FYI, Yesterday's Slashdot had an article about Linux compiler benchmarks from Coyote Gulch (Scott Ladd). In this update he compares GCC and ICC. You can read the article here: http://www.coyotegulch.com/reviews/linux_compilers/ Of particular note was his use of SciMark 2.0 which is a NIST developed benchmark for scientific computing. Its available in both java and C and computes a MFLOPS number. It would be good to include this in our test suite if we can (hint, hint, John). You can find it...

...way that it finds a consistent workload to execute. I know its early in LLVM's life for something like this, but I thought I'd mention it so it can be tucked away in the "think about this later" file.

Has anyone tried acovea on llvm, acovea is a fairly popular software package that uses GAs(Genetic Algorithms) to tune compiler command-line settings to optimize the performance for a given application. It works with gcc for sure.

Is acovea still being distributed? The link that I was able to find (http://www.coyotegulch.com/products/acovea/) is no longer valid. -Hal On Thu, 2012-01-05 at 12:06 -0500, Xin Tong wrote: > Has anyone tried acovea on llvm, acovea is a fairly popular software > package that uses GAs(Genetic Algorithms) to tune compiler > command-line settings to optimize the performance for...

I think it is still be hosted on some bzr servers. Thanks Xin On Thu, Jan 5, 2012 at 12:20 PM, Hal Finkel <hfinkel at anl.gov> wrote: > Is acovea still being distributed?

Dear R Users, I compiled two R-1.9.1 environments on IBM P690 AIX platform, one with optimization level 3(-O3), another with optimization level 2(-O). I would like to do some performance comparison with these two environments. Can anybody give me some advices for how to do the performance test against R? Thanks in advance. Kexiao
