Scheduling of Execution Units

A system, comprising:

• memory;
• and
• processor coupled to the memory, wherein the processor executes operations, the operations comprising:
• (i) requesting, by an execution unit, additional execution time from a kernel to prevent the execution unit from being swapped out during an execution of a critical section;
• (ii) determining, by the kernel, whether the execution unit has previously avoided yielding execution to other execution units within a predetermined period of time after being allocated the additional execution time in response to at least one previous request for the additional execution time;
• and
• (iii) allocating, by the kernel, the additional execution time to the execution unit, in response to determining that the execution unit has not previously avoided yielding execution to the other execution units within the predetermined period of time after being allocated the additional execution time in response to the at least one previous request for the additional execution time.

An article of manufacture, wherein the article of manufacture is capable of causing operations on a computer, the operations comprising:

• requesting, by an execution unit, additional execution time from a kernel to prevent the execution unit from being swapped out during an execution of a critical section;
• determining, by the kernel, whether the execution unit has previously avoided yielding execution to other execution units within a predetermined period of time after being allocated the additional execution time in response to at least one previous request for the additional execution time;
• and
• allocating, by the kernel, the additional execution time to the execution unit, in response to determining that the execution unit has not previously avoided yielding execution to the other execution units within the predetermined period of time after being allocated the additional execution time in response to the at least one previous request for the additional execution time.

A method for deploying computing infrastructure, comprising integrating computer-readable code into a computer, wherein the code in combination with the computer is capable of performing:

• requesting, by an execution unit, additional execution time from a kernel to prevent the execution unit from being swapped out during an execution of a critical section;
• determining, by the kernel, whether the execution unit has previously avoided yielding execution to other execution units within a predetermined period of time after being allocated the additional execution time in response to at least one previous request for the additional execution time;
• and
• allocating, by the kernel, the additional execution time to the execution unit, in response to determining that the execution unit has not previously avoided yielding execution to the other execution units within the predetermined period of time after being allocated the additional execution time in response to the at least one previous request for the additional execution time.
