Which GPU's did you settle on?

Right now

2x GTX 1050 Ti (already installed)
and
1x GTX 1080 Ti (ordered, will receive next week)

But I will buy more a little later, when prices come down a little.

Sweet - I use all 1070's.  Let me know how that 1080ti works.  I am looking to purchase some more rigs.  Might consider the 1080's.

So how many hashes does a 1070 do with the normal miner?
And how much better does it get with sp_'s improved miner?

I will keep you updated about the 1080 Ti

Unfortunately, I only have SP's miner as a tool.  It gets 8500 - 8900 mhs/sec.  I have the mem clock down to -512 and the core clock at +125.

@Gerogem - what do the 1050ti's get on Spreadx11?

Each a little over 2500 khs.
But that's with the old spreadminer (tsiv).
And I am not doing any overclocking.

I went with those 2 first, because TDP is just about 70 Watts, and they are very silent. (and they cost only about 140$)

I think with SP miner they should average about 3000 khs

I believe I am running (2) nodes - one on my windows machine (wallet & daemon) and one on the Rpi3 - Is that possible on the same IP?  Although I use a VPN on the Windows machine - so it is (2) separate IP's.  LOL - I think I just answered my own question.

That is a very interesting and far-reaching question.

It depends how you want your full node to appear to the outside world (so that other nodes can find it).

To first answer your question. YES, you can have as many nodes (of the same coin) as you like behind the same external IP, but NOT behind the same IP and Port!

Meaning, if you set your router to forward port 41678 to a specific computer in your local network, then that computer is the only node that will be accessible through this IP/Port combination.
Any other local nodes will have to use another port and will only be able to make outbound connections to the network, they will not easily accept inbound connections. (which is actually good from a security standpoint)

This is the whole secret behind why some full nodes max out at 8 connections,
but other nodes (on a server for example) can have 100 or more connections.
The latter is more visible to the outside world and is broadcasting in the IP/(official Port) combination for other nodes to use.

In that sense, this is all very interesting, because it ties a little to this general theme that we keep hearing about with bitcoin,
you know... that bitcoin has 5-6000 full nodes?
Yes, but those are all full nodes that run on the official port and are therefor easily accessible by other nodes and will readily accept both outbound and inbound connections.
But there are actually probably 20-30000 additional full bitcoin nodes that run in the same mode that your secondary rasp pi is running,
such "secondary full nodes" are able to connect to the network and share blockchain data, but they do not allow inbound connections just like that.

You can do the following experiment:

Set up your router to forward port 41678 to a certain node in your local network, and then observe what happens to the max connections with this node and the other "secondary" nodes (that don't use the official SPR port).

Fun stuff, I like your questions a lot pokey, you are thinking! 8)

BTW - I did this and now I enjoy 38 connections to my new Rpi3 node!  I still can't get my wallet on another computer to show more then 8 connections.  I do have it on a different port but I forwarded that port number and also opened it up in Windows Firewall for both private and public.  Oh well.  It still works nicely.

Ok, I will further explore this, and try to recreate your situation. This could have many different reasons.
I'm also looking into connectivity when a node is in IPv6 or TOR mode.
Will keep you guys updated.

@Georgem - I just realized you have a slack channel.  LOL - I am pretty sure I have donated over $100.  Can I get an invite pretty please?  ::)

Sure, please send me your email address through PM.

PS: Although I try to limit slack to people who pay over 100$ a month, but I will make an exception for you, since you have been so cooperative all this time.
BTW, the amount is just arbitrary, I put it this high, because actually I do not really have time for slack, lol. But we can chat a little, sure!  8)

Wellwell, a few packages for the raspberry pi cluster have arrived:



This is the casing that I am using.
It will hold 48 Raspberry Pi's, all their Powersupplies and a 48 port switch.

... lots and lots of spacers and screws that I will use to mount the raspberry pi's on plexiglas plates.
(3x raspberry pi's per plate)



...more packages with interesting stuff should arrive soon.

I am liking where this is going!  A super node?

The raspberry cluster will allow me to basically have a...

"testnet in a box"

As if creating P2P software isn't hard enough, what's making it even more difficult for devs is that P2P applications only show their true (often unexpected) behaviour when they are running on the network.
So then, how can you quickly debug, develop and test P2P software when you only have 2 or 3 computers to test on?

Well, you can't really, and that's where the "testnet in a box" comes in.

48 nodes is a pretty decent network.

I'll explain more as the "process of creation unfolds" ...  ;)

So think of it this way:

1) The cluster is my own local network where I develop and test the next version/iteration of spreadcoin/servicenodes.

2) Once I am confident that the next version behaves as expected I will release that version for the actual testnet (you guys!)

3) If this works out well too, we can switch the version to mainnet.

Voila.
