Re: [starpu-devel] Subject: Feedback on ImportError when importing "starpu" in Python

[高家隆 <gaojialong@nudt.edu.cn>]

Sure, I find this function in starpu/src/core/perfmodel/perfmodel_history.c 
line1227 (Under MACRO #ifndef STARPU_SIMGRID)
and the branch and commit we can see:

starpu$ git log
commit 0ed088ceff3cdb71dd2c355caf5098e4f0213c81 (HEAD -> master, 
origin/master, origin/HEAD)
Author: Nathalie Furmento <nathalie.furmento@labri.fr>
Date:   Thu Nov 2 16:40:16 2023 +0100

    fixes for parallel workers

commit f5192aaceaa7dfcc0fcaa57f192156e534198011
Author: Nathalie Furmento <nathalie.furmento@labri.fr>
Date:   Thu Nov 2 13:59:52 2023 +0000

    Specify the number of cores in the architecture name
    
    This changes the name of the combination written in the perfmodel file to 
include its number of cores. Files with the previous format can still be read 
and loaded correctly and files written with the new format can be read with a 
previous code.

commit 0e3a32b5292558a044b4b3fa0eb49245ad3f0d09
Author: Nathalie Furmento <nathalie.furmento@labri.fr>
Date:   Thu Nov 2 11:49:29 2023 +0100

    check function hwloc_type_sscanf is available
