Re: [Starpu-devel] starPU writes to /usr/local

Thank you, Nathalie. I did, at some points, set that variable that way. My problem is solved.

Hello,

You seem to have set the environment variable STARPU_HOME to /usr/local

Unset it or set it to a directory to which you have write permission, and it should be fine.

Cheers,

Nathalie

I'm having trouble with starPU runtime. It was working fine until a beautiful day and it started behaving out of expectation. Basically, when I ran my starPu application, the starPU library tried to create a folder in /usr/local/ and thus violated the privilege. I'm not sure why this happen. Below is the detail message.

Plus, although I didn't configure starPU with --enable-debug, the message still appeared. And I had the STARPU_GENERATE_TRACE=1 when I ran the application but no trace was generated either.
