[R] Connecting to "heterogenous" cluster using makeSOCKcluster of SNOW-package
When trying to create (a very simple) cluster using makeSOCKcluster or makeCluster I get the following error message:> library(snow) > cl <- makeSOCKcluster("localhost")Fatal error: kann Datei '~/R/i686-suse-linux-gnu-library/2.8/snow/RSOCKnode.R' nicht ?ffnen: Datei oder Verzeichnis nicht gefunden (translation: could not open file [...]: File or directory not found) The R-prompt does not re-appear until CTRL-C has been pressed. RSCOKnode.R is definitely there with all access right: ls -l ~/R/i686-suse-linux-gnu-library/2.8/snow/RSOCKnode.R -rwxrwxrwx 1 GEOECOLOGY\francke GEOECOLOGY\mitarbeiter 911 7. Apr 14:51 /home/GEOECOLOGY/francke/R/i686-suse-linux-gnu-library/2.8/snow/RSOCKnode.R In contrast, creating explicitly "homogenous" cluster works:> setDefaultClusterOptions(homogeneous = TRUE) > cl <- makeSOCKcluster("localhost")Since I intend to use really "inhomgenous" clusters, I followed the respective instructions given on http://www.stat.uiowa.edu/~luke/R/cluster/cluster.html#Section:InhomogeneousSystems. I also tried the modifications to RSOCKnode.sh proposed in http://heather.cs.ucdavis.edu/~matloff/R/RProg.pdf - no different behaviour. I'd appreciate any comments that help me in getting an incomogenous cluster running without the need of MPI or PVM. Thanks in advance. Till Francke Dept. for Geoecology University of Potsdam --
