Following is the list of fp benchmarks that fail. They all pass with -O3, but some fail with -O4. I did the test run. Thanks, Reza Estimated Estimated Base Base Base Peak Peak Peak Benchmarks Ref. Run Time Ratio Ref. Run Time Ratio -------------- ------ --------- ---------

Hi, We are currently working on revising a journal article that describes our work on pre-allocation scheduling using LLVM and have some questions about LLVM's pre-allocation scheduler. The answers to these question will help us better document and analyze the results of our benchmark tests that compare our algorithm with LLVM's pre-allocation scheduling algorithm. First, here is a

433.milc, 447.deall, and 450.soplex are run as part of the nightly tests on Darwin (=MacOSX) in a way that closely approximates -O4. They are working there. I am inclined to suspect gold given that they work at -O3. Can a Linux person comment? On Jul 23, 2010, at 10:19 AMPDT, Reza Yazdani wrote: > Following is the list of fp benchmarks that fail.

Hello, I down loaded "llvm-gcc4.2-2.7-x86_64-linux" and I built Spec2006 with it. It is great and except for one benchmark the rest work fine. I want to build them with LTO now. I followed the directions in " http://llvm.org/docs/GoldPlugin.html" and built ar, nm-new, and ld-new in binutils. I also built libLLVMgold.so. I get the following error: llvm-gcc: -use-gold-plugin,

Hi, What are the best options to compile Spec2006 with LLVM compilers to get the best performance numbers on x86? Has anybody compared LLVM Spec2006 numbers with GCC 4.5 base? reza -------------- next part -------------- An HTML attachment was scrubbed...

Hi Reza, -O4 is the highest level of LLVM optimization that I know of. But, I don't know if it has been tried on Spec2006. IIRC, Dan Gohman has run Spec. tests with LLVM, so he can provide more info. - fariborz On Jul 19, 2010, at 6:06 PM, Reza Yazdani wrote: > Hi, > > What are the best options to compile Spec2006 with LLVM compilers to > get the best performance numbers

I've searched the Web with Google and do not find what might cause this particular error from an invocation of cenboxplot: cenboxplot(cu.t$quant, cu.t$ceneq1, cu.t$era, range=1.5, main='Total Recoverable Copper', ylab='Concentration (mg/L)', xlab='Time Period') Error in if (n > 0) (1L:n - a)/(n + 1 - 2 * a) else numeric() : argument is of length zero I do

Hi, We are using LLVM 2.9 (with the llvm-gcc front end) to compile and run the SPEC CPU2006 benchmarks on x86. We are compiling and running the benchmarks on a an Intel Xeon E5540 processor running Ubuntu 10.10 (64-bit version). For the native x86-64 target, we are using the following command-line arguments: -O3 -march=core2 -mtune=core2 and are getting compile-time errors on the gamess and

I'll address two issues. The first is today's error message and the other is change management for contributed packages on CRAN. TODAY'S ERROR MESSAGE I switched from the 0.995-1 versions of lme4 and Matrix to those referenced in the subject line this afternoon. Prior to using these packages on anything else, I applied them to code that 'worked' (provided numerical results

Dear all, I am using the bigglm package to fit a few GLM's to a large dataset (3 million rows, 6 columns). While trying to fit a Poisson GLM I noticed that the coefficient estimates were very different from what I obtained when estimating the model on a smaller dataset using glm(), I wrote a very basic toy example to compare the results of bigglm() against a glm() call. Consider the

Dear all i?m working with a program i?ve made in R (using functions that others created) to run my program i need a sample. if i generate the sample using for example, rnorm(n, mu, sigma) i have no problem but if i obtain a sample from a column in excel and i copy it, the program says that there is a mistake: it says "Error en `[.data.frame`(data, indices) : undefined columns

Hi everyone, I have a problem with running a glm using a subset of my data. Whenever I choose a subset, in the summary the factors arent shown (as if the variable was a continuous variable). If I dont use subsets then all the factors are shown. I have copied the output from summary for both cases. Thanks for the help, Muri > model<-glm(log(cpue)~year,family=gaussian) Call: glm(formula =
