.SH "DESCRIPTION"
.PP 
CSDP is a library of routines that implements a predictor corrector variant of
the semidefinite programming algorithm of Helmberg, Rendl, Vanderbei, and
Wolkowicz.  The main advantages of this code are that it is written to be used
as a callable subroutine, it is written in C for efficiency, the code runs in
parallel on shared memory multi\-processor systems, and it makes effective use
of sparsity in the constraint matrices.
.PP 
The csdp binary is a simple command\-line interface to the library.

.SH "EXIT STATUS"
.PP 
The output is a solution, together with some timing information.
The exit status indicates the following:
.IP 0
A solution to the problem was found.
.IP 1
The problem is primal infeasible.
.IP 2
The problem is dual infeasible.
.IP 3
The problem was solved with reduced accuracy.
.IP 4
The maximum number of iterations was reached without finding a solution.
.IP 5
The search got stuck at the edge of primal feasibility.
.IP 6
The search got stuck at the edge of dual feasibility.
.IP 7
Lack of progress in finding a solution was detected.
.IP 8
The system matrix is singular, factorization of the matrix failed, or solving
for dy or dy1 failed.
.IP 9
Too many line search failures were encountered.
.IP 10
An input problem or solution could not be read.
.IP 12
The gap became infinite or NaN.
