![[benchmark]](http://www.spec.org/auto/accel/flags/benchmark.png)
Used to leave a buffer space for the main kernel. Set this to a small integer value (like 1) if needed.
Platform settings
One or more of the following settings may have been applied to the testbed. If so, the "Platform Notes" section of the report will say so; and you can read below to find out more about what these settings mean.
LD_LIBRARY_PATH=<directories> (linker)
LD_LIBRARY_PATH controls the search order for both the compile-time and run-time linkers. Usually, it can be
defaulted; but testers may sometimes choose to explicitly set it (as documented in the notes in the submission), in order to
ensure that the correct versions of libraries are picked up.
STACKSIZE=<n> (Unix)
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.
ulimit -s <n> (Unix)
Sets the stack size to n kbytes, or "unlimited" to allow the stack size to grow without limit.
