Magnetars exhibit regular gamma-ray flares that are preceded by star quakes or glitches in the pulsations. The largest flares have L ~ 10^47 erg/s (3 since 1979).
No natural explanation for (1) sudden stop of activity P ~ 12 sec and (2) AXP-SNR association but no SGR-SNR association
Thompson & Duncan (1990's) – developed a … Continue Reading ››

Matt Kinsey: Porting the 2D Wave Equation to the GPU

Optimal number of threads per block is 32*n-1, where n is an integer. The best performance in the example shown was 63 threads per block.
Minimum number of blocks per grid is 32, according to the user's guide.
Every time a kernel is called, the memory needs to … Continue Reading ››
