GEXEC 0.3.6

GEXEC is a scalable cluster remote execution system which provides fast, RSA authenticated remote execution of parallel and distributed jobs.
It provides transparent forwarding of stdin, stdout, stderr, and signals to and from remote processes, provides local environment propagation, and is designed to be robust and to scale to systems over 1000 nodes. Internally, GEXEC operates by building an n-ary tree of TCP sockets and threads between gexec daemons and propagating control information up and down the tree. By using hierarchical control, GEXEC distributes both the work and resource usage associated with massive amounts of parallelism across multiple nodes, thereby eliminating problems associated with single node resource limits (e.g., limits on the number of file descriptors on front-end nodes). The initial release of the software is made of a daemon, a client program, and a library that provides programmatic interface to the GEXEC system.
Enhancements:
- Modified xinetd file to set LD_ASSUME_KERNEL="2.2.5" to deal with LinuxThreads not implementing all POSIX cancellation points
- Modified gexec.spec.in to use a build root so RedHat 9s broken version of rpmbuild builds without the infamous "getOutputFrom(): Broken pipe" error.
