Bonjour Nathalie,

Thank you for your reply. I was able to produce the results as per your suggestion.
I dont see this path $STARPU_PATH/lib/starpu/examples/ in my directory.
I am attaching the config.log file as requested by you:

I rechecked, the script indeed should be installed in $STARPU_PATH/lib/starpu/examples/

could you please send your config.log file to check what went wrong ?

and, you should make sure to use the documentation of the version you are using (for this section, there is no difference).

for the other versions, the link are available here https://files.inria.fr/starpu/

Cheers,

Nathalie

Hello,

The script you need to run should be in the  build directory.

build/tests/microbenchs/tasks_size_overhead.sh

Bonjour a tous,

I am using Starpu-1.3.4 version. I was trying to measure the task size overhead on miriel node using the instructions provided here: https://files.inria.fr/starpu/testing/master/doc/html/CheckListWhenPerformanceAreNotThere.html#CheckTaskSize.

I tried the following:

  1. As per the online manual, I checked here : $STARPU_PATH/lib/starpu/examples/ . But there are not files named tasks_size_overhead.sh here.
  2. tasks_size_overhead.sh named file exist in /home/ssimon/starpu-1.3.4/tests/microbenchs/ . But if I run it, I dont get any output,

These are the three files inside that folder.

tasks_size_overhead_sched.sh
tasks_size_overhead_scheds.sh
tasks_size_overhead.sh

I try running

[ssimon@devel03 microbenchs]$ bash tasks_size_overhead_scheds.sh
./microbench.sh: ligne30: ./../../tools/starpu_sched_display: Aucun fichier ou dossier de ce type

This means its looking for something called 'starpu_sched_display' in the tools path and failing when the relative path is wrong?

in tools, we only have 'starpu_sched_display.c'

Now if I try to find it,

[ssimon@devel03 starpu-1.3.4-woCUDA-woFXT]$ find . -type f -name "starpu_sched_display"
./build/tools/.libs/starpu_sched_display
./build/tools/starpu_sched_display
./install/bin/starpu_sched_display


Does this mean we are looking for starpu_sched_display in the wrong place on line 30 within the script ./microbench.sh ??

Am I doing something wrong here?

Is the procedure documented in any of the tutorials?

Merci beaucoup!
Bonne Journee!
