Hello, we are using a PC's clusters at the Instituto de Fisica at UNAM, we
are trying to run an application that needs the number in
/proc/sys/kernel/shmmax to be increased, I can change the number with

echo "134217728" > /proc/sys/kernel/shmmax

but only in the master node, we are using Scyld, and when I try:

bpsh -a echo "134217728" > /proc/sys/kernel/shmmax

and then I do:

bpsh -a cat  /proc/sys/kernel/shmmax

it answers:

33554432
33554432
33554432
33554432

33554432
33554432
