Has anyone worked with the IEK-TM4C129EXL evaluation board?
Hey guys Has anyone worked with the IEK-TM4C129EXL evaluation board? If so, could you please share the necessary configurations or libraries required to develop on this board using Mbed OS?
Solution:
I wouldn't use Mbed OS anymore, they announced end of life in July 26. https://forums.mbed.com/t/important-update-on-mbed-end-of-life/23644
Debugging Numerical Instability in AVX512-Optimized 2D Fluid Simulation on x86-64 CPU
In the process of me optimizing a 2D fluid simulation for x86-64 CPU using AVX512 instructions, Intel Xeon architecture , scalable processor with AVX512 support, GCC 12 compiler with
-O3 optimization flags having periodic boundary conditions using explicit euler time stepping s heme I've implemented a staggered grid-based approach with a finite difference method for calculating fluid forces, but I'm encountering numerical instability issues when simulating large-scale fluid dynamics.
Here is my AVX512 optimized force calculation kernel...Solution:
@Marvee Amasi It sounds like you're running into stability issues with your fluid simulation, especially with the explicit
Euler scheme on a large grids, to address the numerical instability, try reducing the time step or switching to a more stable method like implicit Euler. Make sure your time step meets the CFL condition to avoid instability.
r-check your periodic boundary conditions for errors, and be cautious with AVX512 optimizations, as they can amplify floating-point precision issues. The Floating point exception could indicate division by zero or overflow, so make sure your calculations are well-guarded.
To debug, simplify your simulation or use tools like valgrind and gdb to catch errors. These steps should help stabilize your simulation....
Preventing "Target not responding" errors while plotting real-time MPU6050 data via ST-Link v3set
Hello Everyone,
I'm using ST-Link v3set with a custom build board. I'm trying to see the real time plotting of the angle measured with MPU6050.
The first few seconds everything works fine, but then I started to lose connection with the board "Target is not responding, retrying..." and the live expression stop working.
If I add a delay like HAL_Delay(500), it will work but it's just too slow to see the real time graph, decreasing it will cause the problem described above...
