Three‐dimensional laser wakefield acceleration (LWFA) simulations have recently been performed to benchmark the commonly used particle‐in‐cell (PIC) codes VORPAL, OSIRIS, and QuickPIC. The simulations were run in parallel on over 100 processors, using parameters relevant to LWFA with ultra‐short Ti‐Sapphire laser pulses propagating in hydrogen gas. Both first‐order and second‐order particle shapes were employed. We present the results of this benchmarking exercise, and show that accelerating gradients from full PIC agree for all values of and that full and reduced PIC agree well for values of approaching 4.
