9.7 Notes for Rocks Users
Rocks does not include LAM/MPI or
HDF5 but does include several different MPICH releases, located in
/opt. MPE is included as part of Rocks with each
release. The MPE libraries are included with the MPICH libraries,
e.g., /opt/mpich/gnu/lib. Rocks includes the
jumpshot3 script as well, e.g.,
/opt/mpich/gnu/share/jumpshot-3/bin for MPICH.
(Rocks also includes upshot.)By default, Rocks does not include Java. There is, however, a Java
roll for Rocks. To use jumpshot3,
you'll need to install the appropriate version of
Java. You can look in the jumpshot3 script to
see what it expects. You should see something like the following near
the top of the file:...
JAVA_HOME=/usr/java/j2sdk1.4.2_02
...
JVM=/usr/java/j2sdk1.4.2_02/bin/java
... You can either install j2sdk1.4.2-02 in
/usr/java or you can edit these lines to match
your Java installation. For example, if you install the Java package
described in the last section, you might change these lines toJAVA_HOME=/usr/local/src/j2sdk1.3.1
JVM=/usr/local/src/j2sdk1.3.1/bin/java Adjust the path according to your needs. |
