Beowulf
Cluster "Bat Cave" and "Wayne Manor"
This
8 node Beowulf Cluster at UWM is maintained by Dr.
B. Wade and Chris Sears of the Numerical Analysis Group, and is used for testing
of various parallel algorithms for scientific computing research as well
as student seminar projects. Projects to date have
typically involved Domain Decomposition algorithm development for
Partial Differential Equations as well as parallel training of
artificial neural networks.
Bat
Cave contains 8 1 GHZ Pentium III processor nodes, each with 256 MRAM and 20
GB Hard Drive, and Red Hat Linux 6.2 is the operating system. The
nodes are connected through 100 MB/S speed Ethernet protocol.
It has
Lahey
Fortran 95 and Gnu gcc (egcs 1.1.2) under MPICH 1.2.4. Also, GSL,
PetSci and Gnuplot are employed.
The
4 node
Beowulf Cluster called "Wayne Manor," shown at right, at UWM is maintained by Dr.
B. Wade and Chris Sears of the Numerical Analysis Group, and is used for
debugging purposes in testing
of various parallel algorithms for scientific computing research as well
as student seminar projects.
Wayne
Manor contains 4 900 MHZ Pentium III processor nodes in two dual
CPU Dell boxes, each box with 512 MRAM and 20
GB Hard Drive. Red Hat Linux 6.2 is the operating system. The
boxes are connected through 100 MB/S speed Ethernet protocol, while the
two CPUs in each box share memory.
These
names have been chosen based on a Batman theme. The slower cluster used
for first run debugging is called Wayne Manor because it is the first
entrance to "Bruce Wayne's" place, while the Bat Cave is where
the real work is done, i.e., final testing runs for the purpose of
timing.
Due
to several experiences with hackers, each OS is heavily cut down to the
essentials and very high security has been put in
place.
These
two clusters (12 machines) are housed in an ordinary faculty office with
only one fan sending air into the space above the false ceiling. The room temperature tends to
hover about 80 degrees F.
