Invitation to the next IGT HPC Work group meeting

Monday, March 26th, 2007
IGT Offices, Maskit 4, 5th Floor, Hertzliya


Agenda:


14:00-14:15: OPENING - Avner & Guy


14:15-14:50: PPF, JAVA, OPEN-SOURCE AND GRID: BEYOND THE TRADITIONAL GRID
Speaker: Laurent Cohen, ILOG, Inc. and JPPF founder
Abstract:
Traditional Grid architectures rely on a concept of job submission that comes with a set of constraints regarding the nature of the compute nodes, the ease of deployment of the jobs, and the effort required to use the Grid, which could otherwise be utilized to work on the problems to solve. JPPF offers an alternative, enabling a true heterogeneous nature of the Grid components, an ease of use that permits engineers, developers and scientists to focus on their domain rather than on the grid infrastructure, while retaining the benefits of the Grid technology to solve heavy and complex computational problems.We will present how the design and architectural choices in JPPF, in terms of programming language, installation, administration, dynamic configuration, updates automation, application code deployment and security policy automation, bring outstanding benefits in the areas of the cost of adoption, level of effort at the operational and organizational levels, as well as the resulting ease of use for the end-users.


14:50-15:00: BREAK


15:00-15:35: INTERACTIVE, USER FRIENDLY, PARALLEL COMPUTING ON CLUSTERS
 Speaker: Yoel Jacobsen/E&M CTO
Abstract:
Productivity boost brought by Star-P to the teams of MATLAB-skilled domain experts is matched by the economic benefits of getting the most out of the computing power of next generation servers and clusters. Star-P enables interactive workflow for large-scale scientific and engineering computing, eliminating the need for intermediate steps of reprogramming the code in C, Fortran, and MPI, and dramatically shortening the time to insight.


15:35-15:45: DISCUSSION AND CONCLUDING REMARKS

The End of Grid Computing?

-

In the year 2003 the MIT Technology review ranked "Grid Computing" among the 10 Emerging Technologies That Will Change the World [1]. We are now four years later and something is not going well with "Grid Computing". An indication that there is a problem can easily be seen by looking at the "Google Trends" plot for the term "Grid Computing": (click on the image to get the current trend). This finding can be compared with another buzz word, "Virtualization", which is older than "Grid Computing" and yet is gaining more and more momentum: There is however one exception. The Academic Grid is still having lot's of glory thanks to the huge heavily funded European (EGEE) and other US projects. When LHC data will start to be taken at CERN it will reach it's top importance. But, it seems that for other scientific projects Grid Computing is not going to be such a success. It will remain as "Nice to have" but will never...

Parallel Debugging with a Serial Debugger

Parallel Debuggers are important tools when trying to eliminate bugs in parallel programs. Commercial parallel debuggers are expensive. In this blog post I will show you a free and open source alternative which is good enough for education purposes and for small codes. Suppose you want to debug the famous cpi.c code which computes an approximation to pi by a parallel numerical integration. This demo uses the free Data Display Debugger (ddd) which is based on gdb but has a nice GUI. Step 1, compile: mpicc -g -o cpi ./cpi.c Step 2, run (without a debugger): mpirun -np 2 ./cpi Step 3, run with the free Data Display Debugger (ddd) : mpirun -np 2 ddd ./cpi The last command will open two MPI processes (instances) of ddd each running cpi, see screen capture: Finally, I enclose here a short video which I hope is convincing: hi-res version:  https://youtu.be/N_J4NKJkuMs Happy (Free) MPI debugging!
