HPCmusic enables High Performance Computing in Music Production. We develop technologies that advance the future of music creation and reinvent the audience experience. Analogue tools, synthesizers, acoustic spaces and real instruments consist of complex frequency-dependent nonlinearities. To implement those features in a descrete-time system it is necessary to deploy advanced nonlinear differenti
al equations and mathematical transfer functions. For accurate emulation of significant nonlinearities in a virtual environment, the output of those equations may have significantly more bandwidth than the input signal. Moreover, audio streams use memory bandwidth and they are contiguous, which means 'they do not feet into caches' (Dr. Gerhard Lengelin) and this is another bottlenecks of virtual music production. Until today, the design and fidelity of those techniques were limited by computational resources and memory bandwidth. Supercomputing technologies along with proprietary advanced algorithms give us the necessary bandwidth and low latency to work with thousands of tracks, effect and unlimited polyphony in real time and at any sound quality level. VST developers can now implement highly advanced quality features and design genuine surround audio tools. HPCmusic grows organically, partnering of the best in class DSP developers from all around the world inside the largest computational ecosystem, the HPC Advisory Council, which includes more than 360 members and focuses on bridging the gap between high-performance computing use and its potential, bringing the beneficial capabilities of HPC to new users for better research, education, innovation and product manufacturing, and brings users the expertise needed to operate HPC systems, provide application designers with the tools needed to enable parallel computing, and to strengthen the qualification and integration of HPC system products. The HPC Advisory Council, a leading organization for high-performance computing research, outreach and education, announced the formation of the HPCmusic subgroup, an advanced research project that focuses on the usage of High-Performance Computing (HPC) to enable advancements in music creation, distribution and reproduction.
