I'm trying to develop a formula to predict the Linpack benchmark rating of a Beowulf. To make it easy I assume all nodes have the same processor type and the same bus and memory specifications. The factors I've identified so far are:
To remain sane, I'm disregarding operating system type assuming its running Redhat). I'm also assuming the Beowulf admin software is not a factor (assume Grendel). I'm ignoring disk drive speed also.
I think there are enough data points to do some rough approximation with simple simultaneous equations but I need to determine if I've considered all the factors.
If anyone can identify other factors please let me know. Optimally, I want to produce a formula that will let me generate an approximation of what an X node Beowulf with Y, Z, etc. characteristics will benchmark. I'll scale the formula so there will be diminishing returns over time. Anyway, thanks in advance for any assistance.
