XY模型计算报错

[IMPLICIT-NONE]

您好，在尝试使用您的软件计算 XY 模型的磁有序温度。下载了最新的安装包，使用 samples 中的 Square_XY_isotropic 进行测试，使用 4 核心计算时，输出正常，但是将核心数增大到 8 以后，计算报错。错误信息如下：

The above exception was the direct cause of the following exception:

其他信息：

1. 为了提高测试速度，将超胞大小降为了 16 16 1，thermalization 和 relaxiation 步数降为了 40000 和 80000。
2. 用了 anoconda3 部署环境

感谢您的耐心回复。

It is obvious that your machine does not have enough memory to support it.
