V_SQRT - A Library Routine for Computing Square Roots of Double-Precision Vectors on CRAY MPP <author> <version> <abstract> Computing square-roots have a substantially high result latency on the Cray MPP. We have implemented an efficient software routine on Cray MPP to compute the square-roots of a double-precision real vector. This program written in CAM assembler language runs about seven times faster than the currently available library routine. The worst case deviation of the computed values using v_sqrt from those computed using the standard library routine is about one least significant bit. <description><url>http://sdcd.gsfc.nasa.gov/ESS/exchange/contrib/udaya/v_sqrt.html</url> <reference><url></url> <contact>Udaya A.
