Optimize shared libraries with PGO or AutoFDO?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have a very large application similar to SciPy. There are many shared libraries loaded dynamically. I’d like to use PGO/AutoFDO to optimize the compilation of these libraries. Is this possible? 

I repeatedly run simulations that take hundreds of cpu hours. It would be worth the effort to squeeze 10% more performance from these libraries for this particular task. Statically compiling everything is not likely, sadly. 

Thanks.
