我已经阅读了有关如何运行N个Tornado进程的各种文章和教程,其中N =核心数.我的代码正在运行,在所有16个核心上运行,但我设法搞砸了它,我需要新的眼睛.

import tornado.ioloop
import tornado.web
import tornado.httpserver

from core import settings
from core import coreService
import services

from tornado.options import define, options, parse_command_line

define("port", default=settings.SERVER_PORT, help="run on the given port", type=int)



app = tornado.web.Application([
    (r'/upload', coreService.Upload)
])

if __name__ == "__main__":
    tornado.options.parse_command_line()
    server = tornado.httpserver.HTTPServer(app, max_buffer_size=1024*1024*201)
    server.bind(options.port)
    # autodetect cpu cores and fork one process per core
    server.start(0)
    try:        
        print 'running on port %s' % options.port
        tornado.ioloop.IOLoop.instance().start()

    except KeyboardInterrupt:
        tornado.ioloop.IOLoop.instance().stop()

此代码抛出此错误:

File "/opt/tornado/tornado/process.py", line 112, in fork_processes
    raise RuntimeError("Cannot …
