示例1: partition_data
// Create a partition which acts as a proxy to a part of the embedded array.
// The proxy is assumed to refer to either the left or the right boundary
// element.
partition_data(partition_data const& base, std::size_t min_index)
: data_(base.data_.data()+min_index, 1, buffer_type::reference),
size_(base.size()),
min_index_(min_index)
{
HPX_ASSERT(min_index < base.size());
}示例2: partition_data
// Create a partition which acts as a proxy to a part of the embedded array.
// The proxy is assumed to refer to either the left or the right boundary
// element.
partition_data(partition_data const& base, std::size_t min_index)
: data_(base.data_.data()+min_index, 1, buffer_type::reference,
hold_reference(base.data_)), // keep referenced partition alive
size_(base.size()),
min_index_(min_index)
{
HPX_ASSERT(min_index < base.size());
}示例3: heat_part
// The partitioned operator, it invokes the heat operator above on all
// elements of a partition.
