====== UDT - UDP-based Data Transfer ====== TCP often maxes out at slow speeds on a single connection of around 9MB/sec. UDT can transfer between campusrocks and soe at 160MB/sec. http://udt.sourceforge.net/ The default creates in udt4/app sendfile and recvfile utilities. For these to work you need to on both sending and receiving machines tell it where to find the .so library setenv LD_LIBRARY_PATH /thepath/udt4/src/ On the sending machine you type sendfile This opens up a connection and returns a port number. On the receiving machine type nslookup [send_machine_name] to get the ip address of the sending machine. Now that you have the port number (returned by sendfile) and the ip address of the sending machine given by nslookup, you can transfer the file using recvfile like this: recvfile [send_ip_address] [send_port_num] [full/path/to/file/on/send/machine] [./recieve_file_name]
