And as most of the execution time is taken by actual work (instead of waiting), and the work in a computer is done by a <abbr title="Central Processing Unit">CPU</abbr>, they call these problems "CPU bound".

---

Common examples of CPU bound operations are things that require complex math processing.

For example:

* **Audio** or **image processing**.

### 官方 Docker 镜像上的进程数

此镜像上的**进程数**是根据可用的 CPU **核心**自动计算的。

这意味着它将尝试尽可能多地**榨取**CPU 的**性能**。

你还可以使用 **环境变量** 等配置来调整它。

但这也意味着，由于进程数量取决于容器运行的 CPU，因此**消耗的内存量**也将取决于该数量。

因此，如果你的应用程序消耗大量内存（例如机器学习模型），并且你的服务器有很多 CPU 核心**但内存很少**，那么你的容器最终可能会尝试使用比实际情况更多的内存 可用，并且性能会下降很多（甚至崩溃）。 🚨

### 创建一个`Dockerfile`

以下是如何根据此镜像创建`Dockerfile`：

     third_party/xla/third_party/tsl/tsl/platform/ctstring_internal.h \
     ${LIB_PKG}/include/tsl/platform
  cd ${LIB_PKG}
  libtensorflow_zip="libtensorflow${TARBALL_SUFFIX}.zip"
  zip libtensorflow-cpu-windows-$(uname -m).zip \
    lib/tensorflow.dll \
    lib/tensorflow.lib \
    include/tensorflow/c/eager/c_api.h \
    include/tensorflow/c/eager/c_api_experimental.h \

of Go values and free that space manually all at once, safely. The purpose
of this functionality is to improve efficiency: manually freeing memory
before a garbage collection delays that cycle. Less frequent cycles means
the CPU cost of the garbage collector is incurred less frequently.

This functionality in this package is mostly captured in the Arena type.
Arenas allocate large chunks of memory for Go values, so they're likely to
