| .SH DESCRIPTION |
| .ft R |
| This subroutine is used to add a new back end at runtime, once added, |
| the id of the new back end id will be added to the predefined group |
| \fBSCI_GROUP_ALL\fP. |
| .sp |
| In \fIsci_be_t\fP: |
| .sp |
| .nf |
| typedef struct { |
| int id; |
| char *hostname; |
| } sci_be_t; |
| .fi |
| .sp |
| \fIid\fP indicates the id of the new back end, it can be -1 (means its id will be |
| assigned by SCI) or a postive value, \fIhostname\fP specified the host to launch |
| this new back end. |
| .sp |
| Together with \fBSCI_BE_remove\fP, these two functions can be used to add/remove |
| back ends dynamically at runtime. |
