     5Old Hardware Benchmarks Running UCSF Chimera

     7
     8<p>
     9There are two types of benchmarks: the volume benchmarks and the molecule benchmarks.
     10
     11<h3>Volume benchmarks</h3>
     12
     13<p>
     14The volume scores (Surface, Mesh, Contour, Solid, Recolor)
     15give the edge size of a cube shaped volume data array such that
     16rendering or contouring or recoloring can be performed 10 times per second.
     17Data of this size can be easily manipulated in Chimera.
     18</p>
     19
     20<p>
     21Doubling a surface or mesh rendering score means rendering 4 times as
     22many triangles or lines per second.  Doubling a contouring, solid rendering
     23or solid recoloring score means processing 8 times as many data points
     24per second.
     25</p>
     26
     27<h3>Molecule benchmarks</h3>
     28<p>
     29The molecule scores (Null, Wire, Stick, BStick, Ribbon, Sphere, Ops)
     30give the frames-per-second for a given molecule and representation.
     31(See the
     32<a href="http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/benchmark/benchmark.html">benchmark extension</a>
     33documentation for details.)
     34
     35
     36<h3>Benchmark Extension</h3>
     37
     38<p>
     39The
     40<a href="http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/benchmark/benchmark.html">benchmark extension</a>
     41can be started from the Tools/Utilities/Benchmark menu entry.
     42If you send us
     43(<a href="mailto:chimera-users@cgl.ucsf.edu">chimera-users@cgl.ucsf.edu</a>)
     44your scores and machine information, we will include them in the table below.
     45</p>
     46
     47<h3>
     48Scores for Chimera Versions &gt;= 1892
     49</h3>
     50
     51<font color=red>
     52<p>
     53
     54Some of these scores are incorrect high values.  Prior to 1.2509 Chimera version the benchmark code did not draw the models to the screen in
     55in order to avoid syncronization to the display refresh rate (common with old
     56CRT displays).  Some
     57drivers were able to take advantage of this and shortcut the
     58full rendering giving incorrect timings.

     1474Textures must have power of 2 sizes.  Going from size 256 to 257 makes
     1475the 2 dimensional textures jump from size 256 by 256 to 512 by 512.  The
     1476bigger textures may not fit in texture memory reducing performance
     1477significantly.  A better implementation could render a data set with
     1478edge size 257 using several smaller blocks to avoid this big jump in
     1479performance.

     1486These systems have a bug in the OpenGL implementation where glPixelMap()
     1487does not work when loading a texture.  A fix to work around the problem
     1488was put into Chimera 1522 but the speed of changing thresholds in colormap
     1489solid rendering is compromised.
     1490The colormap solid rendering is not tested by the benchmarks but is the
     1491default solid rendering mode in the Chimera volume viewer extension.
     1492No data is shown in colormap solid mode on these (pre 1522) systems,
     1493but an outline box can be seen and rotated normally.
     1494The colormap mode can be turned off in the volume viewer options panel.
     1495The direct RGBA texture filling mode is then used which is slower when
     1496changing thresholds.

     1512Mesa is a software implementation of OpenGL.
     1513It does not use hardware acceleration provided by the graphics card.
     1514The scores for systems using Mesa are probably determined by computer
     1515CPU speed rather than graphics card performance.

     1565Chimera 1602 for Windows appears to have had the contouring code
     1566compiled without optimization making it 5 times slower to calculate
     1567isosurfaces than version 1516.  This effects the speed of the volume
     1568viewer extension.

     1593Surface and mesh rendering is about a factor of 3 faster on GeForce4
     1594cards with early 2003 drivers (4191 linux) if display lists are
     1595limited to less than about 64K triangles or lines.  I couldn't find
     1596anything on the web describing this.  I changed the Chimera isosurface

     1604The contouring benchmark was bottle-necked by slow STL::map<> behaviour.
     1605This was especially severe on Windows.  The map was used to avoid making
     1606multiple copies of triangle vertices.  A more efficient array based method
     1607increased the calculation speed by a factor of 3 for a 100^3 grid on most
     1608platforms, and a factor of 10 on Windows.
     1609Larger grids benefit less from this optimization.
