Release Notes: Added dvt and rvt, to allow multiple interactive xterms tied to a single input window. Added jsh/jsd, a job scheduling daemon intended to be used for parallel compiling. Lots of bugfixes and speedups in the code.

Other releases

Release Notes: A new program, dtop, allows the user to run top across multiple machines and collate the results in real-time. The default remote commands have been changed over to ssh from rsh. A test option has been added to all commands to check if SSH is up and running before attempting an SSH connection that might otherwise hang. A flag has been added to dsh allowing the user to copy, execute, and delete a script on all machines in one step. There are many other small bugfixes and enhancements.

Release Notes: A -b option was added to pcp. This adds the ability to reverse the operation of pcp and use it to gather files from remote machines. A -t option that performs a port-is-active test on each node before running the commands on those nodes was added. The default RCMD's was switched from rsh to ssh. The RCMD_CMD and parsing of similar settings was changed to allow the user to set RCMD_CMD to something like "ssh -v" and have it work properly. dtop, a distributed top command was added.

Release Notes: Fixes jsd to work properly on Linux. Adds a -v option to all programs to show what version of ClusterIt they are running. Replaces most instances of sprintf with snprintf. Replaces most instances of malloc with calloc. Adds RCMD_CMD_ARGS to most of the programs. This makes it easier to do things like run "ssh -4" as your RCMD_CMD. Fixes a bug where trailing whitespace on a GROUP or LUMP entry would cause dsh -g to not match it. Fixes a bug where Linux machines often recieved truncated output from the child ssh/rsh process. Fixes a bug where all the programs would mangle argv[0] for ps.
