Re: [Starpu-devel] Error in .starpu/sampling

[Xavier Lacoste <xl64100@gmail.com>]

Hello,

I add some exchanged with TGCC help team.

It seems that changing the STARPU_HOME by a relative path is a correct workaround.

 "if ((_starpu_mkpath(up, mode) == -1) && (errno != EEXIST))" fails when trying to create subdirectory it is not allowed to create such as /ccc/cont003/home/gen1567/ (and that exists...).

My workaround :

cd $WORKDIR

export STARPU_HOME=starpu_home

ccc_mprun ./my_binary <my_options>

Have a nice day,

XL.

Hi Xavier,

I do not think the error is directly related to StarPU. It seems for whatever reason, you do not have the right to write in your home directory.

Try to call by hand

mkdir -p /ccc/cont003/home/gen1567/lacoste/.starpu/sampling/

If that does not work, you should contact the CCRT system team. In the meantime, you can set the environment variable STARPU_HOME to another directory (for which you have the write permission).

Cheers,

Nathalie

Hello,

On curie from CCRT I get the following error when trying to run on the hybrid partition:

Error making StarPU directory /ccc/cont003/home/gen1567/lacoste/.starpu/sampling/:
mkdir: Read-only file system 

Do you have already experience such an error ?
Any idea what to do to avoid this ?

Regards,

XL
