问题
For my current project, I need to use CUDA and the Intel C/C++ compilers in the same project. (I rely on the SSYEV implementation of Intel's MKL, which takes roughly 10 times as long when using GCC+MKL instead of ICC+MKL (~3ms from GCC, ~300µs from ICC).
icc -v
icc version 12.1.5
NVIDIA states, that Intel ICC 12.1 is supported (http://docs.nvidia.com/cuda/cuda-samples/index.html#linux-platforms-supported), but even after having downgraded to Intel ICC 12.1.5 (installed as part of the Intel Composer XE 2011 SP1 Update 3), I am still running into this issue:
nvcc -ccbin=icc src/test.cu -o test
/usr/local/cuda-5.5/bin//..//include/host_config.h(72): catastrophic error: #error directive: -- unsupported ICC configuration! Only ICC 12.1 on Linux x86_64 is supported!
#error -- unsupported ICC configuration! Only ICC 12.1 on Linux x86_64 is supported!
Unfortunately, it seems as if Nvidia is merely tolerating the use of ICC, because I would hardly call it "support", given the lack of information provided by Nvidia for using ICC together with CUDA.
I am running Ubuntu 12.10 x86_64 and CUDA 5.5. Telling icc to mimick the behavior of the stock GCC 4.7.2 using the -Xcompiler -gcc-version=470 option did not help either. Using google/search, I was only able to find threads from the Nvidia forums dealing with CUDA 3.x and Intel ICC 11.1, but I was unable to transfer the obtained information to current CUDA releases.
I would be very grateful for any suggestion on how to solving this issue :-)
回答1:
Referring to the file referenced in the error you received, it's specifically looking for an ICC compiler with a particular build date:
#if defined(__ICC)
#if !(__INTEL_COMPILER == 9999 && __INTEL_COMPILER_BUILD_DATE == 20110811) || !defined(__GNUC__) || !defined(__LP64__)
#error -- unsupported ICC configuration! Only ICC 12.1 on Linux x86_64 is supported!
#endif
The solution would be to have the intel compiler that actually matches that specified build date. As indicated, ICC 12.1, ie. version 12.1.0.233, instead of ICC 12.1.5 should do the trick.
The narrow focus is at least partly due to a test limitation. In this case, a particular ICC variant was tested with the CUDA toolkit before it was released, and so that host config check has this test in it.

I confronted the problem when compiling madagascar-1.5 with icc2013 and ifort2013. Then I try to resolve the problem by downloading ICC version 2011 update7. Based the INTEL_COMPILER_BUILD_DATE which is 20110811, I can download the correct one. I think the date 20110811 matched icc is the correct one.
