Hello fellow miners.
I use poclbm without any major problems, but every now and then I will get an error message:
Verification failed, check hardware! (<hwID>, <32bit hex value>)
The general advice is to check one's hardware and I concur, but I want to look at it from a different angle.
My question is on the mathematical side. What exactly is tested to perform this verification?
I haven't seen it described anywhere.
