Revision History
Changes In DOGMA 0.8
-
MPIJ - MPIJ has undergone large improvements in its implementation, documentation,
and ease of use. Versions prior to 0.8 have a very simple MPI implemtation
which was for exploratory purposes. Starting with DOGMA 0.8, MPIJ
is working towards a full MPI implementation with a large amount of MPI
functionality implemented.
-
Dynamic object group support is now added. This allows master-slave
parallel applications to be written very easily. These applications
are ideal for taking advantage of users who donate their CPU cycles by
browsing into the DOGMA system or by using the DOGMA Screen Saver.
Changes In DOGMA 0.7.1
-
Output from nodes can now be redirected. This eliminates the need
to actually go to the node to view output or to view node output outside
of DOGMA. The redirection is flexible and allows output to either
be sent live over the net, or stored locally on each node where it can
be retrieved.
-
Unix is now supported.
-
GUICon is now known as SysCon. The command to start it is now startSysCon.
-
The system panel command prompt now stores a command history, and displays
currently executing commands as well as which nodes they are executing
on.
-
Fast MPIJ messaging will now correctly send from an object to itself without
actually using the net.
Changes In DOGMA 0.7
-
A simple HTTP server is now included in the distribution. This server is
capable of redirecting requests to other HTTP servers as needed by browser-based
nodes to load classes from multiple codebases.
-
The DOGMA screen saver has been added to allow idle nodes to automatically
donate idle cpu cycles to DOGMA.
Changes In DOGMA 0.6
-
Installation - DOGMA 0.6 is the first release to feature simplified installation
and uninstallation.
-
Browser participation
-
Faster MPIJ messaging for MPI.Send() and MPI.Recv() for float[] and double[]
(~85 Mbps on Fast Ethernet for large messages).
