Bug#1074032: (no subject)

[Mark Glines]

Steve is right.


When I run `ulimit -Hn 1048576`, the memory allocation according to 
`strace` is greatly reduced, and the nvidia-smi command completes 
immediately.

2301004 prlimit64(0, RLIMIT_NOFILE, NULL, {rlim_cur=1024, 
rlim_max=1024*1024}) = 0 2301004 mmap(NULL, 4198400, 
PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f4702800000 
2301004 mmap(NULL, 50335744, PROT_READ|PROT_WRITE, 
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f46ff600000

4GB and 51GB became 4MB and 50MB. So the memory usage (and 
initialization overhead?) scales with the max file descriptor limit.

Thanks,

Mark
