pdsh-2.9.rar

Pdsh is a high-performance, parallel remote shell utility. It has built-in, thread-safe clients for Berkeley and Kerberos V4 rsh, and can call SSH externally (though with reduced performance). Pdsh uses a "sliding window" parallel algorithm to conserve socket resources on the initiating node and to allow progress to continue while timeouts occur on some connections. Pdsh is similar to DSH, part of the IBM PSSP software offering, but offers improved performance and handling of error conditions. It runs on a variety of platforms (including as a replacement for DSH on AIX/PSSP), but is primarily developed on Linux. Recently, pdsh has been given the ability to run MPI jobs on the Quadrics Elan3 interconnect under Linux. The binary RPMs provided for download do not provide this functionality; if you wish to use this, consult the source tarball or e-mail the author for more information. Recent versions of pdsh may be downloaded from the LLNL public FTP site at ftp://ftp.llnl.gov/pub/linux/pdsh/
