Users should take care of multi-server configurations. +Creating a guided configuration file is based on an I/O trace file of a previous execution of the application. +For this the `trace_reads` tracing module is used (see above). -Finally, enable the distributor using the next compilation flags: -* `GKFS_USE_GUIDED_DISTRIBUTION` ON -* `GKFS_USE_GUIDED_DISTRIBUTION_PATH` `` +The `trace_reads` module enables a `TRACE_READS` level log at the clients writing the I/O information of the client which is used as the input for a script that creates the guided distributor setting. +Note that capturing the necessary trace records can involve performance degradation. +To capture the I/O of each client within a SLURM environment, i.e., enabling the `trace_reads` module and print its output to a user-defined path, the following example can be used: +`srun -N 10 -n 320 --export="ALL" /bin/bash -c "export LIBGKFS_LOG=trace_reads;LIBGKFS_LOG_OUTPUT=${HOME}/test/GLOBAL.txt;LD_PRELOAD=${GKFS_PRLD} "` + +Then, the `examples/distributors/guided/generate.py` scrpt is used to create the guided distributor configuration file: +* `python examples/distributors/guided/generate.py ~/test/GLOBAL.txt >> guided_config.txt` + +Finally, modify `guided_config.txt` to your distribution requirements. ###
