Open Frotier Lab.

We study Open Soruce Linux Kernel (ARM, x86, PPC)

OS Flatform (Android, Tizen)

Compiler (GCC, Clang & LLVM)

Hypervisor (KVM, Xen)

MPSoc (Multi Core)

Every Weekend OpenSource Study held on every Saterday

from pm 3:00 to pm 10:00

Source reading and analysis line by line

It takes Very long time study ARM Linux Kernel (+130 weeks)

MPSoc (+10 weeks)

Compiler (+50 weeks)

Orchestration & Provisioning:

Lifecycle of the delivery servise from service initial to service usage

Base polish:

- reduced costs (TCO)

- faster response times

- flexibility & responsiveness

- reduce errors
