Description:
Set or get the number of memory zone holding a specified task on the current node.

hosts(i;j)

The function gets the number of memory zone accommodating task j on the current node when parameter i is absent; sets the number of memory zone holding task j on the current node when both parameter i and parameter j are present; and clear the existing memory zone number when i is 0. It is usually used in the initiation file init.splx.
Parameter:

i |

=hosts(2;"task2") |
Set the number of memory zone holding task 2 on the current node as 2, and return true. |
|
2 |
=hosts(;"task2") |
Get the number of memory zone holding task 2 on the current node as 2, and return true. |
|
3 |
=hosts(0;"task2") |
Delete the number of memory zone holding task 2 and return true since parameter i is 0. |
