Abstract
Chaining is the ability to pipeline two or more vector instructions on Cray-1 like machines. The authors show how to optimally use this feature to compute (vector) expression trees in the context of automatic code generation. They present a linear time scheduling algorithm for finding an optimal order of evaluation for a machine with a bounded number of registers
