getLocal
Description
Get the value of the distributed matrix at global indices gi x gj.
Usage
getLocal(x, gi, gj, all.rank = TRUE, gridinfo)
Arguments
x |
A distributed matrix.
|
gi, gj |
Global row and column indices, respectively.
|
all.rank |
Logical; if TRUE , then all processes will hold the desired
value on exit. Otherwise, only the process who owns the local
value returns this value, while every other process returns NULL .
|
gridinfo |
An optional parameter; each local data lookup requires the data
contained in gridinfo(ICTXT(x)) . So you may specify it
yourself (and if you are making many function calls, this is
preferable performance-wise), or the lookup will be performed
for you.
|
Value
The value at global index gi x gj.
