Implicitly Included Flags

This section contains descriptions of flags that were included implicitly by other flags, but which do not have a permanent home at SPEC.


Commands and Options Used to Submit Benchmark Runs

This result has been formatted using multiple flags files. The "submit command" from each of them appears next.


Submit command from gcc

GNU Compiler Collection Flags

SPECrate runs might use one of these methods to bind processes to specific processors, depending on the config file.


Submit command from Oracle-SPARC

Oracle SPARC Series Platform File

submit=echo 'pbind -b...' > dobmk; sh dobmk (SPEC tools, Unix shell)
When running multiple copies of benchmarks, the SPEC config file feature submit is often used to cause individual jobs to be bound to specific processors. If so, the specific command may be found in the config file; here is a guide to understanding that command:


Commands and Options Used for Feedback-Directed Optimization

No special commands are needed for feedback-directed optimization, other than the compiler profile  flags.


Shell, Environment, and Other Software Settings

This result has been formatted using multiple flags files. The "sw environment" from each of them appears next.


Sw environment from Oracle-Solaris-Studio12.5

Oracle Solaris SPEC CPU Flags

MTEXCLUSIVE
If set to "Y", additional memory allocation buckets will be created, so that threads will not need to share buckets unless more than 2*NCPUS threads are created. This variable is used by mtmalloc.

SUNW_MP_PROCBIND
Binds threads in an OpenMP program to the virtual processors enumerated in the assignment. Can also be set to TRUE, which casues threads to be bound in a round-robin fashion.

SUNW_MP_THR_IDLE
Specifies whether idle threads should SLEEP or SPIN.

STACKSIZE=<n>
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.

ulimit -s <n>
Sets the stack size to n kbytes, or "unlimited" to allow the stack size to grow without limit.
Note that the "heap" and the "stack" share space; if your application allocates large amounts of memory on the heap, then you may find that the stack limit should not be set to "unlimited". A commonly used setting for SPEC CPU2006 purposes is a stack size of 128MB (131072K).


Sw environment from gcc

GNU Compiler Collection Flags

One or more of the following may have been used in the run. If so, it will be listed in the notes sections. Here is a brief guide to understanding them:


Sw environment from Oracle-SPARC

Oracle SPARC Series Platform File

LD_LIBRARY_PATH=<directories>
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.

MADV=access_lwp and LD_PRELOAD=madv.so.1
When the madv.so.1 shared object is present in the LD_PRELOAD list, it is possible to provide advice to the system about how memory is likely to be accessed. The advice present in MADV applies to all processes and their descendants. A commonly used value is access_lwp, which means that when memory is allocated, the next process to touch it will be the primary user. Examples of other possible values include sequential, for memory that is used only once and then no longer needed and acces_many when many processes will be sharing data.

MPSSHEAP=<size>, MPSSSTACK=<size>, and LD_PRELOAD=mpss.so.1
When these variables are set, the mpss.so.1 shared object will set the preferred page size for new processes, and their descendants, to the requested sizes for the heap and stack.


Operating System Tuning Parameters

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.

autoup=<n> (Unix /etc/system)
When the file system flush daemon fsflush runs, it writes to disk all modified file buffers that are more than n seconds old.

bufhwm=<n> (Unix /etc/system)
Sets the upper limit of the file system buffer cache. The units for bufhwm are in kilobytes.

cpu_bringup_set=<n> (Unix /etc/system)
Specifies which processors are enabled at boot time. <n> represents a bitmap of the processors to be brought online.

poweradm set administrative-authority=none (Unix, superuser commands)
Solaris power management settings are determined by an 'administrative-authority'. When the authority is set to 'none', Solaris does not attempt to manage power.

psrset -c <n> (Unix, superuser commands)
Creates a new processor set and displays the new processor set ID.

psrset -e <n> (Unix, superuser commands)
Executes a command (with optional arguments) in the specified processor set. The command process and any child processes are executed only by processors in the processor set.

segmap_percent=<n> (Unix /etc/system)
This value controls the size of the segmap cache as a percent of total memory. Set this value to help keep the file system cache from consuming memory unnecessarily.

STACKSIZE=<n> (Unix environment variable)
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.

svcadm disable webconsole (Unix, superuser commands)
Turns off the Sun Web Console, a browser-based interface that performs systems management. If it is enabled, system administrators can manage systems, devices and services from remote systems.

ts_dispatch_extended=<n> (Unix /etc/system)
Controls which dispatch table is loaded upon boot. A value of 1 loads the large system table, a value of 0 loads the regular system table.

tune_t_fsflushr=<n> (Unix /etc/system)
Controls the number of seconds between runs of the file system flush daemon, fsflush.

user_reserve_hint_pct=<n> (Unix /etc/system)
Informs the system about how much memory is expected to be used by applications (as a percentage).


Virtualization Settings

Virtualization in SPARC systems

SPARC systems provide virtualization capabilities at several levels:

At the time of release of SPEC CPU2017, Oracle submitted results to SPEC for a
1-Chip VM with SPARC M7
which used 2 of the above technologies, namely LDoms and PDoms. The example shown here is that system.

From the point of view of the VM

A SUT (System Under Test) using Oracle VM Server for SPARC is able to accurately inventory cores and virtual processors using ordinary Solaris commands.
In this example system, there are 256 cpus, 32 cores, 1 chip:

$ hostname
m7-16-002c-ld3
$ 
$ pkg info entire | grep Version
          Version: 0.5.11 (Oracle Solaris 11.3.10.5.0)
$ 
$ psrinfo -pv
The physical processor has 32 cores and 256 virtual processors (0-255)
  The core has 8 virtual processors (0-7)
  The core has 8 virtual processors (8-15)
  The core has 8 virtual processors (16-23)

From the point of view of the Host

Oracle VM Server for SPARC manages Logical Domains using the ldm command.
From its point of view, the example SUT just above is ld3, which uses CMIOU11 (Chip/Memory/IO Unit #11).

From the point of view of the Service Processor

Using the Service Processor, a system administrator defines Physical Domains (PDoms).
In the example system, there is one Physical Domain per DCU (Domain Configurable Unit).
CMIOU11 is part of DCU2, which is assigned to HOST2.
