I recently had the opportunity to spend a couple of weeks in Japan meeting with HPC users and technologists. I came away from the experience with some new perspectives, and I wanted to share these with you.
Lets take a look at each of these in a bit more detail …GPU Uptake is Strong
Real estate agents have a mantra: Location. Location. Location. This single word is repeated three times solely for emphasis. Each time I travel to Japan, I’m reminded of a similar mantra: Localization. Localization. Localization. Is this really worth emphasizing?
Suppose you’re visiting Japan. In the metropolitan Tokyo area, you’ll find English-language options that’ll allow you to make use of the extensive rail and subway systems - from signs and kiosks, to people as well as, of course, apps for your smartphone. These English-language aids dwindle as you move away from the metro Tokyo area - ultimately making it a challenge to get from A to B.
In this and four previous trips, I’ve met native Japanese speakers with varying degrees of fluency in English - from excellent to non-existent. And even for those who have some degree of fluency, it’s more than just a cultural courtesy to engage them in their native tongue.
Localization is one of the key reasons it makes sense for foreign companies to work through partners. With our support, partners like HPCTech represent Bright Cluster Manager localized for the Japanese marketplace - for a compelling illustration, please have a look at HPCTech’s Web page for Bright here. This is a lot more than just knowing how to do business in Japan. It’s also about value-added technical services from initial consultations, through purchase, to delivery and ongoing support.
I made a number of presentations during my trip. None, however, was without the aid of a partner acting as a facilitator from a language perspective. In some cases, the partner translated my words sentence by sentence, and even when this wasn’t necessary, it was customary for some of the discussion to take place in Japanese - from the framing of technical questions, to the cultural nuances of doing business.
NVIDIA deserves kudos for grokking (click here for a definition of "grok") the importance of localization. Through simultaneous translation, every presentation in every room was available in Japanese and English. And even though most of the opening keynote was delivered in English by NVIDIA staff, most slides were localized for the Japanese audience.
Even the logistics were localized. As in the past, when I attended GTC Japan 2012, this year’s event was held at Tokyo Midtown. This excellent venue is highly accessible for metropolitan and intercity commuters. The opening keynote started at a commuter-friendly 10 am local time. From start to finish, NVIDIA programed a GPU-immersive experience that sustained a frenetic pace. My talk was scheduled for the end of the program - to start at 5:30 pm. Having been to Tokyo a few times, I was not at all concerned, as I knew time-of-day would not factor into attendance - and it didn’t. Following the program, NVIDIA ended the day with a reception - an opportunity to network, refresh and celebrate each others’ success. That’s GTC Tokyo-style - to use an adjective I learned from HPCTech CEO Okuyama-san.
Speaking of localization, I learned something else from Okuyama-san: TSUBAME is not an acronym! In fact, in Japanese tsubame means swallow - as in the bird that can eat insects while flying. If you look at TITech’s logo, you’ll notice a swallow. So, TSUBAME the supercomputer is named after the swallow on the TITech logo. I’m not sure how to interpret the on-the-fly ability to ingest insects though …Scalable Physical Infrastructure
I’ve spent all of my IT career in infrastructure. From infrastructural software for HPC, to the hardware and software that deliver campus IP data networks, scalability has always been on my radar. Each time I visit Tokyo, I’m astounded by its scalable infrastructure.
The population of Tokyo is estimated to be in excess of 13 million as of May 2014. According to Guinness World Records, the skyscraper district’s Shinjuku Station services in excess of 3.5 million passengers per day - yes, per day! Although I could continue to relate stupefying stats, the point is this: Tokyo thrives on a scalable physical infrastructure.
In addition to being scalable, Tokyo’s rail and subway systems are extensive and affordable. In all of my business trips to the Tokyo area, locals, expats and enlightened visitors, make use of these services for getting around the metropolitan Tokyo area. For intercity transit, the Shinkansen (aka. bullet trains) speak volumes to those of us with a need for speed by traveling up to 240–320 km/h (150–200 mph) <gulp!> Now that is scalable, high-performance infrastructure! Frankly, there are many other parts of the world (including North America) that could learn a lesson or three from Japan, and Tokyo in particular.Practicality Trumps Formality - Except inthe Datacenter
Temperatures sit in the mid 30s on the Celsius scale (mid 90s Fahrenheit) in July. Factor in the humidity, and you’re looking at Tokyo summers of mid 40s (low 100s Fahrenheit). Not exactly ideal weather for schlepping around a laptop in a suit and tie, while taking public transit!
Whereas office buildings offer some relief from the urban outdoors, some is the operative word here. In the wake of the devastating March 2011 Tohoku earthquake and tsunami, demand for electricity continues to outstrip supply, as most of Japan’s nuclear power generating stations remain off line. (In fact, while I was in Japan, there were discussions of the review phase winding down, and nuclear power plants being gradually re-introduced into service.) As an interim measure, the Japanese government established a guideline that sets air conditioning at a balmy 28 °C (about 82 °F).
Adaptation notwithstanding, summer attire for business purposes has become progressively, and pleasantly, much more relaxed. My jacket and tie were confined to my hotel room, as I navigated the subway and JR (Japan Rail) sporting just a shirt and slacks. Next time, short-sleeved shirts!
While people adjust their attire to cope with summer, the datacenter is less compromising. Though leaders from price/performance and energy efficiency perspectives GPU-based configurations, like those offered through HPCTech, still generate heat. For a country whose starting point is currently (sorry ;-) an electricity deficit, the need to dissipate the heat generated in its datacenters is of pressing concern. From the groundbreaking Earth Simulator in 2002, to TSUBAME and RIKEN’s K Computer, it’s clear the Japanese have a compelling interest in energy efficient datacenters at scale. Since necessity is the mother of invention, perhaps the future will bring innovative datacenter solutions from Japan to the rest of the world.
Four of many lasting perspectives … and, enthusiastic anticipation of the next trip!
