- * \author Anoop Saldanha <anoopsaldanha@gmail.com>
- *
- * API has be introduced to allow buffering of data by multiple writers
- * asynronously. The current version only allows sequential reads.
- *
- * The API works by first registering a couple of buffers, which would
- * be sliced and allocated for use by the API to potential writers.
- *
- * The registration API requires 3 buffers to be registered. The data
- * buffer(d_buffer), into which the API buffers data, the pointer buffer
- * (p_buffer), which would hold the pointer var instance corresponding to
- * its entry in the d_buffer, and the offset buffer(o_buffer), which
- * holds an offset entry for the data corresponding to the pointer buffer
- * entry.
- *
- * A writer wishing to write data would be required to obtain a slice
- * using CudaBufferGetSlice. Once data has been written to the slice,
- * it can report back saying the slice has been written to by setting
- * a flag in the slice - SC_ATOMIC_SET(slice->done, 1).
- *
- * A reader wishing to retrieve the data written by writers, will do
- * so using the API call - CudaBufferCullCompletedSlices(). Once data
- * has been consumed, the reader would report back using
- * CudaBufferReportCulledConsumption() so that resources can be freed
- * to be reallocated to other writers.

-/**
- * \brief Allocates bytesize bytes of host memory that is page-locked and
- * accessible to the device. The driver tracks the virtual memory ranges
- * allocated with this function and automatically accelerates calls to
- * functions such as cuMemcpyHtoD(). Since the memory can be accessed
- * directly by the device, it can be read or written with much higher
- * bandwidth than pageable memory obtained with functions such as
- * SCMalloc(). Allocating excessive amounts of pinned memory may degrade
- * system performance, since it reduces the amount of memory available
- * to the system for paging. As a result, this function is best used
- * sparingly to allocate staging areas for data exchange between host
- * and device.
- *
- * The Flags parameter enables different options to be specified that
- * affect the allocation, as follows.
- *
- * - CU_MEMHOSTALLOC_PORTABLE: The memory returned by this call will be
- * considered as pinned memory by all CUDA contexts, not just the one
- * that performed the allocation.
- * - CU_MEMHOSTALLOC_DEVICEMAP: Maps the allocation into the CUDA
- * address space. The device pointer to the memory may be obtained by
- * calling cuMemHostGetDevicePointer(). This feature is available only
- * on GPUs with compute capability greater than or equal to 1.1.
- * - CU_MEMHOSTALLOC_WRITECOMBINED: Allocates the memory as write-combined
- * (WC). WC memory can be transferred across the PCI Express bus more
- * quickly on some system con?gurations, but cannot be read efficiently
- * by most CPUs. WC memory is a good option for buffers that will be
- * written by the CPU and read by the GPU via mapped pinned memory or
- * host->device transfers. All of these fags are orthogonal to one
- * another: a developer may allocate memory that is portable, mapped
- * and/or write-combined with no restrictions.
- *
- * The CUDA context must have been created with the CU_CTX_MAP_HOST flag
- * in order for the CU_MEMHOSTALLOC_MAPPED flag to have any effect.
- *
- * The CU_MEMHOSTALLOC_MAPPED flag may be specified on CUDA contexts for
- * devices that do not support mapped pinned memory. The failure is
- * deferred to cuMemHostGetDevicePointer() because the memory may be
- * mapped into other CUDA contexts via the CU_MEMHOSTALLOC_PORTABLE flag.
- *
- * The memory allocated by this function must be freed with cuMemFreeHost().
