Bitcoin mining OpenCL VS CUDA

FeaturesBFI_INT support - Improves performance by 5-20% on supported GPUs
Efficient - Phoenix 2 doesn't discard any work unless it is invalid.
X-Roll-NTime support - Reduces load on pool servers by generating more work locally.
Free, open-source software - Phoenix 2 is available under the X11 license, and written in (fairly) well-documented and commented Python.
Modular kernels - If someone releases a more efficient kernel for our miner, it's as simple as dropping in the new kernel and using it.

CUDA Bitcoin miner not detected by CIS

For several weeks I was getting messages about missing dll (openldap.dll) always on start of Windows. It

When I run a process manually it presents itself:

RPCMiner 2013 (CUDA only) [Win32 only] (+ 5-7% eff.)

I did some modifications to original puddinpop's Bitcoin RPCMiner, and now it works slightly better!
Of course, this is true only for its CUDA version, since I have a nVidia card, and all modifications I did only

Unfortunately, all of changes are incompatible with CPU & OpenCL versions: you can compile CPU (Crypto++ or 4-way) or OpenCL version, but it just will not work. But this is not a problem: Crypto++ & 4-way algorithms are not so effective, as CPU algorithm in UfaSoft's miner, so if you want to do a
