diff --git a/INSTALL.parallel b/INSTALL.parallel new file mode 100644 index 0000000..278d4f3 --- /dev/null +++ b/INSTALL.parallel @@ -0,0 +1,28 @@ +This file contains instructions for the installation a version of HDF5 +that uses the parallel file I/O facilities of the MPI-IO library. A +parallel version of HDF5 can run in a serial environment as long as +the appropriate MPI-IO and MPI header files and libraries are +available. + +The parallel version of hdf5 can be build by generally following the +instructions in the INSTALL file for building a serial version and +using `mpicc' as the C compiler. This can be done by setting the CC +environment variable before invoking configure as with: + + $ CC=mpicc ./configure + +If the mpicc compiler is not available then a parallel library can +still be built as long as the appropriate header files and libraries +can be found. If these files are part of the default compiler search +paths then configuration is as simple as: + + $ ./configure --enable-parallel + +Otherwise, if the MPI and MPI-IO header files or library cannot be +found then the compiler search paths can be corrected, the files can +be moved, or configure can be told about the file locations. The +latter is done with something like: + + $ CPPFLAGS=-I/usr/local/mpi/include \ + LDFLAGS=-L/usr/local/mpi/lib/LINUX/ch_p4 \ + ./configure --enable-parallel |
