My system.
- Intel i7-4820K
- 32GB host RAM
- GTX780 with 3GB
- Windows Embedded Standard 7 (64bit)
- Visual Studio 2010 with CUDA 5.0
I have allocate total 16GB non-paged memory( 8 * 2GB ) at kernel mode.
Receiving eight( 2GB x 8 ) virtual memory space, the attempt to cudaHostRegister with cudaHostRegisterPortable option.
However, it has been successful in random is not a success all. (For example, five out of the eight, six)
I make a success of up to 6 times.
I looks like there is a limit of 12 giga about.
Why a successful random wonder what?
Is there a size limit?
Answers please.
