Java语言怎么编写一个加速软件，去提高CBU的运算速度

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class CBUAcceleration {
    private static final int THREAD_POOL_SIZE = Runtime.getRuntime().availableProcessors();

    public static void main(String[] args) {
        int[] input = {1, 2, 3, 4, 5};
        int result = calculateCBU(input);
        System.out.println("Result: " + result);
    }

    private static int calculateCBU(int[] input) {
        ExecutorService executor = Executors.newFixedThreadPool(THREAD_POOL_SIZE);
        int result = 0;

        // 分割任务，每个线程计算部分结果
        for (int i = 0; i < THREAD_POOL_SIZE; i++) {
            final int startIndex = i * (input.length / THREAD_POOL_SIZE);
            final int endIndex = (i + 1) * (input.length / THREAD_POOL_SIZE);
            executor.execute(new CBUWorker(input, startIndex, endIndex));
        }

        executor.shutdown();

        // 等待所有线程结束
        while (!executor.isTerminated()) {
            Thread.yield();
        }

        return result;
    }

    private static class CBUWorker implements Runnable {
        private final int[] input;
        private final int startIndex;
        private final int endIndex;

        public CBUWorker(int[] input, int startIndex, int endIndex) {
            this.input = input;
            this.startIndex = startIndex;
            this.endIndex = endIndex;
        }

        @Override
        public void run() {
            int result = 0;

            // 计算部分结果
            for (int i = startIndex; i < endIndex; i++) {
                // 运算逻辑
                result += input[i];
            }

            // 合并结果（例如累加）
            synchronized (CBUWorker.class) {
                // 计算任务之间的数据合并
            }
        }
    }
}
