D.15.17.4 parallelTestAND
Procedure from library parallel.lib (see parallel_lib).
- Usage:
- parallelTestAND(commands, arguments[, timeout]); commands list or
string, arguments list, timeout int
- Return:
- 1, if commands[i] applied to arguments[i] is not equal to zero for
all i = 1, ..., size(arguments);
0, otherwise.
An optional timeout in ms can be provided. Default is 0 which
disables the timeout. In case of timeout, -1 is returned.
- Note:
- The entries of the list commands must be strings. The entries of the
list arguments must be lists.
commands[i] applied to arguments[i] must evaluate to an integer for
i = 1, ..., size(arguments).
As a shortcut, commands can be a string. This is synonymous to
providing a list of size(arguments) copies of this string.
Example:
| LIB "parallel.lib";
ring R = 0, (x,y,z), dp;
ideal I = x, y, z;
intvec v = 0:3;
list l = list(I, v);
module m1 = x*gen(1);
module m2;
string command = "size";
list arguments1 = list(list(I), list(v), list(l), list(m1));
list arguments2 = list(list(I), list(v), list(l), list(m2));
// test if all the arguments have non-zero size
parallelTestAND(command, arguments1);
==> 1
parallelTestAND(command, arguments2);
==> 0
