GPUs to Mars: Full-Scale Simulation of SpaceX's Mars Rocket Engine
About | Information | History | Online | Facts | Discovery
In this video presentation from the GPU Technology Conference, Stephen Jones and Adam Lichtl from SpaceX present: GPUs to Mars: Full-Scale Simulation of SpaceX's Mars Rocket Engine. "SpaceX is designing a new, methane-fueled engine powerful enough to lift the equipment and personnel needed to colonize Mars. A vital aspect of this effort involves the creation of a multi-physics code to accurately model a running rocket engine. The scale and complexity of turbulent non-premixed combustion has so far made it impractical to simulate, even on today's largest supercomputers. We present a novel approach using wavelets on GPUs, capable of capturing physics down to the finest turbulent scales."

If you study Electrical engineering and you used 3D modeling before, you know why this is an awesome breakthrough in technology. It offers unprecedented level of details right where it matters.
Great video, very glad it was shared on the internet. -
What a load af fucking bollocks.

Did he say founded in 2012 at 1:48?

Great presentation, awesome technology, beautiful modeling.

This video is by far theeeeeee best I seen on YouTube in a long long long time. So there is nothing I can do but put among the tabs and watch it all over again.
I done a lot of computer programming in my life. I watch all kind of documentaries every day on YouTube physics, military, history u name it.. In this video they had the balls not to dumb it down. I loved it. BTW B+ -trees are from database sorting on really weak computers back in 1970s and 1980s. B+ trees dont get so deep as B-trees. Makes the data align in chunks in memory ready to be written in bulk to disk. In that applicaiton the B-tree page size usually match the system OS page size. -
Now, KSP should use this to calculate and render its physics.

..."so anyone who has played kerbal space program has seen this..." lel I agree
-
Quantum computer available anyone?
-
cool presentation Redhat
so TL;DW: a realtime CFD sim of that much data output with current GPU and storage tech (even if it's some kind of 10,000 disk RAID SSD array) anytime soon... is not happening -
i want a silicon valley episode about this

starlite - https://en.wikipedia.org/wiki/Starlite ''Starlite is a material claimed to be able to withstand and insulate from extreme heat ''
dose anyone one know if this materiel is used on any modern rocket or actually thing ? anyone know if spaceX has ever used or experimented with it -
Impressive is almost an understatement ! Thanks for posting.

Selamat kerja team semua disana .

Great video! Nostalgically recall the master degree times

1% atmosphere...
If my calculations are right, that means that it's roughly equivalent to the pressure on Earth at 30 km in altitude? (or at 100,000 feet for you non-metric boys) -
have partical accelerators been used to experment with hypergolic chemical thermal expansion ratios temperature after basic particle research for temperature pressure and raio of mix resaearch...also suggest a model of observation in sunspot rims from subnspot surface gases combine in extreme burns..number of reactions reviewed by xray defraction and spectromiters.

I have a feeling that we still could use a "catapult" type system in extremely large rockets, similar to what an aircraft carrier use. The amount of thrust needed for the "first" lift is significantly larger than what the engines need to for the rest of the flight.
