+## Multiple SGAs with same instalation directory
+
+Multiple SGAs can be run from the same installation directory. In this case, we 
+have a installation directory shared among all SGA machines via NFS. 
+All SGAs machines share the same script sgad.sh and configuration file sgad.cfg. 
+To run multiple SGAs in this environment, the following changes can be done:
+
+sgad.sh
+```bash

+export SGAD_HOST=$HOSTNAME
