Start with the gRPC installation directory and define some environmental variables
export GRPC_INSTALL_DIR=/daqfs/gRPC/installation
export GRPC_JAVA_INSTALL_DIR=/daqfs/gRPC/java_installation
export PATH="$GRPC_INSTALL_DIR/bin:$PATH"
export LD_LIBRARY_PATH="$GRPC_INSTALL_DIR/lib:$LD_LIBRARY_PATH"


Running the ET related programs


Access to ET system files has been made simple by placing them into the gRPC installation
ET libraries are in $GRPC_INSTALL_DIR/lib
ET includes are in $GRPC_INSTALL_DIR/include
ET executables are in $GRPC_INSTALL_DIR/bin
ET jar file is in $GRPC_JAVA_INSTALL_DIR/jars


Run the ET system as a fifo. Use 1000, 150kB buffers
cd $GRPC_INSTALL_DIR/bin
./et_start_fifo -f /tmp/fifoEt -d -s 150000 -n 1 -e 1000
On the same node, run a java-based consumer of ET system buffers with a delay of 1 microsec between fifo gets (ERSAP simulator)
java -cp $GRPC_JAVA_INSTALL_DIR/jars/*  org.jlab.coda.et.apps.ErsapFifoConsumer -f /tmp/fifoEt -v -d 1


Running the ejfat repository's gRPC enabled programs


Compile the code in the ersap branch of the ejfat repository'
cd <ejfat dir>/build
git pull
rm CMakeCache.txt
cmake .. -DBUILD_ET=1 -DBUILD_GRPC=1
make
Run the simulated control plane
cd $GRPC_INSTALL_DIR/bin
./control_plane -a 127.0.0.1 -p 50051


Run the data reassembler
--reassembler
Run the data sender
--sender
