MicroGrid- Emulation Tools
for Computational Grid Research
Installation
MicroGrid is free software, see
copyright notice at the end of this page for copying permission.
After downloading the file (mgrid2.4.6.1.tgz), you'll need to unzip it and
untar it using gzip(gunzip) and tar. For example,
tar -zxvf mgrid2.4.6.1.tgz
Check out the MicroGrid User Guide (PDF format) file for further instructions on how to
compile and install the system.
Some required supporting packages can be
found here.
Notes:
The MicroGrid is an experiment toolkit as
our research effort. We have been trying
to make it stable and easy to use.
However, some minor problems have been found and are to be fixed:
- Version 2.4.6 (released on Dec 12, 2004)
- Version 2.4.5 (released on May 10, 2004)
- Version 2.4.4 (released on Feb 23, 2004)
- The emulator crashes occasionally due to some unknown error. This happens in our experiments with probability about 5%. - Version 2.4.3 (released on Feb 1, 2004)
- The CPU Controller has a serious bug which may cause application to suspend. This bug has been fixed in version 2.4.4.
If you find any other problems, please email
to mgrid@csag.ucsd.edu. Thanks!
