This macro indicates that the benchmark is being compiled on an AMD64-compatible system running the Linux operating system.
This macro determines which file system interface will be used. Common file i/o calls like stat() and readdir() return off_t data that may or may not fit within a 32bit data structure if this flag is not used. With _FILE_OFFSET_BITS=64, types like off_t have a size of 64 bits. The truncation that happens without _FILE_OFFSET_BITS=64 has been observed to yield intermittent failures.
Ex: RHEL7 distributions format partitions using xfs. Runtime errors are observed on such systems because sometimes returned values will not fit into 32bit data types that are a mismatch for xfs.

Controls the level of memory layout transformations performed by the compiler. This option can improve cache reuse and cache locality.
Option standard-realloc-lhs (the default), tells the compiler that when the left-hand side of an assignment is an allocatable object, it should be reallocated to the shape of the right-hand side of the assignment before the assignment occurs. This is the current Fortran Standard definition. This feature may cause extra overhead at run time. This option has the same effect as option assume realloc_lhs.
If you specify nostandard-realloc-lhs, the compiler uses the old Fortran 2003 rules when interpreting assignment statements. The left-hand side is assumed to be allocated with the correct shape to hold the right-hand side. If it is not, incorrect behavior will occur. This option has the same effect as option assume norealloc_lhs.
The align toggle changes how data elements are aligned. Variables and arrays are analyzed and memory layout can be altered. Specifying array32byte will look for opportunities to transform and reailgn arrays to 32byte boundaries.

This section contains descriptions of flags that were included implicitly by other flags, but which do not have a permanent home at SPEC.
Enable optimizations for speed. This is the generally recommended
optimization level. This option also enables:
- Inlining of intrinsics
- Intra-file interprocedural optimizations, which include:
- inlining
- constant propagation
- forward substitution
- routine attribute propagation
- variable address-taken analysis
- dead static function elimination
- removal of unreferenced variables
- The following capabilities for performance gain:
- constant propagation
- copy propagation
- dead-code elimination
- global register allocation
- global instruction scheduling and control speculation
- loop unrolling
- optimized code selection
- partial redundancy elimination
- strength reduction/induction variable simplification
- variable renaming
- exception handling optimizations
- tail recursions
- peephole optimizations
- structure assignment lowering and optimizations
- dead store elimination
Enable optimizations for speed and disables some optimizations that increase code size and affect speed.
To limit code size, this option:
The O1 option may improve performance for applications with very large code size, many branches, and execution time not dominated by code within loops.
-O1 sets the following options:Tells the compiler the maximum number of times to unroll loops. For example -funroll-loops0 would disable unrolling of loops.
-fno-builtin disables inline expansion for all intrinsic functions.
This option trades off floating-point precision for speed by removing the restriction to conform to the IEEE standard.
EBP is used as a general-purpose register in optimizations.
Places each function in its own COMDAT section.
Flushes denormal results to zero.
Enable O2 optimizations plus more aggressive optimizations, such as prefetching, scalar replacement, and loop and memory access transformations. Enable optimizations for maximum speed, such as:
On IA-32 and Intel EM64T processors, when O3 is used with options -ax or -x (Linux) or with options /Qax or /Qx (Windows), the compiler performs more aggressive data dependency analysis than for O2, which may result in longer compilation times. The O3 optimizations may not cause higher performance unless loop and memory access transformations take place. The optimizations may slow down code in some cases compared to O2 optimizations. The O3 option is recommended for applications that have loops that heavily use floating-point calculations and process large data sets.
OS Tuning
setterm:
Used to disable screen blanking on text console:
ulimit:
Used to set user limits of system-wide resources. Provides control over resources available to the shell and processes started by it. Some common ulimit commands may include:
Disabling Linux services:
Certain Linux services may be disabled to minimize tasks that may consume CPU cycles.
irqbalance:
Disabled through "service irqbalance stop". Depending on the workload involved, the irqbalance service reassigns various IRQ's to system CPUs. Though this service might help in some situations, disabling it can also help environments which need to minimize or eliminate latency to more quickly respond to events.
Performance Governors (Linux):
In-kernel CPU frequency governors are pre-configured power schemes for the CPU. The CPUfreq governors use P-states to change frequencies and lower power consumption. The dynamic governors can switch between CPU frequencies, based on CPU utilization to allow for power savings while not sacrificing performance.
Other options beside a generic performance governor can be set, such as the perf-bias:
--perf-bias, -b
On supported Intel processors, this option sets a register which allows the cpupower utility (or other software/firmware) to set a policy that controls the relative importance of performance versus energy savings to the processor. The range of valid numbers is 0-15, where 0 is maximum performance and 15 is maximum energy efficiency.
The processor uses this information in model-specific ways when it must select trade-offs between performance and energy efficiency. This policy hint does not supersede Processor Performance states (P-states) or CPU Idle power states (C-states), but allows software to have influence where it would otherwise be unable to express a preference.
On many Linux systems one can set the perf-bias for all CPUs through the cpupower utility with one of the following commands:
Tuning Kernel parameters:
The following Linux Kernel parameters were tuned to better optimize performance of some areas of the system:
Transparent Huge Pages (THP):
THP is an abstraction layer that automates most aspects of creating, managing, and using huge pages. THP is designed to hide much of the complexity in using huge pages from system administrators and developers, as normal huge pages must be assigned at boot time, can be difficult to manage manually, and often require significant changes to code in order to be used effectively. Transparent Hugepages increase the memory page size from 4 kilobytes to 2 megabytes. Transparent Hugepages provide significant performance advantages on systems with highly contended resources and large memory workloads. If memory utilization is too high or memory is badly fragmented which prevents hugepages being allocated, the kernel will assign smaller 4k pages instead. Most recent Linux OS releases have THP enabled by default.
Linux Huge Page settings:
If you need finer control and manually set the Huge Pages you can follow the below steps:
Note that further information about huge pages may be found in your Linux documentation file: /usr/src/linux/Documentation/vm/hugetlbpage.txt
Firmware Settings
Power Policy Quick Settings: (Default = Standard)
This BIOS option controls the performance or power save setting, user can use this item to change it. Best performance can maximize the performance of the server. Energy efficiency can maximize the power efficiency of the server.
Values for this BIOS setting can be:
SR-IOV Support (Default = Enabled):
If system has SR-IOV capable PCIe Devices, this option Enables or Disables Single Root IO Virtualization Support. Values for this BIOS option can be:
Stale AtoS (Default = Auto):
Stale AtoS (sometimes called A2S) is the transition of a directory line state. The in-memory directory has three states: I, A, and S. Invalid (I) state means the data is clean and does not exist in any other socket’s cache. snoopAll (A) state means the data may exist in another socket in exclusive or modified state. Shared (S) state means the data is clean and may be shared across one or more socket’s caches. When doing a read to memory, if the directory line is in the A state we must snoop all the other sockets because another socket may have the line in modified state. If this is the case, the snoop will return the modified data. However, it may be the case that a line is read in A state and all the snoops come back a miss. This can happen if another socket read the line earlier and then silently dropped it from its cache without modifying it. Values for this BIOS option can be:
LLC dead line alloc (Default = Enable):
In the Intel® Xeon® Scalable family non-inclusive cache scheme, MLC evictions are filled into the LLC. When lines are evicted from the MLC, the core can flag them as “dead” (in other words, not likely to be read again). The LLC has the option to drop dead lines and not fill them in the LLC. This can help save space in the LLC and prevent the LLC from evicting useful data. Values for this BIOS option can be:
Hardware P-States (Default = Native Mode):
Processors provide a flexible interface between hardware and the platform, enhancing performance management and improving energy efficiency. Hardware P-states (HWP) refers to the set of algorithms used to dynamically determine core frequency. When HWP is 'Disable' or 'OOB', Dynamic SST-PP will be disabled. SST-BF can only be enabled when HWP mode is 'Native Mode with No Legacy Support'. Values for this BIOS option can be:
Hyper-Performance (Default = Disabled):
Hyper-Performance support depends on the CPU. Enabling Hyper-Performance may require a better cooling solution (such as a heatsink or D2C liquid cooling) to prevent the CPU from overheating and throttling. This BIOS option providing a knob for tuning processor Voltage Regulator chipset(power supply), allowing the user to adjust the performance level. Values for this BIOS option can be:
Enforce DDR Memory Frequency POR (Default = Enforce POR):
Enforces Plan Of Record restrictions for DDR frequency voltage programming, [Disable] option is over spec and depend on memory quality. Values for this BIOS option can be:
