Installing PLAPACK R1.1 and the PLAPACK R1.1 Linear Solver Package

Installing PLAPACK R1.1 and the
PLAPACK R1.1 Linear Solver Package

1. Get the library
ftp://ftp.cs.utexas.edu/pub/plapack/R1.1/
The binaries each correspond to a given platform. As an example, we will assume you download plapackR11.sp2.tar.Z, the IBM SP2 version.
2. Get the solver release :
ftp://ftp.cs.utexas.edu/pub/plapack/SOLVERS/R1.1/solversR11.tar.Z
3. Prepare the library
- a. cd to the directory in which you want the PLAPACK directory to reside,
  and move the plapackR11.sp2.tar.Z file to the current directory.
- b. execute the command
  
  % zcat plapackR11.sp2.tar.Z | tar xvf -
  
  This creates a PLAPACK directory and fills it up with some files.
- c. edit the file PLAPACK/Make.include
  You only need to set the variable PLAPACK_ROOT (at the top of Make.include.)
  Set PLAPACK_ROOT to the full path name of your PLAPACK directory.
4. Prepare the solver package.
- a. Move the file solversR11.tar.Z to your PLAPACK directory.
- b. Untar it:
  
  % zcat solversR11.tar.Z | tar xvf -
  
  This creates a SOLVERS directory inside your PLAPACK directory, and fills it with files.
5. Build the solver package and sample driver
% cd SOLVERS
% make
% cd EXAMPLES
% make
6. Run the sample driver
(for IBM SP2)
% LU_driver.x -procs 4

(for Cray T3E)
% mpprun -n 4 LU_driver.x

(for General MPI machine)
% mpirun -np 4 LU_driver.x
