Compiler errors Cuda向量类型的推力支持
我目前正在尝试使用推力：：上限函数。我在向函数提供参数时遇到了一个问题。我想使用CUDA向量类型，特别是Compiler errors Cuda向量类型的推力支持,compiler-errors,cuda,thrust,Compiler Errors,Cuda,Thrust,我目前正在尝试使用推力：：上限函数。我在向函数提供参数时遇到了一个问题。我想使用CUDA向量类型，特别是double3，但当我使用这种类型时，我会遇到几个推力库错误 我正在运行的代码块如下所示： /********************************************************************************

eos_search_gpu()
purpose --- kernel to find the upper bound index for the
interpolation values
arguments --
y --- input double3 values for which we are searching
my --- input int number of values for which we are searching
x --- input double3 array of structs containin the data table
values for x, y, and f corresponding to structs
".x", ".y", and ".z"
n --- input int number of data values in the table
dim_x --- input int number of data values in the x-direcion of table
j[] --- input/output int[] array of int'sthat contains
the index of the (x,y,f) position of the upper bound
library calls --
__host__ __device__ ForwardIterator thrust::upper_bound(
const thrust::detail::execution_policy_base<DerivedPolicy>& exec,
ForwardIterator first,
ForwardIterator last,
const LessThanComparable & value
)
exec --- the execution policy to use for parallelization
first --- the beginning of the ordered sequence
last --- the end of the ordered sequence
value --- the value to be searched.
Returns: the furthermost iterator i, such that value < *i is false
const detail::seq_t thrust::seq
an execution policy which requires analgorithm invocation to execute
sequentially in the current thread.
