SGI Native	3.0	X	X
ORNL PVM	3.3	-	X

1.2 Using PVM

• SGI Native PVM:A native (vendor-supported) version of PVM (a port of PVM 3.3.9) is available in the /usr/array/PVM directory. Both 32- and 64-bit versions are available. The libraries are in /usr/lib32 and /usr/lib64 respectively. Relevant man pages are pvm_intro, pvm and pvmd.

  The PVM daemons (pvm and pvmd3) for native PVM are available in /usr/array/PVM/lib/arch. The relevant arch are:

  • SGIMP64 : default
    Compilation flags = -mips4 -64
  • SGIMP32mips4 : 32bit binaries
    Compilation flags = -mips4 -n32
  You may want to consider using this version over the ORNL version because it contains many performance enhancements.

  To compile and link:

  -I/usr/array/PVM/include -lpvm

  See /usr/local/doc/lsf/samples/pvm.sample for a sample batch job that compiles, links, and runs a PVM job.

• ORNL PVM:The Oak Ridge National Laboratory version of PVM 3.3 is installed in the /usr/local/apps/pvm3 directory.

  To compile and link:

  -I/usr/local/apps/math/pvm3/include -L/usr/local/apps/math/pvm3/lib -lpvm

2. Documentation

The following online resources are available for PVM:

• The PVM home page at www.epm.ornl.gov/pvm/pvm_home.html contains documentation and FAQ's about PVM. Also included is a hypertext version of PVM: Parallel Virtual Machine, A Users' Guide and Tutorial for Networked Parallel Computing [Geist et al, (1994) MIT Press].

• The SGI manual Message Passing Toolkit: PVM Programmer's Manual for SGI's implementation of PVM.
