Apparatus, method and system for aggregrating computing resources
A system for executing applications designed to run on a single SMP computer on an easily scalable network of computers, while providing each application with computing resources, including processing power, memory and others that exceed the resources available on any single computer. A server agent program, a grid switch apparatus and a grid controller apparatus are included. Methods for creating processes and resources, and for accessing resources transparently across multiple servers are also provided.
1. A method for accessing resources in a distributed computing system, the system comprising a plurality of servers, each server having a plurality of resources, each server having a plurality of threads, each server of said plurality of servers connected through a network, and each server being operable to detect attempts by a thread to access a resource residing on a different server, the method comprising:
automatically intercepting a resource request by the thread; and
alternatively executing one of the following procedures in a selective manner responsive to the intercepted resource request for effect the access:
a. responsive to a first thread attempting to access a first resource, said first thread running on a first server, said first resource located on a second server, hopping said first thread to said second server in order to effect the access;
b. responsive to said first thread attempting to access said first resource, reassigning and moving said first resource to said first server in order to effect the access; and
c. responsive to said first thread attempting to access said first resource, caching said first resource on said first server in order to effect the access.
2. The method as recited in claim 1 further comprising establishing in each of said servers having the threads including an agent operable to automatically intercept all resource requests of the threads therein.
3. The method as recited in claim 1 further comprising establishing in each of said servers having the threads including an agent operable to automatically intercept selected resource requests of the threads therein in response to at least one first condition or event.
4. The method as recited in claim 3 wherein the at least one first condition or event relates to detection of an unsuccessful memory access request.
5. The method of claim 3 wherein the at least one first condition or event relates to detection of a resource-not-found error.
6. The method of claim 3 wherein the at least one first condition or event relates to detection of a resource access failure.
7. The method of claim 3 wherein the at least one first condition or event relates to detection of a resource-not-found-on-thread's-server error.
8. The method of claim 3 wherein the first request relates to a memory access request; and wherein automatic interception of the thread occurs in response to detection of an error relating to the memory access request.
9. A system for accessing resources in a distributed computing system, the system comprising:
a plurality of servers, each server having a plurality of resources, each server having a plurality of threads, each server of said plurality of servers connected through a network, and each server being operable to detect attempts by a thread to access a resource residing on a different server;
the system being operable to:
automatically intercept a resource request by the thread; and
alternatively execute one of the following procedures in a selective manner responsive to the intercepted resource request for effecting the access:
a. responsive to a first thread attempting to access a first resource, said first thread running on a first server, said first resource located on a second server, hopping said first thread to said second server in order to effect the access;
b. responsive to said first thread attempting to access said first resource, reassigning and moving the first resource to said first server in order to effect the access; and
c. responsive to said first thread attempting to access said first resource, caching said first resource on said first server in order to effect the access.
10. The system as recited in claim 9 wherein each of said servers having the threads includes an agent operable to automatically intercept selected resource requests of the threads therein in response to at least one first condition or event.
11. A system for accessing resources in a distributed computing system, the system comprising:
a plurality of servers, each server having a plurality of resources, each server having a plurality of threads, each server of said plurality of servers connected through a network, and each server being operable to detect attempts by a thread to access a resource residing on a different server;
means for automatically intercepting a resource request by the thread; and
means for alternatively executing one of the following procedures in a selective manner responsive to the intercepted resource request for effecting the access:
a. responsive to a first thread attempting to access a first resource, said first thread running on a first server, said first resource located on a second server, hopping said first thread to said second server in order to effect the access;
b. responsive to said first thread attempting to access said first resource, reassigning and moving the first resource to said first server in order to effect the access; and
c. responsive to said first thread attempting to access said first resource, caching said first resource on said first server in order to effect the access.
12. The system as recited in claim 11 wherein each of said servers having the threads includes an agent operable to automatically intercept selected resource requests of the threads therein in response to at least one first condition or event.
