Methods, systems and devices for recovering from corruptions in data processing units

A data processing unit (DPU) of a plurality of DPUs of a computing system without a central processing unit and each DPU communicatively coupled to a non-volatile memory, the DPU configured to:

• determine validity of an allocation table of the data processing unit;
• retrieve a first process descriptor from the allocation table;
• parse the non-volatile memory for a first set of process data corresponding to the first process descriptor;
• determine validity of the first set of process data corresponding to the first process descriptor;
• and
• attempt to recover the first set of process data in accordance with a determination that the first set of process data is invalid.

A method of maintaining allocation table data of a data processing unit (DPU) of a plurality of DPUs of a computing system without a central processing unit and each DPU communicatively coupled to a non-volatile memory, the method at the DPU comprising:

• determining validity of an allocation table of the DPU;
• retrieving a first process descriptor from the allocation table;
• parsing the non-volatile memory for a first set of process data corresponding to the first process descriptor;
• determining validity of the first set of process data corresponding to the first process descriptor;
• and
• initiating recovery of the first set of process data in accordance with a determination that the first set of process data is invalid.
