- (project add text here)
+ 2011-April Tashi Incubator Status Report
+ Tashi has been incubating since September 2008.
+ The Tashi project aims to build a software infrastructure for cloud computing 
+ on massive internet-scale datasets (what we call Big Data). The idea is to 
+ build a cluster management system that enables the Big Data that are stored in 
+ a cluster/data center to be accessed, shared, manipulated, and computed on by 
+ remote users in a convenient, efficient, and safe manner.
+ Tashi has previously encompassed just the tools to manage virtual
+ machines using Xen and KVM, but is gaining the facility to hand out
+ physical machines as well.
+ Development activities have included:-
+         * Importing bug fixes from CMU deployment
+         * Don't display exceptions if failure is expected
+         * Validate fields and clean invalid instance entries
+         * Eliminating inconsistent state between node and cluster manager
+         * Allow hosts to be soft powered off via ACPI
+         * Refactor primitive scheduler to be less convoluted (ongoing)
+         * Define a stable branch for tested code
+         * Example support for dynamic scratch space disks
+         * Enforce designated copy-on-write data filesystem for Qemu
+ The project is still working toward building a larger user and development 
+ community. User groups have been identified in Ireland, Slovenia and Korea,
+ as well as at Georgia Tech. CMU usage is growing as other groups hear about
+ the availability of the resource. Intel has restructured its research
+ division and folded some operations into adjoining academic sites. 
+ Items to be resolved before graduation:
+         * A stable branch exists which could be a release candidate, but
+           the codebase is large and test hardware is currently in
+           short supply. We are confident that the code in the stablefix
+           branch will work if running QEMU emulation, Pickle or sqlite
+           data storage, primitive scheduler. Xen, other data stores and
+           schedulers have not been tested recently.
+         * Scratch space integration would be desirable, accounting
+           integration is probably a necessity
+         * Develop community diversity (Committers currently at Telefonica,
+           Google and CMU)
