Hello,

I need some help with my OpenCL Miner for ZCash.  It finds solutions but the pool keeps rejecting as "too low difficulty".  I think when I find solution, im not sure i sorted the indexes properly.

Is there a test case that has input and expected output?

solo mining will be tough
zcash difficulty too high

btw did it work?

No, it didnt work.   Only a few shares got sent to the pool and they were all rejected due to too low difficulty.  Im testing my miner's solutions vs other 3rd party miners.  I must have a bug in my algorithm.  Ill post some more once I figure out anything.

Looks like it was a combination of slightly off algorithm for collision detection and majorly bugged hashing algorithm.  The hashing algorithm was causing the wrong solutions to be posted to the pool, and potentially correct solutions being lost.  I have started from scratch and it looks like solutions are being found and at a good rate too.
