I'm a CPU and memory eating monster🦕

Developer will encounter the need to quickly occupy CPU and memory, I am also deeply troubled, so I developed a tool named eat to help you quickly occupy a specified amount of CPU and memory.

Todo

• Support eat -c 35% and eat -m 35%
• support gracefully exit: capture process signal SIGINT(2), SIGTERM(15)
• support deadline: -t specify the duration of eat progress. such as "300ms", "1.5h", "2h45m". (unit: "ns", "us" (or "µs"), "ms", "s", "m", "h")
• CPU Affinity
• Memory read/write periodically , prevent memory from being swapped out
• Dynamic adjustment of CPU and memory usage
• Eat GPU

Usage

eat -c 4            # eating 4 CPU core
eat -c 35%          # eating 35% CPU core (CPU count * 35%)
eat -c 100%         # eating all CPU core
eat -m 4g           # eating 4GB memory
eat -m 20m          # eating 20MB memory
eat -m 35%          # eating 35% memory (total memory * 35%)
eat -m 100%         # eating all memory
eat -c 2.5 -m 1.5g  # eating 2.5 CPU core and 1.5GB memory
eat -c 3 -m 200m    # eating 3 CPU core and 200MB memory
eat -c 100% -m 100% # eating all CPU core and memory
eat -c 100% -t 1h # eating all CPU core and quit after 1hour

Tips:

• Using <Ctrl> + C to stop eating and release CPU and memory

Build

go build -o eat

介绍

我是一个吃CPU和内存的怪兽🦕

开发者们经常会遇到需要快速占用 CPU 和内存的需求，我也是。所以我开发了一个名为 eat 的小工具来快速占用指定数量的 CPU 和内存。

待办

• 支持eat -c 35%和eat -m 35%
• 支持优雅退出: 捕捉进程 SIGINT, SIGTERM 信号实现有序退出
• 支持时限: -t 限制吃资源的时间，示例 "300ms", "1.5h", "2h45m". (单位: "ns", "us" (or "µs"), "ms", "s", "m", "h")
• CPU亲和性
• 定期内存读写，防止内存被交换出去
• 动态调整CPU和内存使用
• 吃GPU

使用

eat -c 4            # 占用4个CPU核
eat -c 35%          # 占用35%CPU核（CPU核数 * 35%）
eat -c 100%         # 占用所有CPU核
eat -m 4g           # 占用4GB内存
eat -m 20m          # 占用20MB内存
eat -m 35%          # 占用35%内存（总内存 * 35%）
eat -m 100%         # 占用所有内存
eat -c 2.5 -m 1.5g  # 占用2.5个CPU核和1.5GB内存
eat -c 3 -m 200m    # 占用3个CPU核和200MB内存
eat -c 100% -m 100% # 占用所有CPU核和内存
eat -c 100% -t 1h   # 占用所有CPU核并在一小时后退出

提示：

• 使用<Ctrl> + C来停止占用并释放CPU和内存

构建

go build -o eat
