BWA soft memory limit



Is there anyway to impose a soft memory limit to the BWA software? I have need a system to have around 80GB of memory. With 24GB blades this mean I would end up with 96GB of memory, 16GB more than I need and as we all know BWA licensing is not cheap.

Note 1259294 - BWA 7.00: Main memory size for BWA blades, does state that mixed memory sizes are OK. So I could go with 3 x 24GB blades and 1 x 12GB blades to give me 84GB but I am a little uncomfortable with it. Ideally I would like 4 x 24GB blades with a soft limit applied to the BWA software of 84GB. Is this possible?

If not another way to do this would be to limit the amount of memory to 21GB per blade (with the Linux boot parameter mem=x), would this be supported or not?

Thanks in advance.
