C#写一个进程把所有cpu核心占满

临时用于鲲鹏920 docker环境下的cpu速度：

using System;
using System.Diagnostics;
using System.Numerics;
using System.Reflection;
using System.Threading.Tasks;

class Program
{
    static void Main()
    {
        // 创建80个任务
        var tasks = Enumerable.Range(0, 80)
            .Select(index => Task.Run(() => { RunProcess(index); }))
            .ToList();

        // 等待所有任务完成
        Task.WhenAll(tasks).Wait();
    }

    private static void RunProcess(object index)
    {
        var stopwatch = new Stopwatch();
        stopwatch.Start();
        BigInteger sum = 0;
        while (stopwatch.ElapsedMilliseconds < 10000)
        {
            Random random = new Random();
            BigInteger a = BigInteger.Pow(2, random.Next(1,32));
            BigInteger b = BigInteger.Pow(2, random.Next(1, 32));
            sum += 1*a * b/a*b;

        }

        Console.WriteLine($"Process {index} completed. sum:{sum}");
    }
}
