Scheduled Transfer is a mechanism to bypass operating-system latency associated with setting up buffers in a receiving system by pre-allocating buffer space - scheduling a transfer. Support for a variety of operating systems is available, and mover platforms (see above) for each are now available at Oak Ridge. Probe equipment will be used to do performance testing of this protocol.

(May 2001) Further investigation has shown spotty support for ST in operating systems other than IRIX and a very steep learning curve. This project will be pursued only at low priority.

(January 2002) Further research has shown that the benefits achievable with Scheduled Transfer do not greatly exceed the benefits we see from Gigabit Ethernet jumbo frames. That fact, together with the inappropriateness of Wide-Area implementation of ST (no error correction), the lack of any implementation on any operating system except linux and IRIX and the considerable effort required to develop and maintain such a capability, have led us to decide that ST is not worth further attention.
