Hello,

I made a major update and released SILENTARMY v3: a full Zcash miner with multi-GPU and Stratum support, for Linux: https://github.com/mbevand/silentarmy

SILENTARMY was initially written as a command line solver for the Zcash open source miner challenge. Its OpenCL kernel is more optimized than any other public Equihash solver, so as a result it was integrated into multiple other miners: Zogminer, Genoil's miner, eXtremal's miner, etc. But now SILENTARMY is in essence the "reference" SILENTARMY kernel miner. It will always have the latest "SILENTARMY kernel" optimizations. It's lightweight at ~4000 lines of code. It's pretty robust in my experience: my test machine has the AMDGPU-PRO drivers 16.40 running on 64-bit Ubuntu 16.04 and 2 GPUs (R9 Nano and RX 480 8GB) and I mined all day without any crashes.

My roadmap is:

• v2: support GCN 1 → DONE
• v3: make a full miner supporting multi-GPU and stratum → DONE
• v4: Nvidia support
• v5: Windows support?
