Fail on screening test case mmp13 on version v1.1.x

[platinhom]

Describe the bug

CUDA runtime error on example screening test case mmp13 (both v1.1.1 and v1.1.0. It was OK in v1.0).

The last log as follow:

Expected behavior

No response

To Reproduce

1. Install Unidock by conda (new env, both v1.1.1 / v.1.1.0)
2. github clone unidock
3. run test case mmp13 (python3 run_dock.py). (Success in def case)

Environment

• OS: Ubuntu20.04
• CUDA: 11.3/11.1 (two testing machines)
• GPU: RTX 3070 laptop (8G) / RTX 3090 (24G)
• Uni-Dock version: v.1.1.1 / v.1.1.0

Hi,

I also have problems with the MMP13 example. The 'default' example runs fine but the MMP13 case stops somewhere halfway with the following error:

I'm fixing this problem recently.

Root cause identified: cudaMemset(&ig_cuda_gpu, ...) at monte_carlo.cu:1481 passes the address of the local pointer variable instead of the GPU pointer value. This corrupts the pointer, causing CUDA error 700 on subsequent operations. Fix: remove the &. See draft PR #178.
