3. Why do we need supercomputers?
1. Meet to the general computing need
of individuals (entertainment, office
work, relatively simple computing…)
2. Low cost, flexible and convenient
3. Optimized to personal need
Personal computer (PC)
1. Meet to the specilized computing of
enterprises (file, web, mail, data,
application software servers…)
2. Each enterprise has may have one or
more independent servers with capital
expense (CAPEX) and operation
expense (OPEX) are relatively high.
3. Optimized to enterprises who are big
enough, have strong IT team and high
IT budget.

Supercomputer is a system
connecting many servers
together (may be up to
hundreds thousands of
servers) in parallel and
distributed ways.
Why do we need supercomputers?

5. 2.Parallel and distributed computing
allow individuals, organizations and
enterprises to use the compute and
storage power of supercomputers in
parallel.
Parallel computing allows to
deploy unlimited applications

7. 4.Meet the needs of specialized and
general purpose computing of
individuals, organizations and
enterprises (entertainment, office work,
simple and complicated computing)
Supercomputers also meet the needs of
popular computing of organizations and
enterprises such as file, web, mail, data
and application software servers…
Unlimited applications run on

Compute servers:
• Each compute server has many CPUs, each
CPU has many cores (multicores) and high
chipset frequency.
• Memory capacity (RAM) is up to hundreds of
GBs per server
Storage servers:
• Storage capacity is about tens or hundreds of
terabytes per server, including SSD (read/write
optimized) and HDD (storage optimized)
I/O Network:
• Gigabit Ethernet & 10GbE standard

10. Epfen Supercomputer
Operating system:
• Using open source operating system
Linux/Unix in order to optimize
performance and licenses.
RAID:
• Using “soft” RAID of Linux operating
system with industrial standard RAID 5.
“Soft” RAID allows to extend many
harddisks easily
2. Software

11. Epfen Supercomputer
Filesystem:
• Using filesystem (using mainly the
operating system Linux/Unix) in order to
optimize system performance, to partition
storage easily and to extend volumes
unlimitedly.
Virtualization
• We don’t use any virtualization softwares
such as VMware, Hypervisor, Openstack…
in order to optimize system performance and
license
• We only use filesystems
Filesystem of Epfen supercomputer
inherits the filesystem of Linux/Unix
kernel in order to optimize system
performance and licenses

12. Containerization:
• Using open source softwares in order to
containerize the system.
• Containerization helps build and deploy
independent applications fast and effectively.

Application space:
• By using virtualization softwares above,
Epfen supercomputer becomes a “factory of
unlimited containers”.
• Containers are independent
compute/storage units, which can install its
own operating system; each container can
deploy one or more applications in parallel.
