Hi,

I also need information about the command line option for making a spot
request persistent. I am currently using:

starcluster start -o -b mybid mycluster

and in the AWS online GUI console, I see that this generates a one-time
spot request not a persistent one. I googled on AWS or starcluster to find
out how to change this after request or when I make the initial request,

thank you very much for your support,

Kind Regards,
