Hi all,
I am having troubles understanding the outputs generated by valgrind.
I compile my fortran code with the following flags: -c -tp x64 -r8 -i4
-Mnolre -Mnovect -Mnounroll -g
I start it using valgrind doing: valgrind --tool=memcheck --leak-check=full
./rsiNE 54 2002SK1 NAEUa
rsiNE is a csh script starts the code with some parameters and file names
doing:
#!/bin/csh
./paleonSG<< EOF >& out.pal
4 1 1
02
...
...
...
EOF
I use Valgrind-3.5.0 and added the apport-valgrind package
The output results are:
