I'm ready to upload the new MMC Pools Tool V1.0,
it provide desktop real time miners statistics of your favorite pool:



New feauture:
Multi wallet support (1 click to check miners status as well as HPM).
One click data plot and analisys.
New stats tool (plot option).

Windows only binary and source code.

badbonez - I had that issue when using machine with 8GB of ram but 24 cores.

Currently, this miner requires 1GB of RAM per thread. So what I ended up doing was using
6 threads - which uses 6GB, and then use another miner that only uses 1GB for the other 18 threads.

I see now I have a similar situation.  How do you tell the miner to use 1GB for the other 18 threads?

I used a different optimized miner in the other thread. Alternatively I would suggest if you can get more RAM - try on one machine and see how much it improves.

After all it's MEMORY coin :) It should benefit it! :)

According to my cloud server specs (cat /proc/meminfo and cat/proc/cpuinfo) I have 24 threads and 24GB RAM.  But it does not work if I specify 24 threads, I can only get 12 threads to work.  If I try to run another instance with 12 or fewer threads, it just slows down the entire process, so that I still only get about 11hpm.

I have posted detailed specs here:

https://bitsharestalk.org/index.php?topic=1630.msg28357#msg28357


Any ideas?

With a dual L5639 I get 13 hpm on 24 threads, not a huge improvement over the previous miners, definitely not 300% (btw I'm using Nehalem binary)

I'm just trying to get the miner to run on all 24 threads.  When I try just 12 threads, I get about 11HPM, I was hoping (maybe too optimistic) that 24 threads = ~22HPM.  But I'm paying for the 24 threads on the cloud server, I want to use them all.

Trying to regiser - https://secure.mmc-wallet.com/#/signup - says Unable to Connect.

I appreciate the help!  I am using a 6-core (L5639), 24 thread Unbutu 13.04 server.  When I run ./yam -c yam-mmc.cfg it runs for about 20-30 seconds and then dies.  If I run yam with say 12 threads, it works fine.  But I'd rather not run multiple instances. (NOTE:  It will not work if I run 2x 12 thread instances. If I run a 12 th and a 8 th instance I get a combined HPM of ~12.  About the same if I just ran a single 12 thread instance.)

I have added my configuration file, cpuinfo, meminfo and output of the miner below.

Unfortunately, here we have nearly the same situation as we had with cloud servers running first versions of PTS mining (before yam, it was jhProtominer M7c-M7h, probably you followed a bit).

I recommend you the following:

1. Post here output of the miner that comes right after banner message - there is info on algo in use, number of threads selected and optimization compatibility checks - there we will see if AES-NI is really working
2. Try running it with ONE thread. You shall get ART value within reasonable time and factor out many potential issues.
3. Post here output of numactl --hardware (this is TYPICAL that cloud services DO NOT properly support NUMA, to be honest I am NOT aware of any that does that right, as well as memory management is completely unacceptable for high performance computing).

From what I see, you have multi-socket system (some Dual Xeon E5-26XX), so proper NUMA support is critical. Default memory allocation policy for such systems is typical to be Interleaved, causing huge underperformance under heavy memory load due to QPI bandwidth limitation, which is exactly our case.

Note that miner updates statistics in between rounds, so not showing statistics means that round takes way too long - compare this with physical machine - some SB, IB or Haswell i7.

As of crash, which EXACTLY CPU is there and which build do you use?

yvg1900

P.S. In other case I would not support cloud services and low end configs because of they simply using outdated and improperly configured software. But let us try to figure out what we can do.

At the moment I believe that there is no point running yam M7j on non-AES-NI configs - I expect it may be slower even than original miner, because of non-AES-NI codepath did not get enough attention from me. Probably for next versions.

As of less memory usage, I am working on that. Major part of the optimization was to reduce data exchange and contention between cores, that's why separate buffer per thread used. Reverting back to old schema is possible in theory, but it is complete rethink of the optimizations made and needs time. You can imagne even this set of optimizations took long time to get implemented.

As of miner behavior under low RAM situations, there is absolutely no special handling for that except for some null pointer checks. At first, applcation performance will degrade due to swapping (if you have one configured - I don't) and if there is not enough RAM even in case of swapping, it will (may) just crash, but will do so at very early stage.

If you are not getting hashrate, then system runs extremely slow due to swapping (=> more RAM or less threads), inter-socket data exchange over QPI (=> numactl or proper affinity setup) or no AES-NI. There is an ART parameter (Average Round Time in milliseconds) that shall be less than 60000 in regular cases. 45000 is typical, less than 30000 is fast.

If you reduced number of threads due to RAM constrains, consider using av=2 or av=3 to gain from non-HT algo variations.

yvg1900

P.S. At the end, it is MemoryCoin :) It is supposed to consume A LOT of memory for PoW :)

Thank you for your reply.  Here's a more specific situation:

I have a cloud server with 24 threads and 24 GB Ram which DOES support AES-NI.  My config looks like this:

threads = 0
mining-params = mmc:av=1&aesni=on
mine = getwork://[email protected]:80:8880:8881:8882:8883/mmc
mine = getwork://[email protected]:8080:8081:8082:8083/mmc
#proxy = socks4a://127.0.0.1:9150
compact-stats = 1
print-timestamps = 1

When I run yam ("./yam -c yam-mmc.cfg") I get about 20 - 30 second of output like this:

And then it crashes.

I can see that it has contacted the server, "work.mmcpool.com: On-line" but no hashing,  I am using the Generic x64 Linux miner on Unbutu 13.04 (x64). 

Any ideas?  Thanks.

PS:  When I look at hugepages (cat /proc/meminfo | grep AnonHugePages)

I get:

AnonHugePages:         0 kB

Not good?

Two questions:  What happens if there is not enough RAM per thread?  (For instance, I have 4 threads but only 2GB RAM.)

Can you explain why I am not getting a hashrate?

aesni is off because this server I am using does not support AES.


Thanks!

How do you run this in OS X?

I built a shell script with the following (and chmod to 777):

Code Select Expand

#!/bin/bash
yam --config yam-mmc.cfg

I have yam-mmc.cfg, the yam application and this shell script all in the same folder.  When I run this shell script from the terminal it tells me
yam:  command not found.

(and yes, I changed directory to where the yam app and .sh file are stored.  I even tried by just dragging the .sh file into terminal.  Same response.)

Thanks.

Nevermind.  Forgot to add ./ to the yam command.  Should be ./yam in the .sh file.

its easy

just edit yam-mmc.cfg or  yam-pts.cfg depends on your mining coin, then just run miner with 1 of these commands:

yam --config yam-mmc.cfg
yam --config yam-pts.cfg

Code Select Expand

git clone https://github.com/glitchman/mmcminer.

Naturally, that won't work here as this file is on rapidshare.  I tried

wget http://rapidshare.com/share/3BACFA7FD98BE772D770BBFFC2C900E3/mc2miner-0.1d-linux64.tar.gz which makes a something called mc2miner-0.1d-linux64.tar.gz (it's listed in red when I look at the directory).  Now what?  Or what do I need to change some syntax?

Hi, you could follow these steps:

1) download the file to windows
2) install a sftp client (such as https://filezilla-project.org/‎)
3) connect to your remote server (the protocal is sftp) with your login credentials
4) upload to your server

maybe not the optimal but it works..

Excellent!  Thank you.

Exactly how much cpu time are we donating to support the next version?
I've seen the message come up more than three times in the past few hours.

In the edited OP he states that it mines for 30 seconds to start and 30 seconds every hour.

no need to compile and install, as it is binary...
