Reducing data format conversion of an accelerator

A computer system for facilitating processing within a computing environment, the computer system comprising:

• a memory;
• and
• a processing circuit in communication with the memory, wherein the computer system is configured to perform a method, the method comprising:
• reducing data format conversion processing of an accelerator accessed by a processor of the computing environment, the processor and accelerator using different data formats, and the accelerator being configured to perform, in part, an input data format conversion to convert received data from a processor data format to an accelerator data format prior to performing an operation using the data, and an output data format conversion to convert resultant data from the accelerator data format back to the processor data format after performing the operation, the reducing comprising:
• determining that adjoining operations of a process to run on the processor and accelerator are to be performed by the accelerator, the adjoining operations including a source operation and a destination operation;
• based on the determining, identifying for removal, by setting respective convert parameters to FALSE, output data format conversion of output data of the source operation for input to the destination operation as input data, and input data format conversion of the input data for the destination operation;
• and
• wherein the reducing further comprises blocking, based on the respective convert parameters being set to FALSE, the output data format conversion of output data of the source operation for input to the destination operation as input data, and blocking the input data format conversion of the input data for the destination operation.
