This warning appears here with PyOpenCL built with NumPy 1.5.1.
No warnings if using NumPy 1.4.1. I'll try to fix this in poclbm.
Topic: Warning: overflow encountered in uint_scalars (Read 2596 times)
Well, I think it's because I'm still using python 2.6.
With 3.1 this doesn't happen but I don't notice any performance difference.
With 3.1 this doesn't happen but I don't notice any performance difference.
Also happens to me in Linux, driver 10.12 and SDK 2.2. On all of my Radeons, 5570, 5770 and 5870.
I noticed this started when poclbm switched to the ArtForz kernel. In fact, on 5570 an older version is faster, and on 5770 there is no noticeable difference, so I keep using the older version for them.

I get this like 5 times every time I hit a share

This only happens in linux, in windows this does not happen. The payouts and shares/m are about the same. (I think linux has a bit more.)
System:
AMD X4 CPU
AMD 6950 with 6970 bios (This happened before I flashed the bios.) Furmark shows no artefacts at stock clocks.
Gentoo GNU/linux
ATI Stream 2.2
Momchil's gpu miner
Anybody else getting this.
It doesn't seem to affect mining but is kinda strange.
