Exemplos comuns de operações limitadas por CPU são coisas que exigem processamento matemático complexo.

Por exemplo:

* **Processamento de áudio** ou **imagem**

			// callhome running on a different node.
			// sleep for some time and try again.
			duration := max(time.Duration(r.Float64()*float64(globalCallhomeConfig.FrequencyDur())),
				// Make sure to sleep at least a second to avoid high CPU ticks.
				time.Second)
			time.Sleep(duration)
		}
	}()
}

func runCallhome(ctx context.Context, objAPI ObjectLayer) bool {
	// Make sure only 1 callhome is running on the cluster.

        assertThrows(IllegalArgumentException.class, () -> cli.calculateDegreeOfConcurrency("XXXC"));

        int cpus = Runtime.getRuntime().availableProcessors();
        assertEquals((int) (cpus * 2.2), cli.calculateDegreeOfConcurrency("2.2C"));
        assertEquals(1, cli.calculateDegreeOfConcurrency("0.0001C"));

	}
	return formattedName
}

var (
	// https://github.com/golang/lint/blob/master/lint.go#L770
	commonInitialisms         = []string{"API", "ASCII", "CPU", "CSS", "DNS", "EOF", "GUID", "HTML", "HTTP", "HTTPS", "ID", "IP", "JSON", "LHS", "QPS", "RAM", "RHS", "RPC", "SLA", "SMTP", "SSH", "TLS", "TTL", "UID", "UI", "UUID", "URI", "URL", "UTF8", "VM", "XML", "XSRF", "XSS"}

	}
	info := getLocalServerProperty(globalEndpoints, &r, metrics)
	return madminServerProperties.NewJSONWith(&info), nil
}

// GetCPUsHandler - returns CPU info.
func (s *peerRESTServer) GetCPUsHandler(_ *grid.MSS) (*grid.JSON[madmin.CPUs], *grid.RemoteErr) {
	info := madmin.GetCPUs(context.Background(), globalLocalNodeName)
	return madminCPUs.NewJSONWith(&info), nil
}

		if n := runtime.NumGoroutine(); n > 10000 && !globalIsCICD {
			return nil, fmt.Errorf("unable to perform CPU IO profile with %d goroutines", n)
		}
		dirPath, err := os.MkdirTemp("", "profile")
		if err != nil {
			return nil, err
		}
		fn := filepath.Join(dirPath, "cpuio.out")
		f, err := Create(fn)
		if err != nil {
			return nil, err
		}
		stop := fgprof.Start(f, fgprof.FormatPprof)

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**.

	return resp.ValueOrZero(), err
}

// GetCPUs - fetch CPU information for a remote node.
func (client *peerRESTClient) GetCPUs(ctx context.Context) (info madmin.CPUs, err error) {
	resp, err := getCPUsHandler.Call(ctx, client.gridConn(), grid.NewMSS())
	return resp.ValueOrZero(), err
}

### 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 \
    include/tensorflow/c/eager/dlpack.h \
