Hi Diego,


I am able to reproduce the issue by just loading a pdb file (2JUL), and with various other systems. First I change the representation to quicksurf, I set the quality to max, and move the slider back and forth. This consistently gives me this:

CUDA error: an illegal memory access was encountered, CUDAQuickSurf.cu line 1453

Best,
Andres

Hi Andres,
can you share your structure for us to test ?

Dear VMD team,

My VMD sessions are crashing when I try to use quicksurf, this is the error message I get:


CUDA error: an illegal memory access was encountered, CUDAQuickSurf.cu line 1453
terminate called after throwing an instance of 'prodlib::AssertionFailure'
  what(): Assertion failed: "m_resolvedSet.empty() : Scope destroyed while resolutions remain", file: <internal>, line: 254
Aborted (core dumped)

I'm running on Ubuntu with an A6000 on version 1.9.4a55 . Any help with this issue would be greatly appreciated.


Thank you,
Andres S. Arango
