Elegant users forum

Hi all,

I am trying to run an optimization in Pelegant. I use the command,
It works fine as long as my method is 'simplex'. If I change it to anything else, I get an error,
Where OptimizedQ.bun is the bunch file written by my elegant code. I think all the parallel processes try to access the same bunch file and clashes. Is there any other changes I need to make in existing namelists other than in &parallel_optimization_setup for parallel optimization to work?

Thanks
Neeraj

Neeraj,

Can you post your .ele file?

Please find it attached.

Neeraj,

I'm not sure why that file-lock problem occurs, but you can solve it by removing the "bunch = %s.bun" statement from the &bunched_beam command; you don't really need it. Also, set one_random_bunch=1 to avoid confusing the optimizer.

Since you are doing tracking-based optimization, there's no benefit to using parallel_optimization_setup. You are better off using optimization_setup, so that elegant will track in parallel and optimize at the serial level.
