re: Compaq launches Open SSI Cluster Projects

Bruce,

I have just read your paper at

http://bjbrew.org/cpq/ssic_linux/montreal/sld001.htm

and in particular the summary page at

http://bjbrew.org/cpq/ssic_linux/montreal/sld053.htm

I must say that I am blown away with what you are doing.  

Once your goals are accomplished, it looks to me as if you will have the most advanced UNIX level HA/HPC clustering solution available.(I am including the commercial products like TruClusters and Veritas.  I don't know enough about Beowulf or Mosix to comment.)

Would you agree with that?

Without fully understanding the pros/cons, I hope you are successful in garnering interest for getting this into the standard Linux Kernel.  (Unfortunately, I am not a player in the Linux world so my support won't mean anything.)

The one negative I see is that you seem to have been developing this in a vacuum from the Linux communities perspective.

The only Linux technology I see in the presentation is GFS.

Are there any other pre-existing Linux HA/HP cluster technologies you are incorporating?

 >>  We will put the CVS repository on the web when we can.

 >>  Open Single System Image (SSI) Clusters for Linux Project
 >>  The Open SSI project leverages both Compaq's NonStop
 >>  Clusters for Unixware technology and other open source
 >>  technology to provide a full, highly available SSI
 >>  environment for Linux.  Goals for SSI Clusters include

 >>  and DLM, single process space and process migration, load
 >>  leveling, availability monitors and failover, single namespace  
 >>  and shared access for all forms of IPC, devices and networking, 
 >>  and a single management space.  The SSI project will leverage 
 >>  the Cluster Infrastructure for Linux project.
 >>  Source beyond the CI base is not yet available.  We are
