Hi Johnathan, Thanks for the reply. I'm using Ubuntu 14.04 on a Dell XPS laptop with 8 cores. Results of the grep call are below:
model name : Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz model name : Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz model name : Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz model name : Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz model name : Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz model name : Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz model name : Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz model name : Intel(R) Core(TM) i7-2630QM CPU @ 2.00GHz I noticed that there are 12 other uses of a_avx in volk_config. Is it likely that using any of the kernels with a_avx will cause a similar issue? -Mike On Fri, Oct 31, 2014 at 2:19 PM, Johnathan Corgan <[email protected]> wrote: > On 10/30/2014 02:07 PM, Michael Rahaim wrote: > > > While I'm happy to have it working again, I don't exactly know what this > > modification actually does.
