I have actually always wanted to ask this question. It is somewhat off-topic but to a degree still related. Why is it that Bitcoin mining is now difficult to proceed to with a regular desktop computer? Most around this forum have made a point every time to mention that desktop computers cannot support Bitcoin mining software.

Since ASIC chips, which were built specifically for solving the mathematical calculations needed to mine Cryptocurrency, can do so many calculations per second it is near impossible for a normal desktop computer to do enough calculations towards the network to compare to what such a chip can do (in terms of hashpower).

Desktop computers can support mining, though (should you use a pool) you will be giving very little hash power to the network and therefore get next to no reward. If you are trying to solo mine and find a block, the chances of the pools finding the block is exponentially higher due to them solving a lot more calculations per second. To find a block yourself is near, if not, impossible with a desktop computer.

What multiple devices have the capacity and upmost technology to perform proper mining?

It depends on the algo and whether there is a miner available for the device. ASICS are available for sha256, scrypt
and recently x11. SHA256 andscrypt are hopeless with anything less. X11 hasn't yet taken a hit from the introduction
of the ASIC for it.

GPU mining is most efficient for most other algos and CPU mining isn't really worth it. However, there are a few
algos designed specifically to be difficult to implement on a GPU or ASIC. Some have a poorly performing GPU
miner or none at all. Look around the forum, there's always discussion about it, and be sure to use cpuminer-opt.

Do you have any list of altcoin can be supported of this kind of mining tool or software.. I hope someone can give supported list of altcoin and i hope someone can suggest to me which is the best profitable altcoin in this month?

Coins come and go too quickly, it would be too much work to try to maintain such a list. Go visit some pools
to see what coins they offer and what algo they require. There's a good chance cpuminer-opt supports it.
Some pools also display the coins' profitability.

cpuminer-opt v3.1.10 is available for download.

https://drive.google.com/file/d/0B0lVSGQYLJIZckxmTS1aRWQ5OEU/view?usp=sharing

This release adds support for the HOdl algo for CPUs with and without AES_NI. See the first post
in this thread for details.

WOW, my first donation. Many thanks. I'll have to make sure I don't post any sarcastic replies
to any of your mining questions, CPU or otherwise.

It works for me, hodl algo is there and works. Maybe you compiled without libboost. See the OP about requirement.

I have the dependencies installed:
 libboost-dev
 libboost-system-dev
 libboost-thread-dev

Can you she your ./configure ?

Thanks.
Nope, that does'nt work for me.
Still no HOdl in list.

Maybe I should include somehow required boost libs?

Just to point out, my pc is running ubuntu 14.04 and I install the entire libboost lib (libboost1.55-all-dev). Not individually.

Ok. Just to be clear these are my own steps.

1) Download cpuminer-opt-3.1.10.tar.gz and extract
2) ./autogen.sh
3) ./configure CFLAGS="-Ofast -march=native" CXXFLAGS="-Ofast -march=native" --with-crypto --with-curl
4) make -j4
5) strip cpuminer

Works for me.

the build.sh script is made for that, it does a "make clean" before

tested, and i see a good hashrate on the miner side, but seems to be only 150H/s on pools side (both suprnova and blockquary)

Yeah...  Wink
But recently we was discussing build.sh

I haven't looked at build.sh since the fork, I should clean it up.

It got me errors on AMD SSE2 compile and slower binary on Intel i7.

Epsylon3, thanks for cpuminer-multi, which is the main base for this great cpuminer!
