Handling system calls during execution of an application over a plurality of nodes

A system for executing an application over a plurality of nodes each including a hardware platform, the system comprising:

• a first node including a first processor and a first memory and having a first runtime environment and a first application monitor that are being executed in the first processor, the first runtime environment of the first node having first threads for executing the application;
• and
• a second node including a second processor and a second memory and having a second runtime environment and a second application monitor that are being executed in the second processor, the second runtime environment of the second node having second threads for executing the application, wherein
• the first application monitor is configured to determine, in response to a system call made by one of the first threads, that executing the system call involves one or more resources present on the second node, and to send the system call and arguments of the system call to the second node for the second node to execute the system call;
• and
• the second application monitor is configured to receive the system call and arguments from the first node and execute the system call using the one or more resources present on the second node, and to send results of the system call to the first node.

A non-transitory computer-readable medium comprising instructions, which when executed in a plurality of nodes, each of which includes a processor and a memory and has an application monitor and a runtime environment that are being executed in the processor thereof, cause the nodes to carry out a method for handling system calls during execution of an application over the plurality of nodes, the method comprising:

• establishing first threads in the runtime environment of a first node among the plurality of nodes and establishing second threads in the runtime environment of a second node among the plurality of nodes;
• determining by the application monitor of the first node, in response to a system call made by one of the first threads, that executing the system call involves one or more resources present on the second node;
• sending by the application monitor of the first node, the system call and arguments of the system call to the second node for the second node to execute the system call;
• receiving by the application monitor of the first node, results of the system call from the second node;
• and
• returning by the application monitor of the first node, the results of the system call to the first thread that made the system call.
