I've attempted to use the optimized GotoBLAS2 library with a freshly compiled R-2.11.1 patched on 64-bit Ubuntu 10.4. (See details below). When I run this version of R, the timings are not different than the original install, and only one core is used in test computations.
Can someone point out my error? Thanks. --Dale Details ... I'm running the 64-bit version of Ubuntu 10.04 on my 2 core laptop. I first installed needed tools as follows: sudo apt-get build-dep r-base sudo apt-get install gobjc sun-java6-jdk sun-java6-jre Subsequently, I successfully installed R 2.11.1 patched from subversion using defaults: ./configure Next, I built the optimized Optimized GotoBLAS2 libraries version 1.13 and placed the file 'libgoto2_penrynp-r1.13.so' in /usr/lib Finally, I renamed the original 'libRblas.so' file that was installed in /usr/local/lib64 and created a soft link to the libgoto2 file. cd /usr/local/lib64/R/lib sudo ln -s /usr/lib/libgoto2_penrynp-r1.13.so libRblas.so _______________________________________________ R-SIG-Debian mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-debian
