[Starpu-devel] help with trace.rec and tasks.rec

[Alfredo Buttari <alfredo.buttari@enseeiht.fr>]

Hello,

for some reason I am getting no "Task" events in the trace.rec file. As a result, the starpu_trace_state_stats.py is printing something like this (obtained running examples/cholesky/cholesky_grain_tag -size 2048)

$ starpu_trace_state_stats.py trace.rec | column -t -s ","

"Name"             "Count"  "Type"     "Duration"

"Initializing"     2        "Runtime"  0.108658

"Overhead"         4538     "Runtime"  79.911275

"Idle"             1514     "Other"    0.579661

"Scheduling"       3024     "Runtime"  1.635756

"Sleeping"         28       "Other"    52.331106

"FetchingInput"    1512     "Runtime"  1.332104

"PushingOutput"    1512     "Runtime"  0.807078

"Submitting task"  1512     "User"     1.968799

am I doing anything wrong?  Second question, is there any tool to parse the tasks.rec file? In what should the tasks.rec and trace.rec files differ?

Ciao

Alfredo
