This contains results for various versions of MAGMA, CUDA, and GPU cards.
Routines currently tested are:
getrf, getrf_gpu
potrf, potrf_gpu -- lower
geqrf, geqrf_gpu -- square
geev -- no vectors, vectors
sy/heev, sy/heev_gpu -- no vectors, vectors
sy/heev_2stage -- no vectors, vectors
gesvd -- no vectors, some vectors; square, 3:1, 1:3, 100:1, 1:100
gesdd -- no vectors, some vectors; square, 3:1, 1:3, 100:1, 1:100
symv -- lower, upper
TODO
extend potrf to upper
extend symv to upper
extend geqrf to tall, wide
For most routines, this standard set of sizes is used:
small: --range 10:90:10
medium: --range 100:900:100
large: --range 1000:9000:1000
xlarge: --range 10000:20000:2000
For SVD, also tests 3:1, 1:3, 100:1, 1:100 ratios.
For symv, the small, medium, large ranges use steps of 1, 10, 100, respectively.
Running tests
=============
To compile MAGMA for running tests, use one of these make.inc files:
make.inc.mkl-icc-ilp64 (preferred) or
make.inc.mkl-ilp64 (older versions, with gcc).
To run tests, use include run*.csh scripts.
Each should generate [sdcz]xxxx.txt output files.
./run_amigos.csh
ls [sdcz]*.txt
cgeqrf.txt dgeqrf.txt sgeqrf.txt zgeqrf.txt
cgetrf.txt dgetrf.txt sgetrf.txt zgetrf.txt
cpotrf.txt dpotrf.txt spotrf.txt zpotrf.txt
For local tests, simply parse data into local.py, which plots.py automatically
loads.
./parse.py [sdcz]*.txt > local.py
You may want to edit the version, device, and cpu meta-data in local.py.
Archiving results
=================
For archive purposes, output is stored in the hierarchy below. To document
results, please store the setup.txt and make.inc files, in addition to data
files.
magma version
cuda version-gpu model
setup.txt (host, GPU, CPU, gcc version, etc.)
make.inc
[sdcz]{getrf,potrf,...}.txt
Example:
v1.6.0
cuda7.0-k40c
setup.txt
make.inc
sgetrf.txt
dgetrf.txt
cgetrf.txt
zgetrf.txt
etc.
Parse the data into a Python data file, named for the version information.
./parse.py v1.6.0/cuda7.0-k40c/*.txt > v160_cuda70_k40c.py
In that Python data file, you need to edit the GPU and CPU information. These
should be set to match existing data files using the same hardware:
version = '1.6.0'
cuda = '7.0'
device = 'Kepler K40c' # <== change
cpu = '2x8 core Sandy Bridge E5-2670' # <== change
Add the data file to parse.py:
import v150_cuda70_k40c
import v160_cuda70_k40c # <== add
versions = [
v150_cuda70_k40c,
v160_cuda70_k40c, # <== add
]
Add both the Python data file and the raw data files to SVN.
svn add v160_cuda70_k40c.py
svn add v1.6.0/
Plotting results
================
The plots.py Python script plots the performance of various routines from
different versions of MAGMA. It requires matplotlib (pyplot).
plots.versions is an array of available MAGMA versions; use array slices, as
shown below, to select which versions to plot.
plots.help() prints the global settings and available plots.
It is easiest to use plots.py from an interactive Python shell. IPython is
recommended.
Example using ipython:
mint magma-trunk/results> ipython
>>> run -i plots # this prints help; -i is necessary so g_save, etc. are in the right name space to be modified
Available versions:
versions[0] = 1.5.0
versions[1] = 1.6.0
versions[2] = 1.6.1
versions[3] = 1.6.2
versions[4] = 1.7.0
>>> plot_potrf( versions[ 4 ] ) # index 4 (1.7.0) only
>>> plot_potrf( versions[ 2: ] ) # index 2 (1.6.1) and later
>>> g_save = True # save PDF files
>>> g_subplots = False # plot precisions as 4 figures instead of 4 subplots
>>> plot_potrf( versions[ [0,2,4] ] ) # index 0 (1.5.0), 2 (1.6.1), and 4 (1.7.0)

Using regular python:
magma-trunk/results> python
>>> import plots # this prints help
>>> plots.g_save = True
>>> plots.plot_getrf( plots.versions[ [0,2,4] ] )
saving getrf.pdf
>>> plots.g_subplots = False
>>> plots.plot_getrf( plots.versions[ [0,2,4] ] )
saving sgetrf.pdf
saving dgetrf.pdf
saving cgetrf.pdf
saving zgetrf.pdf
>>> plots.help()
Global settings:
g_save # True to save plots as PDF files
g_subplots # True for all 4 precisions as subplots in one figure, False for 4 separate figures
g_log # True for semilogx, False for linear plot
g_figsize # size of figure with 4-up subplots, default (9,7)
g_figsize2 # size of individual figures, default (6,4)
Available plots:
plot_getrf( versions, lapack=True, cpu=True, gpu=True )
plot_potrf( versions, lapack=True, cpu=True, gpu=True )
plot_geqrf( versions, lapack=True, cpu=True, gpu=True )
plot_geev( versions, lapack=True )
plot_syev( versions, lapack=True, cpu=True, gpu=True, bulge=True )
plot_gesvd( versions, lapack=True, svd=True, sdd=True, ratio=1 )
where ratio m:n in { 1, 3, 100, 1/3., 1/100. }
plot_symv( versions, lapack=True )
plot_all( versions, lapack=True, cpu=True, gpu=True, bulge=True, sdd=True, svd=True, ratio=1 )
Available versions:
versions[0] = 1.5.0
versions[1] = 1.6.0
versions[2] = 1.6.1
versions[3] = 1.6.2
versions[4] = 1.7.0
