mos's Introduction
What is mOS for HPC
===================
mOS for HPC is an operating systems research project at Intel, targeting
extreme scale HPC systems deploying converged workflows for modeling /
simulation, data analytics, and AI. It aims to deliver a high performance
computing environment with the scalability, low noise, and repeatability
expected of lightweight kernels (LWK), while maintaining overall Linux
compatibility that HPC plus AI / ML applications need.
mOS for HPC remains under development at this time. These materials are being
made available to interested parties to explore, to test drive, and to provide
feedback through the mailing list. It is not intended to be used for business
critical uses. The ability to compile, install, and boot a Linux kernel is
required to get mOS up and running. A good understanding of what an OS does and
how it interacts with the underlying hardware is needed to configure the LWK
partition and get the most out of it. Support is limited by the development
team's ability to respond through the mailing list.
New for v1.0
============
- Based on SLES15 SP4 version of Linux 5.14.21 from github.com/openSUSE
- GPU ressource management support
- Dependency on Intel OneAPI Level Zero APIs
- New yod options to control GPU reservations
- Bug fixes
Where to get code
=================
The mOS for HPC source can be checked out from GitHub at
https://github.com/intel/mOS. Please see the Administrator's Guide
for further instructions.
Where to ask questions
======================
Register for the mOS for HPC mailing list at

Can i run on virtual machine environment centos7?
Hello, i want to run the mos 0.9 version, because we only have current resource setting.
Resource detailed list :
virtual machine : vmware workstation 16 Pro 16.2.2 build-19200509
linux distribution and grub version ： centos 7 + grub2
1、we compiled the most source code , generated the kernel-5.10.46.0.9.mos.x86_64.rpm file, and used "rpm -ivh --force " command to install the kernel rpm file.
2、we updated the "etc/default/grub" file content:
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8 selinux=0 rd.lvm.lv=centos/root rd.lvm.lv=centos/swap intel_pstate=disable nmi_watchdog=0 kernelcore=2G nohz_full=1-3 , and excuted the grub2-mkconfig operation code order:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
3、reboot.
Alought we can saw the grub menu item windows and selected it, system dracut mode(emergency fault mode ) was entered.
The picture was showed below:
we compared the original linux kernel upgrade operation. For example, we upgraded centos7 linux kernel version and grubed successfully the system. But, with the same operation, The clicked and selected mos-v0.9 system item entered the emergency mode(dracut mode). It's not worked.
how we can solve the problem. we have searched the whole online solutions, but the problem is still difficult.
Thank you very much~
how could I join a kernel developer
Hello, how could I join a kernel developer.
I am interested in this part and may submit some patches.
The return value of 'sscanf()' should be checked

Can I use yod to mmap for a memory larger than 128M?
As far as I know, the system physical memory block size is 128M, but why can yod only allocate one memory block to mmap? Is there any other way to make yod allocate more memory to mmap?
My test method is as follows:
yod -o lwkmem-prot-none-delegation-enable -M 2048m -C all --mosview lwk ./maptest --verbose --type anonymous --size 4096 --num 32512
Test Results
Failed mmap. Cannot allocate memory
