that's unnecessary. I've found that the problem is exacerbated by the number of threads being used; perhaps he's only using 2 or 4 cores and therefore hasn't hit a hard limit yet?

I ended up just writing a script to restart the daemon if (when) cpu drops below a certain threshold, indicating the process has crashed... hacky, but good enough for now.

radiumsoup, can you share that script? appriciate

radiumsoup, please post a workaround script, you will help many people.
I'll put a link on www.MemoryCoin.info
Thank you!

this one: http://www.openssl.org/source/openssl-1.0.1e.tar.gz

Try adding

EVP_cleanup();

at line 136 of momentum.cpp

This might free the memory.

Mining several hours with 1.01 hashespermin, no block found.

How long will I expect a block with 1.01 hashespermin?

Thanks.

I have the new update running but i was using "setgenerate true 6" on my i7 2600 and was getting 2.2 Hpm so i could use work on the pc whilst mining. with the new update i can only use 4 or 8 of my threads and not the 6 which was running at 75% Cpu

4 threads is 50% Cpu @1.5 Hps
8 threads is 100% Cpu @2.6 Hps that is unusable

why have you removed the 6 i though you could go in 2's with how many threads you using ?

Running 6 threads may have looked like it was working, but was likely producing a high proportion of junk. Try running 2 instances together, one at 4 and one at 2 - you'll need 2GB of memory, but should see improved combined hash rate.

I have two quick q's:

1) I have downloaded and am using the 0.8.53 version and have 3 active connections. But it's been over 20 minutes and it is still calculating the hash rate. In addition, when I go to the console and getmininginfo, nothing happens, I get no response. Is it mining? Any ideas why I can't get the console information?
Did u run "setgenerate true 4" (or 8, 16, 32)? You can check the cpu usage to make sure it hit 99-100%

2) In General, what's the difference between the 4 processes and 8 processes? Does it affect the hash rate? 8 is faster? Any reason not to use 8 processes? (OK, that's 3 questions in one

)
The more processe (cpu core) you have the fast mining you will get.

Cheers!

I got things working by deleting the appdata files (except the wallet and blockchain). When it restarted, it immediately started mining and my hash rate was displayed. I tried the setgenerate true 32, but that didn't seem to do much more than the 8 processes I am using now. Might be my CPU...i7 3820 @ 3.6ghz.

Thanks for the assist!

Thought I would share my stats to help keep the momentum going

i7-3610QM @ 2.30ghz

"currentblocksize" : 2779,
"currentblocktx" : 8,
"difficulty" : 0.00001555,
"errors" : "",
"genproclimit" : 8,
"hashespermin" : 2.52846438,
"pooledtx" : 8,
"testnet" : false

I'm happy for an 18 month old laptop

Hmm...I have Intel i7-3820 @ 3.6 GHZ
24GB RAM

{
"blocks" : 565,
"currentblocksize" : 1193,
"currentblocktx" : 1,

"errors" : "",
"genproclimit" : 8,
"hashespermin" : 2.09299892,
"pooledtx" : 1,
"testnet" : false
}

Does this seem right? Compared to the laptop? Anything I can do to bump up the h/min? I tried to setgenerate true 32 but all that does is heat up my CPU, no hash speed increase. I can overclock, does that help?

Cheers!

Yer that's weird - I'm using win7 64 bit - client before the fork, maybe that's got something to do with it?

I opened it, went Settings -> Mine with 8 Processes .... and it just worked (Yaaay!)

Also, in all my tests the miner has basically been using 0 real memory, and putting everything into the virtual memory. There is a serious bug in the miner, and it impacts anyone not on a windows platform. I'm surprised nothing has been done about this yet, considering how freetrade is primarily concerned with a fair and even launch.

I believe you are talking of a different kind of virtual memory here. Mutliple mining threads accessing the same one gigabyte of memory to find the magic number for mining doesnt mean there is anything wrong - its just blowing up virtual memory totals -fold while keeping actual RAM clean. no swapping going on there.
If you are ineterested in the matter, use the program iotop and compare how protoshares and memorycoins each react when configuring more 1GB threads than GBs of real RAM available.
memorycoin will be less effecive if too many threads started, but well handle MANY more threads, protoshares will just start to swap or crash if thats exceeded too.

Hmmmm i beleive you could be very wrong. The problem is, the miner is paging tones of key search space onto the hard drive. This would have a MASSIVE impact on mining performance.

I'm surprised nothing has been done about this yet, considering how freetrade is primarily concerned with a fair and even launch.

While I could very well be wrong about any number of things on a wide variety of topics (just ask my wife! *rimshot*), my miners show almost no disk activity whatsoever.

iotop output while mining on a 32-core dedicated box:

Code:

Total DISK READ :       0.00 B/s | Total DISK WRITE :       0.00 B/s
Actual DISK READ:       0.00 B/s | Actual DISK WRITE:       0.00 B/s

It sometimes bursts to 15kB/sec, but that only happens every 10 seconds or so. It's much less than that on older 4-core boxes. Disk I/O is not the bottleneck here.

Delete the "rpcthreads" setting and use only the "genproclimit". It's the onlyone solution for now

try both last night, still got crash Huh

, now will try only genproclimit.
Any other suggestions?

I still to look the source code, but I've not find nothing yet.

Without rpcthreads my server was still up for three days without problems. Try and give a me a feedback. Now it's my time to sleep :-)

Good luck Cheesy
