Hello. I am not sure if this is the correct list to ask this question, so if you know of a more appropriate one please let me know.
I think am looking for a LiveCD that supports MPI, specifically one that has mpif90 built in, and can easily mount external (USB) drives for storing data. I have access to 40 Windows computers in a lab that rarely gets used. I would like to use the computers to run a cluster during the weekends, but be able to not mess with the Windows installation that exists on the hard drive. Because of this, I think a LiveCD would be good, and one that supports PXE booting is even better. If there is a better way to do this (run MPI, not disrupt Windows) please let me know. The applications that I want to run are originally written in Fortran90 and have been ported to MPI (by me) and compile with mpif90. I have attempted to use ParallelKnoppix and PelicanHPC (see below) and have spoken to the author of the distro, but he isn't explicitly supporting mpif90. >From the list at http://www.knoppix.net/wiki/Cluster_Live_CD I have tried many distros. Below are the results of my attempts with the LiveCDs: BCCD 2.2.1c7 [DHCP server, ssh "heartbeats"]: http://bccd.cs.uni.edu/ mpiexec "command not found" mpirun -np 1 ./a.out : "cannot execute binary file" mpif90: "no fortran 90 compiler specified when mpif90 was created" gfortran: "command not found" PelicanHPC (Debian) [DHCP server, PXE boot]: http://pareto.uab.es/mcreel/PelicanHPC/ mpirun works mpiexec works gfortran works mpif90: "command not found" ParallelKnoppix 2.9 (Knoppix) [DHCP server, PXE boot]: http://idea.uab.es/mcreel/ParallelKnoppix/ mpirun -np 1 ./a.out : "cannot execute binary file mpiexec -np 1 ./a.out : "cannot execute binary file", "mpirun failed with exit status 252" gfortran works mpif90: "command not found" ifort: "command not found" lamexec -np 1 ./a.out : "cannot execute binary file Note: mounting external drives is most intuitive in PK ClusterKnoppix: OpenMOSIX (no MPI) http://clusterknoppix.sw.be/ CHAOS: OpenMOSIX (no MPI) Pai Pix: could not find on internet Thanks for your help, Ben
