Identifying dependencies in a control sequence for execution on a hardware accelerator

A system for identifying dependencies in a control sequence for execution on a hardware accelerator, the system comprising:

• a host processor configured to assign error dependency (EDEP) levels to control blocks;
• a control block storage queue configured to store the control blocks;
• and
• an EDEP processor configured to:
• receive a control block that comprises a first error dependency level;
• maintain the first EDEP level;
• determine whether the received control block was successfully executed;
• receive a subsequent control block that comprises a second EDEP level;
• compare the first EDEP level and the second EDEP level;
• and
• provide the subsequent control block for execution based at least in part on the successful execution of the received control block, and on the second EDEP level being less than or equal to the first EDEP level.

A computer program product for identifying dependencies in a control sequence for execution on a hardware accelerator, the computer program product comprising:

• a computer readable storage medium having stored thereon first program instructions executable by a processor to cause the processor to:
• receive a control block that comprises a first error dependency level;
• maintain the first EDEP level;
• determine whether the received control block was successfully executed;
• receive a subsequent control block that comprises a second EDEP level;
• compare the first EDEP level and the second EDEP level;
• and
• provide the subsequent control block for execution based at least in part on the successful execution of the received control block, and on the second EDEP level being less than or equal to the first EDEP level
