sharedmatrix
SHAREDMATRIX Allows any Matlab object (e.g., struct, nd-cell, nd-matrix, sparse matrix) to be shared between multiple Matlab sessions without resorting to file I/O. The Matlab sessions must have access to the same shared memory resources, i.e., the processes are on the same physical system. This program uses shared memory functions specified by POSIX and in doing so avoids disk I/O for sharing. The program should work on any Linux variant but was only tested on Ubuntu.
*UPDATE: Thanks to contributor Andrew Smith, we now support Windows through the Boost InterProcess library. The windows version has not been tested by the first author.
% For example, assuming you have data X:
shmkey=12345;
sharedmatrix('clone',shmkey,X);
clear X;
spmd(8)
X=sharedmatrix('attach',shmkey);
% do something with X
sharedmatrix('detach',shmkey,X);
end
sharedmatrix('free',shmkey);
