使用 TBB 插入到无序升压双映射中

问：

我对 .我正在尝试在无序的 bimap 中插入 pair，其中 is of type 和 is type .我尝试创建 ，它在文件中，看起来像TBB<key, value>keyuint64_tvaluestringloop objectTBB.h

void ParallelIndex(uint64_t &kmer_len, std::string &split_kmer, std::string &sequence_content,
            uint64_t &sequence_length, size_t &kmer_position ) {
        parallel_for( blocked_range<size_t>(0, sequence_length),
                [&](const blocked_range<size_t>& r) {
            for(i = r.begin(); i < r.end();  ++i ){
                split_kmer = sequence_content.substr(i, kmer_len);
                reference_index_vector.insert(position(kmer_position, split_kmer)); 
                i += kmer_len-1;
                kmer_position += kmer_len;

                }
        }
        );
    }

在函数中，我尝试调用该函数mainTBB.cpp

index.ParallelIndex(index.kmer_len, index.split_kmer, index.sequence_content,
        index.sequence_length, index.kmer_position );

它从 0 开始，一直到 n。我试图增加 5（首先和 ，就像直到 n），但只增加了 1。i++ii +=kmer_len-1i = 0, 5, 10, 15, ...i

完整代码如下所示：

TBB.cpp

#include <iostream>
#include <string>
#include <algorithm>
#include <boost/bimap.hpp>
#include <boost/bimap/unordered_set_of.hpp>
#include <boost/bimap/unordered_multiset_of.hpp>
#include "tbb/parallel_for.h"
#include "TBB.h"
#include "tbb/tbb.h"
#include <tbb/blocked_range.h>



using namespace tbb;


namespace bimaps = boost::bimaps;
typedef boost::bimap<bimaps::unordered_set_of<uint64_t>,
        bimaps::unordered_multiset_of<std::string> > bimap_reference;
typedef bimap_reference::value_type position;
bimap_reference reference_index_vector;



uint64_t thread_test::create_index::kmer_len = 5;
std::string thread_test::create_index::split_kmer = "";
std::string thread_test::create_index::sequence_content = "ABCDDBACDDDCBBAAACBDAADCBDAAADCBDADADACBDDCBBBCDCBCDAADCBBCDAAAD";
uint64_t thread_test::create_index::sequence_length = 0;
size_t thread_test::create_index::kmer_position = 0;
size_t thread_test::create_index::i = 0;
int main(){
    thread_test::create_index index;
    index.sequence_length = index.sequence_content.length();

    index.ParallelIndex(index.kmer_len, index.split_kmer, index.sequence_content,
            index.sequence_length, index.kmer_position );

    for( bimap_reference::const_iterator iter = reference_index_vector.begin(), iend = reference_index_vector.end();
                iter != iend; ++iter ) {
            std::cout << iter->left << " <--> "<< iter->right <<std::endl;
        }

}

问题增加了 1，但我尝试如上所述将其增加 5。i
