### Running a TensorFlow server

TensorFlow is a platform for distributed computing, and as such there is a
TensorFlow server (`tf.train.Server`). The TensorFlow server is intended for

   * segments, each governed by its own write lock. The segment lock is taken once for each explicit
   * write, and twice for each cache loading computation (once prior to loading the new value, and
   * once after loading completes). Much internal cache management is performed at the segment
   * granularity. For example, access queues and write queues are kept per segment when they are

package cmd

import (
	"os"
)

var (
	// No special option for reads on windows
	readMode = os.O_RDONLY

	// Write with sync no buffering only used only for `xl.meta` writes
	writeMode = os.O_SYNC
