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"
- 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 to:
- send data to the backend
- reassemble backend data and send info to control plane
- simulate the control plane
- 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 data reassembler with PID loop and communication back to control plane
cd <ejfat dir>/build/bin ./packetBlasteeEtFifo -p 17750 -b 4000000 -r 25000000 -cores 82 -f /tmp/fifoEt
- Run the data sender
cd <ejfat dir>/build/bin ./clasBlaster -f /daqfs/java/clas_005038.1231.hipo -host 172.19.22.244 -p 19522 -mtu 9000 -s 25000000 -cores 80
- Run the simulated control plane
cd <ejfat dir>/build/bin ./control_plane -a 127.0.0.1 -p 50051
