hi! I've been away a couple of days. Still debugging the miner's windows issue: I'm almost sure it's a race condition. After that I'll try to check the android wallet with the api

It's hard to keep developping, especially when the price is so low.
THANKS gatra.

I've put a new one up, ~5% faster, mostly in the setup phase.  Also GCC has put "sub-optimal" code in some of the loops, gcc4.9 might do a better job as would some hand crafted ASM code, neither of which fill me with joy.


Another version, this one netted 2 blocks in ~8 days of run time (just the luck of the draw).  Biggest change is the use of a 30 second target to process each block (dynamically increases/decreases search space).  For me it's a little quicker as the setup phase overhead is proportionately smaller the larger the search space.  Aside from that the other changes would be to small to notice.

Yes, I'm happy to test.

I'm excited to be back to work on our stratum mining pool. At first glance everything appeared to be working. However after running for a while longer I noticed in increasingly terrible rate of invalid shares. Restarting the miner seems to do the trick but of course we don't want to require such frequent restarts!

I'll look into that. Are you willing to test debug versions of miner to help diagnose the problem? thanks!

nonce-pool, do you all see any similar problems?

I'm having only 2% to 3% rejects on nonce-pool, but my ch/s are much lower than yours, don't know if it has something to do.
Sorry didn't see your post earlier. This is on the pool side. We increased the time of the work log pruner to 600.  Work was being removed to soon.

hi!
I've been helping debug c.figgis' pool.

Thanks, we came to the same conclusion, 120 was too short, but we left it at 300, I think it would be enough and would put less stress on the server than 600.

I'm now debugging the windows miner.

regards!

the miner for stratum is here: https://github.com/gatra/fastrie
works, but it still looks like a hack, pending tasks:

- some code cleanup, change "connected to server using xpt" line Smiley
- more robust connection error handling
- investigate why it sometimes gives 0ch/s in windows but works ok in linux

will ask dga to merge after my branch looks better

stratum server has been here for a while: https://github.com/gatra/stratum-mining



ps: I only mine the testnet when I need to test stuff like this, yesterday I had 0 connections, but my node is always up.

Will do.  I also got one bug report that might be related to the windows issue - will fix some time in the next day or three.

My semester is starting, so I'll be a little less active in crypto -- please email me (dave.andersen@gmail.com) when you're ready for a merge, and I'll try to get it taken care of fast.

hey, just a question, in case you have time to answer.

how did you manage to compile the Riecoin miner on your Odroid? I have a U3 and have been trying to compile it without luck. I followed the instructions in the github directory:
https://github.com/gatra/fastrie/tree/stratum/xptMiner


Prerequisites:
Ubuntu: sudo apt-get -y install build-essential m4 openssl libssl-dev git libjson0 libjson0-dev libcurl4-openssl-dev wget

Building:
wget http://mirrors.kernel.org/gnu/gmp/gmp-5.1.3.tar.bz2 tar xjvf gmp-5.1.3.tar.bz2 cd gmp-5.1.3 ./configure --enable-cxx make -j4 && sudo make install cd git clone https://github.com/clintar/xptMiner.git cd xptMiner LD_LIBRARY_PATH=/usr/local/lib make -j4 ./xptminer -u username.riecoinworkername -p workerpassword

I'm running Ubuntu 14.04 Lts on the Odroid.

Any help would be greatly appreciated. I'm still new to linux, so the problem might very well be sitting in front of the screen Smiley

Thanks for your time.

I think it can interest you Gatra :

http://www.jl777.org/supernetwork-ipo/

"Understandably, I am being approached by coin devs who want to be part of the Supernetwork and I am evaluating them to find their unique advantage that brings value to the Supernetwork. While the Supernetwork will be able to work with all of crypto, eg. you can trade BTC and other crypto, only a select number will form the core of the Supernetwork. What this means is that the coins that are accepted will most likely get a pretty immediate boost in valuation. Nothing like what happened to BBR in most cases, but still the fact that the coin instantly is worth more when it has direct access to the Supernetwork and also gains revenue sharing, really does increase the value of the coin. This is a permanent and significant change to the outlook of the coin."


Datacoin could join the supernetwork. You're the type of dev he search.

What was the error? If I had to guess apt-get install libjansson-dev and try again.

Pool luck very poor i think the past several days at http://ric.upcpu.com/

Funny how primecoin gets 'praised' for solving world records but will produce an endless amount of coin.

I think Gatra was very wise to pick a fixed amount for total coin production vs. letting something run to infinity (potentially)

Correct me if I am wrong I believe Riecoin was announced and in development before primecoin.

Honestly so many coins have come and gone I just can't remember.

When primecoin came out I was able to cpu mine several blocks in the first few days until bigger players started jumping in.

Riecoin I missed the launch even though I knew it was in development being busy and distracted with other things at that time but from looking back I think riecoin was one of the hardest hit and most heavily mined coins at launch ever.

When you first proposed riecoin 2 , to 'increase' the proof of work and all a while back I initially thought it a risky move but if that is what it would take to get people on board AND to see riecoin be able to set some records it may be something worth considering.  I realize making a second one when you are still busy perfecting the first one (while balancing all of lifes other things) would probably be a lot of work and a pain in the ass.

I suppose it could alienate some who have embraced riecoin.

I wish I had more time to actually be able to make some type of contribution to the development of mining  or a more efficient miner.
Other than some coin projects I am involved with developing riecoin is one of the only other alt coins I regularly mine even though the few that I own would have probably been much easier to just purchase.

Sorry for the random thoughts and rambling on but when I opened my wallet today and saw how little riecoin I was able to mine in the pool the last few days I was pretty shocked. Difficulty right now is 1398.

hi!
sorry I've been very busy this week

I'll take a look at jl777's supernetwork

cinnamon_carter, thanks for your thoughts. Just to clarify: when I started to work on RIC, I first was going to name it primecoin, but I saw that the domains and github were already taken, so I had to choose another name. Then, primecoin was announced before RIC. By the time xpm was announced I had a working prototype but I hadn't had announced yet. So probably primecoin started development before ric, and also finished first, however it was concurrent and independent work since nothing was known about xpm until it's release. In fact I remember freaking out when first reading xpm's pre-ann and then being relieved when the details were revealed because I saw it was a different idea. It looks like time to market played an important role, and the market was starting to saturate on ric's launch.
In case we went for RIC2, it shouldn't alienate RIC holders, they should understand ist's a step forward and should be able to move from RIC to RIC2 seamlessly.

If you want to apply for you coin, write a PM to me with the following:
1. What makes your coin useful to the SuperNET. If your coin is just a clone of another coin with just some variables changed, there is no need to apply for inclusion into the CORE. It is just wasting of time. So, this means LTC cant get included in the CORE, however it can be in the spiral arms utilizing the power of the CORE.

2. Basic coin stats, believe it or not I have not memorized every coins current and future supply, emission curve, etc.

3. anything else you think will help me to understand your coin, the type of community, future goals, etc.

Fixed a bug in b15 reported by github user HenryHu.  This doesn't seem to affect the Linux version, but I wonder if it's related to the hang on Windows.  The fix has been pushed to git in https://github.com/dave-andersen/fastrie/commit/79e21cecb9bea07caac30c6a6b46735f558faee8

(It's a one-line fix that should not mess up Gatra's current effort at porting to stratum)

I've put a temporary alpha test binary in http://www.cs.cmu.edu/~dga/crypto/ric/alpha/xptminer-sse4-b15.exe

if someone with windows wants to see if that one actually works or not.  It probably doesn't, but it's worth checking.

Thanks to HenryHu for the report and precise identification of the bug!

(If anyone tests it and notices that this actually fixes a real bug on Linux, LMK and I'll push out a quick b16 build)

thanks again dga, I'll test with the new fix

also, an idea I received by "randomaxingman" that was discussed with dga, that would help us break the world record:

Quote
So what i suggest is a daily riecoin super block that is of at least minimum difficulty to set a world record. The reward for this  block could be based on the time it takes the network to find the block so as not to alter the emission rate. If such a block cannot be found within a given time frame then the reward for said time frame could jackpot to the next day so as not to impact network tx excessively.

I really like the idea but I see 2 issues with this:
1) timestamps are not enforced, so the protocol shouldn't rely on time frames very much. While all people are working on the superblock, a clever hacker would have free highway to mine standard blocks and force the timestamp in order to make it appear as it was mined after the time frame. If the super block is not found, then he has a lot of advantage.
2) It requires a hard fork. I don't like hard forks. However this may justify it

Let's think about how to work around issue 1....


another update: I'm not convinced by the supernetwork thing... must investigate carefully

Fixed a bug in b15 reported by github user HenryHu.  This doesn't seem to affect the Linux version, but I wonder if it's related to the hang on Windows.  The fix has been pushed to git in https://github.com/dave-andersen/fastrie/commit/79e21cecb9bea07caac30c6a6b46735f558faee8

(It's a one-line fix that should not mess up Gatra's current effort at porting to stratum)

I've put a temporary alpha test binary in http[Suspicious link removed]

if someone with windows wants to see if that one actually works or not.  It probably doesn't, but it's worth checking.

Thanks to HenryHu for the report and precise identification of the bug!

(If anyone tests it and notices that this actually fixes a real bug on Linux, LMK and I'll push out a quick b16 build)

I am delighted to confirm that the bug is fixed. The miner is finding shares just as quick as its Linux equivalent. Works like a charm on Windows.

Another version of the little ARM miner project.

A 5-11% improvements depending on sieve size (the bigger the sieve bigger improvement) by re-factoring part of the code in assembly.  To get the 11% I had to increase my sieve by about 30% (I am now sieving using the first 770k primes), so you'll need to increase '-m' accordingly.

Link is https://mega.co.nz/#F!6Y8ywRoZ!5ogMJEc2Teq5ckt9WClNpg.

Regards,

PS The last time I had to do assembler was for m88k, which should give you an idea of how long ago that was.

Awesome.  Thanks for testing.

I've put b16 online in the usual spot

  http://www.cs.cmu.edu/~dga/crypto/ric/

including windows .exe files.  Woo.
