| <h1>Intel Xeon Phi (KNC) MPSS software and kernel modules for CentOS 7&8</h1> | ||
|
|
||
| The Intel Xeon Phi 0x100 (KNC) PCI-e accelerator card is/was a many-processor card | ||
| to speed up calculations. The idea is similar to that of a GPGPU like NVidia or AMD, | ||
| but based on many Intel cores stuffed into a single PCI-e card, together with a | ||
| fair amount of RAM (up to 16 GB, depending on the model). | ||
| <br><br> | ||
| In order to access the card, you have to install and run the Intel MPSS software stack, | ||
| which consists of a Linux kernel module (or Windows, but that is not applicable here), | ||
| combined with a set of user-space applications. | ||
| <br><br> | ||
| Unfortunately, Intel dropped support for this Xeon Phi card somewhere in 2019, | ||
| leaving users stranded with a software stack that supported (amongst others) RedHat | ||
| Enterprise Linux 7 up to release 7.4 (kernel 3.10.0-693). | ||
| <br> | ||
| The latest version (as of October 4th 2019) of the MPSS software stack for the | ||
| first generation Intel Xeon Phi (aka KNC) is 3.8.6. Unfortunately, this version | ||
| of the mpss stack does not support the newer RHEL/CentOS 7 kernels nor does it | ||
| support RHEL/CentOS 8 at all. | ||
| <br><br> | ||
| Even though Intel released version 3.8.5 well after RHEL 7.5 and 7.6 were released, | ||
| and similarly, released version 3.8.6 after RHEL 7.7 was released, | ||
| they state that this newer release only addresses critical customer issues and | ||
| security hotfixes. Apparently, they find it important to address security issues | ||
| in the MPSS stack and the KNC itself, but they do not care about security issues | ||
| (SPECTRE anyone?) in the host operating system. | ||
|
|
||
| <br><br> | ||
| In order to continue to be able to use the few Xeon Phi's that I have, I have created | ||
| patches for the mpss-modules source files, so that it can be compiled on newer RedHat/ | ||
| CentOS Linux kernels, including | ||
| <ul> | ||
| <li>CentOS 7.5 (kernel 3.10.0-862)</li> | ||
| <li>CentOS 7.6 (kernel 3.10.0-957)</li> | ||
| <li>CentOS 7.7 (kernel 3.10.0-1062)</li> | ||
| <li>CentOS 7.8 (kernel 3.10.0-1127)</li> | ||
| <li>CentOS 7.9 (kernel 3.10.0-1160)</li> | ||
| <br> | ||
| <li>CentOS 8.2 (kernel 4.18.0-193)</li> | ||
| <li>CentOS 8.3 (kernel 4.18.0-240)</li> | ||
| <li>CentOS 8.4 (kernel 4.18.0-305.3.1)</li> | ||
| <li>CentOS 8.5 (kernel 4.18.0-348.2.1)</li> | ||
| </ul> | ||
|
|
||
| Note that the mpss-modules source tarballs from Intel for MPSS 3.8.4, 3.8.5 and 3.8.6 seem different, but | ||
| a <code>diff -r</code> on the source trees resulted in <b>zero</b> difference. Thus, if you are stuck | ||
| running an older version of the MPSS software stack then you can apply the same patches. | ||
|
|
||
| <br><br> | ||
| You can find these patches on the following pages, as well as an outline of how to get | ||
| the MPSS software stack running on Ubuntu 18 (kernel 4.15). | ||

| <h1>Intel Xeon Phi (KNC) MPSS modules for CentOS 7.5, 7.6, 7.7, 7.8 and 7.9</h1> | ||
|
|
||
| The latest version (as of October 4th 2019) of the MPSS software stack for the | ||
| first generation Intel Xeon Phi (aka KNC) is 3.8.6. Unfortunately, this version | ||
| of the mpss stack does not support the newer RHEL/CentOS 7 kernels <b>3.10.0-862</b> | ||
| (7.5), <b>3.10.0-957</b> (7.6), <b>3.10.0-1062</b> (7.7), <b>3.10.0-1127</b> (7.8) | ||
| and <b>3.10.0-1160</b> (7.9). | ||
| <br><br> | ||
| Therefore, I've grabbed the mpss-modules source tarball and patched it, so that it can | ||
| be compiled for a 3.10.0-862, 3.10.0-957, 3.10.0-1062, 3.10.0-1127 or 3.10.0-1160 kernel. | ||
| The resulting RPM and Source RPM (SRPM) can be download here, both for MPSS 3.8.6 and the | ||
| previous 3.8.5 release. The same patch is used for the 3.10.0-862 and 3.10.0-957 kernels, | ||
| but for the 3.10.0-1062 patch, the file <code>micscif/micscif_select.c</code> needed a small | ||
| patch. For the 3.10.0-1127+ patch, the file <code>host/vmcore.c</code> was patched to work | ||
| around an overlapping function name. | ||
|
|
||
| <h2>MPSS 3.8.6 on CentOS 7.9</h2> | ||
| <ul> | ||
| <li>RPM: <a href="mpss-modules-3.10.0-1160.el7.x86_64-3.8.6-4.x86_64.rpm">mpss-modules-3.10.0-1160.el7.x86_64-3.8.6-4.x86_64.rpm</a> | ||

| </ul> | ||
| Note that this RPM is much small than its predecessors due to the addition of a line | ||

| to the <code>mpps-modules-3.8.6-centos79.spec</code> file. | ||

||
| <h2>Installation</h2> | ||
|
|
||
| You can install or upgrade the <code>mpss-modules</code> file using | ||
|
|
||
| <pre> | ||
| rpm -ivh https://www.nikhef.nl/~janjust/mpss/mpss-modules-3.10.0-1160.el7.x86_64-3.8.6-4.x86_64.rpm | ||
| </pre> | ||
|
|
||
| <b>Note</b> | ||
| <br> | ||
| Normally, a <code>weak-updates</code> link is created when a module is installed, e.g. | ||
| <pre> | ||
| $ ls -al /lib/modules/3.10.0-862.6.3.el7.x86_64/weak-updates/ | ||
| total 4 | ||
| drwxr-xr-x 2 root root 20 Jul 5 16:58 . | ||
| drwxr-xr-x 7 root root 4096 Jul 5 16:58 .. | ||
| lrwxrwxrwx 1 root root 47 Jul 5 16:58 mic.ko -> /lib/modules/3.10.0-862.el7.x86_64/extra/mic.ko | ||
| </pre> | ||
|
|
||
| This link is needed for the existing kernel to find the <code>mic.ko</code> file. If the module cannot | ||
| be found after installing the <code>mpss-modules</code> RPM then you can simply create it yourself, or | ||
| re-install the kernel RPM. | ||
