示例1: main

parse_arg(arg, argc, argv);
std::cout << "[INFO ] Creating column ..." << std::endl;
Column* column = new Column(arg.coltype, arg.nbits, arg.size);
std::cout << "[INFO ] Creating bit vector ..." << std::endl;
BitVector* bitvector = new BitVector(column);
std::cout << "[INFO ] Populating column with random values ..." << std::endl;
auto dice = std::bind(std::uniform_int_distribution<WordUnit>(
std::numeric_limits<WordUnit>::min(),

WordUnit mask = (1ULL << arg.nbits) - 1;
for(size_t i=0; i < arg.size; i++){
column->SetTuple(i, dice() & mask);
}
std::cout << "[INFO ] omp_max_threads = " << omp_get_max_threads() << std::endl;
