working directory (if the current working directory is writable). To change the path on
which the log file is written, use the
--outfilepath
option:
# gpumodeswitch --listgpumodes --outfilepath /tmp/
Note:
when using the bundled Linux bootable images (see section 2.4), the system
boots into a read-only file system. Log files can be generated by using the
outfilepath
option to write the log files into
/tmp
.
The log file summarizes GPU modes:
