I used gpu on TX1 for Sift(a feature matching algorithm).After sevel minutes’ executing it crashed with the error warning:
gk20a gpu.0:gk20a_fifo_handle_mmu_fault:mmu fault on engine 0,engine subid 0(gpc),client 10(t1 3),addr 0x00000000:0x22400000,type 2(pte),info 0x00000a82,inst_ptr 0x148b56000

I don’t know how to locate the error ,and the file<cudaSiftH.cu>,line 247: safeCall(cudaThreadSynchronize());
Will you help me how to deal with this bug.Thanks.

Hi,

Could you share the source for us checking?

One possibility is compiling with the wrong GPU architecture.
TX1 GPU architecture is sm_53. Please remember to build the kernel with sm_53.

By the way, we have FAST implementation under OpenVX standard.
If you are interested in this, please install VisionWorks via JetPack.

Thanks.
