NAME

gfreg - register a Gfarm file, Gfarm file fragments, or a Gfarm directory

SYNOPSIS

gfreg [ -p ] [ -h filesystem-node | -H hostfile | -D domainname ] [ -a architecture ] program ... gfarm-URL

gfreg [ -i ] [ -h filesystem-node | -H hostfile | -D domainname ] localfile ... gfarm-URL

gfreg -N total-num-of-fragments -I fragment-index [ -h filesystem-node | -H hostfile | -D domainname ] localfile ... gfarm-URL

gfreg -r [ -h filesystem-node | -H hostfile | -D domainname ] [ -a architecture ] [ directory | program | localfile ] ... gfarm-URL

DESCRIPTION

The first form copies and registers the program as a Gfarm file gfarm-URL in the Gfarm filesystem. When gfarm-URL is a directory, multiple programs can be specified. After the registration, the gfarm-URL can be specified as a program name of gfrun(1) and gfmpirun_p4(1). Without the -p option, only executable file can be specified. With the -p option, non-executable file can be specified as well. Without the -a option or the -h option, architecture of the program is assumed to be the same architecture as the client host on that gfreg(1) is executed, which is obtained by the Gfarm metaserver.

The second form registers one or more localfiles as a single Gfarm file. Without the -i option, only non-executable file can be specified as localfile. With the -i option, both excutable and non-executable file can be specified as localfile. The destination filesystem node will be automatically selected by CPU load average. With any one of -h, -H, -D options, filesystem node can be limited.

The third form registers localfile as a file fragment of a Gfarm file. The total number of fragments and the fragment index are specified by the -N option and the -I option, respectively. When gfarm-URL is a directory, multiple localfiles can be specified. The destination filesystemnode will be automatically decided by CPU load average unless any one of -h, -H, -D options is explicitly specified. When the gfreg command of this form is executed on a filesystem node, the local filesystem node is always selected rather than a remote filesystemnode. In this case, -h, -H, -D options help to store files dispersively.

The fourth form registers the directory as a Gfarm directory gfarm-URL, the program or the localfile as a Gfarm file gfarm-URL. If directory have some sub directories and/or files, they will be registered recursively. The non-executable file localfile will be registered as a file has one fragment. A non-executable file in the directory will be registered in the same way. When gfarm-URL already exists as a directory, multiple directories, programs, and localfiles can be specified and they will be registered in gfarm-URL. They can be mixed in parameteres, while other forms inhibit this manner. If gfarm-URL does not exist, one directory or one program, or one localfile can be specified and it will be registered as gfarm-URL. Refer to the first form's part above to specify filesystem node thatprogfarms and files will reside with the -a option or the -h option.

OPTIONS

-f
overwrites gfarm-URL even if it exits as a Gfarm file.
-?
displays a list of command options.
