+## 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
+#!/bin/bash
+export CSBASE_SERVER="http://localhost:40409"
+export SGAD_HOST=$HOSTNAME
+export SGAD_PORT=40100
+export SGAD_NAME=$HOSTNAME
+export SGAD_PLATFORM="Linux44_64"
+export SERVER_DATA_DIR="/mnt/csgrid_data"
+
+timestamp=$(date +%Y%m%d%H%M%S)
