Description

Pcard-73145

  • 问题背景:
    在以下case argsort会导致hang住:
import numpy import paddle input_tensor = (numpy.random.random([2, 1140850690]) - 0.5).astype("float16") paddle_x = paddle.to_tensor(numpy_tensor) paddle_out = paddle.argsort(paddle_x) 
constexpr int64_t max_elements = 1 << 30; const int64_t segment_size = num_cols; const int64_t element_per_call = std::min(max_elements, total_elements); const int64_t batch_size = (element_per_call / segment_size) * segment_size; 

在被sort的维度大于2^30时,(element_per_call / segment_size)为0,导致死循环
