eXludus CEO Speaks His Mind ... and Then Some
You could say many things about eXludus CEO Benoit Marchand, but that
he's afraid to speak his mind is not one of them. In this captivating
interview with GRIDtoday editor Derrick Harris, eXludus CEO Benoit
Marchand not only covers the usual suspects -- who he is, why his
company is innovative, etc. -- he also expresses his views on issues
like global economics, how off-shoring affects the North American
economy, and the aesthetic aspects of software development.
GRIDtoday: For starters, what is your background in Grid computing and high-performance computing (HPC), in general?
BENOIT MARCHAND: My background in Grid computing dates back from
my time as a grad student at Universite de Sherbrooke and later
University of Waterloo, where I was conducting research in distributed
computing and, more precisely, working in distributed synchronization
problems. In 1985, I wrote a thesis on the use of file servers as
distributed processing gateways. That was before Apollo NCS -- later
known as DCE.
Then, I joined Silicon Graphics in early 1988 and was among the first
few to believe we could use their new 2-way R2000 processors to do high
performance computing, but realized that while RISC processing offered
undeniable price advantages, code tuning remained as complex and time
consuming as standard vector optimization. Moreover, SMP code
parallelization then was little known and hard work. Thus, optimization
complexity was a barrier to success. While managing SGI's technical
pre-sales activities in Europe -- including benchmarking activities --
I set out to develop new code optimization methodologies, develop
training materials and seminars, and eventually published a Web book --
the first I believe -- on that subject. We were able to reduce
substantially the time required to optimize an application from several
weeks to a day or so, eventually. This was key to SGI's success in HPC.
After nearly 10 years at SGI working the academic and research HPC
markets, I saw an opportunity to leverage emerging Grid throughput
processing technologies in the industrial sectors. I moved to Sun
Microsystems and took on the role of European HPC Business Manager. We
started to design, build, promote and sell our own cluster computing
products. Within two years, Sun Microsystems had moved from a No. 5
position to a market leader position in European HPC sales.
So, I've been directly involved in -- and hope that I have partially
influenced -- the evolution of distributed processing, Grid computing
and HPC for the past 20 years.
Gt: What is the story on eXludus? What inspired the formation of
the company, and what unique space does it fill in the Grid software
MARCHAND: Inspiration came from being close to my customers, in
listening and in seeking out opportunities to evolve their capacities
to design better products, to shorten time to design new drugs and to
better predict natural catastrophes. I'm passionate about science and
technology, not gadgets.
What people were telling me was simple: "We've invested a quarter
billion into bio-engineer desktops, why can't we use those more rather
than buying more high-end computers?" "To do accurate aircraft
structural analysis I need to scale my processing capacity to tens of
thousands of processors, how can we do that?" "We've purchased the
fastest network and the fastest file server, and still we can't feed
enough data to our processing nodes!"
Basically, they were telling me that Grid computing, as we do it today,
does not scale. For every problem there comes a time where you can't
scale the problem size or the Grid size anymore; marginal performance
gains diminish as things scale. Bottlenecks develop.
While my sales background was telling me, "Hmm, we can't sell upgrades
here anymore," my research background was crying, "How can we overcome
I left Sun in 2002 and started to work on the problem, writing patents and developing software.
Rather than trying to solve the ultimate answer to the universal
question -- which we all now know is "42" -- I concentrated on
alleviating HPTC data management queuing issues. Compared to general
purpose HPC applications, all high performance throughput processing
applications bear similar data transport characteristics for which it
is possible to remove queuing bottlenecks by taking advantage of
locality of reference principles.
So, what unique space do we fill in the Grid computing market? Without
question, we fill the urgent need for clever data management tools to
remove the data transport bottlenecks plaguing all Grid computing HPTC
Our company name, eXludus, is Latin for "Stop playing."
Gt: In July, the company received $1.5 million in seed financing
that was earmarked to help with technology development. How is the
development coming along, and when can we expect to see the first
MARCHAND: Well, the $1.5 million was not earmarked solely for
technology development. As I said earlier, I have started to work on
development back in 2002 and until early 2005 I was self financing all
activities. The product was well underway when we closed this round of
financing. Consequently, nearly three quarters of our operation cost is
devoted to market development and sales activities. This is rare among
By the end of September, we will release our first two products with two more products coming out within two quarters.
Gt: Speaking of products, tell me about RepliCator, eXludus's data management software?
MARCHAND: RepliCator does what its name says: replicate data. But it also does a lot more.
Data replication simply means that all Grid processing nodes receive
the same data simultaneously. This removes the need to send, resend and
re-resend, etc., the same data over and over again to each requesting
processing node. Indeed, it is typical that throughput processing
applications share an input data set. This is one source of data
transport queuing, a bottleneck that we eliminate by sharing the
network connection while data is sent.
RepliCator also caches data at each processing node. Caching removes
another source of data transport queuing where the same data set -- or
portion thereof -- is reused several times by a series of jobs in
throughput applications. Moreover, caching linearly increases data
access bandwidth. It takes an expensive file server/disk farm/network
infrastructure to sustain data transfer rates of 1 GBps to feed 10 MBps
to each of 100 nodes, but the same 100 nodes have an aggregate 100 GBps
data bandwidth (assuming a Gigabit network), and it's free!
RepliCator also does data staging. So, while a processing node is busy
computing on Job "B," we fill the data cache with the data set needed
for Job "C" and in the background retrieve the results for Job "A,"
which completed earlier. This way, processing nodes are kept busy at
all times. The trick is to perform data staging efficiently. Our
footprint is less than 2MB of memory and an average of 1 percent of
The RepliCator product suite also performs data activated processing.
This innovative feature permits the automatic synchronization of data
transport and job dispatch activities. Until now, everyone has been
dispatching jobs and then waiting for data (data transport queuing).
This was fine for supercomputers and large SMPs with direct attached
storage, but large clusters and Grids have exposed the limitations of
the process-centric scheduling approach. With RepliCator, the transport
of data triggers the dispatch of jobs, so processing nodes don't wait.
RepliCator is fault tolerant "+". Not only does it handle network and
node failures automatically, but it also performs recovery
automatically. So, upon return to normal operation, processing nodes
complete the transfers they missed.
These features are unique among data management tools currently
available and that's just the beginning. I can promise you amazing
surprises not too far away.
So, what's the bottom line to all these features? Our aim is to
demonstrate a positive ROI to every one of our customers. We recover
much of the processing capacity wasted by data transport queuing and
reduce the cost of support infrastructure while simplifying system
I told you before. I believe in technology as a means to improve the way we work and we live. Don't come to us for gadgets.
Gt: I understand you have a vision of "aesthetic and efficient
design" that has not only found its way into your software design, but
also in the office environment. Can you speak a little about this
vision and why it's important that it is so pervasive within the
MARCHAND: Efficiency in software development is core to our
company. Beyond the patents and other trade secrets, we derive much of
our competitive edge and protection against copycats by having
developed an innovative and efficient way to develop networking
By contrast, most software development happening nowadays is limited to
"reusing" modules and tools developed by others in the past. They
derive new functionalities by building on top of something else.
Consequently, most software stacks have become expensive and
unmanageable Babel Towers.
Only by thinking differently and developing technology "out of the box" can one expect to create truly innovative products.
Moreover, software design is an act of creativity. How can anyone
expect software "artists" to be creative when their working environment
looks like a dentist's office or worse, as I've seen, is in the
basement of an old office building in the suburbs? In business schools
strategists talk about business coherence. Well, in our case coherence
starts with aesthetics. We put our developers in a cozy loft in old
Montreal -- near the port, restaurants and commuting facilities. We
provide them with the most silent desktops we could find, remove all
walls and replace them with glass so light floods everywhere and,
finally, give each of them a handmade solid maple wood desk designed by
a local artist. The environment becomes a constant reminder of our
design efficiency goal and a challenge to excel at being creative.
It works. We've completed two products in six months with two more
coming up within the next six. And our technology surpasses everything
else in complexity and features.
The amazing part is that by using local artists and carefully selecting
the office, we've kept cost down to the same price as if we had gone to
the suburbs, rented a basement and furnished it with chain store
Gt: Can you discuss the company's concept of "economic reality?"
How does this concept relate to off-shoring, a practice that seems to
be picking up steam with each passing day?
MARCHAND: I come from a small town in Quebec, lost in the
mountains near the Vermont border. Out there, one goes to Fred -- who
owns the local garage -- to get his car fixed, and to Julie, the local
pharmacy owner, to buy nose drops. We know that a local community may
only survive through local patrons and that we're all interdependent.
It used to be that North America derived most of its economic power
from its production capacity. In the name of globalization, a lot of
that has been shipped overseas. "Fine," we said, "we can maintain our
economic status through our service economy." Well, with off-shoring
we're soon about to lose our edge in this sector, too. So, what will be
left for North America? Lumber, grain, water, fisheries, and some oil
and gas in Alaska and Canada?
After we've shipped our economic-power-generating industries elsewhere,
how will the economy grow worldwide if there's no one left in North
America able to buy goods? For instance, the U.S. may be a $12 trillion
economy, but already $700 billion per year is wasted in the trade
deficit, and it's expected to grow to $1.5 trillion in the next few
years. When a nation's trade deficit growth rate exceeds its GNP growth
rate, there's a problem. But when it becomes an acceptable long-term
economic modus operandi, that's looking for trouble!
I strongly believe in three things. First, unrestrained global economy
may only lead to global catastrophe. Second, it is immoral to take in
money from customers in a region and not to reinvest most of it in that
part of the world. Third, it is also immoral to benefit from abundance
and not share with those less fortunate.
I get offers to offshore our R&D every week. Well, we're located in
North America because this is where we intend to do most of our
business for now. When we grow significant business in Europe, we'll
invest in Europe, too. And when we will have reasons to invest in Asia,
we'll do it without hesitation. This position, however, does not
preclude providing support to those in need. Our company charter states
that when we are in a position to do so, we shall find ways to support
less fortunate economies through technology transfer programs,
If every CEO of every North American technology company gives in to the
lure of easy and quick profit, we'll do the same to our economy as we
did to the environment. So our children -- I have three -- will be out
of clean water and out of jobs.
Personally, I have found some ways to maintain a profitable software
development operation in North America, including the Canadian R&D
tax credit program and some other Government incentive programs and
management practices. Yes it's more work, but it's the right thing to
Gt: Wow. I'd love to delve deeper into that, but we must move
on. I noticed that Wolfgang Gentzsch, a name GRIDtoday readers
certainly recognize, sits on the company's Board of Directors. What is
your relationship with Wolfgang, and how did he end up on the Board?
MARCHAND: Dr. Gentzsch is certainly a respected figure in the
Grid Computing community and every start-up company would welcome such
a prestigious name on their board of directors -- we certainly do. He
brings in unparalleled technical expertise, market visibility and
However, Wolfgang is much more than that to us. He is a contagious
motivator. He is an honest and moral person whose perspective on
business and people we share. Stephen Perrenod -- our VP of sales and
marketing -- Wolfgang and I were all working at Sun Microsystems,
evangelizing HPC and Grid computing together. We may have not always
agreed, but we learned to respect and trust each other. We share the
same passion and values. Besides, Wolfgang believes in our technology
and business experience.
Gt: Looking into the future, how do you see eXludus growing
within the next couple of years? Where do you see the company being
five or 10 years out?
MARCHAND: In the next couple of years, we envision eXludus to
develop more innovative products to solve Grid computing data
management problems, and there are plenty, I assure you. While we are
currently concentrating on technical Grid applications, such as
seismic, finance, genomics, etc., we expect to go into commercial Grid
applications as well, certainly within the next two years. Our
technology bears undeniable advantages in data base and Web
Looking further away, we are already planning an OEM technology
division. Indeed, our technology is, at the core, based on innovative
telecommunication principles that are well suited to a wide variety of
I hope to maintain our focus as a software design company. Our business
model is to design innovative software technologies and introduce them
to the market. Growing large sales, customer service and consulting
practices is not our plan. History tells us that innovative start-ups,
when they grow that way, get into a state of sclerosis. My hope is to
keep eXludus a start-up like business for as long as possible.
Gt: Finally, along the same line, how do you see Grid, and even cluster, technology evolving within the same timeframe?
MARCHAND: Pervasive processing, I believe, is the trend of the
future. I think everyone agrees by now -- it was not so obvious in 2002
when I started -- that telecom and processing technologies are
converging. This pervasiveness will undeniably accelerate acceptance of
Grid computing, be it in the cluster, edge or world wide form.
Ultimately, one's processing needs, whatever scale they might be, will
be addressed nearly in real-time by hordes of next-generation
PDA/cell/desktop/TV/Web browser/e-mail/portable entertainment devices.
Sounds far fetched for you? Well, if 10 years ago I would have
predicted that today you'd carry all of your personal music collection
in a package size smaller than a lighter for less than $200 you would
have probably laughed. iPods are already pervasive.
Gt: That's a good point. Is there anything else you'd like to add?
MARCHAND: I am very thankful to have had the opportunity to
represent eXludus Technologies to GRIDtoday, as well as being given a
chance to express myself on more general and personal points of view. I
imagine that my points of view on economic correctness and short term
maximization of profits may shock a few people. I'm sorry about that
and do not intend to offend anyone. However, I believe things change
and that it's about time North America wakes up and adapts.
