◆ hipDeviceScheduleMask

#define hipDeviceScheduleMask   0x7

◆ hipDeviceScheduleSpin

#define hipDeviceScheduleSpin   0x1

Dedicate a CPU core to spin-wait. Provides lowest latency, but burns a CPU core and may consume more power.

◆ hipDeviceScheduleYield

#define hipDeviceScheduleYield   0x2

Yield the CPU to the operating system when waiting. May increase latency, but lowers power and is friendlier to other threads in the system.

◆ hipEventBlockingSync

#define hipEventBlockingSync   0x1

Waiting will yield CPU. Power-friendly and usage-friendly but may increase latency.

◆ hipEventDefault

#define hipEventDefault   0x0

Default flags.

◆ hipEventDisableTiming

#define hipEventDisableTiming   0x2

Disable event's capability to record timing information. May improve performance.

Event can support IPC. hipEventDisableTiming also must be set.

◆ hipEventReleaseToDevice

#define hipEventReleaseToDevice   0x40000000

Use a device-scope release when recording this event. This flag is useful to obtain more precise timings of commands between events. The flag is a no-op on CUDA platforms.

◆ hipEventReleaseToSystem

#define hipEventReleaseToSystem   0x80000000

Use a system-scope release when recording this event. This flag is useful to make non-coherent host memory visible to the host. The flag is a no-op on CUDA platforms.

◆ hipExtAnyOrderLaunch

#define hipExtAnyOrderLaunch   0x01

AnyOrderLaunch of kernels.

◆ hipExtHostRegisterCoarseGrained

Host memory allocation will follow numa policy set by user.

◆ hipHostMallocPortable

#define hipHostMallocPortable   0x1

Memory is considered allocated by all contexts.

◆ hipHostMallocWriteCombined

#define hipHostMallocWriteCombined   0x4

Allocates the memory as write-combined. On some system configurations, write-combined allocation may be transferred faster across the PCI Express bus, however, could have low read efficiency by most CPUs. It's a good option for data tranfer from host to device via mapped pinned memory.

Stream does not implicitly synchronize with null stream.

◆ hipStreamPerThread

#define hipStreamPerThread   ((hipStream_t)2)

Implicit stream per application thread.

◆ hipStreamWaitValueAnd

#define hipStreamWaitValueAnd   0x2

◆ hipStreamWaitValueEq

#define hipStreamWaitValueEq   0x1

◆ hipStreamWaitValueGte

#define hipStreamWaitValueGte   0x0
