The default port to use is 886.

RLimit { Core size CPUTime time DataSize size MemLock size StackSize size RSSize size }

RLimit { { Core size CPUTime time DataSize size MemLock size StackSize size RSSize size }... }

Set various resource limits to the psid(8) and thus to all processes started from it.

All limits are set using the setrlimit(2) system call. For a detailed description of the different types of limits please refer to the corresponding manual page.

If no RLimits are set within the ParaStation configuration files, no changes are made to the systems default value.

The following (soft) resource limits may be set:

Core size

Set the maximum size of a core-file to size kilobytes. size is an integer number, the string “infinity” or the string “unlimited”. In the two latter cases the data size is set to RLIM_INFINITY.

Starting with version 5.0.3, this configuration will also control the writing of core-files for the psid itself, in case a catastrophic failure occurs.

CPUTime time

Set the maximum CPU time that might be consumed by the daemon to time seconds. time has to be an integer number, the string “infinity” or the string “unlimited”. In the two latter cases the data size is set to RLIM_INFINITY.

DataSize size

Set the maximum data size to size kilobytes. size is an integer number, the string “infinity” or the string “unlimited”. In the two latter cases the data size is set to RLIM_INFINITY.

MemLock size

Set the maximum amount of memory that might be locked into RAM to size kilobytes. size is an integer number, the string “infinity” or the string “unlimited”. In the two latter cases the data size is set to RLIM_INFINITY.

StackSize size

Set the maximum stack size to size kilobytes. size is an integer number, the string “infinity” or the string “unlimited”. In the two latter cases the stack is set to RLIM_INFINITY.

RSSize size

Set the maximum Resident Set Size (RSS) to size pages. size is an integer number, the string “infinity” or the string “unlimited”. In the two latter cases the RSS is set to RLIM_INFINITY.

Env[ironment] name value

Env[ironment] { {name value }... }

Set environment variables for the ParaStation daemon psid(8) and any application started via this daemon.

This command again has two different modes. While within the first form exactly one variable is set, within the environment form of this command as many variables as wanted may be set. The general form of the latter case is one variable per line.
