[mpich-discuss] Errors while testing MPICH2 on Vista

[mpich-discuss] Errors while testing MPICH2 on Vista

I am trying to test a fresh installation of MPICH2 (version 1.2) on Vista32
and get the following errors:

c:\temp>"c:\Program Files\MPICH2\bin\mpiexec.exe" -n 4 cpi.exe
Please specify an authentication passphrase for smpd: <*I type here the
passphrase, e.g. behappy*>
Error while connecting to host, No connection could be made because the
target machine actively refused it. (10061)
Connect on sock (host=user-PC, port=8676) failed, exhaused all end points
Unable to connect to 'user-PC:8676',
sock error: Error = -1

I will appreciate any comment.

IGT HPC WG Meeting

The next IGT HPC Work Group meeting

14:00-16:30, November 4th , 2009 IGT Office Maskit 4 Hertzeliya


14:00-14:15 Welcome talk Avner and Guy

14:15-15:15 Mr. Lior Amar and Mr. Tal Maoz – Clusterlogic: CLiP & Infod -- HPC Cluster Management and Monitoring

15:15-15:30 Coffee break

15:30-16:30 Mr. Nadav Rotem, Haifa University - Introduction to Reconfigurable Computing



CLiP & Infod -- HPC Cluster Management and Monitoring
Mr. Lior Amar and Mr. Tal Maoz
ClusterLogic (
) specializes in providing advanced solutions for HPC Linux clusters. In this talk we will present two of our products, aimed at making the task of cluster management and monitoring easier:

CLiP is a Cluster Installation and Management system which enables the rapid installation of diskless (and diskfull) clients. It is very flexible and enables the administrator to setup multiple desired configuration with only a few clicks.
The client nodes boot using the desired configuration and in a few minutes the cluster is ready for use.

In this talk we will perform a live demonstration of CLiP.


Infod is a gossip based information dissemination system, designed to give a robust cluster-wide information exchange platform. Nodes running this system routinely exchange information with other (randomly selected) nodes in the cluster. The outcome is that each node maintains a partial (or full) view of the cluster. This view can be used for
load balancing or monitoring and is constantly updated.

In the talk we will present the concepts behind the system and a live demonstration of the system will be performed.

Introduction to Reconfigurable Computing

Mr. Nadav Rotem, Haifa University


Reconfigurable computing is a paradigm which combines the flexibility of software with the high performance of hardware. Recently we see more and more FPGAs in High Performance Computing. Problems which were previously solved by either software or custom hardware machines are now done by hybrid reconfigurable systems. In this talk I will introduce FPGAs, present their architecture, their programming tools and design process. I will present commercial hybrid systems which combine reconfigurable components with traditional clusters. I will present High-Level Synthesis, which is a method for programming reconfigurable devices using high languages such as C. I will present several reconfigurable applications and compare their performance with traditional cluster implementations.
