Question about how multicore processors work:
This is an AMD quad-core system. If, for example, I tell GIMP to perform
some complicated operation on a large image, 'top' and 'htop' show me
that one of the cores is running at 100% while the other cores are doing
almost nothing. I gather this isn't any faster than a single-core
processor running at the same speed would be. It would seem to me to get
the operation done more quickly if several cores were handling it.
So I guess my question is, why is GIMP only using one core? Does this
have anything to do with how GIMP is coded or compiled? Is there any
way to speed things up by making it use more than one core? Or is each
process only executed by one of the cores? Thanks in advance for any
enlightenment!
