- Note that we now need version 2.3.1 of PSBLAS.
To compile:
TO COMPILE
0. Unpack the tar file in a directory of your choice (preferrably
outside the main PSBLAS directory).
1. run configure --with-psblas=<ABSOLUTE path of the PSBLAS install directory>
adding the options for SuperLU, SuperLU_Dist, UMFPACK as desired.
See MLD2P4 User's and Reference Guide (Section 3) for details.
2. Tweak Make.inc if you are not satisfied.
3. make;
4. Go into the test subdirectory and build the examples of your choice.
Notes:
NOTES
- The single precision version is supported only by SuperLU; thus, even
if you specify at configure to use UMFPACK or SuperLU_Dist, the
