We now have a apt-get repository for OpenSSI on Debian. apt-get install openssi will get you a complete single system image cluster. I have tested it on a 9 node cluster. Check this out

Fixed lot of bugs with OpenSSI on Debian. Also tested Debian OpenSSI cluster on a 3 node cluster. You can download the packages from here

Lots of debian update w.r.t e2fsprogs and util-linux. Also modified some of the openssi commands so that they now work as expected for debian. All the changes needed for commands to support fail-over cluster are now in debian. I don't have the hardware to test a failover cluster. I guess some script level changes may be needed to get it working.
Send Richard Henderson a small patch with respect to Alpha.I guess it is not yet in the main tree. Need to check with him whether i should send it to the lkml.
Wrote a document explaing how to install OpenSSI on debian . You can find it here

Started looking at OpenSSI changes for 2.6 kernel. I guess this is going to take time. OpenSSI modifies many base kernel files. But it is a good learning.

Moving all the CI changes to 2.6.1 . GNU arch is talking a lot of time to generate diffs. I am thinking of moving back to cvs. I will use the same branching that Brian is using right now for 2.4 tree .

Last few days was busy with the debian support of OpenSSI. The project is getting ready for a 1.0 release.You should be able to download the debian packages from here

I also managed to tag the CVS with arch-Alpha-kernel tag so that one can checkout a 2.4.18 based OpenSSI kernel that support HP Alpha architecture from the CVS using this tag. I verified this source using HP testdrive machines

Today I got the CI repository completely built with 2.6 source. Now the bug hunting starts.... ;-)

Today I got cluster/clms compiled, but with some #ifdef .I also moved all the timeval struct to timespec. I guess 2.6 count time using timespec. ( see xtime and current_kernel_time() ) . Also I noted that the source in the CI repository is broken and it can't build CI alone. Any how I am not going to fix that.

Finished merging the CI repository( Not yet started building it fully ). I have moved files around and renamed some function. I am looking for getting CI in three changeset
1) Build changes
2) Changes to base Linux kernel files
3) Changes( new files ) added for CI.
That way others should be able to review it better.

BTW this is a good revision control system

Yesterday had a nice time in boston. Went to the boston common . There were amazing ice sculptures. Then went to see fireworks at boston harbor. This site was helpful www.firstnight.org Well yesterday I enjoyed the day. I was feeling more or less the same as how i used to be in bangalore ;-). I guess i need to spend time going around places.

On OpenSSI side Finished fork and signal related changes. Commited the same to the local repository. Struggling with alpha assembly again( ret_from_rproc ) is fun ;-).
