c++ - Hello World CUDA compilation issues -

-

i'm using cuda example book , attempting compile first real example in book. i'm on osx 10.9.2:

my source is:

@punk ~/documents/projects/cuda$ /developer/nvidia/cuda-6.0/bin/nvcc hello.c nvcc warning : 'compute_10' , 'sm_10' architectures deprecated, , may removed in future release. hello.c:6:1: error: unknown type name '__global__' __global__ void kernel(void) { ^ hello.c:6:12: error: expected identifier or '(' __global__ void kernel(void) {            ^ hello.c:10:3: error: use of undeclared identifier 'kernel'   kernel<<<1,1>>>();   ^ hello.c:10:11: error: expected expression   kernel<<<1,1>>>();           ^ hello.c:10:17: error: expected expression   kernel<<<1,1>>>();                 ^ hello.c:10:19: error: expected expression   kernel<<<1,1>>>();                   ^ 6 errors generated.

and source simply:

punk ~/documents/projects/cuda$ cat hello.c  #include <cuda.h> #include <stddef.h> #include <stdio.h> //#include "common/book.h"  __global__ void kernel(void) { }  int main(void) {   kernel<<<1,1>>>();    printf("oh hai\n");   return 0; }

i tested /developer/nvidia/cuda-6.0/samples/1_utilities/devicequery example , built , ran fine.

any appreciated! tia!

rename file hello.cu

nvcc by default sends .c or .cpp files directly host compiler without doing device code inspection or compilation on them.

there various options change behavior.

php - render data via PDO::FETCH_FUNC vs loop -

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
