| NAME |
| SCI_BE_add - Add a new back end at runtime |
| |
| C Syntax |
| #include <sci.h> |
| int SCI_BE_add(sci_be_t *be) |
| |
| INPUT PARAMETERS |
| be |
| The information of the back end to be added (INOUT). |
| |
| DESCRIPTION |
| 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 |
| SCI_GROUP_ALL. |
| |
| In sci_be_t: |
| |
| typedef struct { |
| int id; |
| char *hostname; |
| } sci_be_t; |
| |
| id indicates the id of the new back end, it can be -1 (means its id |
| will be assigned by SCI) or a postive value, hostname specified the |
| host to launch this new back end. |
| |
| Together with SCI_BE_remove, these two functions can be used to |
| add/remove back ends dynamically at runtime. |
| |
| For more information, please refer to SCI's online documents. |
