Thanks

Okay, 100 Coin grant awarded to SlyWax from MCF. Looking forward to seeing what you do with it.

[stas]

blocks are lately generated every 1-2 minutes.
is it OK?

Are you sure the daemon works fine ? (bitcoind)
Each time I send something he create a new address.

I'm using the last version from github

This one will list only those unknown grant hoarder to see what they are doing (mostly just stacking the grant to win more grant)

Code:

tail -n +1 ~/.memorycoin/debug.log | grep --color=always -E \
"Candidate Elected:|Total of Voters' Balances:" \
| grep -Ev "MVTEoEoXmYzFydRfg5uNJRewt9tZ329fAN|MVTEoEo5LgYAMVh95oBBfGPj2eCDzkuJC3|MVTEoEomFfe7WuSEepMLsorgYzCQGBVw1z|MVTEoEoJ1vP6NHHcCTTBPy4bXfejbAqV5N|MVTEoEorLyJKdtGFXfFTt3Joevk7PeRvzh|MVTE7E3QD83ZLHivvBeNh8ZK1Eg313AEm6|MVTEoEoiMwtXEeHDUYfuwA9ZvbKSH8Jfqb"

New client - performance and stability improvements.

https://docs.google.com/file/d/0B-5Ax5kejTpMTGJPMTdRZ3V0XzA/edit?usp=sharing

This allocates specific memory for hashing, rather than continually allocating and de-allocating. It gives 15% to 20% performance improvment. It may also improve stability (stability problem 2).

However it doesn't start at all on my low-end PC, so I'm not going to post it in the main thread yet until I've got that sorted out. Shouldn't be an issue on medium to high end systems though. If it is, please post details about your system.

New source at github shortly.

using i7 870 @ 3.5 MHz here. hashpersec fluctuates between these 2 speeds. an improvement over previous release where it fluctuates between 11 and 14
so about 15%-20% improvement in speeds for me. just to clarify about the stability, i wasn't getting any crashes or problems ever since the first release anyway. so i won't be able to comment on anything about that.

Thanks - what OS and 32bit or 64bit?

[auctioneeeeer]

It only works for me if I specify genproclimit=<real number of cores>.  If I specify -1 trying to use Hyperthreading, it crashes.

Thanks - and what range of numbers can you specify? Is it only the exact number of cores that works?

I have 3 machines and it starts on all 3 of them.
i7 extreme 6-core, i7 extreme 4-core, 2-core celeron (ivy-bridge).

I can't comment on stability yet since I just installed it on all 3 machines. I have had crashes (many, many times) on all machines before, so I hope I can bring some good news later.

EDIT: Running windows 7 64-bit

[Sondey10mg]

I have a FX-8350 at 4.4Ghz and the newest client starts up and gives me 16.88 hashespersec

64-bit

[bahamapascal]

Downloaded the newest version and still did not fix the problem
Same message and the blockchain will not download, even thogh I am conectet to the network with 5 active conections...

Hmm - try adding this node by typing,

addnode 180.183.154.90 add

(and wait a few minutes)

Also try starting with re-index, deleting your block directory.

If all that doesn't help, send you debug.log file to memorycoincc@gmail.com and I'll look into it.

Hey thanks!
Just re-indexed the block directory and its working again

I have 4 core Ivy bridge, 8 core Sandy bridge Xeon, and 10 core Ivy Bridge.  Anything over 4 cores and I have to specify or it crashes.

win7 32bit

Think 32bit might be the factor with this release. It's working on my 64bit OS, not on 32bit.

Getting these numbers on 64bit Windows, i7 6 core Gulftown
I've not had problems on this machine, using "setgenerate true -1"

But on my Windows XP, 32 bit laptop, program crashes after only a few seconds. I've not investigated further, would you like me to try this latest version?

I can comment on stability now: still not very stable
All 3 my machines went down at block 2060 so it looks as if there are still some problems with grant-block processing.
As I mentioned before, once the problem is solved that you can load the blockchain while mining, this will prove the client is stable enough to run without crashing.

I have been stable for days, the trick for me was to specify using only the amount of real CPU cores you have with genproclimit=# in your memorycoin.conf file.  I have 5 machines running 24x7 now with no issues.

Yes, I read that in your ealier posts and tried that too but it doesn't work for me
On my 6-core i7 the client even crashed when set to use only 3 cores.

It's really strange why all my machines are affected so much while other forum members have no problems at all.
I will try one more thing: close my debug window. I always have this open to see if the miner is still on the right block.
Do you have your debug window open when your machines run stable 24/7 ?
