Current Status (1/2)

Current Status (2/2)

• MPI_Send Sending the message
• Start_tcp_send
• User_data
• Send the Header (globus_io_write)
• Insert message compression method
• Globus_io_register_write gt Write_callback
• Need to more implementation
• Extension of RSL (Resource Specification
  Language)
• Type of application and Location information
• Support the NWS (Network Bandwidth)

4
Buffing and Fragmentation

• Point-to-Point communication
• Buffering (Ring)
• Have not issue
• Not Enough effect
• Fragmentation
• Already support TCP/IP layer in the router
• Issue
• Overlap communication and computation
• Support of MPI in runtime

5
Application-aware process selection (1/2)

• Profiling Information
• Recognize the characteristics of MPI application
• MPI functions such as MPI_Send, MPI_Recv etc
• Relation of the topology
• Calculate the communication size and frequency
  between processes
• The status of processes
• Manage the processes
• Replace the process in the runtime for more
  efficiency performance

6
Application-aware process selection (2/2)

• Replace the new process

Future work

• Full implementation of the ASIC
• Survey the application-aware process selection or
  other idea
