1 Purpose

e05jac is used to initialize communication data for the suite of multi-level coordinate search functions: e05jbc, e05jcc, e05jdc, e05jec, e05jfc, e05jgc, e05jhc, e05jkc and e05jlc.

2 Specification

#include <nag.h>
void  e05jac (Integer n_r, Nag_E05State *state, NagError *fail)
The function may be called by the names: e05jac or nag_glopt_bnd_mcs_init.

3 Description

e05jac initializes the structure state for the solver e05jbc and the optional-argument handlers e05jcc, e05jdc, e05jec, e05jfc, e05jgc, e05jhc, e05jkc and e05jlc.

4 References

None.

5 Arguments

1: n_r Integer
This argument is no longer accessed by e05jac.
2: state Nag_E05State * Communication Structure
state contains information required by other functions in this suite. You must not modify it directly in any way.
3: fail NagError * Input/Output
The NAG error argument (see Section 7 in the Introduction to the NAG Library CL Interface).

7 Accuracy

Not applicable.

8 Parallelism and Performance

e05jac is threaded by NAG for parallel execution in multithreaded implementations of the NAG Library.
Please consult the X06 Chapter Introduction for information on how to control and interrogate the OpenMP environment used within this function. Please also consult the Users' Note for your implementation for any additional implementation-specific information.

9 Further Comments

The time taken by e05jac is negligible.
