Hardware Performance Counters ; Power measurement

I have a 4-node Intel Nehalem cluster and a 512 core Intel Clovertown cluster. I am interested in looking for some tools to measure the power consumed by parallel applications. I know that we can use external devices to measure and log power consumption. I would like to know if someone around here has some experience with any particular tool-kit. I would greatly appreciate it if someone can point me in the right direction.

Using new unified installer for Cluster Tools 3.2.2 - Slow

I downloaded the new cluster toolkit 3.2.2.

Little 128 node cluster with master node.

The install scipt installs the rpms onto the master node.
Then it is taking quite awhile to 'Analyze node configuration'
Watching it's progress: It's taken 46 minutes to process 23 nodes.
I'm guessing the installer is attempting to discern network topology, or if any compute nodes share the install directory.
Though, when prompted by the installer, I selected 'non-shared' install, i.e. /opt/intel is local on each compute node.

Running mpi w/o mpiexec/mpirun

I can compile and run a mpi application using mpiexec without any difficulties.
What I want to do is to run a mpi application not in Terminal,I mean without using mpiexec or mpirun.
Is this doable? If it is, how can I setup mpd daemon and other necessary stuffs in source level?

Problems installing cluster toolkit under windows server 2008

Hi all,

during the installation of Cluster Toolkit for Windows HPC Server 2008 I had some "noncritical errors":

An error occured in Merge Module SUBST.
Installation will be continued but NOT all of the following files will be configured appropriately:

C:\Program Files (x86)\Intel\ICTCE\\Compiler\bin\ifortvars.bat


After installing Cluster Tookit I have checked build environment with the following output:

.nsfxxxx files generated at execution with mpi


When I use my software running with Intel MPI 2.0 (sorry can't update MPI for the moment), I can see numerous temporary files named .nfsXXXXXXXX which worried my customers . The process running with MPI needs 4 files in input and generates4 files in output, all these files are read and written on a remote disk via the network and the I use 4 cpus.
Can you tell me more about these files, is there a relationship between the number of .nsfxxx files and the files in input/output?
