尝试 运行 NVIDIA FleX 时获得 "buffer overflow detected"
Getting "buffer overflow detected" when trying to run NVIDIA FleX
我使用 Singularity 2.6 有一段时间了，最近将我的 Singularity 升级到了 3.0（由于技术原因我无法升级到 3.0.3）。使用 Singularity 3.0，我使用与使用 Singularity 2.6 构建容器时完全相同的定义文件构建新容器。从那以后，我再也不能 reliably 运行 NVIDIA FleX 并且时不时地遇到以下错误。在过去 10 个月左右的时间里，我绝对没有更改我的 NVIDIA FleX 代码中的任何内容，而且我几乎每天都 运行 使用 FleX，从来没有遇到过这样的问题。我想知道可能是什么问题，试图说的错误是什么？我可能做错了什么或需要更改以防止这种情况发生？
根据我在代码中输入的打印语句，我所知道的是当我在 FleX 代码中调用 UnmapBuffers() 函数时会发生这种情况；但自从我编写这段代码以来，我一直在这样做，从来没有遇到过任何问题。虽然这可能不是很有帮助，但函数的作用如下：

对于那些 Singularity 用户：不幸的是，我无法再尝试使用 Singularity 2.6 来查看问题是否消失，因为我正在使用集群并且无法自己安装东西。
请注意，我在构建它时将 NVIDIA 的 Docker 图像拉入我的容器中。这是构建容器时我的 Singularity 定义文件的主要部分：
BootStrap: docker
From: nvidia/cuda:9.0-cudnn7-devel-ubuntu16.04

事实证明，我的代码在模拟期间试图在磁盘上创建一个文件，但由于某种原因无法创建该文件，这可能与 this 有关。该代码在过去始终有效，但我不知道我的容器中发生了什么变化导致该部分代码无法再创建该文件。
我使用 Singularity 2.6 有一段时间了，最近将我的 Singularity 升级到了 3.0（由于技术原因我无法升级到 3.0.3）。使用 Singularity 3.0，我使用与使用 Singularity 2.6 构建容器时完全相同的定义文件构建新容器。从那以后，我再也不能 reliably 运行 NVIDIA FleX 并且时不时地遇到以下错误。在过去 10 个月左右的时间里，我绝对没有更改我的 NVIDIA FleX 代码中的任何内容，而且我几乎每天都 运行 使用 FleX，从来没有遇到过这样的问题。我想知道可能是什么问题，试图说的错误是什么？我可能做错了什么或需要更改以防止这种情况发生？
根据我在代码中输入的打印语句，我所知道的是当我在 FleX 代码中调用 UnmapBuffers() 函数时会发生这种情况；但自从我编写这段代码以来，我一直在这样做，从来没有遇到过任何问题。虽然这可能不是很有帮助，但函数的作用如下：

对于那些 Singularity 用户：不幸的是，我无法再尝试使用 Singularity 2.6 来查看问题是否消失，因为我正在使用集群并且无法自己安装东西。
请注意，我在构建它时将 NVIDIA 的 Docker 图像拉入我的容器中。这是构建容器时我的 Singularity 定义文件的主要部分：

事实证明，我的代码在模拟期间试图在磁盘上创建一个文件，但由于某种原因无法创建该文件，这可能与 this 有关。该代码在过去始终有效，但我不知道我的容器中发生了什么变化导致该部分代码无法再创建该文件。
