Topic: New demonstration CPU miner available - page 5. (Read 386150 times)
I agree with ancow. The tools to do this exist already. Since cpuminer will run idle and niced priority, setting an ondemand cpu frequency governor with ignore nice load will do precisely what you want.
Now if that doesn't deter you, then sure there are ways I can implement this crudely on linux. I haven't got a clue how to do it for other OSs, nor do I care to figure it out.
Personally, I don't think building throttling into the program is the best way to do this, especially on Linux. You can use frequency scaling and CPU throttling. Also, you can set your frequency governor to ignore niced processes (at least for ondemand and conservative), keeping the CPU speed down when nothing else needs the higher frequency. Works quite well for me.Also, at least with some distros, there's a tool called "cpulimit" that will periodically put your process to sleep and then wake it again that could achieve the desired effect.
[...] power usage and heat generation. Of course they may be issues in their own right. Is there really a demand for this?
I for one would like to have it. I would have been a long time user of BOINC if it weren't for this.
Yeah but you do realise that at the current level of difficulty (which will increase soon), it would take a modern cpu over 50 years to solve one block successfully? Slow it down even more and it's... never. Of course you could use them to add MH/s but even then 1GHz of modern CPU adds about 1MH/s, so a throttled 3Ghz machine would only give you just 1 MH/s per core. Which really is... nothing by today's standards and will be even less as time goes on.
Now if that doesn't deter you, then sure there are ways I can implement this crudely on linux. I haven't got a clue how to do it for other OSs, nor do I care to figure it out.
I was more thinking that even at a low hash rate, 5k of PC's all connecting to one or two pools, would equate out to maybe about 300GH/s... kind of like distributed processing. Not only does this happen, but at a low cpu usage, it can run all the time in the background and the users won't be affected.

hi all... im experimenting with using this on a few different types on machines and i havn't found anything for the following question:
is there a way to throttle the minderd.exe process to say take only 35% of cpu when busy? and maybe 90% when idle ?
is there a switch?? i can open numbers of threads, but i can't actually find a away of controlling those threads.
The reason is i'd like to deploy this on a lot of workstations im looking after, roughly about 5k of them, but i need to keep control over what and how they are utilising the cpu usage.

No there is not... yet(?) The threads run at ultra-low priority and should not have any impact on the machine at all except in terms of power usage and heat generation. Of course they may be issues in their own right. Is there really a demand for this?

I added some ifdefs to cope with distributions that still have older headers so if you grab my latest git tree (from the master branch) it should build for you.
Thanks. Git branch is working now. A small contribution is going your way.
Success!
I can now compile the latest code, thank you so much for your swift fix there team
Is the 4way algorithm still the best?

Im trying it with an Atom 330 that is reported to have SS2, but I get better results with c and cryptopp (almost identical results with both).

Version 1.0.2 released.
Changes:
Christian Ludwig (2):
Fix libcurl include path
configure.ac: Beautify yasm test output
Jeff Garzik (3):
only read processor count via sysconf on non-Windows platforms
Fix number-of-threads init logic on Windows
Version 1.0.2.
ckolivas (2):
Linux + x86_64 optimisations.
Cope with older linux kernel headers that don't have the newer scheduling

cpu-miner.c:43: error: ‘SCHED_IDLE’ undeclared (first use in this function)
Your OS needs to update /usr/include/sched.h to include this definition.
If you add
#include
does it fix the problem for you?
I can get the tarball 1.0.1 to compile OK however the source from github gives the following problem when compiling on debian 6 (amd64):
I get the same error with the code from ckolivas' repo

Standard advice -- your autotools installation is old or broken. Use release tarball.
