• Cuda CUDA_ERROR_INVALID_CONTEXT when calling cuMemGetInfo

  
  The Blog of Steven Mark Ford — Authority: 97
  Problem Calling cuMemGetInfo returns the result 201 (CUDA_ERROR_INVALID_CONTEXT) Cause The most common cause is that a context has not been initialised on the current host thread. Solution In your host application before calling cuMemGetInfo make a once off call to create a context. For an example of this ...

• A four-door Plymouth Barracuda’?

  
  Ride Lust - Motion + Mobility — Authority: 117
  Remember back in 2005 when the redesigned Dodge Charger came out? Mopar purists went completely bat-shit because Chrysler decided to give it four doors instead of two, which for some, was shear blasphemy. But what if back in the day the original Charger came with 4-doors? I mean that would have relegated it to family ...

• Solving Bivariate Polynomial Systems on a GPU

  
  GPU Science — Authority: 419
  We present a CUDA implementation of dense multivariate polynomial arithmetic based on Fast Fourier Transforms (FFT) over finite fields. Our core routine computes on the device (GPU) the subresultant chain of two polynomials with respect to a given variable. This subresultant chain is encoded by values on a FFT grid ...

• Development of parallel explicit finite element sheet forming simulation system based on GPU architecture

  
  GPU Science — Authority: 419
  Sheet forming simulation is very important for vehicle body design. Due to the increase of complexity and scale of the CAE model, a tradeoff between the accuracy and efficiency become the bottleneck for application. Therefore, a parallel explicit finite element (FE) based on graphics processing unit (GPU) architecture ...
