Re: getting total memory size on OSX?

using sysctlbyname to get hw.physmem will not work on systems with more than 2GB of ram (it returns a signed int)

use hw.memsize instead:


uint64_t mem;
size_t len = sizeof(mem);

sysctlbyname("hw.memsize", &mem, &len, NULL, 0);

Currently, Gridengine uses host_info() to get the
memory_size.

However, sizeof(host_basic_info.memory_size) is 4, so
for machines with 4GB of memory or more, is there a
better call the get the memory size?

I've tried sysctlbyname():
