Question

当我使用PyOpenCL运行内核＆＃34; SIMPLE_JOIN＆＃34;它失败了。

.CL文件中的内容的标题

void SIMPLE_JOIN(__global const int* a, int a_col, __global const int* a_valuesPic,
                 __global const int* b, int b_col, __global const int* b_valuesPic,
                __global const int* join_valuesPic, __global int* current, const int maxVars, __global int* buffer, int joinVar)

PyOpenCL中的执行

program.SIMPLE_JOIN(context, (a_col, b_col), None,  \
                    buffer_a, np.int32(a_col), buffer_a_valPic, \
                    buffer_b, np.int32(b_col), buffer_b_valPic, \
                    buffer_join_valPic, buffer_current, np.int32(maxVars), \
                    buffer_result, np.int32(joinList[0]))

命令行中的错误

内核调用的第一个参数应该是命令队列，而不是上下文：

program.SIMPLE_JOIN(的 queue , (a_col, b_col), None, \...

PyOpenCL |无法启动内核
