i got a problem and do not know if my system does not support the new architecture 6.x additional Unified Memory feautures (Especially PageableMemoryAccess and ConcurrentManaged Acess).
My device properties are:
Number of Devices: 1 Device Name: GTX1080 Managed Memory Property CC3.0(prop.managedMemory) : 1 PageableMemoryAccess: 0 ConcurrentManagedAccess: 0 UnifiedAddressing: 1
My system falls back to ZeroCopyMemory with Cuda 8.0 for cudaMallocManaged memory allocation, and i only use a single GPU (Only one Inside).
I ported one of my project to Linux and it works.
My device properties in Linux are:
Number of Devices: 1 Device Name: GTX1080 Managed Memory Property CC3.0(prop.managedMemory) : 1 PageableMemoryAccess: 0 ConcurrentManagedAccess: 1 UnifiedAddressing: 1
The difference is only OS, GPU driver and compiler.
Is the new PageableMemoryAccess and ConcurrentManagedAccess not supported under Window7 64bit with VS2013 or VS2015? (Only supoported under Linux)?
I would prefer to fix the problem, otherwise I have to install on two systems additional Linux and to configure an additional 4 systems and to port additional 3 projects.
