ParallelMap
ParallelMap
[
f
,
expr
]
applies
f
in parallel to each element on the first level in
expr
.
ParallelMap
[
f
,
expr
,
levelspec
]
applies
f
in parallel to parts of
expr
specified by
levelspec
.
MORE INFORMATION
ParallelMap
is a parallel version of
Map
, which automatically distributes different applications of
f
among different kernels and processors.
ParallelMap
will give the same results as
Map
, except for side effects during the computation.
ParallelMap
uses the same level specifications as
Map
. Not all level specifications can be parallelized.
Parallelize
[
Map
[
f
,
expr
]]
is equivalent to
ParallelMap
[
f
,
expr
]
.
If an instance of
ParallelMap
cannot be parallelized it is evaluated using
Map
.
ParallelMap
takes the same
Method
option as
Parallelize
.
