Hello Egor, Since we get Intel software partnership, we can request an access to the performance lab at Intel in Nizhny. They provide a computer, software and a specialist for a week.
We may ask Vadim Sukhomlinov if any possibilities exist to optimize code from Moscow. Thanks. And btw, yes. I have an account on Alexey's home server. ;-) On Tue, May 19, 2009 at 9:31 PM, Egor Pasko <[email protected]> wrote: > On the 0x5AF day of Apache Harmony [email protected] wrote: >> Hi all, >> >> I'm interested in compiler optimizations and have some thoughts on >> improving the IR and optimizations of Jitrino.OPT.
