System and method for handling cross-platform system call in a hybrid system

A computer program product, comprising a computer usable storage medium having a computer readable program code embodied therein, said computer readable program code containing instructions that when executed by a processor of a computer system implement a method for handling a system call in a hybrid system, the method comprising:

• receiving a request to execute the system call from a user application running on a first computer system, wherein the system call provides a kernel service upon being executed, wherein the hybrid system comprises the first computer system and a second computer system, the first computer system comprising the user application and a first kernel, the second computer system comprising a second kernel, and wherein the first kernel is coupled to the second kernel;
• discovering that the system call is predetermined to be remotely executed on the second computer system of the hybrid system;
• converting the system call into a second configuration that is compatible with the second computer system such that the second kernel executes the converted system call to provide the kernel service to the user application;
• transferring the converted system call to the second kernel;
• obtaining a result of executing the converted system call, wherein the result is produced by the second kernel;
• adjusting the obtained result to generate an adjusted result such that the adjusted result is in a first configuration that is compatible with the first computer system;
• and
• sending the adjusted result to the user application that had sent the request,
• wherein said receiving, said discovering, said converting, said transferring, said obtaining, said adjusting, and said sending are performed by the first kernel.

A system comprising a processor and a computer readable memory unit coupled to the processor, said memory unit containing instructions that when executed by the processor implement a method for handling a system call in a hybrid system, the method comprising:

• receiving a request to execute the system call from a user application running on a first computer system, wherein the system call provides a kernel service upon being executed, wherein the hybrid system comprises the first computer system and a second computer system, the first computer system comprising the user application and a first kernel, the second computer system comprising a second kernel, and wherein the first kernel is coupled to the second kernel;
• discovering that the system call is predetermined to be remotely executed on the second computer system of the hybrid system;
• converting the system call into a second configuration that is compatible with the second computer system such that the second kernel executes the converted system call to provide the kernel service to the user application;
• transferring the converted system call to the second kernel;
• obtaining a result of executing the converted system call, wherein the result is produced by the second kernel;
• adjusting the obtained result to generate an adjusted result such that the adjusted result is in a first configuration that is compatible with the first computer system;
• and
• sending the adjusted result to the user application that had sent the request,
• wherein said receiving, said discovering, said converting, said transferring, said obtaining, said adjusting, and said sending are performed by the first kernel.
