NAME¶
clCreateProgramWithBinary - Creates a program object for a context, and loads the binary bits specified by binary into the program object.¶
cl_program
clCreateProgramWithBinary(cl_context context,
cl_uint num_devices,
const cl_device_id *device_list,
const size_t *lengths,
const unsigned char **binaries,
cl_int *binary_status,
cl_int *errcode_ret);
PARAMETERS¶
contextMust be a valid OpenCL context.
device_list
A pointer to a list of devices that are in
context. device_list must be a non-NULL value. The binaries are
loaded for devices specified in this list.
num_devices
The number of devices listed in device_list.
The devices associated with the program object will be the list of devices
specified by device_list. The list of devices specified by
device_list must be devices associated with context.
lengths
An array of the size in bytes of the program binaries to
be loaded for devices specified by device_list.
binaries
An array of pointers to program binaries to be loaded for
devices specified by device_list. For each device given by
device_list[i], the pointer to the program binary for that device is
given by binaries[i] and the length of this corresponding binary is
given by lengths[i]. lengths[i] cannot be zero and
binaries[i] cannot be a NULL pointer.
The program binaries specified by binaries contain the bits that describe
one of the following:
binary_status
• a program executable to be run on the device(s)
associated with context.
• a compiled program for device(s) associated with
context.
• a library of compiled programs for device(s)
associated with context.
The program binary can consist of either or both of device-specific code and/or
implementation-specific intermediate representation (IR) which will be
converted to the device-specific code.Returns whether the program binary for each device
specified in device_list was loaded successfully or not. It is an array
of num_devices entries and returns CL_SUCCESS in
binary_status[i] if binary was successfully loaded for device specified
by device_list[i]; otherwise returns CL_INVALID_VALUE if
lengths[i] is zero or if binaries[i] is a NULL value or
CL_INVALID_BINARY in binary_status[i] if program binary is not a
valid binary for the specified device. If binary_status is NULL, it is
ignored.
errcode_ret
Returns an appropriate error code. If errcode_ret
is NULL, no error code is returned.
NOTES¶
OpenCL allows applications to create a program object using the program source or binary and build appropriate program executables. This can be very useful as it allows applications to load program source and then compile and link to generate a program executable online on its first instance for appropriate OpenCL devices in the system. These executables can now be queried and cached by the application. Future instances of the application launching will no longer need to compile and link the program executables. The cached executables can be read and loaded by the application, which can help significantly reduce the application initialization time.ERRORS¶
Returns a valid non-zero program object and errcode_ret is set to CL_SUCCESS if the program object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret:•CL_INVALID_CONTEXT if context is not a
valid context.
•CL_INVALID_VALUE if device_list is NULL or
num_devices is zero;
•CL_INVALID_DEVICE if OpenCL devices listed in
device_list are not in the list of devices associated with
context.
•CL_INVALID_VALUE if or if lengths or
binaries are NULL or if any entry in lengths[i] or
binaries[i] is NULL.
•CL_INVALID_BINARY if an invalid program binary
was encountered for any device. binary_status will return specific
status for each device.
•CL_OUT_OF_RESOURCES if there is a failure to
allocate resources required by the OpenCL implementation on the device.
•CL_OUT_OF_HOST_MEMORY if there is a failure to
allocate resources required by the OpenCL implementation on the host.
