ILUPACK – Numerical solution of large sparse linear systems Ax=b
Numerical solution of large sparse linear systems Ax=b by
iterative methods, in particular preconditioned Krylov subspace methods
preconditioner constructed from incomplete LU decomposition
PRECONDITIONED KRYLOV SUBSPACE METHODS
General case. As iterative solver preconditioned restarted GMRES is used.
Symmetric positive definite case. Use preconditioned CG.
INCOMPLETE LU DECOMPOSITION
Incomplete LU decomposition methods
WSMP Home Page – WSMP: Watson Sparse Matrix Package
Multithreaded performance has improved significantly in Version 10, especially for the symmetric solvers.Functions for transposing distributed matrices are now available.
The regular 64-bit libraries can now handle large matrices with factors containing more than 2 billion nonzeros without requiring an 8-byte integer library.
Two new massively parallel platforms, Blue Gene P and Cray XT4 are now supported.
New symmetric factorization algorithms have been introduced that reduce memory use in multithreaded mode.
Software available from alphaWorks for AIX, Linux, and SunOS.
If you need WSMP and PWSMP libraries for any other platform, please send e-mail to discuss the possibility.

DB2 ” Honza’s perspective
The whole problem is in the format of the passwords in /etc/shadow. DB2 doesn’t seem to like the passwords generated when changing password using the standard passwd command. In Fedora Core 10 the password is hashed using sha-512.
DB2 works fine with passwords hashed with standard crypt function. Password in the desired format can be obtained by calling openssl passwd desiredPassword. The output of openssl can be passed to usermod –password
