Weird. I have just tried locally and the output for me looks like:

$ python2.7 tools/starpu_trace_state_stats.py trace.rec | column -t -s ","
"Name"             "Count"  "Type"     "Duration"
"Initializing"     4        "Runtime"  1.036028
"Overhead"         4540     "Runtime"  5.291885
"Idle"             1516     "Other"    0.60503
"Scheduling"       3026     "Runtime"  1.346616
"Sleeping"         30       "Other"    88.045689
"FetchingInput"    1512     "Runtime"  0.961838
"chol_model_21"    212      "Task"     100.915113 ---> This is what you 
want!
"PushingOutput"    1512     "Runtime"  0.587924
"chol_model_22"    1276     "Task"     890.891958
"chol_model_11"    24       "Task"     3.280441
"Submitting task"  1512     "User"     1.506503

This is with starpu-svn from today or yesterday.

Which version are you using?

I don't remember how to parse the tasks.rec, maybe there is a tool in 
trunk/tools, not sure though.

The main difference between tasks.rec and trace.rec is that the former 
contains more information about the tasks and the latter only contains 
the different states of the execution.
