Since my name was dropped in an earlier post by Dirk (and to prevent the conversation from becoming a general discussion on what is nice about Mac OS X and what isn't), I'll post the benchmarks I sent to Dirk here, too.
I benchmarked the computation times for my function sparseLTS() from package robustHD for different problem sizes on my laptop running Linux: 100 observations, 1000 variables: With Arma: user system elapsed 10.312 0.004 10.332 With Eigen: user system elapsed 6.525 0.000 6.534 100 observations, 10 000 variables: With Arma: user system elapsed 269.889 2.148 272.606 With Eigen: user system elapsed 214.134 2.320 216.904 If people are interested, I post the code for the benchmarks later on (I don't have them on the machine that I'm currently working on). As far as I remember the speed gain with Eigen is much larger on Linux than on Windows, so I can also run the code on my Windows machine. - Andreas On Mon, May 7, 2012 at 7:43 AM, Tim Triche, Jr. <[email protected]> wrote: > Why Mac OS X? > > 1) it's shiny > 2) it's Unix > 3) everything's a PDF > > Two of my most competent coworkers absolutely love their Macs.
