>>History
Advanced Simulation Library is being developed by Avtech Scientific, an Israeli company. Its `F33f`_`[source code`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Source_code]`_`f was released to the community on 14 May 2015, whose members packaged it for scientific sections of all major `F33f`_`[Linux`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Linux]`_`f distributions shortly thereafter.`:cite-ref-2[`F5bf`_`[2`#cite-note-2]`_`f]`:cite-ref-3[`F5bf`_`[3`#cite-note-3]`_`f]`:cite-ref-4[`F5bf`_`[4`#cite-note-4]`_`f]`:cite-ref-5[`F5bf`_`[5`#cite-note-5]`_`f]`:cite-ref-6[`F5bf`_`[6`#cite-note-6]`_`f]`:cite-ref-7[`F5bf`_`[7`#cite-note-7]`_`f] Subsequently, `F33f`_`[Khronos Group`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Khronos_Group]`_`f acknowledged the significance of ASL and listed it on its website among OpenCL-based resources.`:cite-ref-8[`F5bf`_`[8`#cite-note-8]`_`f]

• Mesh-free, immersed boundary approach allows users to move from CAD directly to computations reducing pre-processing effort
• Dynamic compilation enables an additional layer of optimization at run-time (i.e. for a specific parameters set the application was provided with)
• Automatic hardware acceleration and parallelization of applications
• Deployment of same program on a variety of parallel architectures - GPU, APU, FPGA, DSP, multicore CPUs
• Ability to deal with complex boundaries
