Dear Managers,
My 4-processor ES40 has 4GB of real memory (and some swap). I have a
user who needs to run some vary large programs, but I can't work out
how to let him use more than a gigabyte of the available total for a
single process.
Using the built-in limit in tcsh:
beta % limit datasize unlimited
beta % limit stacksize unlimited
beta % limit memoryuse unlimited
beta % limit vmemoryuse unlimited
But then:
beta % limit
cputime unlimited
filesize unlimited
datasize 1048576 kbytes
stacksize 32768 kbytes
coredumpsize unlimited
memoryuse 4097016 kbytes
vmemoryuse 4194304 kbytes
descriptors 4096
or even:
beta % ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 1048576
stack(kbytes) 32768
memory(kbytes) 4097016
coredump(blocks) unlimited
nofiles(descriptors) 4096
vmemory(kbytes) 4194304
Presumably these are maximum limits set somewhere system-wide. Where
are they set, and how could I change them?
Many thanks,
Andrew
