Public Hardware
Pinto infiniband cluster
The pinto cluster can be used both for software development and production runs, via LSF batch.
Software
MPI
- OpenMPI with Ethernet and Infiniband
The goal is to move away from all previously mentioned MPI versions and switch
to this one. It will have support for all the different interconnect used at
SLAC. It will be available as 32 bit and 64 bit version.
We currently support only RedHat's OpenMPI, which is version 1.4 on RHEL5.
If the mpi executables (mpirun, mpic++, etc.) are not in your PATH, you may need to run
mpi-selector-menu. Generally, you should select "openmpi-1.4-gcc-x86_64"
unless you have some reason to use the 32-bit version. See also the man page.
Various compilers are available. We generally recommend the latest Intel compilers for
MPI work. You can add them to your PATH by sourcing the following script (assuming csh/tcsh
and 64-bits):
source /afs/slac/package/intel_tools/2011u8/bin/compilervars.csh intel64
- MPI for Mac OS X
We currently do not support any MPI versions for Mac OS X.
Click here for a little SLAC specific MPI tutorial.
OpenMP
We do not currently have any expertise to support OpenMP. It is reported to work with
the Intel compilers. Here
is an old OpenMP Tutorial.
Mixed MPI and OpenMP Programs
It is possible to use OpenMP inside an MPI program.
Here is another old SLAC specific tutorial
on how to do this.
Debugger
- The GNU debugger
gdb is available in your search path on all
SLAC machines.
- The Intel debugger is
idb. See the man page.
- Totalview
SLAC has 1 (one) license for up to 4 CPUs.
The debugger is avialable for Linux only.
It is accessable via /usr/local/bin/totalview or
/afs/slac.stanford.edu/package/totalview/toolworks/totalview.7.0.0-1/bin/totalview
It is available for 32-bit or 64-bit.
