Detailed Description

Manage CPU/GPU logs and writing them to appropriate output.

Routines to coordinate three objects:

• host_log : log data structure on host memory
• device_log : log data structure on device memory.
• writer : provider class to write to desired output device

Purpose:

• Stream log messages from device_log to host_log to writer
• Allocating memory for device_log and host_log
• Select and configure plugin for writer
• Stream lprintf messages to standard output

There is a default instance of this class that is initialized in swarm::init. For the most part you do not need to instantiate this class as long as you only need one log stream for your application. After initializing the swarm package using swarm::init, you can get the dafult log manager by calling log::manager::default_log() This is a good replacement for global hlog and dlog variables that were used in old swarm.

Stream the log from host_log and device_log to the output.

Flush the output buffer for both host and device.

• Replay lprintf
• Download device_log to host_log
• Output host_log to writer
