If you pay slightly more attention to content of dropbox folder or other download areas, you'll see md5 sums and wallet digital signatures for all the files. So it is there from the Day 1.

Exact OS version? Physical mach or VPS? More details on config needed.

Yes, normally SPM converges to HPM at the end. SPM reflects actual solution finding, while HPM is pure performance metric.

Yes, Cfg HPM is the right metric.

Looks like you measured everything OK.

Can you please provide more details on CPU (frequency, etc) memory (# of channels and mem module characteristics) and mobo (vendor and BIOS version)?

I will look if I have similar config in my test labs.

Idle = No connection, standby to be used as backup pool of higher priority pool conn will break.

Binding the process to each physical socket performs roughly the same as taskset

Did you measure exact HPM values? Does OS really support NUMA? What is output of

numactl --hardware

SPM is a metric (Solutions Per Minute) that depends very much on luck. Brute performance metric is HPM.

Fact that you see much smaller ART means that many threads share same worker memory area.

Can you post here output from the miner where it shows Threads/Workers and memory size in use?

yvg1900,

Is there an archive with the previous versions of yam? I'm starting to test the new version but it seems that on some architectures, the older version was faster. Although reducing memory to 1 Gb is a great achievement, I'm all after speed now.

Thanks!

I do not support old versions. There are other improvements in new version, so I recommend sticking to it.

If it really underperforms, we shall try to find out what is exact reason for that - I carefully test any possible perf degradation case, and new versions shall be working AT LEAST as goood as previous ones.

You may wish to set m=1024*numberOfThreads and ensure miner allocated threads = workers (you will see these numbers clearly indicated). If that is the case, miner shall use EXACTLY the code from previous version. If not - let me know exact config of your system and I will make more tests.

This assumes that you only have 24GB and occupying less than 1GB RAM.
uses Screen and taskset.

12.5+ H/m

--Nehalem core

If your OS supports NUMA and numactl, it is better to bind tasks to phys sockets using

numactl -N 0 -m 0 -- ./yam -c yam-mmc-0.cfg
numactl -N 1 -m 1 -- ./yam -c yam-mmc-1.cfg

Using taskset leaves open possibility of cross-socket memory allocation, which causes major underperformance.

I notice that the new version doesnt have a constant 99.9-100% peg on each thread, it fluctuates alot between 92-98 on each threads and rarely pegs at 99.9-100%

Is this by design, surely such fluctuations would kill extra hashrate ?

That would be the case if you use m=1024 and many threads. In this case mining will suffer from inter-thread sync contention.

Max perf can be obtained when m=1024*numberOfThreads, which is exactly the config from prev version.

Ну и сюда.

Только что выпущен yam M7k. Фокус - на уменьшении требований к RAM при майнинге MMC, стабильности и производительности. Подробности - в readme.txt, на твиттер-ленте @yvg1900 и в англоязычной ветке.

MemoryCoin / New YAM version release
« on: January 27, 2014, 08:14:08 am »
Updated M7k version of yam miner is available. It contains reduced memory mode for MMC, improved performance and connection stability.
M7k version of yam allows efficient CPU mining of MemoryCoin with all threads even with 1Gb RAM used for mining.
yam M7k runs significantly faster on AVX2 CPUs (Haswell) and has improved CPU load profile for overclocked configurations.
yam M7k fixes disconnect issues with some MMC mining pools that use get work protocol.

As usual, download at

I have a Core i5 M430 processor. Yam miner gives the error. Processor is not compatible with you?

Any idea?

This CPU does not have AES-NI support. You shall switch off AES-NI support in mining parameters. Check readme.txt for information how to do this.

MMCPool hosted in Germany, Hetzner DC. It runs fine. If you have  connectivity problems please try another pool: mmc.1gh.com. Or you can use it as backup pool in yam miner.

Also please do not use port 80 - I'll remove it soon. i.e. keep only 8880-8883 in your config. Thanks!

1. I will change port priority - will move 80 to the back of the queue.
2. It seems that on the application level there may be some slowdowns. I performed massive investigation today, and discovered that this is miner closing connection after not receivibg anything from the pool after 5 seconds timeout. I will try with longer timeouts now and let you know my results. In worst case I will make this timeout configurable on connection level, so users can increase it.

Any info on stratum client?

I am looking into including support for it in next yam release.

Please PM me if you need assistance on that, I need at least conn info and basic details.
