c - Get the Apple llvm clang compiler with MP and MPI support -


i have compile program (gromacs 4.6) on mac mpi , mp support , cuda. cuda 8.0 (required) not allow use of gcc on mac, "apple llvm 8.0.0".

i tried hard set clang compiler support openmp , openmpi not working.

what managed getting llvm 4.0.0 installed openmp , openmpi support, compiling nvcc complaining: 

nvcc fatal   : version ('40000') of host compiler ('clang') not supported

is there way got apple llvm openmp support?

edit:

$ clang-4.0 -fopenmp hello_openmp.c   # works fine 
$ gcc -fopenmp hello_openmp.c clang: error: unsupported option '-fopenmp' 
$ gcc --version configured with: --prefix=/library/developer/commandlinetools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 apple llvm version 8.0.0 (clang-800.0.42.1) target: x86_64-apple-darwin16.7.0 thread model: posix installeddir: /library/developer/commandlinetools/usr/bin 
$ clang-4.0 --version clang version 4.0.1 (tags/release_401/final) target: x86_64-apple-darwin16.7.0 thread model: posix installeddir: /usr/local/opt/llvm/bin

file hello_openmp.c:

#include <omp.h> #include <stdio.h> int main()  {     #pragma omp parallel     printf("hello thread %d, nthreads %d\n", omp_get_thread_num(), omp_get_num_threads()); }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
