Topic: [ANN] [SHA256]+[CPU] MediterraneanCoin (MED) - REUSE your ERUPTER!! - page 106. (Read 227779 times)

we are asking this in order to evaluate if it the case to modify some other miner (i.e. bfgminer) to work with the modified PoW algorithm.

Judging from you wrote and what I see on my screen (successfuly mining for hours now) you should be getting some blocks.

Unless CGMiner is working mcproxy does not do "Matrix" thing, it just idles. Does CGMiner shows any hashrate at all? I mean,
at 12 GHashes you should be getting 1 block every few minutes. At 38 GHashes it should jump to more than 1 block per minute.

ok thanx; instead of cgminer and outside of mediterraneancoin, what miner are you using with your cube?

I'll just quote myself from my earlier post. Basicly I think cgminer doesn't have drivers for these type of asics and you need a proxy. It seems the proxy works and when I login to the cube I see shares accepted (no rejects).

let's try to troubleshoot the problem:

can you post the output of:
- cgminer
- mcproxy

- is the wallet synced?

If anyone gets this running on their asic cube or blades please post. I gave up trying.

try Medit Coin - it's easier to remember

What about mcproxy? With everything setup properly, you need to run MED wallet then mcproxy and then CGMiner.

ok, you need to:

1 - start the wallet with -server option; you need also to define rpcuser and rpcpassword
example:

from msdos prompt, cd to windows-build directory and type:

mediterraneancoin-qt  -server -rpcuser=test rpcpassword=choose your password

2 - start mcproxy:
from the same windows-build directory type:
java -jar mcproxy.jar

3 - start the modified cgminer:

cgminer  -o http://localhost:8080 -u test -p

Thanks for the win build of cgminer

Now I have this problem: cgminer can't see my erupter..
In cgminer 3.1.1 I use this switch:
-S //./COM6
to let cgminer use my erupter..

I see this version have the icarus support, but how I can tel cgminer where is my erupter?

thanks !

Can anybody post here guide how to solo mine this coin on Windows with USB Erupter?
There is linux guide on the official site but I can not figure out how to make it work on Windows 7 64 bit.

Downloaded the wallet, installed Java, cgminer for medterranean, but can not start it properly... please help!!!

I like this coin's concept. But I think the name needs to be change to something else. It is too long to spell. Also it is restricted to Mediterranean. Also I suggest to make a pool instead of mining solo.

I got the wallet working, also the cgminer. But the server and solo mining thing just didn't work for me.

we have provided a win32 build of the modified cgminer, you can find it here:
http://www.mediterraneancoin.org/downloads/win32-cgminer-mediterraneancoin.zip


also, here is a complete tutorial for doing a win32 cgminer build on a fresh Ubuntu 12.04 64bit, following the instructions found here:

I was not so smart to compile the modified cgminer in windows: i follow this bible..
https://github.com/mrtexaznl/cgminer/blob/master/windows-build.txt
but now i cant execute "autoreconf" (and dunno why)

Can anyone successfully build it and can share?

thanks

I'm using 5 USB Erupters so hashrate is around 1.65 GHash

what is the hashrate reported by cgminer? A very high cpu usage by mcproxy could be caused by a high hashrate.

C:\Program Files (x86)\Java\jre7\bin>java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) Client VM (build 24.45-b08, mixed mode, sharing)

It is 32-bit version.

what version of Java JRE are you using? can you report the output of the following command:
java -version

Peaking at 50% and mostly around 35%, going as low as 0% occassionaly. CPU is Intel Core 2 Duo P8600 (2.40GHz)
on Lenovo T500 notebook. RAM usage is around 40MB, no wild swings. Machine runs Win7 64-bit and has 4GB RAM.

In the last hours it has happened also to us to have a few mined blocks refused by the network; this is part of the rules of bitcoin/litecoin protocols, however, it should not depend on the new proof of work algorithm.

When a block with a good PoW is found, it is immediately sent to the network for acceptance; it is the network which reaches a majority and eventually accepts the transaction.
If can happen that a new mining transaction is refused because somebody else has found another solution to the same block, just a fraction of second before.

Regarding the fact of finding two blocks in a few minutes, that is luck!

Regarding the stability of mcproxy, can you report the CPU usage for the java process?
