decreasing #define HZ in the linux kernel for CPU/memory bound apps ?

[Cabaniols, Sebastien]

Hi beowulfs!

Would it be interesting to decrease the #define HZ in the linux kernel
for CPU/Memory bound computationnal farms  ?
(I just posted the same question to lkml)

I mean we very often have only one running process eating 99% of 
the CPU, but we (in fact I) don't know if we loose time doing context
switches ....

Did anyone experiment on that ?

Thanks in advance
