Netmem is a client-server software that manages chunks of memory in a transactional way. The server allocates memory and then listens on a socket for the client, which can use these pieces of memory (through read, lock, and unlock operations). It is useful for cluster applications that need a quickly accessible shared space of memory across the network.
Myosotis allows MySQL and PostgreSQL clients to connect directly to the Sequoia cluster or any other database with a JDBC connector. From the client application's point of view, Myosotis acts as a MySQL or a PostgreSQL server. It's like a proxy, and it sits between the client and the database server.
The MyCAT project is a toolset for managing MySQL/Linux servers, and could be helpful for anyone managing a network of *nix servers whether running MySQL Cluster, standard replication, or not running MySQL at all. At present, it contains three programs. rcall eases use and administration of groups (clusters) of *nix servers by creating logical groupings and a single location from which to run commands on all servers while entering it only once. It requires only an SSH connection. rep_mon is a replication monitor that notifies if a server is lagging or has encountered any errors. It handles any replication topology easily. binlog_mon monitors disk space used by MySQL binary logs, purging only when disk space is needed. It checks all slaves to ensure that purged files are not still being read by slaves. It has configurable behavior in the event that a slave still needs the oldest file.
esky is an implementation of job freezing (checkpoint/resume) for Unix processes. It can save the state of a running process to disk then later resume it from the point it left off, possibly on a different machine. esky currently works on a limited but non-trivial range of processes. esky can cope with programs that open or mmap() files, including opening shared libraries with dlopen(). esky is implemented entirely in userspace - no kernel patches or modules are required. It works under Linux 2.2 and Solaris 2.6 and is written to be independent of CPU type.
The Password Storage and Retrieval (PSR) system is a supplement to OpenPBS that allows PBS jobs to run with AFS authentication. It does this by strongly encrypting a user's password so the PBS server can retrieve and decrypt it when the user's job is run. The decrypted password is used to obtain an AFS token, allowing the job to run with AFS authentication. A "shepherd" process is forked into the background to renew the AFS token periodically to ensure that the token never expires while the job is still running.
