如何使用管道修改下述代码使其不会报deadlock？

Question

package main

import (
    "fmt"
)

func InitNum(ch chan int) {
    for i := 1; i <= 2000; i++ {
        ch <- i
    }
    close(ch)
}
func readNum(ch chan int, reschan chan map[int]int, remap chan bool) {
    for {
        temp, ok := <-ch
        if !ok {
            break
        } else {
            res := 0
            remp1 := make(map[int]int)
            for i := 1; i <= temp; i++ {
                res = res + i
            }
            remp1[temp] = res
            reschan <- remp1
        }
    }

}
func readMap(reschan chan map[int]int, remap chan bool) {
    for {
        temp, ok := <-reschan
        if !ok {
            fmt.Println("readMap break")
            break
        } else {
            fmt.Println(temp)

        }

    }
    remap <- true
    close(remap)

}
func main() {
    ch := make(chan int, 2000)
    reschan := make(chan map[int]int, 2000)
    remap := make(chan bool, 8)

    for i := 0; i < 8; i++ {
        go readNum(ch, reschan, remap)
        go readMap(reschan, remap)
    }
    go InitNum(ch)

    for i := 0; i < 8; i++ {
        <-remap
    }
}
