Broadcast large matrix to slaves

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I'd like to broadcast a large matrix symmetrical matrix (17190 x 17190) to all
slaves. However I get the following error:
Error: serialization is too large to store in a raw vector

Is there any way I could send such a large matrix to the slaves? Since it's
symmetrical I could send just one triangle along with the diagonal, but I'd like
to know why a large matrix can't be sent and if it can be circumvented!

Cheers,
Nath
