Vector runahead delivers extremely high memory-level parallelism even for the chains of dependent memory accesses with complex intermediate address computation, which conventional techniques fundamentally cannot handle and, therefore, have ignored. It does this by rearchitecting to use speculative data-level parallelism, rather than work skipping, as its primary form extracting more in mode a t...

Partial control-flow linearization is a code transformation conceived to maximize work performed in vectorized programs. In this article, we find new service for it. We show that partial protects programs against timing attacks. This sound: Given an instance of its public inputs, the partially linearized program always runs same sequence instructions, regardless secret inputs. Incidentally, if ...

abstract present study used translog cost function for determining break point of paddy farms. requested data set include inputs’ prices and quantities, and production amounts had been acquired from 500 rice farmers of guilan province at 2009. model used in this study is seemingly unrelated regressions (sur). the results showed that labor and pesticides had the highest and lowest share of produ...
