Detailed Description

Macro Definition Documentation

hipArrayDefault

#define hipArrayDefault   0x00

Default HIP array allocation flag.

hipDeviceMallocFinegrained

#define hipDeviceMallocFinegrained   0x1

Memory is allocated in fine grained region of device.

hipDeviceMallocUncached

#define hipDeviceMallocUncached   0x3

Memory allocated will be uncached.

hipDeviceScheduleAuto

#define hipDeviceScheduleAuto   0x0

Automatically select between Spin and Yield.

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.

hipEventInterprocess

#define hipEventInterprocess   0x4

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

#define hipExtHostRegisterCoarseGrained   0x8

Coarse Grained host memory lock.

hipHostMallocCoherent

#define hipHostMallocCoherent   0x40000000

Allocate coherent memory. Overrides HIP_COHERENT_HOST_ALLOC for specific allocation.

hipHostMallocDefault

#define hipHostMallocDefault   0x0

Default pinned memory allocation on the host.

hipHostMallocMapped

#define hipHostMallocMapped   0x2

Map the allocation into the address space for the current device. The device pointer can be obtained with hipHostGetDevicePointer.

hipHostMallocNonCoherent

#define hipHostMallocNonCoherent   0x80000000

Allocate non-coherent memory. Overrides HIP_COHERENT_HOST_ALLOC for specific allocation.

hipHostMallocNumaUser

#define hipHostMallocNumaUser   0x20000000

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.

hipHostRegisterDefault

#define hipHostRegisterDefault   0x0

Memory is Mapped and Portable.

hipHostRegisterIoMemory

#define hipHostRegisterIoMemory   0x4

Not supported.

hipHostRegisterMapped

#define hipHostRegisterMapped   0x2

hipHostRegisterPortable

#define hipHostRegisterPortable   0x1

Memory is considered registered by all contexts.

hipMallocSignalMemory

#define hipMallocSignalMemory   0x2

Memory represents a HSA signal.

hipMemAttachGlobal

#define hipMemAttachGlobal   0x01

Memory can be accessed by any stream on any device

hipMemAttachHost

#define hipMemAttachHost   0x02

Memory cannot be accessed by any stream on any device.

hipMemAttachSingle

#define hipMemAttachSingle   0x04

Memory can only be accessed by a single stream on the associated device.

hipStreamDefault

#define hipStreamDefault   0x00

Default stream creation flags. These are used with hipStreamCreate().

hipStreamNonBlocking

#define hipStreamNonBlocking   0x01

Stream does not implicitly synchronize with null stream.

hipStreamPerThread

#define hipStreamPerThread   ((hipStream_t)2)

Implicit stream per application thread.
