[mOS configuration]
by Min-Woo Ahn
Hello users,
I tried to configure mOS for "Intel Xeon CPU E7-8890 v4, 2.20GHz" which has
96 cores(4 NUMA nodes) and I failed to use yod.
As I configured before(when I was using Intel Xeon CPU E5-2640, 16 cores),
I use core 0 as isolated and destination of syscall delegation. And remain
cores are used as lwkcpus.
When I booted mOS and tried to run simple command with yod and it shows
message "Killed". How can I solve this problem?
My GRUB_CMDLINE_LINUX is as below,
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8 selinux=0
rd.lvm.lv=cl/root
rd.lvm.lv=cl/swap intel_idle.max_cstate=1 intel_pstate=disable
nmi_watchdog=0 mce=ignore_ce tsc=reliable transparent_hugepage=never
isolcpus=0 lwkcpus=0.1-95 lwkmem=0:32G,1:32G,2:32G,3:32G lwkmem_debug=0"
Thank you.
Minwoo.

GPU execution on mOS
by Jaehyun
Hi. My name is Jaehyun and I'm using mOS kernel in my research.
I have a question about GPU execution on mOS kernel.
When I was running GPU benchmark (name is SHOC) in mOS kerenl by using
Linux core like below image, this benchmark was executed well.

However, when I was running this benchmark in same mOS kernel by using
mOS(LWK, yod command) core like below image, mOS kerenl was printed
SEGMENTATION FAULT.

Is there any problem when I was running GPU benchmark? Or mOS kerenl do not
support GPU application currently?
Thank you.
