comment Complement[] changes order of elements?
@Mr.Wizard, it was late and I was too lazy to properly check if both questions were asking the same thing, so I just posted the link in case anyone else was looking for it. As there are still no close votes I guess the community consensus is that it's not a duplicate.

For symbolic computations I would have thought that clock speed was a stronger consideration than number of cores?

comment Summing Normal random variables
This is incorrect. The OP wanted the PDF of the sum of two random variables, not the sum of two PDFs.

I have done a major edit to your question to clarify and simplify it. I believe it is now answerable so will vote for it to be reopened.

As for actually answering the question, it would help a lot if you stated what output you are expecting. Do you just need the sum of all the solutions for X? Or perhaps a list of {1st solution, 1st + 2nd solution, 1st + 2nd + 3rd, etc...}

It would have been better to edit the original question to address why that answer was no good for you. Editing bumps the question - giving it more visibility - and it isn't considered rude, whereas deleting and reposting when people have already invested effort in trying to help you is rude.

comment Why do I get Floor and Ceiling in my output despite my assumptions
@bills This is strange. Surely using the Assumptions option to Sum, setting the global $Assumptions and using Assuming should all have the same effect?

comment How to speed up band matrix-matrix multiplication?
What version are you using? With version 10 on Windows I get 1.75 secs for a.u and 1.2 secs for a2.u (but with an added overhead of 2.4 secs to calculate part)
