similar to: Testing Performance of R on AIX

Hi Uwe Liqqes, Does the successful compilation for R-1.9.1 on AIX 5.1 depend on the IBM AIX compiler for C and C++ (xlc/xlC)? gcc on AIX is not compatible with R1.9.1.

Hi your guys, Recently, I installed R-1.9.1 on AIX 5.2 with 64 bits environment; I already have following software installed on AIX before I compile R-1.9.1 source codes: g++ 2.9.aix51.020209-4 The GNU C++ compiler and headers gcc 2.9.aix51.020209-4 The GNU gcc C compiler and headers xlf XL Fortran for AIX perl 5.6.1-2 zlib 1.1.3-10 For latex and makeinfo stuffs, I have

Dear R Development Team, Does the latest version R-1.9.1 provide parallel functions if R is running on Multiple CPUs Unix platform (IBM AIX e-server)? Kexiao [[alternative HTML version deleted]]

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.

I'm cross-posting the message below (from GCC list) because I believe it would (at some point) be very beneficial to build an evolutionary optimization pass into LLVM. The idea would be to discover the perfect set of optimizations for a given program by trying them all and analyzing the execution times of each. This would be somewhat like profile driven optimization except the profile is

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?

This is a hot topic in the compiler research community, but the focus there is on (a) choosing the right optimization sequences internally and transparently, rather than through combinations of options, (b) performance prediction techniques so you don't actually have to run gazillion different choices, and perhaps can even avoid the problem of choosing representative inputs, as you talked

Hi Paul, I use executable codes of tex and latex from http://aixpdslib.seas.ucla.edu/packages/tetex.html) and compile the original R-1.9.1 source codes using C for AIX compiler V6.0 and Fortran for AIX compiler 7.1.1 and generate 64 bit R environments. It works well. Kexiao -----Original Message----- From: Paul Murrell [mailto:p.murrell at auckland.ac.nz] Sent: Monday, August 02, 2004 6:10

Dear R Development Team, I compile R-1.9.1 on AIX 5.2 under 2.9-aix51-020209, and xlf 7.1. In order to let R compile successfully under gcc 2.9, I have to change one C statement of file(RHOME//src/modules/X11/devX11.c) line 1768 from "retrun FALSE" to "retrun NULL", following is C code snapshot: newX11Desc * Rf_allocNewX11DeviceDesc(double ps) { newX11Desc *xd;

sshd disconnects openssh-4.1p1 on IBM p690 AIX 5200-05 using: openssl-0.9.7g zlib-1.2.2 openssh-4.1p1 CC="gcc -O0 -maix64" ./configure #- 64-Bit !!! Compiles ok. ssh works fine. sshd starts, accepts password, user authenticated and then disconnects. Debug log of both sshd and trying-to-connect client (3.9p1-3.2 on Linux) are enclosed. For test purposes por 3333

Dear R Development Team, I just compile R-1.9.1 on AIX 5.2 using gcc 2.9-aix51-020209. During the compile process, there is an error message saying "return type mismatch in R_HOME/src/modules/X11/devX11.c line 1768. Following is the part of the C codes from file devX11.c /** This allocates an newX11Desc instance and sets its default values. */ newX11Desc *

Hi folks, I've got a problem with X11 forwarding on an AIX 5.2 system thats stumped me. I've installed the same patched + compiled installp package on all our aix boxes but one of them won't play ball with X11 ssh -X -v -v user at host gives (grepped out X11 looking lines) debug2: we sent a password packet, wait for reply debug1: Authentication succeeded (password). debug1:

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

I tried to install the latest version of R (2-1.0)in anAIX machine. I was able to tar, and configure with no errors. However, when I said make, I got the following errors: gcc -Wl,-bM:SRE -Wl,-H512 -Wl,-T512 -Wl,-bnoentry -Wl,-bexpall -Wl,-bI:../../../etc/R.exp -L/usr/local/lib -o R_X11.so dataentry.lo devX11.lo rotated.lo rbitmap.lo -lSM -lICE -lX11 ld: 0711-317 ERROR: Undefined symbol:
