67 * - "CLM03": realistic TCP behavior + basic CPU model (see [CML03 at CCGrid03]) + support for parallel tasks
68 * - "KCCFLN05": realistic TCP behavior + basic CPU model (see [CML03 at CCGrid03]) + failure handling + interference between communications and computations if precised in the platform file.

71 * \param pa A va_list with the others parameters
