Intel LLVM Optimizer Optimization Flags

Robert_M_3 — Tue, 24 Feb 2015 15:21:25 GMT

Hi all,

I'm using the Intel offline compiler and the LLVM-based optimizer with Intel specific optimizations (oclopt). For the optimizer I have used regular O optimization levels (O1, O2, O3) which included many optimization in two passes. As there are plenty of individual optimizations available, I'm interested to know which optimization flags have potentially big impact on performance.

Can you please suggest me some optimizations?

Best regards,
Robert

Hi Robert,

oclopt is a utility used for internal purposes: you may use it at your own risk. See Yuri Kulakov's reply in this thread: https://software.intel.com/en-us/forums/topic/539655
