CACHESIZE


Description
Newton barrier: L2 cache size in kB (kilo bytes) of the CPU. On Intel (or compatible) platforms a value of -1 may be used to determine the cache size automatically.
Type
Integer
Default value
-1
Notes

Specifying the correct L2 cache size can give a significant performance advantage with the Newton barrier algorithm.

If the size is unknown, it is better to specify a smaller size.

If the size cannot be determined automatically on Intel (or compatible) platforms, a default size of 512 kB is assumed.

For multi-processor machines, use the cache size of a single CPU.

Specify the size in kB: for example, 0.5 MB means 512 kB and a value of 512 should be used when setting CACHESIZE.
