Cliff Click @ VMSS16: Bits of Advice For the VM Writer

I strongly recommend following and listening to videos by Cliff Click who wrote HotSpot and worked on Azul and other VMs. Cliff also has Coffee Compiler Club sessions on Fridays. - link - ▶ this video

I'm also a fan of Cliff and other Rice alumni; here are a few of his videos that I like. [0] The Sea of Nodes and the HotSpot JIT [1] A JVM Does That? [2] A Crash Course in Modern Hardware [3] Bits of Advice for the VM Writer [0] link [1] link [2] link [3] ▶ this video

I highly recommend folks to view this talk by the venerable Cliff Click called "Bits of Advice For the VM Writer" [1] Of particular interest are Continuation Style Passing Interpreters [2] and how much of a speedup you can get by going to raw assembly. The talk has lessons Cliff learned from his years on the JVM but those can be adapted easily to other runtimes. [1] ▶ this video [2] link

Thank you for the video, very interesting. The time for what you mentioned is here: ▶ this video (from 18:24 to 24:00)

He doesn't give a lot of details, but somewhere in the first 20 minutes of this talk (probably 15 minutes in), Cliff Click says that Hotspot had to create fair locks in user-space because kernel provided locks weren't adequate. ▶ this video

Very poor, there's no mention of continuation style passing interpreters. If anyone's curious about tales from the battlefield, highly recommend Cliff Click's talks (any of them) [1] [1] ▶ this video
