Hi All,

Well, the long-awaited new optimized version of XPVM 1.1 is out.

Woo-Hoo!

The new XPVM is MUCH faster than the old 1.0.3 version, and includes
several new view features.  The new XPVM is also compatible with
EITHER version of TCL/TK, as settable with a compile flag.  (The 
install procedure for the source distribution is a bit simpler now,
too!)

XPVM 1.1 is available on Netlib, as usual, by:

	anonymous ftp to netlib2.cs.utk.edu

or via the Web at:

	http://www.netlib.org/pvm3/xpvm/index.html

Please don't hesitate to send along bug reports and install problems
to me at "kohl@msr.epm.ornl.gov".  I usually respond within the hour
and I'll either fix your problem or put out a patch ASAP.

I already know of a couple minor bugs in 1.1.0, so it won't be long
for 1.1.1.  Get your bug reports in soon so they'll make the next
patch!  :-)

Thanks & Enjoy!

	Jim

==================================================================

New XPVM 1.1 View Features Overview:

	* Enhanced Network View:  now animates the network volume
		and bandwidth on the links connecting hosts.  The
		color is the volume & the thickness is the bandwidth.

	* Optimized Utilization View:  no longer second guesses on
		future events, only fills in states with known end
		times to avoid recursively re-drawing a gazillion
		times.

	* New Message Queue View:  visualizes the number and size of
		messages which are waiting to be received for each
		task, shown as stacks of rectangles.  (Note, the
		size of messages at send time is not known in PVM
		3.3 tracing, so for now the message sizes are fixed
		and settable using the "-M size" command line option.
		This will be fixed in PVM 3.4's new tracing facility.)

	* Automatic Help Messages:  when you move the mouse pointer
		over a button or label, the main status message will
		temporarily flash up a line of text describing what
		will happen if you click on what you're pointing at.

	* Double Clicking:  you can now double-click on those pesky
		Space-Time and Message Queue items, and then move
		the mouse pointer back and forth over the event call
		text to read the entire line.  :-)

	* BUTT FASTER:  much of the interpreted TCL / TK has been
		converted to faster C code.  Woo-Hoo!
