... Security aspects of SMP?
Apart from certain race condition exploits possibly being easier to achieve, I have no idea what that would be. Could you expand a little on what you mean?
Right now its open-ended.
Only if software development continues to be done with the tools of the pre-multi-CPU era. I think software Darwinism will make quick work of those efforts.
... but I seriously don't see any security problems there
Yes, I agree. Multi-CPU systems present the only way to continue the now played-out performance boosts we (software types) were getting for free for a few decades from the chip makers. So now the onus is on the developers of languages and tools that make exploiting multi-CPU systems a manageable job for programmers. But I see very little added security risk in the move to explicitly parallel solutions to performance challenges. I get a strong sense of fear of the unknown from Mr. Aylward.
