PAR Technologies PARASTATION5 V5 - Manual (Page 45)

ParaStation5 Administrator's Guide 41
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.
