如何用gnuplot计算正实数的平方根？
我在debian下使用八度。一切正常。
我希望八度程序能够更快地完成。我的“CPU 使用监视器”图标 (LXDE) 显示，在计算倍频程时，只使用了大约三分之一的 CPU。
有没有办法将系统配置为使用更多 CPU 进行倍频程计算？
-- 更新 --
额外信息：查看htop我的程序运行时，我有以下内容：
- CPU 有 4 个内核和 7.71GiB RAM。
- 从开始到绘图之前，一个核心（显然是随机选择的）以 100% 使用，其他核心低于 2%。
- 绘图开始后，另一个核心（显然也是随机选择的，有时相同）用于 100%，其他核心保持在 2% 以下。
- MEM 使用量略有变化（最大差异 ~0.1GiB）。
- 交换没有变化。
对于几个应用程序，我得到了一个“空间不足”的错误，我希望解决这个错误。
示例（我的 debian 是德语）：
$ chromium
[2595:2595:0805/143635.823734:ERROR:process_singleton_posix.cc(280)]
Failed to create /home/jk/.config/chromium/SingletonLock:
Auf dem Gerät ist kein Speicherplatz mehr verfügbar (28)
[2595:2595:0805/143635.823938:ERROR:chrome_browser_main.cc(1410)]
Failed to create a ProcessSingleton for your profile directory.
This means that running multiple instances would start multiple browser
processes rather than opening a new window in the existing process.
Aborting now to avoid profile corruption.

我跑了，但使用 th函数htop找不到任何东西。chromF3
另外，我有这个空闲空间：
