Scalability is a double edged sword...Scalability is a double edged sword...Posted Jul 19, 2002 16:07 UTC (Fri) by DeletedUser2649 ((unknown), #2649)In reply to: Scalability is a double edged sword... by iabervon Parent article: Scalability is a double edged sword... I'm just a dabbler in this area; I've done a little bit of parallel computation, and a decent amount of study of it, both in classes and on my own. You sound experienced. I wanted to know what you think of McVoy's solution to this problem: minimise the number of spinlocks (perhaps keeping it optimised for a 4-processor SMP, since that's known to work reasonably well), and instead support SMP clusters. There's a brief article on the bad part of fine-grained locking at http://www.linuxmall.com/news/?1,43. I can't find Larry's article on the solution anymore; it's hard to find, but it's out there. Opinions? It sounds great to me: seems like the best of all worlds, with more capabilities for everyone. -Billy
