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 ...

This note describes establishing VPN connection between my laptop and my remote Linux server. I was inspired by the first example in " Casting Your Net with OpenVPN " by Paul Duncan article that was published in the Linux Magazine. First I created configuration files at both ends, see screen dump for the client configure file: Then I started OpenVPN on both computers: and similarly at the remote server: After establishing the connection, I could connect via my private network: I did SSH from my client (10.55.55.2) to my server (10.55.55.1):

The 4th Grid-HPC Work group meeting Date: Thursday, November 9th Location: IGT Offices, Maskit 4, 5th Floor, Hertzliya Agenda: 14:00 - 14:15: Opening. Avner & Guy 14:15 - 15:00: Grid Mathematica. Speaker: Haim Ricas, M.Sc Applied Mathematica General Manager Tashtit Scientific Consultants Ltd Wolfram Research Distributors in Israel Abstract: gridMathematica implements many parallel programming primitives and includes high-level commands for parallel execution of matrix operations, plotting, and other functions. It comes with sample applications of many popular new programming approaches, such as parallel Monte Carlo simulation, visualization, searching, and optimization. The implementations for all high-level parallel processing commands are provided in Mathematica source form, so they can also serve as templates for users to build their own parallel programs. At the meeting I'll present a general overview, I'll demonstrate powerful...

I just installed Fedora Core 6. The WiFi was not detected (once again :( ). Here are the steps to overcome this problem: 1) Find the type of card installed on your laptop by lspci -v : 0c:00.0 Network controller: Broadcom Corporation Dell Wireless 1390 WLAN Mini-PCI Card (rev 01) Subsystem: Dell Unknown device 0007 Flags: bus master, fast devsel, latency 0, IRQ 177 Memory at dfdfc000 (32-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 2 Capabilities: [58] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- Capabilities: [d0] Express Legacy Endpoint IRQ 0 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel 2) Download and install the latest ndiswrapper (ndiswrapper-1.27.tar in my case) # cd ndiswrapper-1.27 # make uninstall # make # make install # lspci -n [root@localhost DRIVER]# ndiswrapper -h install/manage Windows drivers for ndiswrapper usage: ndiswrapper OPTION -i inffile install driver described by ...
