Supercomputers will not reach that memory 16 Exabyte capacity in the nearer future, but since they don't have a shared memory space then 128-bit won't be that important.



I know a bunch of navy people who would be willing to classify the Zumwalt-class destroyer as a Battleship. The consensus seems to be that it's called a Destroyer only because BB's are presently the butt of the joke about following the old paradigm too long, when everyone should have been building aircraft carriers instead.

It's only 15k tons, which is a far cry from the Iowa class Battleship, but it's still heavier than many of the Pre-DN battleships. It's certainly not a destroyer, because DD's are traditionally used for killing small ships, submarines and aircraft, each of them a task that the Zumwalt does not do. Instead, Zumwalt is meant for engaging surface and ground targets with missiles and guns. It only has 2 guns, but they are water-cooled, fully automated and have fire rates good enough that it can land as many projectiles per minute on the target as the Iowa. The projectiles themselves are, of course, much lighter and guided.




Today's 64-bit Intel CPUs can only address 48-bit memory btw, cost savings because nobody will have that much memory in one machine for the foreseeable future. more $$ for intel and AMD.




In a sense it's both 48-bit and 64-bit at the same time. The actual addresses are 64-bit, but the specification of AMD64 only allows the first 48 bits to be used; bits 48-63 are just a copy of bit 47.



If the memory controller was implemented as 64 bit instead of 48 bit, there would be no performance difference. but using 48 bit math instead of 64-bit, saves you transistors.



The Ext4 file system physically limits the file block count to 48 bits.



The minimal implementation of the x86-64 architecture provides 48-bit addressing encoded into 64 bits; future versions of the architecture can expand this without breaking properly written applications.


The media access control address (MAC address) of a computer uses a 48-bit address space. This can be changed to 64-bit addressing.



A 48-bit memory address can directly address 256 Terabytes. A processor with 64-bit memory addresses can directly access 16 Exabytes.



In principle, a 64-bit microprocessor can address 16 Exabytes of memory. However, not all instruction sets, and not all processors implementing those instruction sets, support a full 64-bit virtual or physical address space.


The x86-64 architecture (as of 2016) allows 48 bits for virtual memory and, for any given processor, up to 52 bits for physical memory. These limits allow memory sizes of 256 Terabytes. A PC cannot currently contain 256 Terabytes of memory (due to the physical size of the memory chips), but AMD envisioned large servers, shared memory clusters, and other uses of physical address space that might approach this in the foreseeable future. Thus the 52-bit physical address provides ample room for expansion while not incurring the cost of implementing full 64-bit physical addresses.



The free software used to implement RISC-V architecture is defined for 32, 64 and 128 bits of integer data width.

ZFS is a 128-bit file system.

https://en.wikipedia.org/wiki/ZFS

https://github.com/zfsonlinux/zfs


One important feature of making a 128 Bit ASIC with high amounts of RAM, is that 1. We can break out the limits of Memory that way using Yitang Zhang algo.  2. 64 bit and 32 bit virus programs cannot be run on 128 bit ASIC machines.

I learned that git submodule update needs to be git submodule update --remote --merge
But, reading more extensively, I realised what I'd been missing. Previously, when looking at the status of the changes, I thought that git was offering me the option of including all of PoWCore in the main Gapcoin repos ... well, I mean, who wouldn't? ...
Code:
On branch v0.9.3-gap
Your branch is up-to-date with 'origin/v0.9.3-gap'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)
  (commit or discard the untracked or modified content in submodules)

modified:   src/PoWCore (new commits, untracked content)

no changes added to commit (use "git add" and/or "git commit -a")

But when I looked at the actual difference, it was offering to update the reference from:
Code:
ID       : ca5e863b1ff6c0a9655fadb951f1d9653ba24ef1

Author   : Jonny Frey <j0nn9.fr39@gmail.com>

Message:

Author   : Graham Higgins <gjhiggins@users.noreply.github.com>
           26/10/2019 11:04

Committer: GitHub <noreply@github.com>
           26/10/2019 11:04

Message:
Update PoWUtils.h

Address compilation failure

which is actually what I wanted.

So I committed the change and the submodule update now works correctly as before, i.e. git submodule update and doesn't need the --remote --merge any longer.

We can all breathe a sigh of relief Smiley

Cheers,

Graham




Mint uses Boost 1.65 would it still compile on Linux with Boost 1.67?
I have successfully compiled the gapcoin v0.9.3-gap branch on an Ubuntu 19.10 system.

I checked the compilation under Ubuntu 16.04 (the earliest version of Ubuntu still supported) and added (and documented, in doc/build-unix.md) a couple of patches to allow gapcoin-0.9.2 (the “official” distro) to compile under Ubuntu 16.04.

In gapcoin-0.9.3, I've changed rpcserver.cpp in order to get to compile successfully under Boost 1.67 (and Boost 1.65) and have committed the change (to https://github.com/gjhiggins/gapcoin.git).

I haven't yet committed the gapcoin-0.9.4 branch that I'm working on.

Cheers

Graham




I'm pretty much done with setting up the support infrastructure for the mersenne forum prime search group's pick-up of the maintenance and publishing of Dr Tom Nicely's list of first known occurrence prime gaps.

Github org- https://github.com/primegap-list-project

List is here https://github.com/primegap-list-project/prime-gap-list and maintained as statements in SLQLite3 SQL, can be simply d/l and read into SQLIteBrowser.

Org website: https://primegap-list-project.github.io

Gapcoin contribs are summarised here: https://primegap-list-project.github.io/lists/ (see top discoverers) and graphed here https://primegap-list-project.github.io/graphs/ - (the website is a Github pages static website, dynamics courtesy of in-browser javascript - and it renders on my smart TV, lol).

I committed all 451 new merits discovered by the Gapcoin network up to early Nov (there's another 9 to add from since then): https://github.com/primegap-list-project/prime-gap-list/commit/ea672fa28f499846b566adc1ea2be33fdbe4855c

Thanks for all your efforts, input and hard work on this one Graham (and community !?!) ...

A belated Happy New Year !

I have to migrate some of the servers to new LTS builds and I will be updating the https://gapcoin.club website with new info.

Anyone for a new windows release with updated SSL etc., ?

Getting very bored of 'slow play time', lets build this community and start to get listed on some additional exchanges etc.,

Again, Gapcoin is going nowhere, except for the record books !

No such thing as an economic point of no return.

 Wink

P.S. I'm continuing to renew the block explorer, again.

Cheers!



We're searching for some very special numbers ... anyone care to join us !?

Wat do I do after that?

Counting down to your launch though!

If you compiled everything successfully, that's it for now.
Just wait for the launch.&nbsp; Wink

Also: &quot;The source code will not contain the neccesary Proof of Work functionality, its only to set up and test compile environment.&quot;

-You gonna push this on launch? Or just binaries?


Yes, the entire source code will be published at launch.



Have you contacted pool operators/worked with pool code so that this is a possibility at launch?

Have you worked with GPU miner devs to develop a GPU algo for your PoW code?


This is in progress, but probably we won't have a pool right at the start.

Also Gapcoin is currently CPU only.
Is TVT a shitcoin right now ? I mean, it will be the clash of the titans between TVT, Flappycoin, Dojecoin and Tittiecoin ? 1TVT = 1 tittoshi in aprox 2 months ?guys can anyone confirm that TVT does not use a mixer to create anon transactions. if so, then TVT is the best anon out there

@BitcoinFX Nobody cares what you are up to. The coin and its honeycombed structure of interlaced networks is marching ahead at a steady pace which will accelerate to gallop before Chinese new year. Times are changing, you are either with us or behind us. The stink is hovering in the air while the air is hovering in the space as an illustration of the universal law of embedment which also gives some philosophical pretext to the possibility of the perpetual machines of the first kind.

What is TVT? GAP has no ties to it.

Thanks for that one! What is this even supposed to mean?

Would you prefer that I switch off my Gapcoin nodes (including Tor nodes) + the gapcoin.club website, that I cease paying for the only block explorer and stop trying to get Gapcoin listed on new crypto exchanges etc., ...

... or perhaps are you just trolling this thread for arguably the most brilliant math coin to grace bitcointalk ... where the developers seemingly passed away in tragic circumstances.

Images from printed primes

Inspired by James McKee's Numberphile video and subsequent "Futility closet" post on the "Trinity Hall prime", physics researcher Gilles Esposito-Farèse discovered a prime number that, when printed, forms this image.



(more images on Gilles' page (ref above).

Elsewhere, it has been discovered that primes conspire amongst themselves: https://www.quantamagazine.org/mathematicians-discover-prime-conspiracy-20160313/

Happy New (Gregorian) Year.

Nope. Gapcoin is most certainly very much alive. However, the OP most likely has very sadly passed away.

Gapcoin is an important Math based cryptocurency that actually broke and seemingly still holds the world record prime gap.

Prime gap's ...
- https://en.wikipedia.org/wiki/Prime_gap

"As of December 2017, the largest known merit value and first with merit over 40, as discovered by the Gapcoin network, is 41.93878373 with the 87-digit prime 2937032340680225901587237661044194634257090755748117620985887982178957288586767 28143227. The prime gap between it and the next prime is 8350."

We can break new records using Gapcoins existing proof-of-work. You can mine Gapcoin with your computers CPU in-wallet currently, just like you could with Bitcoin circa <2009-2010+ (for it to be worthwhile) ...

The Gapcoin project is maintained here: https://gapcoin.club

With growing community interest a new thread [ANN] is very likely indeed. Gapcoin is a genuinely amazing cryptocurrency project and has been ignored under the radar for to long.

...

P.S. Chatter is not off-topic and concerns Prime numbers / historical computing, as does Gapcoin.
