Test25 - Concurrent cases executing in 2 and 4 machines compared to a centralized scenario

1 to 20 concurrent cases compared to 1 to 20 centralized cases executing in 2 and 4 hosts. Hosts: araguaia.dcc.unicamp.br, iguacu.dcc.unicamp.br, anhumas.dcc.unicamp.br and tigre.dcc.unicamp.br
Centralized Execution Scenario: araguaia    
Single sequence without splits.      
The same activity, with the same data set is executed durint each task      
       
Distributed Execution Scenario: araguaia and iguacu    
Cases execute in a single sequence of equal activities, without splits and joins.      
Activities alternate between two machines: consecutive activities execute in different hosts.      
Case, process and role coordinators ececute in host araguaia      
The taskLists (2) execute in host iguacu.      
The test is started from host iguacu      
The same data set is read by all activities      
       
Distributed Execution Scenario: araguaia, iguacu, anhumas and tigre    
Cases execute in a single sequence of equal activities, without splits and joins.      
The users are allocated at runtime in random order. Since each user (tasklist) is executing in a different host, the host of the next activity is choosed at runtime.      
The activities are created in the user preferential host.      
Hence, activities alternate between three machines: araguaia, iguacu and tigre. Consecutive activities may execute in the same host.      
Case, process and role coordinators ececute in host araguaia      
The TaskLists execute one in each host: araguaia, iguacu and tigre, each one representing one user.      
All coordinators execute in host anhumas.      
The test is started from host araguaia.      
The same data set is read by all activities      
       
Hosts: araguaia.pos.dcc.unicamp.br; iguacu.dcc.unicamp.br; anhumas.dcc.unicamp.br; tigre.dcc.unicamp.br
