BFGMiner
BFGMiner is a modular ASIC, FPGA, GPU and CPU miner written in C, cross platform for Linux, Mac, and Windows including support for OpenWrt-capable routers.

Features
- A variety of device drivers for Bitcoin (SHA256d):
- Butterfly Labs’s BitForce SC (ASIC) product line
- Avalon ASIC mining rig
- Butterfly Labs’s FPGA BitForce Singles and MiniRigs
- Enterpoint’s Cairnsmore1 FPGA mining board
- FPGA Mining X6500
- Qi Hardware’s Icarus and Lancelot FPGA mining boards
- BTCFPGA’s ModMiner Quad FPGA-based mining device
- Ztex’s FPGA boards
- OpenCL GPUs, such as AMD Radeons
- Kernels (including BFI_INT patching): Diablo, DiaKGCN, Phatk and poclbm
- VECTOR support
- Dynamic intensity that keeps desktop interactive under load and maximises throughput when desktop idle
- Integrated overclocking and fan control (including automatic adjustment, if configured)
- ADL device reordering by PCI bus ID
- GCN (79×0) support
- CPU (not enabled by default nor included in Windows build)
- Coming soon:
- ASICMINER ASICs
- any other device provided for development
- Support for new getblocktemplate decentralized mining protocol
- Scrypt mining support for both CPU and OpenCL (GPU)
- Very low overhead free C code for Linux and Windows with very low CPU usage
- Long poll support – will use longpoll from any pool if primary pool does not support it
- epoll support for interrupting FPGA waiting when new work is available without timeout-looping
- Self detection of new blocks with a mini-database for slow/failing longpoll scenarios, maximum work efficiency and minimum rejects
- Heavily threaded code hands out work retrieval and work submission to separate threads to not hinder devices working
- Caching of submissions during transient network outages
- Preemptive fetching of work prior to completion of current work
- Local generation of more valid work (rollntime) whenever possible, as supported on a per-work item basis
- Prevention of stale work submission on new block (submitold also supported)
- Automatically detects failing pools and disables them
- Multi-device support (all or discrete selection)
- Summarised and discrete device data statistics of requests, accepts, rejects, hw errors, efficiency and utility
- Watchdog thread to restart idle threads but not crash machine if they don’t respond
- Summary displayed when quitting
- Supports multiple pools with multiple intelligent failover mechanisms
- On the fly menu based management of most settings
- Trickling of extra work to backup pools if primary pool is responding but slow
- On the fly enabling/disable/restarting of devices
- Device temperature monitoring (for devices that support it)
- Reuses persistent connections when possible
- RPC +/- JSON interface for remote control
- Ability to cope with slow routers
- X-Reject-Reason support
- Lots of other stuff I can’t remember. See options.
