Abstract

In alternate embodiments, the invention is a message-passing process for routing communications between a transmitting parallel process and a receiving parallel process executing in an application server environment, or a machine or computer-readable memory having the message-passing process programmed therein, the message-passing process comprising: linking a context key to an addressable computing resource in the application server environment; linking the receiving parallel process to the context key; receiving a communication from the transmitting parallel process, wherein the communication transmits the context key; and routing the communication to the addressable computing resource linked to the context key.

Claims

1. A message-passing process for routing communications between a transmitting parallel process and a receiving parallel process executing in an application server environment, the message-passing process comprising:

linking a context key to an addressable computing resource in the application server environment;

linking the receiving parallel process to the context key;

receiving a communication from the transmitting parallel process, wherein the communication transmits the context key; and

routing the communication to the addressable computing resource linked to the context key.

2. The message-passing process of claim 1 wherein the addressable computing resource is a logical partition in a memory accessible to the transmitting parallel process and the receiving parallel process.

3. The message-passing process of claim 1 wherein the addressable computing resource is a cache associated with the receiving parallel process.

4. The message-passing process of claim 1 wherein the addressable computing resource is a partition facility having a routing table that links the context key to a logical partition in the application server environment, and the message-passing process further comprises routing the communication from the partition facility to the logical partition.

5. The message-passing process of claim 1 wherein:

the receiving parallel process is a member of a group;

the context key comprises a member key and a group key;

the receiving parallel process is linked to the member key; and

the group is linked to the group key.

6. The message-passing process of claim 5 wherein the addressable computing resource is a logical partition in a memory accessible to the transmitting parallel process and the receiving parallel process.

7. The message-passing process of claim 5 wherein the addressable computing resource is a partition facility having a routing table that links the context key to a logical partition in the application server environment, and the message-passing process further comprises routing the communication from the partition facility to the logical partition.

8. A parallel processing machine comprising:

a processor;

a memory coupled to the processor;

an application serving environment in the memory operable to cause the processor to respond to a request from a client application; and

a context key manager program in the memory operable to cause the processor to perform a method, the method comprising

allocating resources from the processor, the memory, and the application serving environment for a first parallel process and a second parallel process;

linking a context key to an addressable computing resource in the application serving environment;

linking the second parallel process to the context key;

receiving a communication from the first parallel process, wherein the communication transmits the context key; and

routing the communication to the addressable computing resource linked to the context key.

9. The machine of claim 8 wherein the step of allocating resources comprises negotiating with the application serving environment for resources.

10. The machine of claim 8 wherein the addressable computing resource is a logical partition in the memory accessible to the first parallel process and the second parallel process.

11. The machine of claim 8 wherein the addressable computing resource is a cache associated with the second parallel process.

12. The machine of claim 8 wherein the addressable computing resource is a partition facility having a routing table that links the context key to a logical partition in the application server environment, and the context key manager program further causes the processor to route the communication from the partition facility to the logical partition.

13. The machine of claim 8 wherein:

the second parallel process is a member of a group;

the context key comprises a member key and a group key;

the second parallel process is linked to the member key; and

the group is linked to the group key.

14. A computer-readable memory for causing a computer to perform a message-passing process for routing communications between a transmitting parallel process and a receiving parallel process executing in an application server environment, the message-passing process comprising:

linking a context key to an addressable computing resource in the application server environment;

linking the receiving parallel process to the context key;

receiving a communication from the transmitting parallel process, wherein the communication transmits the context key; and

routing the communication to the addressable computing resource linked to the context key.

15. The computer-readable memory of claim 14 wherein the addressable computing resource is a logical partition in a memory accessible to the transmitting parallel process and the receiving parallel process.

16. The computer-readable memory of claim 14 wherein the addressable computing resource is a cache associated with the receiving parallel process.

17. The computer-readable memory of claim 14 wherein the addressable computing resource is a partition facility having a routing table that links the context key to a logical partition in the application server environment, and the message-passing process further comprises routing the communication from the partition facility to the logical partition.

18. The computer-readable memory of claim 14 wherein:

the receiving parallel process is a member of a group;

the context key comprises a member key and a group key;

the receiving parallel process is linked to the member key; and

the group is linked to the group key.

19. The computer-readable memory of claim 18 wherein the addressable computing resource is a logical partition in a memory accessible to the transmitting parallel process and the receiving parallel process.

20. The computer-readable memory of claim 18 wherein the addressable computing resource is a partition facility having a routing table that links the context key to a logical partition in the application server environment, and the message-passing process further comprises routing the communication from the partition facility to the logical partition.
