generation slowed down dramatically
February 22, 2010, 01:22:37 PM
Am I the only one seeing minuscule generation lately? It was decent
until around 20:00 GMT February 21st, but after that my machine (4 core
I7) produced only one block for entire >12 hours. And there isn't
even a clue for new difficulty hike in the debug log.
Here are my possible scenarios:
1. Some big BC bot came along.
2. Someone is trying some kind of DoSing the system.
3. Someone built a bitcoin mod with GPGPU (CUDA or sorts)
support.
4. Some kind of growth problem (i.g. we reached first of a kind
network size and there is problem with that).
Ideas?

Ideas? I would want a copy of this hypothetical CUDA-enabled client.
However, I doubt that GPGPU acceleration would affect generation speeds
very much. Only the most expensive of modern graphics cards have a clock
speed of over 1 Ghz, after all.

No problem here. Other clients just happened to generate those blocks
before you.

Just a random streak of bad luck. It looks steady to me.
Competition doesn't have an effect until the next automatic retarget
adjustment, and we haven't reached the next one yet.
The adjustments are every 2016 blocks. To calculate our progress
towards the next one, divide the block total by 2016. The fractional
part is how far we are to the next one.
My back-of-the-envelope projection: 42032 blocks/2016 = 20.85 = 85%
of the way. About 1.5 days to go until the next one. That'll only be
about 10 days since the last one, the target is 14 days, so 14/10 = 1.4
= around 40% difficulty increase.
