We are working on the Texas persistent store, a persistent store that does pointer swizzling at page fault time, to efficiently suppport huge address spaces on standard hardware. Addresses are resolved to native virtual-memory addresses when a page of data is brought into the address space of a processor---subsequent accesses incur zero address translation overhead. This technique can be used to support shared address spaces across networks of heterogeneous machines, which may have different hardware address sizes. On machines with large hardware addresses, the swizzling can be optimized away. The swizzling facility is still useful for resolving conflicting address mappings across large networks, and for backward compatibility with 32-bit machines. (Published papers and source code for Texas are available via anonymous ftp from cs.utexas.edu. See the README file in the directory pub/garbage.) We are also working on garbage collection techniques that we will eventually apply to persistent and distributed data. wilson@cs.utexas.edu (Paul R. Wilson) svkakkad@cs.utexas.edu (Sheetal V.
