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]

Env[ironment] { {

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.
