Parallel Matrix Transpose Routines <author> <version> <abstract> Code performs a global transpose on a matrix P which is domain decomposed along rows. Each node packs (subroutine 'pack') its columns of P into N_nodes 2-D buffers and performs a matrix transpose on each one (subroutine 'internal_transpose'). Each transposed buffer is then sent to its corresponding node (subroutine 'global_transpose'). Finally, each node unpacks (subroutine 'unpack') the N_nodes buffers it receives, one from each node, and loads them into a 2D array. This array contains each node's columns of the transposed P matrix. <description> <url>http://sdcd.gsfc.nasa.gov/ESS/exchange/contrib/rood/parallel_transpose.html </url> <reference><url></url> <contact> <keywords>parallel processing; matrix transpose (GAMS D1b3); numerical routine <category>numerical-linalg <publication-date> <environment> <method> <application> <comments> </urc>
