[ANN][MTC] GPU Miner for Metiscoin - 35% FASTER on R9 280x

[girino]

Great news, just pointed my "hamsters" at your pool.
The new version of miner does not support -d 0,1 flag? i must start 2 instances of minerd for every GPU.

I had not much time to update the miner, so yes, you need two instances. I'll try to work on it today so we can solve it by tomorrow. Thanks for the support.

ALL BETA TESTERS UPDATE THE MINER PLEASE!!!

download the newer versions at the same place: http://girino.org/metisminer/

Sorry to all, the old miner had a bug that prevented it from finding new blocks. Technical explanations bellow.

Those who participated in the beta test up to now will share the bonus 50 MTS i had promised. See bellow for the shares each one will get. I'll contact you in order to send you the MTS.

Now, the technical stuff:

When writing the miner I got confused as to how the data was sent on the getwork protocol. I was auditing the shares submited to see why it took so long to find a block and found out that good hashes were being rejected by the metiscoind wallet. I found out that hashes where sent in "little endian" 32 bit encoding, while i was using "big endian" encoding. So a swap of the bytes was needed. I now fixed it and have tested if the hashes generated by the walled are compatible with the hashes generated by the miner (lots of debugging in the wallet to do this).

So, I thank you ll that participated in the beta up to now and urge you to update the miners so that we can start breaking lots of blocks!

PLEASE DO NOT LEAVE THE BETA TESTING, we still need to test lots of things in the miner and pool server.

The 50 MTS for the early testers will be split acording to the following table:

ID	Username	Shares	Est. Payout
5	AJIekceu4	3	0,045468324
6	breakbeater	1822	27,61442861
10	dggood	8	0,121248863
3	HHogan	1465	22,20369809
7	nixueyin	1	0,015156108

Thanks to all, and again, PLEASE UPDATE THE MINER AND DO NOT LEAVE THE BETA TESTS!

I can't download the new miner:
Forbidden You don't have permission to access /metisminer/metis-minerd-win64-cygwin-build2.zip on this server.

I can't download the new miner:
Forbidden You don't have permission to access /metisminer/metis-minerd-win64-cygwin-build2.zip on this server.

sorry for that, I forgot to change the permissions of the files (for some reason windows created them with chmod 700 instead of chmod 644. Anyway, should be solved by now.

NEW POOL -- BETA TESTERS WANTED

For the eager ones: http://pool.girino.org/
Miners can be downloaded here: http://girino.org/metisminer/

The new miner can operate in an efficient way, even in CPU-only mode?

Sources for Linux?

TIA

no cpu-only mode yet. As i cannot efficiently charge a developer fee on this miner, i'll release the sources only after the pool is stable and making some proffit. (or if a receive enough donations to keep the pool running for 2 or 3 months).

I might be working a CPU only miner on the weekend, and will probably release it as open source.

NEW EFFICIENT CPU MINER

I might be working a CPU only miner on the weekend, and will probably release it as open source.

For those of you who asked about the CPU miner, good news: The new version of the miner supports both GPU and CPU mining. As i'm not sure if the GPU version runs without a GPU driver installed, i produced 2 versions of the miner: minerd.exe which supports both CPU and GPU, and minerd-cpuonly.exe, which as its name says, supports only CPU mining.

as always, downloads are here: http://girino.org/metisminer

There are no news in the GPU miner, so you only need to update if you intend to do CPU mining.

Please enjoy all of you, and happy mining.

Hi, thank you for your efforts in making the CPU-only.

But it is not very efficient as I hoped.

By way of example, the present version for Win64 reports:

[2014-03-10 11:52:11] thread 1: 1278464 hashes, 116.94 khash/s
[2014-03-10 11:52:19] thread 0: 1272832 hashes, 128.75 khash/s
[2014-03-10 11:52:29] thread 1: 1169408 hashes, 128.53 khash/s
[2014-03-10 11:52:31] thread 0: 1287680 hashes, 117.47 khash/s

No share even after a long time, and then on the pool's site there are no signs that the worker is on-line and that is working.
Comparable results for the linux version.

For comparison, on the same machine the win version of xptMiner (1.5), however, shows:

[00:02:32] kHash/s: 316.90 Shares total: 0 / 0
[00:02:37] Share found! (Blockheight: 47112)
[00:02:40] kHash/s: 317.03 Shares total: 1 / 1
[00:02:48] kHash/s: 317.15 Shares total: 1 / 1
[00:02:54] Share found! (Blockheight: 47112)
[00:02:56] kHash/s: 317.25 Shares total: 2 / 2
[00:03:04] kHash/s: 317.53 Shares total: 2 / 2

And by the time the kHash stabilizes at about 340.

Maybe the problem is due to the Dif too high?

In this regard, before I never noticed, but a difficulty 116421.397088 is normal for MetisCoin?

PS:
The machine on which I effettuate the test is based on Athlon 64 X2 6000+.
I know, the machine is not very powerful, but that is available.

Yes, the share difficulty in my pool is too high for cpumining (currently set to 64), i think. I can lower it, but this should be something well planned since it can be unfair to those already mining. I'll think of some solution to this, to make cpu mining usable on the new pool.

The difficulty of 116421.397088 is not "normal" in the sense that it never got so high, i think. But that's just a sign that the coin is growing, which is good!

If i use this howcan i choose GPU ? and i need to use -d 0,0 like this for 280x ?

If i use this howcan i choose GPU ? and i need to use -d 0,0 like this for 280x ?

what Steps size is good for 280x ?

[girino]

If i use this howcan i choose GPU ? and i need to use -d 0,0 like this for 280x ?

on windows, there are two execs (and 2 bat files) inside the zip. open for cpu, the other for gpu. There is also a .bat file as an example of usage.

On linux you must download each version separately. The metis-minerd-linuxXX-build4.tgz is the GPU version, and the metis-minerd-CPUonly-linuxXX-build4.tgz is the cpu version.

If your 280x is the first GPU, simple launch it without specifying a device:

Code:

./minerd -u workername -p workerpass

If it is no the first device (in case you have more GPUs on the same machine), first list the devices:

Code:

./minerd --list-devices

it should show you the device numbers, like this:

Code:

Platform 00: AMD Accelerated Parallel Processing
  Device 00: Cedar
  Device 01: Tahiti
  Device 02: AMD Phenom(tm) II X4 B95 Processor

Take note of the right device and run (in this case, the 280x is "tahiti", so device 01):

Code:

./minerd -u workername -p workerpass -d 1

DO NOT use -d 0,0 as in your example, this will try to run it twice in the same device and may lead to inconsistencies and out of memory errors. If you want  to run on more than one device, in my case on "Cedar" and "Tahiti", run as follows:

Code:

./minerd -u workername -p workerpass -d 0,1

You can also use the gpu version to run o CPU, use:

Code:

./minerd -u workername -p workerpass -a metiscpu

As for your later question:

what Steps size is good for 280x ?

The default step size (19) should be excelent for 280x. less than 19 might make it slow, and more than 21 will take too long to complete each step, with no performance improvement.
