Re: [ANN] MON | Monocle | Merge Mined on VTC Vertcoin - No Premine - Scrypt-N

Maybe I am misunderstanding something, but does this seem right for my pool server?

mysql> select sum(monvalue) from stats_shares;
+-------------------+
| sum(monvalue)     |
+-------------------+
| 4.443734682918838 |
+-------------------+
1 row in set (0.02 sec)


linux:~/monocle$ ./monocled getbalance
1.00000000

Showing I should have 4.44 mon, but the wallet only has 1?

Just my machines running on this p2pool at the moment.  No payouts yet :|

Try getbalance ""

You will find you have unconfirmed coins, so you can't payout just yet.

I am in Batch 1 of the Alpha-Tech Scrypt Asics.  I have the deposit paid but my circumstances have changed and I am looking to see if anyone is interested in transferring ownership.  Please contact me off-list if interested.

Cheers.

Anyone running vertminer 0.5.3 on BAMT?

I got the latest version from GitHub and installed it with these instructions:
https://bitcointalk.org/index.php?topic=404364.msg4668635#msg4668635

It works, but seems I can't change GPU settings. Not from thecgminer.conf, not from the command line, not from the vertminer. Also, I can't see the card temps at all. The web monitor shows the temps just fine though on http://myip/cgi-bin/status.pl

Even the ./vertminer --help shows only these gpu options, so I suppose the rest are actually missing?
--disable-gpu|-G    Disable GPU mining even if suitable devices exist
--gpu-dyninterval Set the refresh interval in ms for GPUs using dynamic intensity (default: 7)
--gpu-platform Select OpenCL platform ID to use for GPU mining (default: -1)
--gpu-threads|-g Number of threads per GPU (1 - 10) (default: -1)
--lookup-gap  Set GPU lookup gap for scrypt mining, comma separated
--intensity|-I Intensity of GPU scanning (d or -10 -> 21,default: d to maintain desktop interactivity)

The only way to change core/mem is to set new defaults in gpu bios and flash the card with that. Which is a bit annoying when searching for the best values.. Undecided

Had this same problem two different times (two weeks apart so I forgot the solution) - be sure to run ./buildit.sh and NOT sudo ./buildit.sh. running as superuser seems to break the Open-GL / ADL stuff from what I can tell (assuming you copied the ADL_SDK .h files into the appropriate folder?)

I managed to make it myself. If you want to build it on BAMT it's quite easy:

1 - Open Root Terminal (or Run LXTERMINAL)
2 - Type: cd ~/Downloads/ *(if this folder does not exist, "type: mkdir ~/Downloads/" then type cd ~/Downloads/)
3 - Type: git clone https://github.com/Bufius/vertminer-gpu
4 - Wait for it to clone the GIT for vertminer
5 - Type: cp /opt/miners/cgminer/ADL_SDK/* ~/Downloads/vertminer-gpu/ADL_SDK/
6 - Type: cd vertminer-gpu
7 - Type: ./builtit.sh

You've succesfully built/compiled vertminer-gpu and now you need to set up a .sh (shell) that starts vertminer with your config of choice.

1 - Still in the Terminal window, Type: cd /home/user/Desktop
2 - Now type: nano start.sh and enter the following code:
Code:
export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100 #if you mine with 280x or 7970, set this to 200
export CGMINER_BIN=/root/Downloads/vertminer-gpu/vertminer
$CGMINER_BIN --scrypt-vert \
--config "/home/user/Desktop/config.conf \

3 - press CTRL + O (Write Out to file) - Save it as start.sh - then press CTRL + X
4 - Type: chmod +x start.sh
5 - Now type: nano config.conf and enter the following code:
Code:
{
"pools" : [
    {
        "url" : "stratum+tcp://yourpool.org:3333",
        "user" : "yourusername",
        "pass" : "yourpassword"
    },
],
"auto-fan" : true,
"auto-gpu" : false,
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "80",
"gpu-fan" : "0-100",
"intensity" : "SET PREFERRED INTENSITY",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "SET YOUR TC HERE",
"api-port" : "4028",
"expiry" : "60",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "SET YOUR THREADS HERE",
"gpu-engine" : "SET YOUR CLOCK HERE",
"gpu-memclock" : "SET YOUR CLOCK HERE",
"gpu-powertune" : "20",
"log" : "5",
"no-pool-disable" : true,
"no-submit-stale" : true,
"queue" : "9",
"scan-time" : "30",
"scrypt" : true,
"kernel-path" : "/usr/local/bin"
6 - CTRL + O and save it as config.conf - then press CTRL + X
7 - Type: screen and hit space
8 - Type: ./start.sh and this will launch vertminer-gpu with your config, and voila!

If you ever need to edit your config, open it with leafpad or edit with nano (i.e: nano /home/user/Desktop/config.conf)

Need help? Ask me. Want to throw some VTC to me? Vga61x3oxTV5CQDtqSW1KVdWjZnFeh3zJ9

The other thing I would do on BAMT is as follows:

Code:
mv /opt/miners/cgminer /opt/miners/cgminer-current
mkdir /opt/miners/cgminer
cp -R /home/user/vertminer-gpu/* /opt/miners/cgminer/
ln -s /opt/miners/cgminer/vertminer /opt/miners/cgminer/cgminer
cp /etc/bamt/cgminer.conf /etc/bamt/cgminer.conf.SCRYPT
Then put your config file into /etc/bamt/cgminer.conf

This will then start and stop with the usual BAMT commands, and a 'service mine start' or 'service mine stop' works.  Haven't got it working with the stats page correctly yet though, or through mgpumon.

I added +4 GB of RAM and I can mine. However, in a rig of 1 7950 and 1 280x, only the 280x is working properly with 290kh/s. The other one gets 7-8 kh/s. Any ideas?

Sounds like you need different settings.  in particular it probably isn't handling two threads well.  Can you put it into a different rig?
