Installing Integrated Manager for Lustre software on Intel® Xeon Phi™ Coprocessors

In this Chapter:

Install Lustre client on an Intel® Xeon Phi™ Coprocessor

To install Lustre, install the following two RPMs on the Intel® Xeon Phi™ coprocessor (not on the host).

# rpm –ivh lustre-client-mic-<version>.x86\_64.rpm

# lustre-client-mic-modules-<version>.x86\_64.rpm

In case of issues with dependencies, add the –nodeps option.

After restarting the MPSS service, the Lustre client will appear on the coprocessor card.

Configure Lustre for the Intel® Xeon Phi™ Coprocessor

Configuring Lustre for the Xeon Phi Coprocessor is easy. You only need to specify the LNET configuration in /etc/modprobe.d/lustre.conf file.

To check configuration, enter the following commands.

# ssh mic0

# echo 'options lnet networks="o2ib0(ib0)"' > /etc/modprobe.d/lustre.conf

# modprobe lustre

# mkdir -p /mnt/lustre

# mount.lustre <MGS\_IP>@o2ib0:<lustre\_FS\_name>;
/mnt/lustre

To make this configuration persistent across re-boots, enter the following commands (where “X” is the card number).

# mkdir -p /var/mpss/micX/mnt/lustrefs

# echo 'dir /mnt/lustrefs 0755 0 0' >> /var/mpss/micX.filelist

# mkdir -p /var/mpss/micX/etc/modprobe.d

# cp /etc/modprobe.d/lustre.conf /var/mpss/micX/etc/modprobe.d/

(or just create it in /var/mpss/micX/etc/modprobe.d/)

# echo 'file /etc/modprobe.d/lustre.conf etc/modprobe.d/lustre.conf 0644 0 0' >> /var/mpss/micX.filelist
