**Subject: Nonlinear Matrix Equation**

Dear NA readers,

Consider the following matrix equations

M X \Lambda^2 + D X \Lambda + K X = 0 (1)

X_0^H (X-X_0) = 0 (2)

where M,D,K are $n \times n$ real matrices.

X denotes a m-dimensional complex subspace

\Lambda is a square complex matrix of order m<<n.

One way to solve these equations for X, \Lambda is to apply the

vec-operator to (1), (2) followed by Newton's method.

However, this approach becomes inefficient in case of large problems.

Any pointer on this problem would be appreciated.

**Subject: INCITE 2005 Call for Proposals**

The National Energy Research Scientific Computing (NERSC) Center at the

U.S. Department of Energy's Lawrence Berkeley National Laboratory

solicits proposals for large allocations of computing resources. The

Innovative and Novel Computational Impact on Theory and Experiment

(INCITE) program will award a total of 5.5 million processor hours and

100 terabytes of mass storage on the systems described at

<http://www.nersc.gov/>. The program seeks computationally intensive

research projects of large scale, with no requirement of current

Department of Energy sponsorship, that can make high-impact scientific

advances through the use of a large allocation of computer time and data

storage at the NERSC facility. A small number of large awards is

anticipated.

Successful proposals will describe high-impact scientific research in

terms suitable for peer review in the area of research and also

appropriate for general scientific review comparing them with proposals

in other disciplines. Applicants must also present evidence that they

can make effective use of a major fraction of the 6,656 processors of

the main high performance computing facility at NERSC. Applicant codes

must be demonstrably ready to run in a massively parallel manner on that

computer (the IBM SP, Seaborg).

Eligibility: Principal investigators engaged in scientific research with

the intent to publish results in the open peer-reviewed literature are

eligible. This program specifically encourages proposals from

universities, other research institutions and industry. Industry is

specifically solicited to propose challenging problems that may be

solved using high performance computing research. There is no

requirement of current sponsorship by the Office of Science of the

Department of Energy, which sponsors the NERSC Center.

Application Process: Applications will be accepted only electronically,

following instructions found at

<http://www.nersc.gov/projects/incite/incitecall.php>. Proposals will be

accepted until midnight PDT Wednesday, September 8, 2004. Awards are

expected to be announced by November 8, 2004, and access to the NERSC

facilities for the awardees will be established on December 1, 2004, and

remain in effect until November 30, 2005. Questions about the

application procedure should be directed to <incite-info@nersc.gov>.
