Abstract—Let $A$ be a sorted array of $n$ numbers and $B$ a sorted array of $m$ numbers, both in nondecreasing order, with $n \leq m$. We consider the problem of determining, for each element $A\left(j\right)$, $j$$=$$1$, $2$, $\cdots,$$n$, the unique element $B\left(i\right)$, $0 \leq i \leq m$, such that $B\left(i\right)$$\leq A\left(j\right)$$< B\left(i+1\right)$ (with $B\left(0\right) = - \infty$ and $B\left(m+1\right) = +\infty$). We present an efficient parallel algorithm for solving this problem in $O\left(\log m\right)$ time using $O\left\left(\left\{\left\{n\;\left\{\rm log\right\}\left(m/n\right)\right\}\over\left\{\left\{\rm log\right\}\; m\right\}\right\}\right\right)$ EREW PRAM processors. Our algorithm improves the previously known results on either the time or processor complexity, and enables us to solve several other problems optimally on the EREW PRAM.
