Architecture-specific notes:
ARM: No runtime CPU detection. The miner can take advantage
of some instructions specific to ARMv5E and later processors,
but the decision whether to use them is made at compile time,
based on compiler-defined macros.
To use NEON instructions, add "-mfpu=neon" to CFLAGS.
x86: The miner checks for SSE2 instructions support at runtime,
and uses them if they are available.
x86-64: The miner can take advantage of AVX and XOP instructions,
but only if both the CPU and the operating system support them.
* Linux supports AVX starting from kernel version 2.6.30.
* Mac OS X added AVX support in the 10.6.8 update.
* Windows supports AVX starting from Windows 7 SP1 and
Windows Server 2008 SP1.
The configure script outputs a warning if the assembler
cannot compile AVX or XOP instructions. In that case, the miner
can still be built, but unavailable optimizations are left off.
Usage instructions: Run "minerd --help" to see options.
Connecting through a proxy: Use the --proxy option.
