The Prospero Resource Manager Version 1.1.1

The latest version of PRM is 1.1.1.

Version 1.1.1 of the Prospero Resource Manager (PRM) is available as a compressed tarfile prm-1.1.1.tar.Z includes sources for Version 1.1.1, documentation and some demo programs that illustrate the operation of PRM.

Version 1.1.1 is a bug fix to Version 1.1. If you are already using 1.1, download this patchfile to PRM's top level directory on your machine and apply the patch as

patch -p1 < patch1.1.01

If you are building PRM on a Sparc machine and wish to install it with task migration capabilities, you must retrieve and unpack the checkpointing-extensions, ckpt_extn.tar.Z. This contains portions of Condor version 4.1.3b that PRM uses, and is available only for Sparc workstations. It must be unpacked in the same directory that the PRM distribution was unpacked in. When unpacked, it creates and populates the directory PRM/src/sun4/condor. To obtain the checkpointing extensions, click here.
