1 Test con MPIch-G2 Roberto Alfieri - Fabio Spataro WP1 meeting January 11, 2001 Gruppo Collegato di Parma

2 Parma The Installation:

3 MPICH: our rpm packages (ftp://ftp.pr.infn.it./pub/linux/rpm/contrib/) mpich-1.2.1-2.i386.rpm (-with-device=ch_p4) mpich-smp-1.2.1-2.i386.rpm (-with-device=ch_p4 -comm=shared) mpich-G2 -1.2.1-2.i386.rpm (-with-device=globus2) mpich-G2-smp -1.2.1-2.i386.rpm (-with-device=globus2 -comm=shared) Parma

4 TESTS PLAN Test Tool: Perftest (http://www-unix.mcs.anl.gov/mpi/mpptest/)http://www-unix.mcs.anl.gov/mpi/mpptest/ mpptest (point-to-point communication performance) goptest (collective communication performance) Rete_Mpi (Neural Network Training - our MPI benchmark ) LAN Tests: mpptest on SMP using mpich mpich-smp mpichg2 mpichg2-smp mpptest on TCP using mpich and mpichg2 goptest janus(2)-janus1(2)-janus2(2) using mpich and mpichg2 WAN Tests (Parma - Padova): Processes distribution: mpptest, RETE_MPI Remote submitting Parma
