SMPI profiles do not handle absolute trace filenames
Just tried and it gave me this error:
[0.000000] /home/carni/proj/batsim/src/profiles.cpp:621: [root/CRITICAL] Invalid JSON: profile 'LU.S.4' has an invalid 'trace' field ('/tmp/simgrid-template-smpi/NPB3.3-MPI/LU.S.4'), which leads to a non-existent file ('/tmp/meh/.//tmp/simgrid-template-smpi/NPB3.3-MPI/LU.S.4')
