Ask for work... got blocks [1735316448-1735339999] (24696 Mkeys)
o ..snip.. o (24.48 Mkeys/s)

I assume that's a m4.16xlarge with -t 10

The +1.3 Mkey/s you get compared to what I see right now is because of  the -t 10 (you) versus -t 5 (me)

Actually I would recommend everyone to set up something between -t 10 and -t 60 (*) at the moment - depending on how long you want LBC to let run (do not forget: a graceful shutdown can take 60 - 120 minutes if you have -t 60). Because starting from -t 10 the startup cost is pretty diminished.

Also, I'd recommend to not stick to the "boring" 5/10/20 numbers. Try 11/17/23/37 or so (not exactly these, just dice some number if you want). You'll help to spread client-server requests more evenly and also you set up for your client more "individual" block sizes, which can actually help your client to get block intervals assigned that are being left for redistribution otherwise (if someone ends their client ungracefully).

(*) and not more than 60 if you haven't enough memory, because the LBC client has a small memory leak currently (you can see it taking more and more space within a round). Nothing tragic, but it's there - I noticed when I started a client overnight with -t 420 which actually became critical on my 16GB machine.

If you give me access to the machine, I can have a look what's wrong.

@unknownhostname

-t 10 is ok. Actually on AWS I wouldn't change that. If you really were into optimizing, you could let the instances in Europe have -t 10 and the instances in US/Asia have -t 17 (bigger network lag)

9 days to go - worst case. I take it all have their hook-finds or are controlling for presence of FOUND.txt at least daily.

LBC under MacOS Sierra (brew):

Code:
Unknown operating system: darwin-thread. Please report.

All packages have been installed successfully.

Code:
perl -V:myarchname

myarchname='i386-darwin'

Any idea?

Thanks in advance.

Cheers,
Ray

I know. But what's the reason?  Wink
Is there any incompatibility between Arch Linux and Darwin?

The problem is not the LBC client itself (Perl script) - this should be pretty much multi-OS portable

The problem are the generator binaries
http://unix.stackexchange.com/questions/212754/is-there-a-way-to-run-a-linux-binary-on-os-x

I have no Darwin system - or even the Apple Hardware here.

If someone would send a vmware-able MacOSX image my way, I could try to compile the generator for that target-OS.

The generator isn't open source, am I right?
I have such an image for compiling wallet sources with all the GCC, Xcode, Homebrew stuff.
I will upload it coming week.

Thanks Wink

User SlarkBoy has generously deployed quite some free giveaways in the LBC search space here and there.

The new BLF file and patch available on FTP Server (auto-updated on LBC restart) does contain these already.

While I do not know the privkeys of these, I am aware of the total amount and it's the biggest bounty program of LBC by far!

We will reveal the complete extent of these freebies once the fireworks of discovering them has started.

Have fun and a big cheers to SlarkBoy!

Don't take it personally  Wink It's more like no (performant) client for K80. (yet)

I had a look if some cloud vendor offers any Maxwell (M60) or Pascal GPUs (P100). I'm pretty sure with these LBC would work and it would even mean a nice performance kick. Unfortunately so far only promises and plans:

https://blogs.nvidia.com/blog/2016/11/16/tesla-p100-on-google-cloud-platform/
observe how "now available" in the subject = "will be available" in the 1st line of the text

I checked today. Nada. Only K80 and only in some locations.  Roll Eyes

I also am thinking about purchasing a dedicated 200 Mkeys/s machine...

Could you share with us some informations about how do you got this speed?  Is it expensive?

This pool could reach a very high speed if it were more people able to use a lot of CPU like you do.   Wink

Hi rico,
what about https://www.nimbix.net/jarvice/ ?
Allegedly with Pascal GPU support:
"...Nimbix is the only public cloud provider featuring NVIDIA’s latest generation Pascal Tesla P100 GPUs with NVLink, a high-bandwidth, energy-efficient interconnect that allows data sharing at rates 5 to 12 times faster than the traditional PCIe interconnects...."

Regards,
Janu$$
