Title: How to solve "Pool 0 not providing work fast enough" when Solo mining ? Post by: 28nmASIC on November 12, 2013, 07:28:06 PM Hi
I try to do solo mine on Mercury using the following configure in bitcoin.conf on Window 7(Virtual machine) and Bitcoin-qt v0.8.5beta listen=1 gen=0 rpcallowip=192.168.*.* rpcuser=user rpcpassword=password rpcport=9999 server=1 daemon=1 My Mercury status still only has 0 difficulty accepted CGMiner Status Running (pid=4409) Last Checked Tue Nov 12 06:41:10 UTC 2013 Avg.

Thank you PaulK Title: Re: How to solve "Pool 0 not providing work fast enough" when Solo mining ? Post by: os2sam on November 12, 2013, 08:33:48 PM In CGMiner you can increase your ST (Staged Work) by increasing your queue by going to settings and then queue and increase it from the default of 1 to 90 or so. That will help. Also setup some backup pools so that when Bitcoin-QT doesn't supply work fast enough you miner can leak some shares to standard pools. That way it's not a complete loss.
Also the only share you will see submitted to the solo will be block solves. So not seeing any accepted shares is normal operation for solo mining. Sam Title: Re: How to solve "Pool 0 not providing work fast enough" when Solo mining ? Post by: 28nmASIC on November 12, 2013, 09:05:54 PM Hi Sam,
I increase cgminer queue to the maximum 90, then the message is gone. Is it necessary to tuning its work queue as minimum or I can use queue with 90 without the effect? Do you have any command recommend to add more in bitcoin.conf to increase luck or performance? I plan to do Solo mine just only one month, it looks like lottory (@-@). cgminer version 3.6.6 - Started: [2013-11-12 20:36:04] -------------------------------------------------------------------------------- (5s):148.2G (avg):140.5Gh/s | A:0 R:0 HW:691 WU:1981.1/m ST: 92 SS: 0 NB: 5 LW: 0 GF: 3603 RF: 0 Connected to 192.168.1.99 diff 511M without LP as user user Block: 00063def6bf32304...

I plan to do Solo mine just only one month, it looks like lottory (@-@). I don't use the .conf file myself. I use "-Q 10" command line switch then manually increase it when I start the miner. The .conf file may allow larger values then the command line. As for tuning, I don't know how much difference other values will make. I use a queue of 60 to 120 as seems to vary how busy it keeps my BE's. You have allot more hashrate than I do with my meager 20GHs or so. Just make sure your client has as many connections as possible. Good Luck, Sam Title: Re: How to solve "Pool 0 not providing work fast enough" when Solo mining ? Post by: 28nmASIC on November 12, 2013, 09:32:33 PM Hi Sam,
I got the message again in next 10 minutes but the message occurred quite slower than using its default queue. That it means my bitcoin-qt reaches its capacities in the current environment, I have to set up backup pool follow your recommended. I don't know the other persons face this problem like me that using bitcoin client on Windows7 Virtual machine. Is it not generate the issue incase not using Virtual machine or using other OS? Anyone can confirm that solo mining is working normally on Windows7 when having hashing load at 140GH/s up? Note: Currently, I only have Macbook Pro with small hard disk so it needs to use VMware in case. Thanks PaulK Title: Re: How to solve "Pool 0 not providing work fast enough" when Solo mining ? Post by: os2sam on November 12, 2013, 09:43:06 PM What many people do who solo mine with high hash rates it so setup their own pool software. That's more complex than I want to get. So I just mine with the occasional "Pool 0 not providing work fast enough" message and not worry too much about it. And setup failover pools to take up the slack. I'm happy with that. Of course I would be happier with finding a block, but hey, can't have everything I guess :).
