jpegNPP on GTX 1080 error: NPP_NOT_SUFFICIENT_COMPUTE_CAPABILITY

I run jpegNPP sample of NVIDIA, and nppiEncodeHuffmanScan_JPEG_8u16s_P3R return NPP_NOT_SUFFICIENT_COMPUTE_CAPABILITY. As description of nppiEncodeHuffmanScan_JPEG_8u16s_P3R function, NPP_NOT_SUFFICIENT_COMPUTE_CAPABILITY is returned If the device has compute capability < 2.0, but GTX 1080 has compute capability is 6.1. Can anyone help me?

My system is:
OS: Windows 10 64bit pro
CUDA: 7.5
GPU: GTX 1080
Driver: 368.39

Use CUDA 8RC

Thank txbob. But unfortunately, 8.0RC has same problem.

sorry this appears to be a known issue in CUDA 8RC

you will have to wait until CUDA 8 production release at the earliest for a fix

Thank txbob.
Because our project has to finish in this month, so what can i do to temporary fix it in the meantime? or just waiting?
Is this issue only appears on GTX 1080?

I expect this issue would appear on any Pascal device.
