cgminer 2.0.8, Ubuntu 10.04
I first ran cgminer this evening on my newly-built 3x5970 rig. I access the rig from a Mac on a LAN via SSH. And since this was to be a first familiarization run, I started with solo mining, pointing cgminer at an instance of bitcoind on my Mac.
I use this small script to run it:
#!/bin/bash
now="`date +%Y%m%d%H%M%S`"
cd ~/miners
DISPLAY=:0 cgminer -c cgminer.conf 2> logs/$now.log
(Confidential to those helping me earlier today: I was logged in on the rig, so I dropped the sudo.)
When cgminer starts, I notice two things immediately:
It outputs a line on the terminal saying it started;
The GPU fan speeds increase substantially.
I also notice a little later via ps that there are six cgminer processes, which I hope is normal at one per GPU core. I also notice a file in the current directory:
-rw-r--r-- 1 root root 750880 2011-12-16 22:36 phatk110817Cypressbitalignv2w128long8.bin
The log file is created, but it's empty. Nor is there any further console output.
Here's the thing: it's not responsive to the keyboard. Keypress commands such as P, G, or Q are merely echoed. I wondered if this had something to do with using a remote terminal, so I tried running it locally. Whoops, I had specified an -intensity of 8 for all six cores, so in effect I was locked out of my monitor. (I know about "d" but the .conf was intended for remote use and I had forgotten that.)
So each time I ran it I stopped it (and dropped the GPU fan revs) by rebooting.
Here's the .conf file, based on the example that came with the source code:
{
"pools" : [
{
"url" : "http://192.168.168.123:8332",
"user" : "oboy",
"pass" : "supersekrit"
}
],
"intensity" : "8",
"gpu-engine" : "0-950",
"gpu-fan" : "0-85",
"temp-cutoff" : "95,95,95,95,95,95",
"temp-overheat" : "85,85,85,85,85,85",
"temp-target" : "75,75,75,75,75,75",
"auto-fan" : true,
"auto-gpu" : true,
"expiry" : "120",
"gpu-threads" : "2",
"log" : "5",
"queue" : "1",
"retry-pause" : "5",
"scan-time" : "60",
"temp-hysteresis" : "3",
"worksize" : "0",
"donation" : "0.00",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}OK guys, I have braced myself for looking stupid: why is it unresponsive to the terminal and producing no output?
Edit: I changed intensity to "d,8,8,8,8,8" to try another local run but I was still locked out of the monitor.
I said the log files were empty, but in fact each contains the "cgminer started" message.
And server=1. I've been invoking it with -daemon. And the -c is in a .sh, so it's not costing much.
