[openMosix-general] Node tuning

[Kevin N. C. <ke...@se...>]

Hi all.

I'm currently playing around with a 5 node system.  Node 1 exist at the 
opposite end of a 14mbs network connection.  Nodes 2-5 are connected via 
a 100mbs hub (half duplex).

If I crank up (5) CPU intensive processes on Node 1, they migrate nicely 
to the other 4 nodes.  However, apparently due to the slow interconnect, 
the processes swap around a lot and vary in CPU usage from 40-96%.

If I shutdown node 1, and crank up (4) processes on the remaining nodes, 
they run at 99.9%.

FWIW - I'm using the ECCP2 DC executable.  This process has a 496KB 
working set size per TOP, when running locally.  When run under 
Openmosix, TOP shows 204KB for the remote tasks (shown as sleeping) and 
316KB for the local task (shown as running).

What can I do to use all 5 nodes efficiently?  All (5) are the same with 
regards to CPU & motherboard.  Node 1 has a bit more memory and a hard 
disk.  Nodes 2->5 have less memory and are diskless.

Thanks,

Kevin C.
