This version of the Worder Node is targeted to setup x86_64 machines in "compatibility" mode, i.e.
both 32bit and 64bit libraries are provided. The YAIM tool configures the LD_LIBRARY_PATH variable
accordingly. The command to install the Worker Node is yum groupinstall as follows:
yum groupinstall glite-WN
In order to get both 32bit and 64bit libraries, both versions of certain rpms must be installed.
On a x86_64 machine yum resp. rpm usually installs the 64bit rpm over the 32bit package but
for certain rpms this seems not to be the case (for yet unknown reasons). It has been observed
that the following binaries are 32bit on the x86_64 Worker Node:
/opt/lcg/bin/gfal_*
/opt/lcg/bin/lcg-*
/opt/lcg/bin/lfc-*
/opt/glite/bin/glite-delegation-*
/opt/glite/bin/glite-srm-*
/opt/glite/bin/glite_data_catalog_*
/opt/glite/bin/glite-transfer-*
However, this should not be a problem as 32bit binaries can be executed on a x86_64 machine.
This issue will be dealt with in future releases.
IMPORTANT: Sites using the tarball distribution must make sure that they have
the openldap-clients rpm installed.
