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.
