Total 0 solutions in 8429.2 ms (0.0 Sol/s)

Hello. I am running silentarmy on Ubuntu 14.04 with a Radeon 7970 using proprietary drivers.

When running $ make test it seems to run fine without any errors.

However, when running $ silentarmy --nonces 100, I end up with Total 0 solutions in 8429.2 ms (0.0 Sol/s).

confirmed, zero sols on Tahiti class GPUs

Also confirmed on 280x (also Tahiti).

Ok I'm looking into this. I have not tested any GPU other than the RX 480 and R9 Nano.

It looks like the determining factor is the GCN generation. Tahiti is GCN 1st gen. Silentarmy works on GCN 2nd, 3rd, and 4th gen cards, but not GCN 1st gen cards.

I investigated this bug and found that unaligned memory accesses was the root cause of silentarmy reporting "0 solutions" on GCN 1st gen hardware.

I fixed it in 5f68344

Now silentarmy should work on all GPUs, regardless of GCN generation.
