Pardiso OOC supports the extended set of matrices which can be solved on IA32

Sun, 08 Nov 2009 22:36:16 -0800

The problem:
Recently we received multiple inputs from our customers regarding 32bit Pardiso Out-of-Core (OOC) solver crashes when solving a big task.
These failures are related to the fact that the memory needed for numerical factorization stage, one of Pardiso stages, exceeded 2Gb. 2 Gb roughly corresponds to the memory allocated at the factorization stage for 250*10^6 double nonzero elements of L factors.

Solution:
The latest version of Intel® MKL 10.2 Update 2 introduces the advanced option allowing solving such tasks for the real symmetric positive definite matrices ( mtype == 2 ).
The solution for the other types of matrices will be implemented in the next versions.

Below example (Laplace3D.cpp) shows how such problem can be solved on ia32 system, It uses OOC "PARDISO" routine for a symmetric positive linear system with one right hand side.

Compile and link the example with MKL 10.2 Update 2 and run with the following input arguments:

test.exe n1 n2 n3

where,
n1, n2 and n3 are the dimensions of Laplace3D matrices.
The number of solved equations is be calculated as n1 * n2 * n3

For example,
with the command line
test.exe 140 140 100

The number of equations is equal 1.96*10^6 and so it requires 1.96 * 10 ^ 9 nonzero elements on the factorization stage. Such task can be solved on the system with RAM = 2 Gb and the available physical memory 1.2 Gb (at the moment when the task starts ).
Important to mention that MKL_PARDISO_OOC_MAX_CORE_SIZE environment variable was set 1000 Mb.

Remain limitations:

Let us note that 32bit Pardiso OOC solver cannot solves problems with more than 2 000*10^6 double nonzero elements of L factors, because of 32bit counters inside 32-bit PARDISO.

Pardiso will returns something like:
*** Error in PARDISO (32-bit overflow problem.) error_num= -182
*** error PARDISO: reordering, symb. Factorization

Developer Ignite

Thanks to everyone who came out to the event!
It was a fantastic success!

Watch a short video from the event!

Download a PDF with all Developer Ignite presentations (12 MB)

Watch the full-length presentations from the event in seven parts:
Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, and Part 7

Developer Ignite is an information exchange event for software developers to connect and share topics that are of interest to them. Since this is a technical event, topics will be centered on relevant and important information to software developers. For more information on Ignite, please take a look at the O'Reilly Ignite site.

Presentations:

Barry Stahl: Simplicity Through Abstraction
The goal of this presentation is to explore, at a very high level, one methodology for software developers and architects to create software that is simple and maintainable, and thus has a lower total-cost-of-ownership (TCO).

Ben Atkin: jQuery Plugin Development
I would like to tell people how to develop a neat and useful jQuery plugin. It will likely be some type of widget. I think it will benefit the development community by encouraging people to explore jQuery and JavaScript and see more of their potential.

Bill Mar: Beagleboard and Spark Community Projects
My presentation is "Beagleboard and Spark Community Projects" to tell the story of how the Beagleboard community project got started and how I and some other people got Microsoft Windows Embedded into the act with free tools for the hobbyist/startup community.

Bret Feddern: What You Don't Know About ColdFusion Will Knock You on Your A$$
Most of the Developers and Companies I come across are Ruby on Rails, or PHP, or .NET, and they use WordPress, Joomla, or SharePoint, etc. Few know the true potential behind ColdFusion and what CF has to offer. With my 5 minutes, I will give an overview of just how awesome CF is and why other developers in the area should be more open to it.

Brian Shaler: Physical Computing With Arduino
As a software developer with no background in electrical engineering, physical computing was always a little out of my reach. Thanks to Arduino -- the exciting open source hardware-firmware-software platform -- the barrier to entry for software developers has been lowered significantly. Within minutes, you can be interacting with real world inputs (sensors) and outputs (LEDs, servos, etc).

Chris Chandler: Cryptography
We use RSA and AES all the time, but what makes them tick? What are the other options? Why should we care? The storage, transmission, and management of sensitive data usually requires that it is enciphered. This is a 5 minute presentation on cryptographic algorithms and key management.

Evo Terra: Get Out of Your Cube!
In the last 3 years, Phoenix has seen the creation and expansion of several community-based social groups and activities that are "developer-friendly". Real people getting together in real life to talk, drink, listen, learn and generally have loads of fun. These formal and informal "meetups" take place all over the valley and each have their own charm. In this talk, I'll talk about many and point you into the direction where you can find more!

remi Taylor: You're Doing it Wrong!
You're doing it wrong and you should be ashamed of yourself! If you're not testing your code, your clients should fire you. If you're not test-driving your code, your co-workers should set you on fire!

Saul Mora: CSS3 + HTML5 = Awesome
CSS + HTML is how the web works. Let's go over, not just the cool features of CSS3 + HTML5, but why they will be awesome for future web development.

Scott Cate: Version Numbering your Software
Version Numbering your software. Does this even matter? Are version numbers used more than just to later identify what version a file is? Well in our world it matters deeply. We'll spend five minutes talking about how source control, an automated build environment, and an integrated version "labeler" can better your software management process.

Event Address:
Gangplank
325 E Elliot Rd, Suite 34
Chandler, AZ 85225 | Map it

Developer Ignite will always be free to both presenters and attendees. This event is sponsored by the Intel Software Network, a community where developers can learn about and engage in topics that are relevant to their career, professional development and hobbies. The venue is provided by Gangplank, a co-working environment for web professionals. If there is something you don't like about the way Developer Ignite works, and want to change it, please let us know. We'll listen, but can't promise to accommodate every request.

ld: symbol(s) not found when linking library containing no executable functions

Thu, 05 Nov 2009 17:45:51 -0800

Reference Number : dpd200045548

Version : 10.1, 11.0, 11.1

Product : Intel Fortran Compiler

Operating System : Mac OS X

Problem Description : If a library built with ar contains objects with Fortran module data but no executable functions, the symbols corresponding to the module data may not be resolved when an object referencing them is linked against the library. The symbols are present: the compiler generates a common symbol (C), e.g.
0000000000000050 C _module_modname_mp_varname_
but the linker does not realize that it needs to link the corresponding object.

Resolution Status : This issue may be fixed in a future version of the compiler.
It may be worked around by adding -fno-common to the compiler (not linker) options. This will cause symbols such as the above to be placed in the text section instead of the common section, and the linker will then pick them up.

Intel Cloud Builder program launched

Thu, 05 Nov 2009 14:45:02 -0800

For those of you implementing the infrastructure of a cloud, often called IaaS or Infrastructure as a Service, one of the challenges can be “where to start?”. With the myriad of hw options and variety of software solutions finding a starting point can be daunting.

For example:

· What server configurations are optimal?

· How to structure the network?

· What is the optimal storage configuration?

· I really don't want to write this software , therefore, what is the cloud management stack that best suits my needs?

Assuming that cost reduction and/or agility are the reasons you are building a cloud (true for the vast majority of customers), then there is huge benefit from using a largely homogenous architecture: identical server, network, storage, and management configurations across the cloud implementation. This architecture addresses the maintenance aspects of the infrastructure (remove from service if it fails, replace when enough are out of service to justify a visit to the data center) as well as the operational aspect (no special cases). Getting to the point where workloads can be hosted in this environment requires effort but has a fairly quick payback once you complete the transition.

Even with this in mind, you still have to design the hardware infrastructure and then select a set of management tools.

Intel recognizes this need and has formed the Intel Cloud Builder program to help in this ‘getting started’ phase. If you are already well down the road to building a cloud, you will likely find the output from this program useful to understand the options available in the market.

Intel(r) Cloud Builder is a fairly simple program with a powerful output:

* using a defined hardware blueprint,

* using a cloud management software stack,

* run the combination on a Intel hosted cloud test bed,

* and document the results.

Contest Champions

Tommy Refenes, First place winner of Best Threaded Game in the 2008 Game Demo Contest is was born June 14th, 1981 in Hendersonville, North Carolina. At the age of 11, Tommy's parents bought him a "laptop" which weighed about 30lbs and it was on this computer Tommy started coding in QBasic and became interested in developing games. Throughout high school, Tommy took a few classes in Pascal and C++, which further grew his interest in programming. While attending NC State, Tommy took contract jobs for a few large .com companies and eventually left the university early to pursue a career in software development. After holding a few web and sever development jobs, Tommy decided to sell his house and car and move to the Netherlands to start work at a company as an Xbox 360 engine programmer. In May 2006 Tommy moved back to the US, founded PillowFort and begin work on Goo!, his winning entry in the contest.
