Hi. I would like to run a mixed effects model, but there's one aspect of the model that I don't know how to code. My goal is to analyze data from an experiment in which I tested the swimming performance (i.e., Umax) of two species of fish from 4 different lakes (a sample of the data is below). Each fish was tested when it was rested and when it was tired, and each test was

Hi All, I'm using R1.8.1 on Windows XP. I'm having trouble producing an R library from source code. A colleague has written the source code, in Unix. I've copied the source code across to Windows (with the help files, data files, description and index) and am trying to compile it into a library. I've "sourced" each of the *.r files and they appear to work.

Very nice! A 14% speedup on a benchmark we don't tune for isn't bad. I imagine that there are several easy wins you could get on it if you were interested

Hi R, Please solve my problem........... I am extracting Bloomberg data from R, in a loop. R is getting fatigued by doing this process and gives some errors. I introduced sleep function. Doing this sometimes I get the results and sometimes not. I even noticed that if I give complete rest for R (don't open R window) for 1 day and then run my code with the sleep function, then the program works. But if I ke...

Duncan, With the commit from http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121203/158488.html, the Polyhedron 2005 benchmarks complete again on x86_64-apple-darwin12. The result are similar to what were seen with FSF gcc 4.6.2svn and llvm/dragonegg 3.0 (which was the last release that passed pb05) http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-October/044091.html.

[CCing Dale since this was his change, not mine] The change in 81455 fixes a compiler crash. It doesn't happen very often, but I can't imagine we would want to back that out. Fixing it would be a more reasonable solution. From a quick look at it, the problem is that gcc/config/darwin-c.c is registering va_opt for GC. When you build for Fortran, darwin-c.o is not linked so the GC gets

Hi Jack, thanks for these numbers. > With the commit from http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121203/158488.html, > the Polyhedron 2005 benchmarks complete again on x86_64-apple-darwin12.

Hi Jack, thanks for the numbers. Any chance of analysing why gcc does better on those where it does much better than dragonegg?

Below are the results for the Polyhedron 2005 benchmarks compiled with llvm/compiler-rt/dragonegg 3.3svn at r182439 against current FSF gcc 4.7.3svn and 4.8.1svn. The only major bug remaining in the dragonegg 3.3svn support for gcc 4.8.x is http://llvm.org/bugs/show_bug.cgi?id=15980 which results in unresolved symbols for _iround and _iroundf in the aermod and rnflow testcases. Note that this

Is anyone able to bootstrap llvm-gcc42 svn on x86_64-apple-darwin10? Currently it is failing here with... /sw/src/fink.build/llvm-gcc42-2.9-0/llvm_gcc42_objdir/./prev-gcc/xgcc -B/sw/src/fink.build/llvm-gcc42-2.9-0/llvm_gcc42_objdir/./prev-gcc/ -B/sw/lib/llvm-gcc-4.2/x86_64-apple-darwin10/bin/ -c -g -O2 -mdynamic-no-pic -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes

Attached are the Polyhedron 2005 benchmark results for current llvm/dragonegg svn on x86_64-apple-darwin11 built against Xcode 4.3.2 and FSF gcc 4.6.3. The benchmarks for -msse3 and -msse4 appear identical (at least for degg+optnz). This is fortunate since there seems to be a bug in -msse4 on 2.33 GHz (T7600) Intel Core 2 Duo Merom (http://llvm.org/bugs/show_bug.cgi?id=12434).

How does this compare to LLVM 3.0 - were there any regressions? Ciao, Duncan. The benchmarks > for -msse3 and -msse4 appear identical (at least for degg+optnz). This is fortunate > since
