"rpvm" is an R package providing interface to PVM (Parallel Virtual Machine).

=============================================================================
DEPENDENCE
=============================================================================
rpvm depends on R version 1.8.0 or higher and PVM 3.4.3. Optionally rsprng.
=============================================================================
INSTALLATION:
=============================================================================
1. Install pvm 3.4.3 (http://www.netlib.org/pvm3/pvm.3.4.3.tgz) and set
environment variable PVM_ROOT to the directory pvm is installed.
See pvm documentation for details.
Binary distributions of pvm are available for some platforms (rpm for
Redhat Linux, deb for Debian GNU/Linux, etc.).
You need install pvm for each host you want to include in the virtual
machine.
2. Install rpvm
R INSTALL rpvm_version.tgz.
You need install rpvm for each host.
If PVM_ROOT is not set, the configure script will try to look for
first /usr/lib/pvm3/ then $HOME/pvm3/ and stop if none exists.
3. Install slaveR.sh
You need copy the script 'slaveR.sh' (under $R_LIBS/rpvm) to somewhere
pvmd can find on each host. The easiest way is:
cp $R_LIBS/rpvm/slaveR.sh $PVM_ROOT/bin/$PVM_ARCH
4. Try run 'demo (helloR)' in R.
=============================================================================
TEST:
=============================================================================
The examples in the Rd files are "dummy" examples in that
R CMD check rpvm
won't actually run those examples. However, there are two scripts in tests
dir which should run successfully if pvm has been installed properly.
Caveat: To be able to run the test successfully, the local host shouldn't be
part of a already running VM (since rpvm may not be installed on other hosts).
After the test, pvmd is left running on the local host (attempts to shut down
the VM with .PVM.halt() in the test R script will abruptly shutdown R itself
and resulted in error exit).
