Struct rustacuda::context::ContextFlags [−][src]
pub struct ContextFlags { /* fields omitted */ }
Expand description
Bit flags for initializing the CUDA context.
If you’re not sure which flags to use, MAP_HOST | SCHED_AUTO
is a good default.
Implementations
Instructs CUDA to actively spin when waiting for results from the GPU. This can decrease latency when waiting for the GPU, but may lower the performance of other CPU threads if they are performing work in parallel with the CUDA thread.
Instructs CUDA to yield its thread when waiting for results from the GPU. This can increase latency when waiting for the GPU, but can increase the performance of CPU threads performing work in parallel with the GPU.
Instructs CUDA to block the CPU thread on a synchronization primitive when waiting for the GPU to finish work.
Instructs CUDA to automatically choose whether to yield to other OS threads while waiting for the GPU, or to spin the OS thread. This is the default.
Instructs CUDA to support mapped pinned allocations. This flag must be set in order to use page-locked memory (see LockedBuffer).
Instruct CUDA not to reduce local memory after resizing local memory for a kernel. This can prevent thrashing by local memory allocations when launching many kernels with high local memory usage at the cost of potentially increased memory usage.
Returns an empty set of flags
Returns the set containing all flags.
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Returns true
if there are flags common to both self
and other
.
Returns true
all of the flags in other
are contained within self
.
Inserts the specified flags in-place.
Removes the specified flags in-place.
Toggles the specified flags in-place.
Inserts or removes the specified flags depending on the passed value.
