MPICH是MPI的重要研究,提供了一系列的接口函数,为并行计算的实现提供了编程环境.

In order to run this code, one must have Java 1.1.6 or above.

Directory Structure
--------- ---------

In the jumpshot-3 directory, we have the following subdirectories:

bin/       contains the actual jumpshot wrappers

doc/       contains various jumpshot documentations

lib/       contains jumpshot's setup files and various jar's for the GUI

logfiles/  contains the sample slogfiles

src/       contains the actual JAVA codes for the GUI

swing/     contains the swing library needed to build Jumpshot if you
           are using JDK 1.1.x.



Jumpshot Installation
-------- ------------

In order to build Jumpshot, we need to build four jar files and some
wrapper scripts.  This can be achieved simply by doing the following:

        cd $(JUMPSHOT-3)
        ./configure --with-java=<Your_JAVA_full_pathname>
        make

Where "--with-java=<Your_JAVA_full_pathname>" is optional.  It is necessary
only when configure cannot find a good version of JDK in the typical
java location.   The procedure listed above is for the case when the 
source and installed files are put in the same directory.  The more 
elaborated procedure is to do a VPATH build like the following:

       cd $(build_dir)
       ./configure --with-java=<Your_JAVA_full_pathname> --prefix=<install_dir>
       make
       make install

Or     

       cd $(build_dir)
       ./configure --with-java=<Your_JAVA_full_pathname>
       make
       make install PREFIX=<install_dir>

For further details of configure, do "./configure --help"
After "make install", "make uninstall" will remove all installed files.
        
Note: ignore the warning messages during compilation of jumpshot.jar.

In AIX, be sure the "java -fullversion" return a build data later than 
or equal to "JDK 1.1.6 IBM build a116-19990115 (JIT enabled: jitc)"



Running Jumpshot as An Application
------- -------- -- -- -----------

There are 2 ways to run jumpshot-3.

1, using the supplied script in $(JUMPSHOT-3)/bin:
   cd to $(JUMPSHOT-3)/bin and run Jumpshot by entering "jumpshot" or
   "jumpshot slog_filename", e.g.

   /homes/chan/jumpshot-3> bin/jumpshot [logfiles/merge.slog]

   With a filename as the command line argument, jumpshot skips the 
   logfile selection process and starts reading the file immediately.

   Set the CLASSPATH in your local shell to where slog.jar, jumpshot.jar
   and swing.jar, preview.jar and statsviewer.jar are located.  Check
   $(JUMPSHOT-3)/bin/jumpshot for exact syntax.  Then you can invoke 
   jumpshot-3 as

   java MainFrame [slog_filename]


1, run jumpshot directly using "java" or "jre".
   change directory to the jumpshot-3 build directory to build
   "executable"( only meaningful to Java 2 SDK ) jar file, jumpshot3.jar.

   cd <jumpshot-3_build_dir>
   make exejar

   If Java 2 SDK or JRE is used, jumpshot-3 can simply be invoked as

   java -jar jumpshot3.jar MainFrame [slog_filename]

   [slog_filename] is optional.
   If Java 1 SDK or JRE is used, it is a bit complicated to launch it.
   It invokes sets up CLASSPATH.

   cd <jumpshot-3_build_dir>
   setenv CLASSPATH `pwd`/swing/swing.jar:`pwd`/jumpshot3.jar:.
   java MainFrame [slog_filename]




Running Jumpshot in Client-Server mode
------- -------- -- ------------- ----

Here assume Java 2 SDK, i.e. jdk-1.2.2 or newer, is used.
The SLOG server code has only been fully tested using Java 2 SDK.
Using Java 1 SDK to launch SLOG server would be more complicated,
i.e. one has to set the CLASSPATH explicitly.  The server code
has NOT been tested with Java 1 SDK.

When running Jumpshot-3 in client-server mode, the client is
an applet which has to be launched from a Java 2 enabled web-brower
or appletviewer.  The distribution comes with jumpshot3.html file
which can be used to invoke the applet.  One can put jumpshot3.html
and jumpshot3.jar( created by "make exejar" at the top-level directory )
into your user html directory.

cd <jumpshot-3_build_dir>
make exejar
cp jumpshot3.html jumpshot3.jar lib/slog.jar ~<my_username>/public_html

Before invoking the applet, the SLOG RMI server needs to be launched
first by doing the following.

cd ~<my_username>/public_html
java -jar slog.jar -l -m <server_hostname> &

Here <server_hostname> can be `hostname`.

Here assume the http server and slog server will be the same machine.
where "-l" option enables logging of all the activities of the server.
For more usage information of the SLOG RMI Server, do
"java -jar slog.jar -h".

To invoke the client, say on machine <client_hostname>
appletviewer http://<server_hostname>/~<my_username>/jumpshot3.html



Running SLOG RMI server with a security manager
------- ---- --- ------ ---- - -------- -------

cd ~<my_username>/public_html
java -Djava.security.manager -Djava.security.policy=slogd.policy
     -jar slog.jar -l <slogd_logging_filename> -m <server_hostname> &

the file slogd.policy has the following lines

grant {
  permission java.net.SocketPermission "<server_hostname>", "accept, connect, listen, resolve";
  permission java.io.FilePermission "<slogd_logging_filename>", "write, read";
  permission java.io.FilePermission "logfiles/*", "read";
};
