This is to re-announce the availability of MPICH for T3D.
Our announcement from April 18 is apparently still stuck
in review by moderators of comp.parallel.  So, here is
a post just to the more relevant groups:

We noticed that in the meantime, EPCC has posted their
software availability.  We hope our announcement on  comp.parallel
makes it through review eventually.  Our announcement is quite
old news already.

Thanks,
Tony Skjellum

ftp this software from ftp://aurora.cs.msstate.edu/pub/Message-Passing/mpich_t3d.tar.Z
This si the temporary location.  It will be integrated with MPICH in future.


 
		 MPI for the Cray T3D Release Notice
	      (MPICH with Cray T3D Shared Memory Driver)
			  Alpha Version 0.1a
                       
                             April 19, 1995
 
We are happy to announce alpha release 0.1a of the MPICH on the Cray
T3D.  Previously, only a subset of the MPI specification existed on
the T3D using the native message passing software T3DPVM.  This
new technology offers a more complete implemenation of the MPI
standard and is expected to offer substantially higher performance.
 
MPICH, the model implementation of MPI, is a joint research effort
project between Argonne (Bill Gropp and Rusty Lusk) and Mississippi
State (Tony Skjellum and Nathan Doss).   MPICH is the most widely used
public implementation of MPI.  For more information on MPICH, please
see http://www.info.mcs.anl.gov/mpi/ or http://www.erc.msstate.edu/mpi/.
 
Current status of the Cray T3D implementation (as of April 19, 1995):
 
1.  Most MPI functions are supported.  The only functions known not
    to work are MPI_Rsend, MPI_Irsend, MPI_Ssend, and MPI_Issend.

2.  The current limit on the number of processes is 256. 
 
3.  There are quite a few known optimizations that have not yet been 
    done.  The main goal of this initial release is to provide a
    functional, working version of MPI.  
 
4.  The code has not been thoroughly or systematically tested.
 
5.  This software is not yet part of the standard MPICH release,
    and will not be until it has been tested and upgraded further.
 
6.  Optimization of collective operations remains to be done.
 
Note: We will work quickly to remove these limitations.
