 HPL Benchmark on my laptop It's the Top500 season time. I therefore tested HPL on my laptop using Intel's latest OneAPI version 2021.1.10.2261. The laptop specifications are obtained from lscpu : $ lscpu Architecture:                    x86_64 CPU op-mode(s):                  32-bit, 64-bit Byte Order:                      Little Endian Address sizes:                   39 bits physical, 48 bits virtual CPU(s):                          8 On-line CPU(s) list:     ...

Forget about LINPACK and FLOP/s. It is the skin that matters. The next big thing should be the "Top500 Skin" ranking. Here are my top five:       Corollaries: 1. As can be seen the US maintains its dominance. 2. All vendors can try harder. How about consulting Italian car designers? 3. SC20 should take place at the Museum of Modern Art.

RaspberryPi , a $35 toy or the next disruptive technology and a possible building block for HPC ? This credit card sized board has a ARM11 processor and 512MB RAM. The board is powered via a micro USB connector. It has two built-in USB sockets, Ethernet and HDMI video. A schematic drawing of model B which I have can be found here . I installed  Raspbian  Linux, an optimized Debian version for Raspberry, on a 4GB SD card. A cool gadget for triggering thoughts about the future of computing. Enclosed below a few pictures I took, enjoy!

The slides of my talk at the  HPC Advisory Council Israel Supercomputing Conference 2012 that took place on February 7th, 2012 at Tel-Aviv university are available from here . The Importance of High-Performance and High-Throughput Computing in Israel

About four years ago I predicted in this blog the fall of Grid Computing and the rise of Cloud Computing (  http://telzur.blogspot.com/2007/10/end-of-grid-computing.html  ) Now I want to claim that Supercomputers as we know them today will not be the kind we will see in the future. I think that within a couple of years: 1. Most supercomputers will shift to the cloud (HPC Cloud). 2. The governance of X86 is not guaranteed: We already see the rise of GPGPUs and we will see more families of technologies being involved, e.g. Tegra and ARM, Reconfigureable Computing (RC) i.e. FPGAs, etc'. 3. Supercomputers won't be anymore General Purpose machines. They will be reconstructed as a Cloud Service ( Supercomputing as a Service ) from all the available technologies (see previous section) per single mission (program) in order to maximize the performance and minimize the consumed energy and cost. I decided to use the word mission because the word  task is u...

In this post I will show step by step how to install and execute MPI (Message Passing Interface) parallel programs in the .NET environment. A much more detailed tutorial is available here . 1) Installation: My computer is running Windows Vista and Visual Studio 2008 is already installed. Download and install the HPC Pack 2008 (next 5 figures): Then install the MPI.NET SDK.msi (see next 4 figures): 2) Test the installation from the command line (next 3 figures): A "Ping-Pong" program Serial run: As should be, the firewall detects the communication traffic and the user should allow it: Parallel run: 3) MPI "Hello" demo using Visual Studio 2008 and C# (next 5 figures): Start a new console C# project: Add Reference to the MPI component: Build the executable: Execute the parallel program with 8 threads: Verifying the execution of the 8 threads by looking at the Task Manager: That's all for now. Your comments are welcome. Guy Tel-Zur Email: tel-zur@computer.org

- Intel® Parallel Software Tools for HPC and Multi-Core Computing - Erlang for 5 nines Monday, December 8 th , 2008 IGT Offices, Maskit 4, 5th Floor, Hertzliya. 14:00-14:15: OPENING - Avner & Guy 14:15-15:00: Intel® Parallel Software Tools for HPC and Multi-Core Computing Herbert Cornelius, Director Advanced Computing Center EMEA and Alexander Supalov, Engineering Manager Intel Cluster Tools Abstract As we see Moore 's Law still continuing, more and more parallelism is introduced to all computing platforms and on all levels of integration and programming. Especially in the area of High-Performance Computing (HPC) users can entertain a combination of different hardware and software parallel architectures and programming environments. Those technologies range from vectorization and SIMD computation over shared memory multi-threading (e.g. OpenMP) to distributed memory message passing (e.g. MPI) on cluster systems. But it also puts more and more demand on software...

Last week I attendded the HP-Cast 10 conference which took place in Singapore. At the conference, as a delegate of the Israeli Association of Grid Technologies , I gave an overview presentation about Grid Computing in Israel. The presentation PDF file is available here .

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 ...
