Pattern	Name	Description

0x0002	RDP_LOG_INIT	Info from initialization (IP, FE, NFTS etc.)

0x0004	RDP_LOG_INTR	Interrupted syscalls

0x0008	RDP_LOG_DROP	Message dropping and resequencing

0x0010	RDP_LOG_CNTR	Control messages and state changes

0x0020	RDP_LOG_EXTD	Extended reliable error messages (on linux)

0x0040	RDP_LOG_COMM	Sending and receiving of data (huge! amount)

0x0080	RDP_LOG_ACKS	Resending and acknowledging (huge! amount)

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:

Pattern	Name	Description

0x0001	MCAST_LOG_INIT	Info from initialization (IP etc.)

0x0002	MCAST_LOG_INTR	Interrupted syscalls

0x0004	MCAST_LOG_CONN	T_CLOSE and new pings

0x0008	MCAST_LOG_5MIS	Every 5th missing ping

0x0010	MCAST_LOG_MSNG	Every missing ping

0x0020	MCAST_LOG_MSNG	Every received ping

0x0040	MCAST_LOG_SENT	Every sent ping

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.
