Detailed Description

BspProxyStubPool - Create and manage BspProxy's stubs.

A BspProxy is a CORBA object that represents each BSP task. A BspProxyStub is dynamically created in this class when requested. All stubs exists only as entities in a LUA state. They are maintained together to save memory, so that we need to load only one copy of the ORB and IDL.

Member Function Documentation

void BspProxyStubPool::bspGetReply (  const string &  proxyId, const BspGetReply &  response )

Reply a remote read made by another BSP task. Parameters: proxyId  - Id of the remote object response  - Contains information regarding the reply

void BspProxyStubPool::bspGetRequest (  const string &  proxyId, const BspGetRequest &  request )

Requests a remote read to another BSP task. Parameters: proxyId  - Id of the remote object request  - Contains information regarding the request

void BspProxyStubPool::bspPut (  string  proxyId, BspPut &  bspPut )

Performs a bsp_put on a remote task. Parameters: proxyId  - Id of the remote object bspPut  - The BspPut details

void BspProxyStubPool::bspSynch (  string  proxyId, int  pid )

Signals to Process zero that the local task reached the synchronization barrier point. Parameters: proxyId  - Id of the remote object pid  - The PID of the local BSP task

void BspProxyStubPool::bspSynchDone (  string  proxyId, int  pid )

Called by Process Zero only. Signals to remote tasks that barrier sinchronization is done. Parameters: proxyId  - Id of the remote object pid  - The PID of the remote BSP task

string BspProxyStubPool::createNewProxy (  const string &  ior  )

Creates a new proxy in the pool Parameters: ior  - IOR of the remote BspProxy object Returns: a string identifier for this proxy that should be used on following remote method invocations

void BspProxyStubPool::registerRemoteIor (  string  proxyId, int  pid, string  ior )

Calls the method registerRemoteIor on a remote object This method is used at initialization time, so that all tasks know the IOR of each other and can communicate on following steps. Parameters: proxyId  - Id of the remote object (The one received when createNewProxy was called) pid  - BSP PID of one of the BSP tasks ior  - IOR that allows one to reach a BSP Proxy

void BspProxyStubPool::takeYourPid (  string  proxyId, int  pid )

Gives a PID to a given BSP task. This method is called ONLY by process zero at each of the BSP proxies in order to set the BSP PID of each of the tasks. This is called ONLY at initialization time Parameters: proxyId  - Id of the remote object pid  - The new BSP PID of a given task
