Copying large files over multi-gigabit networks

  • Optimize network settings:
    • Change maximum UDP buffer size (read and write) on sender and receiver: edit /proc/sys/net/core/rmem_max and /proc/sys/net/core/wmem_max. The number in the files determines the buffer size in bytes. We suggest the size to be 16MB (=16777216 bytes) for each of the buffers, which is the maximum allowed size.
  • The following commands are called from the directory udt3.3/app/
  • Run the sender: 
 ./sendfile
  • Run the receiver: 
 Syntax: 
 ./recvfile <IP address/hostname of sender> <port number> <remote source file name> <local destination file name>
 Example: 
 ./recvfile 127.0.0.1 9000 /home/jschulze/data/largefile.tif ./temp.tif
