I'm willing to help in some ways that I can with this community of magi

Thanks you! Welcome to the Magi community.

[M7M hardfork in testnet]

Here we are going a hardfork to be happening on 10/17/2014 8:00 PM EST [only testnet at this time]. This update enhances the CPU mining. We will be living with the new algo from now on. In my view, this new M7M will pretty make it very hard to implement GPU miners. A major change is the addition of a sequential algorithm with iterative numerical computation using GMP floating-point numbers. I will expect this disables any on-going efforts of parallel implementation. GMP floating-point numbers allow "infinite" accuracy while we have to compromise to a certain level to avoid largely depressing hash rate. Surely I've taken the chance to further "mess up" the things that makes CPU hashing quite straightforward, while GPU mining even hard and impossible. Our block-rewarding system will give great chance for CPU mining too. As a consequence of the algo changing and hashing hard, the hash rate has to be compromised somewhere. The hashrate of my AMD 8350 is reduced from 79.2 kh/s (built-in mining) to 28.5 kh/s, and my VPS is reduced from 22.5 kh/s to 9.1 kh/s.

Why CPU mining?

Because ... people like it! I received feedback that some people just happy with VPS mining XMG. Well this is not big deal regarding the mining earnings, but what if you use your VPS to mine bitcoin or litecoin? The most advantage of XMG is that you can always mine a few coins if you want and this can remain forever; will the same rule apply for other CPU coins? I don't think so; the conventional CPU coins have the growth pain because of the joining of big CPU mining farms. For XMG, we pretty make use of the new block rewarding system that avoids the coming of huge network hashrate.

So CPU mining is guaranteed?

I won't say this is 100% CPU coin, but will say 100% CPU minable. Check out relevant information, figure yourself.
https://github.com/magi-project/magi/blob/master/src/hash_magi.h

Are we safe?

Though the network hashrate has been pretty much limited, Magi is pretty secure, because of the hybrid PoW/PoS-II system. I will come back to the PoS-II part.

Instructions:

As aways, be sure to back up wallet.dat

Download binary wallets from here:
http://cryptomagic.com/files/magi-release/m7m-hardfork-testnet-v1.0.0.3/

Or compilation from github source:
https://github.com/magi-project/magi

The testnet wallet can be running with the mainnet wallet simultaneously.

Quote
1) Example: launch you mainnet wallet first
2) Change magi.conf by setting testnet=1 and rpcport=18232
3) Run the qt wallet again, you will be on the testnet

Run daemon in tesetnet from the command line:

Code:
magid -testnet -rpcport=18232
Check info:
Code:
magid -testnet -rpcport=18232 getmininginfo

Please take time to test it out and report hashrate before and after the hardfork, that will help us to refine the block-rewarding system once with the new algo. I will fire up the standalone miners soon later. I've already tested the hardfork in my side, so don't see any issues with that. After testnet, we will plug hard fork into the main net.

Planned hard fork in the main net: 10/24/2014 3:00 PM EST

If you're not intent to test the testnet hard fork, you won't need to do anything, also unnecessary to use the new wallet for the main net.

A small company around here contacted me to explain them this crypto thing. I am supposed to give them a rough estimation of what they can produce with the few xeons they cannot manage to load (I think we're talking about 64 cores at most, for a few hours day).

Where can I find performance data?
I've seen some coins using google docs for this and I've been positively impressed with the usability.

As a side note, the proposed fork is a nice coincidence. I can tell for sure this will give me quite some troubles.

So the machines I leave running mining unattended over the weekend will be useless for two days after the hardfork?

No if i read it right, Joelao95 wants to test this first.
So you can mine as usual!

Just to confirm that fork is happening in about 2.5 Hours?
Also would be good that pools confirms when they switch.

The hashrate of my AMD 8350 is reduced from 79.2 kh/s (built-in mining) to 28.5 kh/s, and my VPS is reduced from 22.5 kh/s to 9.1 kh/s.


(woohoo the 2 points gaussian fit is back  Grin... this is so wrong mathematically physically... but I guess you don't care...)

At which block your hardfork ? (because at 8:00pm isn't a block number... ) and unless you want 2 forks you should say at which block it starts.... the funny thing is if some of the big whale don't change their wallet you are screwed, considering that the new wallet divide by 2~3 the hashrate... (if they keep the old one, they will have a clear advantage over the new fork... and could even take over  Grin)

So you should really do a proper announcement with enough time before the hard fork so everybody can move to the new wallet.
not like your "hardfork in 5minutes"... as you did here...



Actually my problem with this coin (and I am pretty sure others feel the same) is that there is too much dev (divine) intervention and control.
But here everything here change change too much too often (since we should expect a second fork after the fork ( Grin) to adjust the reward system. (and when we see how things are announced... with not enough time to prepare for a fork... I am a bit worried about the future of the coin... )

Last point: What happens to the coin swap ?
Because the net hashrate gets divided by 2~3, the rate 1:4 is getting insanely high (compared to what you could get through mining).
And this point hasn't been debated at all.

The scarcity of the coin increases (again) while the magi holder keep their 1:4 swapping ratio  Huh
It feels like xmg miner are getting really screwed over this one...

Just a brief comment.
I understand your comment.
The problem in this case is that the developer has been active until late tonight.
Maybe he did not view well in time.
The swap is precisely controlled so that the miners are protected.
In addition there is a donation for a possible second POM campaign.
Read these links, then you'll be informed.

Seems like quite a few people aren't noticing the TESTNET part of the announcement...

Noticed it but If I understand correctly:
the test through testnet is happening now
the fork at  10/17/2014 8:00 PM EST (ie sometimes this evening European time).

And quite frankly a fork is serious business, the message should be clear enough so that there is no place to interpretation. (here we have at least 2 persons who didn't understand the message in the same way... )

Usually most of the coin fork after an announcement with a week in advance... (with a block number high enough so everybody has enough time to move to the new wallet...). Here well we don't even know the block number...
The exchange will face the same problem, they won't have enough time to move to a new wallet either...

I know a coin which did fork without prior announcement: BBL, ended with 2 blockchain (1 for poloniex and another one for bittrex...  and died...)

yes, the 1:16 ratio is a bit better, hope it will stop the exchange rate getting divided by 2 every weekend...

What is all the fuss about? I think Joe made it clear enough that the hard fork is happening on the testnet. I thought that I had bad eyesight, but didn't miss that bit of info. Happy to report that I had the test wallet up and running in no time. Looking forward to seeing the new algo in action. I get 20~21 Kh/s  from the wallet on my AMD FX4100 (exactly half that possible with the current 64 bit standalone minerd.exe).

with hardfork tonight on main network... which isn't enough time...  (I don't know if you have bad eyesight, but may-be concentration problem if your can't read the whole sentence  Grin ... luckily for me you won't see that message either... that's why I started my message with the 3 words you didn't read in Joelao95 post...)
