python OpenCL bitcoin miner

[Mobius]

On the latest version (yesterday) I keep getting this error on my 2nd rig Ubuntu 10.10 Cat11.6 SDK 2.4  (2nd card 5830), identical to the 1st rig and the miner just hangs there, can't ctrl-c out and if I close the terminal - the whole machine locks up. The first card (5870 - Still working)

Any ideas or advice?

please bring back the old kernel
the new kernel is very bad for my nvidia card

Miner cant connect to deepbit, but it also cant connect to backup pool cuz "username or password not correct". They are correct and miner just stuck... Restarting results in going to backup pool or giving same message about login details.

BTW, can u add to circumstances to restart/go to backup

-when message 'verification failed...'
-when wrong username or password (cuz of pool problem or just user mistake)

Is there not a fallback command for Linux or what? It works on Windows...

Are you sure that you are passing a list of servers to "--servers" ?

Im getting similar errors:

EDIT: Also, a couple of miners have gone into a kind of a loop where it fails to connect to firs server, connects to second server and after 1 second tries to connect again to first server, fails, connects to second to second server, after 1 second tries to connect again to first server, fails,... (-failback = 1)

What do you mean?

New version today omits the --servers= part of the command line

update via command line
$ cd poclbm
$ git pull

get the options using
$ ./poclbm --help

Update your shell scripts or command line to reflect new option structure

Can enyone explain --estimate function? I dont get it. Also compiling a windows version would be nice.

From the read me in the sources, it looks like the window of time that the average rate is calculated 900 secs = 15 min window (the last 15mins of hash rates are averaged) and displayed.

New version is up

Changes:

- support for server provided failback hosts
- most of JSON-RPC fields made optional (to reduce pools bandwidth)
- increased default primary server retry interval to 10 getworks
- moved job processing to main thread
- improvements by gominoa, enolan @ github - options separation, server names, quiet output

[jgarzik]

- most of JSON-RPC fields made optional (to reduce pools bandwidth)

...and how does the client inform the server that it supports this feature?

From the server's perspective, it must support may different clients, and cannot know if 'target' or 'midstate' is optional without additional information.

[m0mchil]

...and how does the client inform the server that it supports this feature?

There is version in user-agent, server can determine miner and act accordingly.

[gominoa]

Please note syntax is updated. Use:

poclbm.py   user1:pass1@host1:port1#serv1   user2:pass2@host2:port2#serv2   user3:pass3@host3:port3#serv3

... instead of ...
poclbm.py --servers=serv1,serv2,serv3
... or ...
poclbm.py --user=x --password=x --host=x --port=x --backup=x

(miner will failover from serv1 to serv2 and serv3 if neccessary)

something is wrong with LP, I got rejected shares over 30 seconds after LP message shows up

[bitcoindaddy]

M0mchil, the help message for the failback parameter still refers to "2" instead of the new default "10":

Code:

group.add_option('-b', '--failback',  dest='failback',   default=10,          help='attempt to fail back to the primary pool every N getworks, [b]default 2[/b]', type='int')

With the last version of this minner I get less 10 MH/s in my NVIDIA GTS 250.

Again, message 'Deepbit is temporaly unavailable' - which for me is equal to connection problems, but failover fails... Failover module must be more exact

Did you check your own connection? If primary and failover fail, it may be your connections, I have not seen any connection fails in the last 24hrs
