The energy consumption of computer components when executing OpenCL programs

V diplomskem delu smo raziskali, kaj in v kolikšni meri vpliva na porabo električne energije računalniškega sistema, ki izvaja programsko kodo napisano v programskem jeziku OpenCL. Nekateri taki dejavniki so: čas izvajanja, število delovnih skupin, število zagnanih ščepcev in uporaba lokalnega pomnilnika. Predstavili smo dosedanja prizadevanja na tem področju in trende, ki se razvijajo. Opisali smo tudi programski jezik OpenCL in zakaj se ga uporablja. Predstavili smo sistem, na katerem se izvajajo meritve porabe električne energije, kako se merjenja električne energije nasploh lotimo in katera oprema se uporablja za izvajanje meritev. Predstavljene so tudi težave, vezane na programsko in strojno opremo in kako jih rešimo.We study what and to what extent the power consumption of computer systems is influenced by execution of different programs written in OpenCL programming language. Previous and current trends, that are developing in this field are described. Some identified factors are: running time, number of working groups, number of running kernels and use of local memory. OpenCL programming language and its uses are described. The thesis describes, how do we measure electrical energy in general and what equipment is being used. The computer system on which power measurements were performed is also introduced. Problems related to hardware, equipment and software, that we can encounter, and their solutions are presented as well
