我有一个关于openmp编译的问题.
如下代码:
#include <iostream>
#include <pthread.h>
#include <omp.h>
#include <semaphore.h>
#include <stack>
using namespace std;
sem_t empty,full;
stack<int> stk;
void produce(int i)
{
{
sem_wait(&empty);
cout<<"produce "<<i*i<<endl;
stk.push(i*i);
sem_post(&full);
}
}
void consume1(int &x)
{
sem_wait(&full);
int data=stk.top();
stk.pop();
x=data;
sem_post(&empty);
}
void consume2()
{
sem_wait(&full);
int data=stk.top();
stk.pop();
cout<<"consume2 "<<data<<endl;
sem_post(&empty);
}
int main()
{
sem_init(&empty,0,1);
sem_init(&full,0,0);
pthread_t t1,t2,t3;
omp_set_num_threads(3);
int TID=0;
#pragma omp parallel private(TID)
{
TID=omp_get_thread_num();
if(TID==0)
{
cout<<"There are "<<omp_get_num_threads()<<" threads"<<endl;
for(int i=0;i<5;i++)
produce(i);
}
else …当我想同时使用推力和c ++时,我遇到了关于编译的大问题.
这是项目结构(只是一个测试项目):
sortbase.h
#include<iostream>
#include <thrust/device_vector.h>
using namespace std;
template<class T>
class SortBase
{
public:
void Init()
{
}
void resize(const int &x)
{
CV.resize(x);
cout<<"resize succeed!"<<endl;
}
private:
thrust::device_vector<T> CV;
};
sorter.h
#ifndef __SORTER_H__
#define __SORTER_H__
#include <iostream>
#include <thrust/device_vector.h>
#include "sortbase.h"
using namespace std;
template<class T>
void ttest()
{cout<<"tttttttttttttttt";cout<<endl;}
template<class KEY>
class Sorter
{
public:
Sorter():CV(NULL)
{
CV=new SortBase<KEY>();
}
~Sorter()
{
if (CV!=NULL)
{
delete CV;
CV=NULL;
}
}
__host__ __device__
virtual bool operator()(const KEY& x,const …
