Hi. I've made some minor modifications to cpuminer that are x86_64 linux specific.
Here's the list of changes:
- Linux x86_64 tweaked version
- Uses sse2_64 algo by default
- Detects CPUs and sets threads accordingly
- Uses CPU affinity for each thread where appropriate
- Sets scheduling policy to lowest possible
- Minor performance tweaks
The changes aren't entirely portable but Jeff you might be interested in some or all of them.
