如何强制生成更高版本的cubin文件

Question

In the samples provided with CUDA 6.0, I'm running the following compile command with error output:

foo@foo:/usr/local/cuda-6.0/samples/0_Simple/cdpSimpleQuicksort$ nvcc --cubin -I../../common/inc cdpSimpleQuicksort.cu
nvcc warning : The 'compute_10' and 'sm_10' architectures are deprecated, and may be removed in a future release.
cdpSimpleQuicksort.cu(105): error: calling a __global__ function("cdp_simple_quicksort") from a __global__ function("cdp_simple_quicksort") is only allowed on the compute_35 architecture or above

cdpSimpleQuicksort.cu(114): error: calling a __global__ function("cdp_simple_quicksort") from a __global__ function("cdp_simple_quicksort") is only allowed on the compute_35 architecture or above

2 errors detected in the compilation of "/tmp/tmpxft_0000241a_00000000-6_cdpSimpleQuicksort.cpp1.ii".

I then altered the command to this, with a new failure:

foo@foo:/usr/local/cuda-6.0/samples/0_Simple/cdpSimpleQuicksort$ nvcc --cubin -I../../common/inc -gencode arch=compute_35,code=sm_35 cdpSimpleQuicksort.cu
cdpSimpleQuicksort.cu(105): error: kernel launch from __device__ or __global__ functions requires separate compilation mode

cdpSimpleQuicksort.cu(114): error: kernel launch from __device__ or __global__ functions requires separate compilation mode

2 errors detected in the compilation of "/tmp/tmpxft_000024f3_00000000-6_cdpSimpleQuicksort.cpp1.ii".

Does this have anything to do with the fact that the machine I'm on is only Compute 2.1 capable and the build tools are blocking me? What's the resolution... I'm not finding anything in the documentation that is clearly handling this error.

I looked at this question, and that... a link to documentation is simply not helping. I need to know how I have to modify the compile command.

Answer 1

Look at the makefile that comes with that cdpSimpleQuicksort project. It shows some additional switches that are needed to compile it, due to CUDA dynamic parallelism (which is essentially the second set of errors you are seeing.) Go back and study that makefile, and see if you can figure out how to combine some of the compile commands there with --cubin .

The readers digest version is that this should compile without error:

nvcc --cubin -rdc=true -I../../common/inc -arch=sm_35 cdpSimpleQuicksort.cu

Having said all that, you should be able to compile for whatever kind of target you want, but you won't be able to run a cdp code on a cc2.1 architecture.
