Re: [starpu-devel] Problem in running task size overhead benchmark in starpu

[Nathalie Furmento <nathalie.furmento@labri.fr>]

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).

https://files.inria.fr/starpu/testing/master/doc/html/CheckListWhenPerformanceAreNotThere.html#CheckTaskSize is for the master version

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

Cheers,

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!
