 is now compatible with x86 programming.

More of my philosophy about the 16 sockets HPE Integrity Superdome X from Hewlett Packard Enterprise from USA and more of my thoughts..

I think i am highly smart since I have passed two certified IQ tests and i have scored "above" 115 IQ, so i think that parallel programming with memory on Intel's CXL will be different than parallel programming the many memory channels and on many sockets, so i think so that to scale much more the memory channels on many sockets and be compatible, i advice you to for example buy the 16 sockets HPE Integrity Superdome X from Hewlett Packard Enterprise from USA here:

https://cdn.cnetcontent.com/3b/dc/3bdcd896-f2b4-48e4-bbf6-a75234db25da.pdf

And i am sure that my below Powerful Open source software project of Parallel C++ Conjugate Gradient Linear System Solver Library that scales very well will work correctly on the 16 sockets HPE Superdome X.

More of my philosophy about the future of system memory and more of thoughts..

Here is the future of system memory of how to scale like with many more memory channels:

THE FUTURE OF SYSTEM MEMORY IS MOSTLY CXL

Read more here:

https://www.nextplatform.com/2022/07/05/the-future-of-system-memory-is-mostly-cxl/

So i think the way to parallel programming in the standard Intel’s CXL will look like parallel programming with many memory channels as i am
doing it below with my Powerful Open source software project of Parallel C++ Conjugate Gradient Linear System Solver Library that scales very well.

More of my philosophy about x86 CPUs and about cache prefetching and more of my thoughts..

I think i am highly smart since I have passed two certified IQ tests and i have scored "above" 115 IQ, and today i will talk about the how to prefetch data into the caches on x86 microprocessors:

So here my following delphi and freepascal x86 inline assembler procedures that prefetch data into the caches:

So for 32 bit Delphi and Freepascal compilers, here is how to prefetch data into the level 1 cache and notice that, in delphi and freepascal compilers, when we pass the first parameter of the procedure with a register convention, it will be passed on CPU register eax of the x86 microprocessor:

procedure Prefetch(p : pointer); register;
asm
prefetchT1 byte ptr [eax]
end;

For 64 bit Delphi and Freepascal compilers, here is how to prefetch data into the level 1 cache and notice that, in delphi and freepascal compilers, when we pass the first parameter of the procedure with a register convention, it will be passed on CPU register rcx of the x86 microprocessor:

procedure Prefetch(p : pointer); register;
asm
prefetchT1 byte ptr [rcx]
end;

And you can request a loading of 256 bytes in advance into the caches, and it can be efficient, by doing this:

So for 32 bit Delphi and Freepascal compilers you do this:

procedure Prefetch(p : pointer); register;
asm
prefetchT1 byte ptr [eax]+256
end;

So for 64 bit Delphi and Freepascal compilers you do this:

procedure Prefetch(p : pointer); register;
asm
prefetchT1 byte ptr [rcx]+256
end;

So you can also prefetch into level 0 and level 2 caches with the x86 assembler instruction prefetchT0 and prefetchT2, so just replace, in the above inline assembler procedures, prefetchT1 with prefetchT0 or prefetchT2, but i think i am highly smart and i say that notice that those prefetch x86 assembler instructions are used since also the microprocessor can be faster than memory, so then you have to understand that today, the story is much nicer, since the powerful x86 processor cores can all sustain many memory requests, and we call this process: "memory-level parallelism", and today x86 AMD or Intel processor cores could support more than 10 independent memory requests at a time, so for example Graviton 3 ARM CPU appears to sustain about 19 simultaneous memory loads per core against about 25 for the Intel processor, so then i think i can also say that this memory-level parallelism looks like using latency hiding so that to speed the things more so that the CPU doesn't wait too much for memory.

And now i invite you to read more of my thoughts about stack memory allocations and about preemptive and non-preemptive timesharing in the following web link:

https://groups.google.com/g/alt.culture.morocco/c/JuC4jar661w

And more of my philosophy about Stacktrace and more of my thoughts..

I think i am highly smart, and i say that there is advantages and disadvantages to portability in software programming , for example you can make your application run just in Windows operating system and it can be much more business friendly than making it run in multiple operating systems, since in business you have for example to develop and sell your application faster or much faster than the competition, so then we can not say that the tendency of C++ to requiring portability is a good thing.

Other than that i have just looked at Delphi and Freepascal and
i have just noticed that the Stacktrace in Freepascal is much more enhanced than Delphi, since look for example at the following application of Freepascal that has made Stacktrace portable to different operating systems and CPU architectures , and it is a much more enhanced stacktrace that is better than the Delphi ones that run just in Windows:

https://github.com/r3code/lazarus-exception-logger

But notice carefully that the Delphi ones run just in Windows:

https://docwiki.embarcadero.com/Libraries/Sydney/en/System.SysUtils.Exception.StackTrace

So i think that since a much more enhanced Stacktrace is important,
so i think that Delphi needs to provide us with a portable one to different operating systems and CPU architectures.

Also the Free Pascal Developer team is pleased to finally announce the addition of a long awaited feature, though to be precise it's two different, but very much related features: Function References and Anonymous Functions. These two features can be used independantly of each other, but their greatest power they unfold when used together.
