[atlas-devel] Compiling ATLAS for simulated environments

[Stéphane Z. <szu...@ud...>]

Greetings,

I am running experiments on an x86 simulator. It can be configured to be 
cycle-accurate, but in general I'd like to delay using the accurate 
timing system until I have "serious" measurements to make (read: until I 
am ready to pay for the slowness of executions).

Here's my question: since I know all the timings for caches (Frequency, 
L1D, L1I, L2, TLBs etc., which I can configure as I want), is there a 
way to let ATLAS know about all this to significantly reduce the search 
space (along with execution times)? I looked at the manual which told me 
how to specify the L2 size, but I saw nothing for L1 data caches.

Hopefully, someone will be able to help me with this!
Thanks,

Stéphane
