I will continue to post here, but may tweet more often. Micro blog may just work better for me. My tweets…

Interesting Comment by Neelesh Gupta

HPC, Just the facts, Trends No Comments »

Neelesh is my childhood friend. We recently got connected after some 20 years – thanks to Web2.0… To my last post “High Perfromance Computing – not the same anymore”, he made a very interesting comment and it cannot stay tucked inside the comment corner of my blog but be up here for everyone to read. Neelesh is now based in NY and works for Citibank as Vice President (I can now guess VP for what?).

Thanks Neelesh!

====================================

Uttam,

Its interesting you mention about CUDA and the advent of GPU based computing.

This is something most of the high-end investment banking houses here in NYC and also in the UK are seriously looking at. We currently use symphony based grid orchestration for lot of our compute power needs for various risk calculations (monte-carlo simulations, prepayment modeling and fixed income risk calculations).

But now several teams are trying to evaluate moving to GPU based computing. My initial reactions to this was that GPU based computing is good if you are doing a “pure-maathematical-grind” type of calculations rather than something that requires an “if-else” type structured logic. Well that does not come to me as a surprise as GPUs were primarily built for that kind of stuff – image rendering or graphics type programming, where matrix algebra is the cornerstone for all computations.

What we were a little hesitant as part of our evaluation and future possible adoption was that someone using CUDA is sort of married to the architecture and its hard to unplug out of it. Most of the code logic in CUDA world is very intrusive and not platform agnostic. Might not be a big issue but this is something software engineers are usually cautious about. (P.S: we were looking at the NVIDIA based products).

But on the flip side there is huge-huge cost savings in hardware needs and data center needs. We were amazed by the amount of reduction we would have in h/w if we ever redid all of our code using the CUDA based API.

While this space is sure to evolve in the very near future in terms of compute power needs, I also have a strong suspicion that the likes of Intel/AMD will try to put something in place in their architectures to prevent or limit folks from leveraging the massive GPU power or at least make sure that they are somehow the part of the equation. At the end of the day the “instruction-set” or the brain power still is with the main CPU and they (Intel/AMD) could tweak things around…

Cheers!!

High Performance Computing – not same anymore

Customers, HPC, Just the facts, Trends 2 Comments »

Scientific and Enterprise computing that are CPU intensive is not going to be same anymore. GPU architectures are making those large G/T/P FLOP systems faster, greener and smaller, also cheaper.

More and more applications are getting accelerated with CUDA. Among good examples are – CFD solvers running at 1/20 of resource for a given iteration; HMMER running at 62x time faster; Monte Carlo Simulations running up to 50x time faster.

The GPU architectures from CUDA and FireStream have already made it to Top500 list sometime ago which has been a milestone and is fast moving up the charts, I am sure the 35th list of Top500 is going have much more of GPU+CPU. It is only matter of time that desktops would be replaced with supercomputers. The GPU’s help offloading non-sequential parts of application from the CPU and achieves performance of nature described before.

More interesting to watch is if CUDA is really breaking the dominance of Intel and AMD? And if more and more developers will optimize applications with OpenCL or DirectX for CUDA? What will even happen to ClearSpeed?

Cheers!

Business Technology Summit

Locuz - SOI & SOM, Locuz way - SIM/CMDB/IDM, Trends No Comments »

Here too my paper got selected and am speaking at the Bangalore event.

The topic is same as the one I spoke at INTEROP but this time around, I will touch base on “Service Orientation for the Enterprise Cloud”. You may wonder, cloud is all about service orientation anyway so what would SOC (my musings on SOx, after SOI & SOM) – Service Oriented Cloud – be about.

As cloud definitions and perspectives evolve, we found our way to explain what goes within and beyond.

See you at the BT Summit.

Cheers!

Security & SOA (Event at Bangalore)

Customers, Events, Locuz - SOI & SOM, Locuz way - SIM/CMDB/IDM No Comments »

We are organising an event on 20-Aug-2009. The event will cover Security framework in the service-oriented economy.

You will hear from us about the “critical shift” with IdM and Access Management in today’s environment that is brought on by increased service standards, improved systems and business agility.

If SOA is the way to go, understanding the “critical shift” may be equally important.

Here is the invitation.

Go thru the program details, and do register if you wish to attend.

Cheers!

INTEROP in India

Events, Locuz - SOI & SOM, Locuz way - SIM/CMDB/IDM, News, Trends No Comments »

The paper I presented got approved and I have confirmed to speak.

Hopefully the first INTEROP in India will match the scale and popularity it is identified with.

If you are visiting, ping me, I will be happy to meet.

Cheers!

Unified Computing

Just the facts, Locuz - SOI & SOM No Comments »

Since I could not create one for our way of SOI/SOM, I borrowed this one and is the closest we are to. This is something I otherwise keep saying with product neutralism; however would never mind using Cisco technology in our stack to SOI. Go thru by pressing the replay button…

Cheers!

SOI = “Unified Computing”

Events, Locuz - SOI & SOM, News, Trends No Comments »

Next week Cisco would announce their Unified Computing strategy codenamed “California”. These are blade servers that would sit right in middle of the Data Centre unlike all other Cisco products that found place in the network closet.

This in good sense is SOI we wanted to achieve and were seeking product maturity for levels of automation it would demand.

In our definition of SOI Orchestration is most vital and hopefully would soon be available across all Data Centre components. I am upbeat about the Cisco announcement.

Unified Computing = SOI, if I may conclude.

Cheers!

Testimonial – Locuz RIM

It is matter of immense responsibility and pride for all of us at Locuz. Sanjeev should be credited with the fact that his decision then helps Samit stay healthy thru tough times like these.

RIM & Recession

Just the facts, RIM 1 Comment »

Every single meeting I had in the last two months – that I did not post anything on my blog – was about IT heads saying they have their eyes fixed on the ball – doing more or same but certainly with less.

Remote Infrastructure Management is the surest way. But this can be misleading too. It is extremely important to know what capabilities one should look for in the RIM partner. Let me offer a few tips (not in any order and none being optional) -

1. RIM partner should be able to offer flexible models
2. Should have deep Network and Systems Integration skills
3. Be specialized in Security
4. Contribute in transformational projects for Business IT alignment
5. Offer best practices and have delivery Centre Certified
6. Introduce Automation and Standardization – processes and delivery
7. Should be able to co-locate systems closest to the Delivery team
8. Virtual staff augmentation of highest quality
9. Contribute to Architecture decisions
10. Innovate (and can mean so much)
11. Tools – best of breed
12. Improving Datacentre efficiency for power and space
13. Consolidate and optimize the network, systems and storage
14. Mitigate all risks connected with Business Services availability
15. Finally bring cost down by 20% in the first year

Our customers have chosen us for these reasons.

Conclusion – RIM Services is the way forward to better manage IT Infrastructure while reducing operational costs.

I will have a note from a customer who is keen to share the experience on my next post.

Cheers!

Uttam
