Scratch that.

It seems to have come back around and seems a bit more normal the last few minutes.

I just notice my bitcoinr log file showed the server was down for a few minutes, and now it shows the additional line:

0 blocks generated since 2010-12-05 12:16:18 UTC

Thanks for the extra info.

However, I've noticed my bitcoinr log also says "Server reports my khash/s as 566" very consistently.
This use to say "Server reports my khash/s as 833" very consistently.
I'm seeing the same behavior accross my 3 boxes I have running bitcoinr.

I'm curious as to what changed on the server side, cause I didn't change a thing on my end and it seems to report less khash/s now than it did before the change.

The server stopped for some reason. I've restarted it.

The khash rate seems to be oscillating for me. It reports 400 khash/s then the next report it's 1600. The average of those 2 is 1,000 which is the normal rate for my cpu. Odd. The total combined khash rate is also oscillating. I think the server is overloaded. It's pegged at a 100% CPU right now with 143 clients.

Hi,

I get a compilation error when building under Ubuntu Lucid in an x86_64 arch. I just got the latest version from github, and the only modification I made was adding the following code to the end of cmake-bitcoinr/CMakeLists.txt as described previously in this thread.

Code:

IF(NOT WIN32)
TARGET_LINK_LIBRARIES(bitcoinr pthread)
ENDIF(NOT WIN32)

Anyway, though the invocation of 'cmake .' succeeds:

For those not following the other thread, the pool generated its first block today:

I suggest server operators let everyone know the time they will be updating, and everyone else make their best effort to update their clients at that time.

I will most likely be doing this after the weekend sometime. I'll post a more exact date/time later.

I've been requested to set up a git repository with changes specific to getting the remote miner compiled on linux. I've done this and it's at: https://github.com/doublec/bitcoin-pool

The 'master' branch should build the remote miner only on linux by running cmake followed by make. The 'bitcoin-remote-20101201' branch contains the source originally from puddinpop for that version with no changes. You can get a diff to see my (minor) changes to get things to build by diffing these two branches.

I've updated the first post with the latest release. This includes a backwards incompatible change. Clients and servers both need to run either the old version or this version. Otherwise the clients will hammer the server with connections, only to be disconnected over and over. I suggest server operators let everyone know the time they will be updating, and everyone else make their best effort to update their clients at that time.

Assuming blocks are generated roughly every ten minuets what I can do is generate a block by myself for the full 50 BTC for about 9 minuets then hop on to the server and pump a fast hash rate the server will calculate that I should get some bitcoins even tho I have not helped out a lot. If you count Hashes that are sent it will fix this. Also if some one disconnects 10 seconds before the block is found and they where the leading hash speed they get nothing and everyone else gets a lot more then they should.

If a client disconnects who was generating a large amount of hashes, and the block was subsequently solved, then he wasn't involved in the creation of the block at all. It doesn't matter if he provided 99.99% of all hashes up to that point if none of those hashes generated a block. One and only one client generates the block. You value total hashes contributed more than hash rate at a point in time, but others may not value this distribution method as much as the current method. Some may think one method is more fair than the other. Both methods will be available in the next release, and the server operator will need to decide what to use.

not sure if i like the count-all-hashes-idea,
it kinda erases the lottery-style of bitcoin.

Well, as you can see, some people like the "count all hashes contributed" approach, and some prefer the "connected client hash rate" method. I'm in the process of uploading a new version which includes the new method.

and why do you expect the pool to get "the next" block?
it's not only you and the pool on the network, there's others creating blocks all the time and you might get nothing for a very long time.

Is the other one not flawed then Assuming each block is generated every 10 minuets can I not connect a lot of C/GPU power for the final minuet and get a bigger share ever tho I did little work.

I'm at a loss to understand why you think sending a deluge of valid hashes near the end of block generation, or any other time for that matter, would somehow result in a flawed implementation. The hashes are either valid or not. It doesn't matter how many are sent, or when they are sent. They are either valid and counted, or not valid and discarded.

BUG
If I close all my miners and restart them I lose all the Coins from the current Block that i should have received. Maybe use a table or array to store address in memory so people on the go can use it or even if there internet goes out.

That's not a bug, that is how it was designed to work, and you're not losing anything, as no blocks were generated while you were connected. You need to be connected and actively contributing to get a share of the coins. Now I am currently working on an alternate distribution method that would count all hashes sent to the server since the last solved block, and distribute based on that. The server operator will have to select which distribution method they want to use.

Some changes I had to make to the latest source to get building on Linux:

1. I had to add the following lines to the end of cmake-bitcoinr/CMakeLists.txt

IF(NOT WIN32)
TARGET_LINK_LIBRARIES(bitcoinr pthread)
ENDIF(NOT WIN32)

It needed pthread to link on Linux. I made it 'NOT WIN32' in case it's needed on Mac too.

2. In src/remote/remotebitcoinheaders.h, removed the "../blah.h" includes and replaced them all with a single:

#include "../headers.h"

This got things included in the right order. Not sure if that's the optimal fix.

I've updated the first post with the newest source and binaries.

The main changes are

Decreased bandwidth utilization, especially for incoming bandwidth to the server. This will only take effect is both server and client are running this new version. If there is a mismatch between client and server version, the bandwidth usage will actually be slightly increased.
More details displayed by the CPU miner, including the number of blocks generated by the server since it was started, and how many coins the client will get if the current block is solved. Please note that the first block sent by the server to the client won't have any coins being distributed to the client because it has effectively 0 hash/s at that time.

If you want people to connect to you, create a new thread stating such, in the main post give your IP address, and link the binaries and a simple how to.

Keep it up-to-date if new releases come out.

I started a webpage with details: http://www.bluishcoder.co.nz/bitcoin-pool/

~~I'll start a thread once I've got the GPU situation and/or some linux binaries sorted.~~
Actually probably better just to a thread. Thread here: https://bitcointalksearch.org/topic/join-a-pooled-bitcoin-mining-effort-2027

My GPU mining computer melted... (stupid Aussie summer heat)... One I have it back running (1 week approx) I'll volunteer to join for debugging.

Unfortunately it seems there's no GPU enabled remote miner client. What is your GPU setup? CUDA or OpenCL? Windows, Linux or Mac?
