Hello the problem was a very bad programming that I did, I defined this counters to count the number of the access depending on the src:
static double My_counters[9][9]; I did that for SE mode and using the flags I verify that the maximum src number for SE it was 9, so I put that 9 in the definition after I forgot to change the size and I switch to FS. In FS mode the src numbers are bigger so in my code it was writing in other memory space, and you can imagine the problem. Sorry about this stupid problem and thanks for the help Ali. I would like to seize the opportunity of send this email, and ask Joel if he can give us the estimated simulation time for the benchmarks. Thanks.
