Uninstall the previous version of the MPSS and install the new MPSS using the instructions in
section 2.3 of
readme.txt
.
3.
Update the flash on your card(s) as detailed in section 2.4 of
readme.txt
4.
Reboot the system
5.
Start the Intel® Xeon Phi™ Coprocessor (while you can set up the card to start with the host
system, it will not do so by default), and then run “
micinfo
” to verify that it is set up properly:
sudo service mpss start
sudo micctrl -w
/usr/bin/micinfo
Make sure that the Driver Version, MPSS Version and Flash Version are verified according to table
1 in the previous section.
Regaining Access to the Intel® Xeon Phi™ Coprocessor after Reboot
The Intel® Xeon Phi™ Coprocessor will not start when the host system reboots. You will need to manually start
the Intel® Xeon Phi™ Coprocessor, and then run “
micinfo
” to verify that it started properly. You may need to
add
/usr/sbin
and
/sbin
to your path to do this successfully as a non-root user via
sudo
:
sudo service mpss start
sudo micctrl -w
/usr/bin/micinfo
Note: It is possible to make the coprocessor uOS automatically start on reboot and preload desired files. See
section 19.12 of the
MPSS
User’s Guide
for details
Restarting the Intel® Xeon Phi™ Coprocessor If It Hangs
If a process running on the Intel® Xeon Phi™ Coprocessor hangs, but the coprocessor is otherwise responsive
via
ssh
, log onto the coprocessor and kill the process like any other Linux process.
When a coprocessor hangs, and is inaccessible or unresponsive via
ssh
, there are two ways to restart it. But
first, see if you can tell what is happening:
sudo micctrl –-status
<micx>
