Hi Santiago,

Well, the problem now is not just "requiring a lot of memory" in a generic sense
but more like requiring a lot of memory *per* CPU.
In fact, I can build the package on machines with 16 GB of RAM having
1 CPU but not on machines with 16 GB having 2 CPUs, where I get this:
c++: fatal error: Killed signal terminated program cc1plus
compilation terminated.
Could you please adjust the number of CPUs to be used according
to available memory?
I did something like that in graph-tool for the same reason:

but I believe now there are more advanced ways to achieve the same.
I was preparing to integrate your solution, but I realized that I
typically build with -j32 on my 64GB workstation. I probably still could
use this solution but it seems like it would be very conservative for
users with more memory available. We should open a new bug to discuss
further, as I'm afraid this is a problem that is going to be very common
in the ROCm stack and we will need a robust solution.
Sincerely,
Cory Bloor
