Expand description

\brief Returns resource limits

Returns in \p *pvalue the current size of \p limit. The supported ::CUlimit values are:

  • ::CU_LIMIT_STACK_SIZE: stack size in bytes of each GPU thread.
  • ::CU_LIMIT_PRINTF_FIFO_SIZE: size in bytes of the FIFO used by the ::printf() device system call.
  • ::CU_LIMIT_MALLOC_HEAP_SIZE: size in bytes of the heap used by the ::malloc() and ::free() device system calls.
  • ::CU_LIMIT_DEV_RUNTIME_SYNC_DEPTH: maximum grid depth at which a thread can issue the device runtime call ::cudaDeviceSynchronize() to wait on child grid launches to complete.
  • ::CU_LIMIT_DEV_RUNTIME_PENDING_LAUNCH_COUNT: maximum number of outstanding device runtime launches that can be made from this context.
  • ::CU_LIMIT_MAX_L2_FETCH_GRANULARITY: L2 cache fetch granularity.
  • ::CU_LIMIT_PERSISTING_L2_CACHE_SIZE: Persisting L2 cache size in bytes
