Table 3. RDP debug flags

mcastdebug

mask

[

nodes

]

Set the debugging mask of the MCast protocol within the ParaStation daemon psid(8) to

mask

on

the selected node(s).

Unless you want to debug the MCast protocol (i.e. the protocol used by the
daemons to ping alive-messages to each other) this parameter is not really
useful.

Mask

is the bit-wise disjunction of the following bit patterns:

Table 4. Multicast debug flags

freeOnSuspend [ 0 | 1 ] [

nodes

]

Switch the

freeOnSuspend

flag on or off on the selected nodes.

The

freeOnSuspend

flag steers the behavior of the resource management concerning suspended

jobs. Basically there are two possible approaches: Either the resources used by the suspended
job are freed for other jobs (this is done, if the flag is set to 1) or they are kept occupied in order
to preserve them exclusively for the time the job continues to run (this is the behavior as long as
the flag has the value 0).

Since the master node does all the resource management within the cluster, only the value on this
node actually steers the behavior.

This flag can be set persistently via the freeOnSuspend option within the ParaStation configuration
file parastation.conf(5).

handleOldBins [ 0 | 1 ] [

nodes

]

Switch the compatibility flag for applications linked against version 4.0.x of ParaStation on or off
on the selected nodes.
