Grid-HPC WG Meeting

June 28th, 14:00-16:00 - Grid-HPC Work Group meeting

Location: IGT Offices, Maskit 4, 5th Floor, Hertzliya


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



Jacques Philouze, Vice President Sales & Marketing, Allinea

As two, four and potentially eight-core processors become the norm, the defacto HPC architecture is tending towards large clusters of modest 8-16 core shared-memory servers, potentially with co-processing devices (eg. GPGPUs, FPGAs, Clearspeed). Programming these machines optimally presents a number of challenges, and applications that use a mixed programming models are now becoming commonplace.
In this presentation we will discuss the challenges facing today's HPC application developers, and the need for simple tools that can address mixed programming models. We will present new multicore features of Allinea's Distributed Debugging Tool (DDT) and Optimisation and Profiling Tool (OPT), and discuss our aims to provide a consolidated, scalable, yet intuitive framework for HPC developers .

14:50-15:00: BREAK


FastDL - Cluster Computing with IDL

Timely Visualization and Analysis of Large Data Sets Using IDL and Parallel Computing


Arie Rubin M.Sc.E.E.

IIT-Image Information Technologies (Represents ITT VIS, Boulder Colorado USA)


Scientists exploring fluid and particle dynamics, high-energy and plasma physics, astrophysics and space sciences, biophysics, protein folding and medical science are challenged to visualize and analyze increasingly complex data. With FastDL scientists and developers can run IDL visualization and analyses applications in parallel on cost-effective Linux clusters, significantly shortening the time required to get results. FastDL is comprised of two independent components that address the varying needs of parallel data analysis and visualization applications: TaskDL and mpiDL.TaskDL allows users to run IDL procedures on multiple machines simultaneously by collecting different remote processors together as a task farm. mpiDL provides a Message Passing Interface (MPI) within IDL for synchronizing and passing data between nodes during program execution. GRIDL – Grid Computing with IDL Running parallel IDL applications on a set of nodes communicating over WAN.

How to convert data cd/dvd back into an iso file?

Very simple:
type "df" to find the dvd file system name, then:

dd if=/dev/dvd_fs of=mydvd.iso

That's it!

How To Install VMware Server On A Fedora 7 Desktop | HowtoForge - Linux Howtos and Tutorials

VMware on Fedora-7 (F7)

I found the following reference useful when I installed VMware:
How To Install VMware Server On A Fedora 7 Desktop | HowtoForge - Linux Howtos and Tutorials
However, there still was a problem: After defining a new virtual machine I got this error message:

"Unable to change virtual machine power state. The "/usr/lib/vmware/bin/vmware-vmx" process did not start properly...."

Any ideas what to do next????

Later addition:
I think this is because the latest VMware is not ready yet for the advanced F7 and its latest kernel.
What it did was to fall back to CentOS5.
