OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[Queelis]

Finally my newb time is over so I can thank ckolivas for his great miner.

Initially I was about to ask about 2.0.8's strange behaviour (upon restarts my hash rate would change between 84 and 64 Mhash/s, which is not insignificant). Version 2.1.0 seems to have fixed that (though q for quitting is broken, I can affirm that) - so now I have an average of 84.7 Mhash/s for my Radeon 4830, which is much higher than the table at Mining hardware comparison seems to suggest (and at 69.7 Mhash/s, higher than I was getting with GUIminer). Cheers!

Hi Con, It looks like api-example.c, api-example.php, API.java/API.class and miner.php didn't get packaged up in the 2.1.0 source tarball. I see they are there in GIT but the README implies they are included in the main distribution.

The spacing and misalignment problem is still with us, in this instance due to double-digit rejects for a couple of GPUs.  But as indicated by the hyphen borders, LOOK AT ALL THAT WASTED SPACE ON THE RIGHT!!11!!1  Some field widths could be increased.

My plan is to fix this; might take a few days (due to my schedule, not coding time).  If someone else wants to do it, please let me know.

Here is my quick and dirty Perl implementation of api-example. Just copy and save this as api-example.pl. Note, you need to have the JSON Perl module installed to use this (perl-JSON for RH-based distros).

Code:

#!/usr/bin/perl -w
#

#
# Simple Perl script to query and parse cgminer API stats in JSON

#       Bugfix: Support for multi element arrays in responses

# v0.01 12/28/2011 JinTu (jintuNO@SPAMpraecogito.com)
#       First working version. Supports cgminer 2.1.0 API JSON format
#

use strict;
use IO::Socket;
use JSON -support_by_pp;

my $cgminer_host = "localhost";
my $cgminer_port = "4028";

my $remote = IO::Socket::INET->new(
                        Proto           => "tcp",
                        PeerAddr        => $cgminer_host,
                        PeerPort        => $cgminer_port,
                                  ) or die "cannot connect to port $cgminer_host:$cgminer_port, $!\n";

my $command;
my $parameter;
if ($ARGV[0]) {
  # look for parameters in addition to a command
  unless (($command,$parameter) = $ARGV[0] =~ m/(.*)\|(.*)/) {
    $command = $ARGV[0];
  }
}
else {
  # We didn't get an argument so default to sending summary
  $command = "summary";
}

# Send the JSON query
if ($parameter) {
  print $remote '{"command":"' . $command . '","parameter":"' . $parameter . '"}';
}
else {
  print $remote '{"command":"' . $command . '"}';
}

# Now read the result
my $response = <$remote>;

print $command . " returned \'$response\'\n";

# Now parse the JSON
my $json = new JSON;

# these are some nice json options to relax restrictions a bit:
my $json_text = $json->allow_nonref->utf8->relaxed->escape_slash->loose->allow_singlequote->allow_barekey->decode($response);

foreach my $tlc (keys %{$json_text}){
  print "\n$tlc\n";
  if ($json_text->{$tlc} =~ /array/i) {
    for (my $i = 0; $i <= (scalar @{$json_text->{$tlc}} - 1); $i++) {
      print "->[$i]\n";
      foreach my $cat (keys %{$json_text->{$tlc}->[$i]}) {
        print "\t$cat=" . $json_text->{$tlc}->[$i]->{$cat} . "\n";
      }
    }
  }
  else {
    # This is not an array so just print it
    print "\t" . $json_text->{$tlc} . "\n";
  }
}


# make sure we close the socket
$remote->close();

This will give you output like the following:

Here we go again    The idea was to leave those since they're ever increasing and you'll never be able to guarantee enough column width and alignment.

If your using Windoze that's kind of normal operation for most of us as its a known Windoze bug.  There are several older posts mentioning this if you want more details.

If you want guarantees, DeathAndTaxes is your man, or at least his moniker suggests so.  Regardless, I offer to replace the current layout...

if not yet done, try:
sudo aticonfig --install --adapter=all
sudo reboot

Did that after installing fglrx. I know I'm missing something simple.

Have you started Xorg?

Xorg shows in top.  I don't think startx works through ssh???

Looks like people are getting it on linux too now. Anyone want to get a core dump and get a backtrace? (If that's within your capabilities of course). Of course I'd debug it but it doesn't happen here... then again I don't have any GPU mining to test it on right now

You're right, thanks. Naughty Kano... anyway I'll fix it in the git tree.

Well at least I know it's not my code at fault. Shame though...

Not necessarily implying your code is at fault, but a data point:  here, no seg fault with 2.0.8, seg fault with 2.1.0, no driver change.  Catalyst 11.6, Ubuntu 11.04.

How are rejects for everyone now with the new code? They should be the lowest ever.

Looks the same for me but I always had low rejects using Bitminter pool & cgminer (<0.1%).

where whitespace to the right of any ":" or "|" or "/" is subject to being used for digits as necessary.

0.1% sounds good.

There will only be a difference in this release if multipool is set up, and more so if you have switched from  your primary pool.
