+This is an example of the replay of several traces in the same simulation, to watch how they interact on a platform.
The main item of this example is the description file
-The description_file file is an example of the launching of 2 replay traces
-(both of the same application/size).
+The description_file file is an example of the launching of 2 replay traces (both of the same application/size).
Each line has the form :
2 smpi_replay.txt 32 125000000000
-This launchs an instance "2" that will replay file smpi_replay.txt with 32
-processes, and each one of these processes will sleep for 125000000000 flops
-before the run.

+In order to be replayed, a deployment file must be generatedfrom this description file, and from the intended platform
+file and hostfiles. The script generate_multiple_deployment.sh can be used as such :
-In order to be replayed, a deployment file must be generated
-from this description file, and from the intended platform file and hostfiles.
-The script generate_multiple_deployment.sh can be used as such :
+./generate_multiple_deployment.sh -platform platform_file.xml -hostfile hostfile description_file deployment.xml
-./generate_multiple_deployment.sh -platform platform_file.xml
- -hostfile hostfile description_file deployment.xml
-
The output deployment file will be written in deployment.xml
-Please not that the deployment will use the hostfile in order, placing processes
-of the first instance using the first node, and the ones of the following
-instances on the following nodes.
+Please not that the deployment will use the hostfile in order, placing processes of the first instance using the first
+node, and the ones of the following instances on the following nodes.
The actual replay can now be launched, using classic options for SMPI
./replay_multiple description_file platform_file.xml deployment.xml --cfg=... --log=...
