- 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"
Rrunning 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
Now on to running the gRPC enabled programs
- 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
