[Help-gsl] Optimizing function for Vegas

[Tommy Nordgren]

I've got a 5-dimensional Vegas integration problem, that must be  
solved for a large
set of bound parameters.
The function I need to integrate is computed with the routines
gsl_integration_qawo    and    gsl_intgration_qawf

The problem I'm faced with is making the function called by vegas  
much faster,
since the current implementation requires 48 hours to complete for  
just 7
data sets.

The problem I'm trying to solve is a 6-dimensional integration over  
infinite space,
Where the function to be integrated contains a complex exponential  
factor of a
linear combination of some of the integration variables.
