Intel(R) Optimized LINPACK Benchmark extended help information
|
||||
|
||||
About Intel(R) Optimized LINPACK Benchmark:
|
||||
|
||||
Intel(R) Optimized LINPACK Benchmark is a generalization of the LINPACK 1000
|
||||
benchmark which solves a dense (real*8) system of linear equations (Ax=b),
|
||||
measures the amount of time it takes to factor and solve the system, converts
|
||||
that time into a performance rate and tests the results for accuracy. The
|
||||
generalization is in the number of equations (N) we can solve, which is not
|
||||
limited to 1000. We use partial pivoting to assure the accuracy of the
|
||||
results. This benchmark should not be used to report LINPACK 1000 performance
|
||||
as that is a compiled-code only benchmark. This is a shared memory
|
||||
implementation which runs on a single platform and should not be confused with
|
||||
MP LINPACK, which is a distributed memory version of the same benchmark. This
|
||||
benchmark should not be confused with LINPACK, the library, which has been
|
||||
expanded upon by LAPACK the library.
|
||||
|
||||
Binaries and the running environment.
|
||||
|
||||
Intel Optimized LINPACK Benchmark uses these names for the executables to be
|
||||
run:
|
||||
linpack_xeon32.exe Windows*, Intel(R) Xeon(R) 32-bit
|
||||
linpack_xeon64.exe Windows*, Intel(R) Xeon(R) 64-bit, supports
|
||||
Automatic Offload mode
|
||||
xlinpack_xeon32 Linux*, Intel(R) Xeon(R) 32-bit
|
||||
xlinpack_xeon64 Linux*, Intel(R) Xeon(R) 64-bit, supports
|
||||
Automatic Offload mode
|
||||
xlinpack_mic Linux*, Intel(R) MIC(R) 64-bit
|
||||
linpack_cd32 OS X*, Intel(R) Core(TM) microarchitecture 32-bit
|
||||
linpack_cd64 OS X*, Intel(R) Core(TM) microarchitecture 64-bit
|
||||
The name 'linpack' stands for any of these binaries below in the text of this
|
||||
extended help information. 'LINPACK' shall stand for this Intel Optimized
|
||||
LINPACK Benchmark application. Which of these binaries will be present in
|
||||
the package depends on which package was installed.
|
||||
|
||||
LINPACK makes use of SMP parallelism and by default generates as many
|
||||
threads of execution as the number of the processors of the SMP system. One can
|
||||
override the default number of threads by setting the environment variable
|
||||
OMP_NUM_THREADS to any positive number. Note that performance is usually
|
||||
maximized when the number of the threads is equal to the number of cores (so,
|
||||
for a two socket dual-core system, 4 would be ideal).
|
||||
|
||||
Usage:
|
||||
|
||||
linpack
|
||||
linpack -h[elp]
|
||||
linpack -e[xtended_help]
|
||||
linpack [-i[nput_file]] data_file
|
||||
linpack < data_file
|
||||
|
||||
Here is an explanation for the options.
|
||||
|
||||
linpack
|
||||
when used without options, LINPACK prints this prompt
|
||||
Input data or print help ? Type [data]/help :
|
||||
and waits for the input. If 'help' was typed, it prints brief usage
|
||||
information (just like a 'linpack -h[elp]' form) and quits. Otherwise,
|
||||
be ready to input data for a LINPACK run. Enter the 4 numbers on the
|
||||
following prompts:
|
||||
Number of equations to solve (problem size):
|
||||
Leading dimension of array:
|
||||
Number of trials to run:
|
||||
Data alignment value (in Kbytes):
|
||||
See notes on the input data below.
|
||||
The output will contain the system information, input data and test results.
|
||||
See notes on the output data format below.
|
||||
The "linpack_cd32" will hang without a data file.
|
||||
|
||||
linpack -h[elp]
|
||||
prints brief usage information and quits
|
||||
|
||||
linpack -e[xtended_help]
|
||||
prints this extended help information and quits
|
||||
|
||||
linpack [-i[nput_file]] data_file
|
||||
linpack < data_file
|
||||
makes LINPACK run with the input data contained in 'data_file'. LINPACK
|
||||
allows a user to either enter data manually or with a data file. Manual
|
||||
data can be provided when LINPACK is executed with no arguments. Below we
|
||||
provide a sample of the data file format and give a brief description of
|
||||
its contents.
|
||||
Data file sample (next 7 lines):
|
||||
Intel(R) Optimized LINPACK Benchmark datafile
|
||||
User-defined string
|
||||
5 # number of tests
|
||||
1000 2000 3000 4000 5000 # number of equations (problem sizes)
|
||||

|
||||
4 4 2 1 1 # number of times to run a test (trials)
|
||||
4 4 4 4 4 # alignment values (in KBytes)
|
||||
Data file format description:
|
||||
Line 1 is discarded.
|
||||
Line 2 is printed on the standard output as it is.
|
||||
Line 3 begins with the number of tests, must be non-negative.
|
||||
Lines 4, 5, 6, 7 contain the values of the four specified parameters
|
||||
(a number of equations, a leading dimension, times to run a test, alignment
|
||||
value in KBytes) for each of the tests. The number of the values on each
|
||||
line from 4 to 7 must be no less than the number of tests.
|
||||
Note that in the current LINPACK version the number of tests is
|
||||
restricted by 32, so only the first 32 tests will be performed if the
|
||||
greater number of the tests is specified.
|
||||
See the notes on the input data values and the output data format below.
|
||||
|
||||
Notes on the Intel Optimized LINPACK Benchmark input data values
|
||||
|
||||
Every LINPACK test is defined by the 4 input parameters values:
|
||||
Number of equations to solve (problem size)
|
||||
Leading dimension of array
|
||||
Number of trials to run
|
||||
Data alignment value (in Kbytes)
|
||||
One can set no more than 1 test per an executable run in case of manual
|
||||
input (with 'linpack' usage), or up to 32 tests in case of the package form
|
||||
input (with 'linpack ... data_file' usage). The rules for every test's set
|
||||
are as follows.
|
||||
The number of equations must be positive, this value (with the couple of the
|
||||
leading dimension value) is restricted only by the memory available. LINPACK
|
||||
solves a real*8 system of linear equations; just to store the matrix
|
||||
requires at least 8*(leading dimension)*(number of equations) bytes. Each
|
||||
test or trial may have a different memory requirement, but the program may
|
||||
exit if given a leading dimension and number of equations too large.
|
||||
The leading dimension must be no less than the number of equations.
|
||||
Experience has shown that the best performance for a given problem size
|
||||
is obtained when the leading dimension is set to the nearest odd
|
||||
multiple of 8 (16 for Intel(R) AVX processors) equal to or larger
|
||||
than the number of equations (divisible by 8 but not by 16, or
|
||||
divisible by 16 but not 32 for Intel(R) AVX processors).
|
||||
Two other input values must be non-negative.
|
||||
The number of trials determines how many runs with the same initial data
|
||||
will be accomplished repeatedly.
|
||||
The alignment value allows the arrays to be aligned to the value specified,
|
||||
zero means that no specific alignment will be performed - the arrays are
|
||||
used as they are allocated.
|
||||
The best performance is likely to be obtained when arrays are aligned to
|
||||
the page size boundary.

Notes on Creating the Input Data files
|
||||
|
||||
The product is released with sample data files. These are set up to
|
||||
provide good performance numbers with an ideal memory configuration.
|
||||
Users may find that their memory configuration is smaller than the
|
||||
predefined inputs. In this event, take a sample data file as described
|
||||
above. Note that the most significant part is determining the largest
|
||||
problem size. While the above text talks to problem sizes and how they
|
||||
match memory, here we will walk through an example.
|
||||
Suppose the target machine only has 4 GBytes of memory (and assuming that
|
||||
OS allows one to do a malloc of size 4 GB as well.) Note that
|
||||
22000*22000*8 is 3.872 billion bytes, which is close to the maximum
|
||||
malloc size. We can try a problem size of 22000 interactively first.
|
||||
If this is an Intel(R) Itanium(R) 2 processor, we find that a leading dimension
|
||||
of 22000 is a wise choice (hence 22000*22000*8). There will be another
|
||||
things resident in memory, so 22000 may not fit. If not, we can back
|
||||
off to 21000, or some other value as the largest problem.
|
||||
|
||||
For example, in a sample run of 5000, we observe on the output line (see below):
|
||||
|
||||
Maximum memory requested that can be used = 200104096, at the size = 5000
|
||||
|
||||
This corresponds to the actual size in bytes of the malloc performed by
|
||||
the benchmark and can be used to help guide the calculation of the
|
||||
largest problem.
|
||||
Once one has the largest problem, it is easier to fill out the rest of the
|
||||
data file given the information above.
