Grow with the Community: Engagement w/ChinaSys and APSys

AsiaSys

APSys ChinaSys

9 Years Ago (Nov. 2008)

The Story of ChinaSys

• Online discussion began during organizing APSys 2011 (prior

code name: DeepSea)

• Initial idea by ZZ, and make it real together with Wenguang, Lidong

and Haibo

• Founding discussion right after the banquet of APSys
• ZZ, Wenguang, Binyu, Xiaofei, Yingwei, Yinhe, Yu, Yungang, Xiaolin,

Haibo, etc…

• Inaugural workshop: Chair: Wenguang, Shenzhen after CNCC
• 2nd: Chair: Haibo, Hangzhou, 3rd: Chair: Xiaofei, Wuhan
• 4th: Chair: Yungang&Yinhe, Beijing, 5th: Chair: Yu, Suzhou
• 6th: Chair: Li, Changsha, 7th: Chair: Yingwei, Shenzhe
• 8th: Chair: Zhibin, Xiamen, 9th: Chair: Haibo/Weihua, Shanghai
• 10th: Chair: Xiaofei, Wuhan, 11th: Chair: Yungang, Shanghai

Becomes the third SIGOPS chapter since August 2015

Original Goal

• Form a “club” with faculties from several research groups,

invitation only.

• The faculties are the young working horses, instead of already

established.

• Every half year, one of the club member will be the host of the

1day event.

• Faculties take their senior students, and MSRA research team (in

most cases the entire team) will join for a one day retreat.

• Opportunistically, we will invite one external senior

researchers(not necessarily from any of the members).

• The goal is brainstorm and plan on works that will push this small

community to reach for an ambitious and yet achievable milestones.

• For the system discipline, it would something

likeSOSP/OSDI/ASPLOS papers. Ideally, this is to promote collaboration among the members

We Are Growing and Stronger Since!

• Numerous papers published in top systems conferences like

SOSP/OSDI, EuroSys, Usenix ATC, and top architecture conferences like ISCA, MICRO, HPCA, ASPLOS

• 2015 (Incomplete)
• 1/30 SOSP paper
• 3/32 EuroSys papers (1 best award)
• 5/47 ATC papers
• 3/23 PPoPP papers
• 5/58 ISCA papers
• 2/48 ASPLOS papers
• Others: 2/29 MobiSys, 2/60 Usenix Security,
• Several best paper awards/nominee: ASPLOS, MICRO, HPCA,

EuroSys, APSys

Community Services: Help You, Help Me!

• 2017 ACM SOSP General Chair (w/ Lidong

Zhou@MSR)

• ACM APSys Steering Committee Chair (w/

Lorenzo Alvisi@Cornell)

• ChinaSys Co-founder (2011), ACM SIGOPS

ChinaSys Vice Chair (2015)

• PC: SOSP

, EuroSys, Usenix ATC, ISCA, ASPLOS, Oakland, PPoPP , CCS

Outline

• Self-introduction
• Growing with the Academic Community
• Experiences in Academia and Industry
• Interaction b/w Academia and Industry
• Mind the Gap: Academia vs. Industry
• Some Experiences

Academia vs. Industry

Academia: Innovation & Incubation Industry: Platform & Product

Difference b/w Academia and Industry

Paper (+prototype) vs. Product P2P vs. Hierarchical Hypothesis-oriented vs. market-driven Free vs. well-organized Scientific insights vs. market insights

Difference b/w Academia and Industry

Time constraint: paper deadline vs. time to market Impact: knowledge vs. product Persistent vs. fast changing Communication/interpersonal skills

Mind the Gap: Be Careful of Flexibility

We build stuffs with flexibility

Reinvent a wheel! Invent an irrelevant wheel!

Mind the Gap: Eco-system Matters

• It is usually hard to destroy an existing eco-

system

• High risk research: find chances for a

revolution

• Low risk research: fix critical issues when

evolving existing eco-system

• Key: needs an evolutionary path

Mind the Gap: Last Mile is Really Long

• Belief: I build a good system with

innovative ideas, industry will definitely adopt it into its product

• Reality: industry cares a lot on the maturity
• f a system due to pressure on TTM, you

usually have some competitors

• Suggestion: do last mile work yourself if

you really want to push work into industry

Mind the Gap: Last Mile is Really Long

• A long way to go from a research prototype to

a product

• A research paper only finish ~1/10 of the journey
• Lots of traps ahead from research prototype

to a product

• Compatibility issues
• Reliability issues
• Deployment efforts
• Dirty work to hacking
• Need a strong incentive to do so: 10-100X

performance improvement, a revolutionizing security foundation

Mind the Gap: Complexity

• Computer systems are already very

complex

• Academia: usually needs to make some

simplified assumptions to conduct research

• Industry: 10+X complexity when applying a

research idea back

Tip: Gaining Insight on the Technical Trend

• Make sure it aligns with trend with industry
• Industry: 1-2 years ahead for product line,

2-5 years ahead for research lab

• Academia: 3-10+ years ahead
• Constraints: Time to Market

Tip: A Typical Way of Research： Incommensurate Scaling

As a system increases in size or speed, not all parts of it (&human factors) follow the same scaling rules

• - Saltzer & Kaashoek

X 10 million =

Key: skeletal system

Tip: Incommensurate Scaling

Examples: Memory wall: CPU speed increases faster Multicore scalability: #core increases faster Mobile security: security not match open infrastructure In-memory computing: data access > 1,000X faster

As a system increases in size or speed, not all parts

• f it (and human factors)

follow the same scaling rules (Saltzer and Kaashoek )

But the Gap Considered Useful

• A gap helps distinguish academia and industry
• Academia: cutting-edge research with great

flexibility

• Industry: comprehensive full solution,

customer-oriented

Summary

• Grow with the community: help you, help

me!

• From academia to industry
• Mind the gap
• Cope with fast changing world
