Abstract :
Plasma (ionized gas) is the most common state of the matter in the universe but relatively rare on Earth. The quest for the thermonuclear controlled fusion (as an energy source) depends on heating plasmas to temperatures around 10,000,000 Kelvin. The optimization of energy deposition in plasmas by heating them through RF waves in machines called tokamaks has been subject of thorough research (with intense numerical modeling). This work is embedded in this subject with main focus in the run time reduction for the ICANT code, which provides self-consistent calculation of RF current values in a heating antenna model. Typical assessment of an antenna model is made with several runs, each taking several hours, turning this task into daypsilas job. The parallelization was obtained and yielded the same results of the serial version with fair scalability (up to 10 nodes).
