Hi I'm Praveen
Velliengiri, student from India. I'm working on developing a
Speculative compilation support in LLVM ORC JIT
Infrastructure. As LLVM ORC
supports compiling in multiple backend threads, it would be
effective if we compile the functions speculatively before
they are called by the executing function. So when we request
JIT to compile a function, JIT will immediately returns the
function address for raw executable bits. This will greatly
reduce the JIT latencies in modern multi-core machines. And
also I'm working on designing a ORC in-place dynamic profiling
support, by this JIT will automatically able to identify the
hot functions, and compile it in higher optimization level to
achieve good performance. I'm proposing this project for GSoC 2019. It would be helpful to know how this new features are effective to pgsql engine, so that I include your comments in "View from Clients" proposal section. Please reply :) Have a great day! PreeJackie |
