SPEC OMP2012 Flag Description - Platform settings
- Simultaneous Multithreading
-
On 2nd generation Intel Xeon Phi processor and co-processors, Simultaneous Multithreading (SMT) permits
4 independent threads of execution on each core.
- Cluster Mode:
-
This bios switch allows 5 options "All2All", "SNC-2", "SNC-4", "Hemisphere"
and "Quadrant". Quadrant mode divide the chip into 4 virtual Quadrants. Quadrant mode can shorten the route length to memory, and that enable us to enlarge the bandwidth of memory.
- Memory Mode:
-
This BIOS switch allows 3 options "Cache", "Flat", and "Hybrid".
Flat mode: the 16GB high bandwidth on-chip MCDRAM
shares a single contiguous address space as the DRAM and is
partitioned onto the second NUMA node.
Cache mode: the MCDRAMs is used as the cache of DDR memory.
Hybrid mode: a portion of the MCDRAM is used in flat mode, the rest is used as cache.
- Turbo Mode:
-
Enabling this switch allows the processor to provide more computing performance at short notice by increasing the frequency above nominal frequency.
