Can AVX instruction be executed in parallel


Can two avx instrcutions can be executed in parallel?

For example,


            a1= _mm256_load_ps((Rin +offset)); 
            a2= _mm256_load_ps((Gin +offset));  
            a3= _mm256_load_ps((Bin +offset));

            ac0 = _mm256_mul_ps(a1, in2outAvx_11); 
            ac1 = _mm256_mul_ps(a2, in2outAvx_12);
            ac2 = _mm256_mul_ps(a3, in2outAvx_13);
            z0 = _mm256_add_ps(ac0,ac1);
            z1 = _mm256_add_ps(z0, ac2);

pin-2.14-71313 and WinSock library

I have a problem trying to start my pintool built with WinSock library (ws2_32.lib) - it immediately exits with message "Failure to open DLL file WS2_32.dll".
I've prepared a simple pintool to illistrate the problem:

#include "pin.H"

namespace WINDOWS
#include <Ws2tcpip.h>
void *p = WSAStartup;

int main(int argc, char *argv[])
if (PIN_Init(argc, argv)) return 1;
return 0;
