The Cell Messaging Layer 1.0 (Default branch)
The Cell Messaging Layer is a communication library for clusters of Cell Broadband Engine processors. It implements a subset of the popular MPI message-passing API on the Cell's SPE processors, with one MPI rank per SPE across any number of Cells and the ability for any SPE to communicate directly with any other SPE, even across a network. The Cell Messaging Layer thereby makes programming clusters of Cell processors similar to programming clusters of conventional CPUs. License: GNU General Public License v2 Changes:
This release fixes two critical bugs that would sometimes cause code running across multiple Cell blades to hang. The Cell Messaging Layer now seems to run reliably on clusters of Cell processors.Image

fs_getcellstatus

FS_GETCELLSTATUS(1)					       AFS Command Reference					       FS_GETCELLSTATUS(1)

NAME

       fs_getcellstatus - Reports whether setuid programs are honored in a cell

SYNOPSIS

       fs getcellstatus -cell <cell name>+ [-help]

       fs getce -c <cell name>+ [-h]

DESCRIPTION

       The fs getcellstatus command reports whether the Cache Manager allows programs fetched from each specified cell to run with setuid
       permission. To set a cell's setuid status, use the fs setcell command; fs_setcell(1) fully describes how AFS treats setuid programs.

OPTIONS

       -cell <cell name>+
	   Names each cell for which to report setuid status. Provide the fully qualified domain name, or a shortened form that disambiguates it
	   from the other cells listed in the local /etc/openafs/CellServDB file.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output reports one of the following two values as appropriate:

	  Cell <cell> status: setuid allowed
	  Cell <cell> status: no setuid allowed

EXAMPLES

       The following example indicates that programs from the cell "abc.com" are not allowed to run with setuid permission.

	  % fs getcellstatus abc.com
	  Cell abc.com status: no setuid allowed

PRIVILEGE REQUIRED

       None
