我正在编写 C++ 和 GoLang 之间的性能比较以获取数据以执行统计分析,并且我创建了一个 Python 脚本来获取所有数据并自行执行这两个程序。使用 C++ 我没有问题并且执行工作正常,但是在 go 中我得到了这个错误:
panic: runtime error: index out of range
goroutine 1 [running]:
runtime.panic(0x44d600, 0x4b9897)
/usr/lib/go/src/pkg/runtime/panic.c:266 +0xb6
main.merge(0xc210047000, 0x9, 0x10, 0x8, 0x8, ...)
/windows/DATA/FIB/PE/B7_PLSpeed/nlogn.go:13 +0x22c
main.mergesort(0xc210047000, 0x9, 0x10, 0x8, 0x9)
/windows/DATA/FIB/PE/B7_PLSpeed/nlogn.go:43 +0xec
main.mergesort(0xc210047000, 0x9, 0x10, 0x5, 0x9)
/windows/DATA/FIB/PE/B7_PLSpeed/nlogn.go:42 +0xac
main.mergesort(0xc210047000, 0x9, 0x10, 0x0, 0x9)
/windows/DATA/FIB/PE/B7_PLSpeed/nlogn.go:42 +0xac
main.main()
/windows/DATA/FIB/PE/B7_PLSpeed/nlogn.go:54 +0x1c1
如果有人可以帮助我,我会非常高兴!我将在这里留下我的 Python 脚本和 Go 源代码。
Python:
import time
import random
from subprocess import call
from sys import argv
def usage():
print("Usage: " + argv[0] + " <Binary1> <Binary2> <n elements> <#executions>")
if __name__ == '__main__':
if len(argv) != 5:
usage()
else:
program1 = argv[1]
program2 = argv[2]
n = int(argv[3])
executions = int(argv[4])
for x in range(0, executions):
command = ['']
# 32-bit range vector(n) random generator
for y in range(0, n-1):
command.append(str(random.randint(-2147473648, 2147473647)))
if(random.choice((True, False))):
program1, program2 = program2, program1
# Program1
command[0] = './' + program1
pre = time.time()
call(command)
post = time.time()
f = open(program1 + ' - ' + str(n), 'a')
f.write(str(post-pre) + "ms\n")
f.close
# Program2
command[0] = './' + program2
pre = time.time()
call(command)
post = time.time()
f = open(program2 + ' - ' + str(n), 'a')
f.write(str(post-pre) + "ms\n")
f.close
