Hi!
I am trying to run NAMD 2.9 on multiple nodes of SDSC Trestles. It runs
fine on all 32 cores of the same node. However, if more than 1 node is
specified I get the error message:
mpiexec_trestles-3-17.local: cannot connect to local mpd
(/tmp/mpd2.console_gianluca); possible causes:
1. no mpd is running on this host
2. an mpd is running but was started without a "console" (-n option)
In case 1, you can start an mpd on this host with:
mpd &
and you will be able to run jobs just on this host.
I e-mailed the administrators for help and I got the following answer:
"did you compile with the mvapich_ib mpi stack?"
I tried then to compile charm++ with:
./build charm++ net-linux-x86_64 ibverbs iccstatic --mvapich_ib
--no-build-shared --with-production
But I get the warning messages:
./bin/charmc --mvapich_ib --no-build-shared --with-production -c -I.
pipelinestrategy.C
icpc: command line warning #10006: ignoring unknown option '-fmvapich_ib'
icpc: command line warning #10006: ignoring unknown option
'-fno-build-shared'
icpc: command line warning #10006: ignoring unknown option
'-fwith-production'
and I am still not able to run on multiple nodes.
Any help would be appreciated,
Thanks,
Gianluca
