vx_start.S: Swizzle stack space
...
Striding stack space for threads by power-of-two risks possibilities of bank
conflicts or cache aliasing problems. Add an extra offset of 4 bytes to avoid
this.

Write vx_spawn_tasks_cluster
...
This scheduling logic tries to evenly distribute warps across *all* cores,
instead of trying to fill up the first cores as much as possible. This scheme
is necessary for the intra-cluster cores which are assumed to have equal
workloads distributed.
