Hello
I'd like to use R in a Ubuntu cluster so I have installed R and Rmpi in
a clean Ubuntu Lucid installation. Reading about Rmpi I need to have R
and Rmpi installed in all nodes in the cluster. I have tried to export R
executable and /usr/lib/R to the other nodes. When I try to run R in
node2 I get the following error
meteo at boira2:/boira/R$ ./R
./R: line 208: /usr/lib/R/etc/ldpaths: No such file or directory
/usr/lib/R/bin/exec/R: error while loading shared libraries: libR.so: cannot open shared object file: No such file or directory
Then, after exporting /etc/R I get a the same error with libblas.so.3gf
not found
What should be better? to install R and Rmpi in every node or to export
R and all dependencies from the master node to the rest of nodes in the
cluster? I'd prefer to keep R installed just in the master node so any
packages update or config changes are not to be repeated in the other
nodes (just 2, not a big deal but...)
Thanks in advance.
