v1.2.3

Multiple kernel names in "device to device pipeline stages" can be grouped with "@" separator instead of " ",",",";" separators so they read inputs from host only once before first kernel and write output to host only once after last kernel. Without "@", each kernel reads and writes inputs and outputs, making "multiple kernel stage" slower.

"@" separated kernels run as a single kernel so all use single global-local range value.

"a@b@c" N : 256 1 read 1 write

"a b@c" N,M : 256,128 2 reads 2 writes

v1.2.2

Now device to device pipeline stages can be initialized in buildPipeline() method with the parameters given in this method:

stage.initializerKernel("kernelName", new int[] { N }, new int[] { 256 });

v1.2.1

decreased command queue consumption per "device to device pipeline stage" to have room for more stages.

v1.2.0_hotfix

fixed: "result ready" boolean value returned by pipeline.pushData() is true at wrong iteration

v1.2.0

Compatible only with CekirdeklerCPP v1.2.0+

• Removed "Copy Memory" dependency,

• Added device to device pipelining feature

• Added helper methods normalizedGlobalRangesOfDevices(int id) and normalizedComputePowersOfDevices() in number cruncher class for querying from client code.

v1.1.9

array of user-defined structs can be wrapped by ClArray of type byte with its static method wrapArrayOfStructs

for example, Unity's Vector3

v1.1.8

Fixed unnecessary array bounds checking for read-only buffers. Those don't need a minimum length. They are copied as a whole at once.

Added minor documentation.

Added base of built-in auxilliary kernel function example (but not working yet)

v1.1.7

• added nbody(benchmark based) device reordering to enable picking fastest nbody performing device:

       Cekirdekler.Hardware.ClPlatforms platforms = Cekirdekler.Hardware.ClPlatforms.all();
       var selectedDevices = platforms.platformsAmd().devicesAmd().devicesWithHighestDirectNbodyPerformance();
  

• fixed minor bug in load balancer that triggered when number of devices are changed.

• added minor documentation

v1.1.6_hotfix

Deleted console size changing codes from platform / device info output methods. Those were not working for non-console apps.

v1.1.6

English translation of cluster computing related classes complete.

fixed some class file names.
