Defines

GA_CTX_PROP_DEVNAME

Get the device name for the context.

Type: char [256]

GA_CTX_PROP_MAXLSIZE

Get the maximum block size (also known as local size) for a kernel call in the context.

Type: size_t

GA_CTX_PROP_LMEMSIZE

Get the local memory size available for a call in the context.

Type: size_t

GA_CTX_PROP_NUMPROCS

Number of compute units in this context.

compute units times local size is more or less the expected parallelism available on the device, but this is a very rough estimate.

Type: unsigned int

GA_CTX_PROP_MAXGSIZE

Get the maximum group size for a kernel call in this context.

Type: size_t

GA_CTX_PROP_BLAS_OPS

Get the vector of blas ops for the context.

This may differ from one context to the other in the same backend depending of the availability and performance of various BLAS libraries.

Type: const gpuarray_blas_ops *

GA_CTX_PROP_BIN_ID

Get the compatibility ID for the binaries generated with this context.

Those binaries should work with any context which has the same ID.

Type: const char *

GA_CTX_PROP_ERRBUF

Get a pre-allocated 8 byte buffer for kernel ops.

This buffer is initialized to 0 on allocation and must always be returned to that state after using it.

This only to avoid the overhead of an allocation when calling a kernel that may error out. It does not preclude the need for synchronization and transfers.

Type: gpudata *

GA_CTX_PROP_TOTAL_GMEM

Get the total size of global memory on the device.

Type: size_t

GA_CTX_PROP_FREE_GMEM

Get the size of free global memory on the device.

Type: size_t

GA_CTX_PROP_NATIVE_FLOAT16

Get the status of native float16 support on the device.

Type: int

GA_CTX_PROP_MAXGSIZE0

Get the maximum global size for dimension 0.

Type: size_t

GA_CTX_PROP_MAXGSIZE1

Get the maximum global size for dimension 1.

Type: size_t

GA_CTX_PROP_MAXGSIZE2

Get the maximum global size for dimension 2.

Type: size_t

GA_CTX_PROP_MAXLSIZE0

Get the maximum local size for dimension 0.

Type: size_t

GA_CTX_PROP_MAXLSIZE1

Get the maximum local size for dimension 1.

Type: size_t

GA_CTX_PROP_MAXLSIZE2

Get the maximum loca size for dimension 2.

Type: size_t

GA_CTX_PROP_COMM_OPS

Get the vector of collective ops for the context.

Type: const gpuarray_comm_ops *

GA_CTX_PROP_PCIBUSID

Get the device PCI Bus ID for the context.

Type: char [16]

GA_CTX_PROP_LARGEST_MEMBLOCK

Get the largest single block of memory that can be allocted.

Type: size_t

GA_BUFFER_PROP_START
GA_BUFFER_PROP_CTX

Get the context in which this buffer was allocated.

Type: gpucontext *

GA_BUFFER_PROP_REFCNT

The reference count of the buffer. Use only for debugging purposes.

Type: unsigned int

GA_BUFFER_PROP_SIZE

Size of the buffer on the device.

This may be larger than the requested allocation size due to a number of factors.

Type: size_t

GA_KERNEL_PROP_START
GA_KERNEL_PROP_CTX

Get the context for which this kernel was compiled.

Type: gpucontext *

GA_KERNEL_PROP_MAXLSIZE

Get the maximum block size (also known as local size) for a call of this kernel.

Type: size_t

GA_KERNEL_PROP_PREFLSIZE

Get the prefered multiple of the block size for a call to this kernel.

Type: size_t

GA_KERNEL_PROP_NUMARGS

Get the number of kernel arguments.

Type unsigned int

GA_KERNEL_PROP_TYPES

Get the list of argument types for a kernel.

This list is the same length as the number of arguments to the kernel. Do not modify the returned list.

Type: const int *
