Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hama Wiki" for change notification.

The following page has been changed by udanax:

New page:
ScaLAPACK (Scalable LAPACK) is a linear algebra library for parallel computers. Routines are
available to diagonalize or solve dense and narrow band systems of linear equations. 

ScaLAPACK implements block-oriented LAPACK linear algebra routines, adding a special set of
communication routines to copy blocks of data between processors as required. Similar to LAPACK,
a single subroutine call typically carries out the necessary computations. 

ScaLAPACK installations include the following libraries: scalapack, redist, pblas, tools,
blacs, blacsCinit, and blacsF77init.

== An meeting with Professor Choi J. which a member of ScaLAPACK ==

 * What is the Block-Oriented?
 * Why use shared memory instead of files?
 * Are there any ways (or methods) to handle to files?
 * What are the relative merits and demerits of the ScaLAPACK?
 * Performance Results?

And, In the last question

 * What do you think about the Hama approaches?
