Current PVFS2 status
PVFS2 Development Team
Last Updated: September 2003
This document describes the current status of PVFS2 development. This document
only includes issues related to functionality or correctness. No
performance optimizations are listed for now.
This section lists file system limitations for which we have a known
solution or plan.
- efficient conversion of MPI datatypes to PVFS2 datatypes in ROMIO
- hooks for tuning consistency semantics
- hooks for controlling distribution and distribution parameters
- standardizing error code format
- integration of user level buffer cache
- eliminating memory leaks
- consistent error handling in client and server state machines
- simple failover plan
These are features that are implemented but have not been thoroughly tested.
- GM network support
- IB network support
These parts of the code have a working implementation, but we intend to
replace them as time permits.
- ``contig'' request encoder implementation
- pvfs2-client implementation
The items on this list are known problems that have not been resolved.
- access control / security
- how to manage client side configuration (fstab information)
- support for 2.4 series kernels
- how to add file systems to an existing system interface run time instance (proper vfs bootstrapping)
- managing server configuration files
- nonblocking I/O at system interface
- how to handle I/O failures, unposting, etc.
- TCP module scalability
- extended attributes
- redundancy
This section points out specific areas of the code that demonstrate
best practice for PVFS2 development.
