Process | getSender () |
A task is either something to compute somewhere, or something to exchange between two hosts (or both). It is defined by a computing amount and a message size.
simgrid::msg::Task::Task | ( | ) | [inline] |
Default constructor (all fields to 0 or null)
simgrid::msg::Task::Task | ( | String | name, | |
double | computeDuration, | |||
double | messageSize | |||
) | [inline] |
Construct an new task with the specified processing amount and amount of data needed.
name | Task's name | |
computeDuration | A value of the processing amount (in flop) needed to process the task. If 0, then it cannot be executed with the execute() method. This value has to be >= 0. | |
messageSize | A value of amount of data (in bytes) needed to transfert this task. If 0, then it cannot be transfered with the get() and put() methods. This value has to be >= 0. |
simgrid::msg::Task::Task | ( | String | name, | |
Host[] | hosts, | |||
double[] | computeDurations, | |||
double[] | messageSizes | |||
) | [inline] |
Construct an new parallel task with the specified processing amount and amount for each host implied.
name | The name of the parallel task. | |
hosts | The list of hosts implied by the parallel task. | |
computeDurations | The amount of operations to be performed by each host of hosts. | |
messageSizes | A matrix describing the amount of data to exchange between hosts. |
String simgrid::msg::Task::getName | ( | ) | [inline] |
Gets the name of a task
Process simgrid::msg::Task::getSender | ( | ) | [inline, package] |
Gets the sender of the task
Host simgrid::msg::Task::getSource | ( | ) | [inline] |
Gets the source of the task
double simgrid::msg::Task::getComputeDuration | ( | ) | [inline] |
Gets the computing amount of the task
double simgrid::msg::Task::getRemainingDuration | ( | ) | [inline] |
Gets the remaining computation of the task
void simgrid::msg::Task::setPriority | ( | double | priority | ) | [inline] |
This method sets the priority of the computation of the task. The priority doesn't affect the transfert rate. For example a priority of 2 will make the task receive two times more cpu than the other ones.
priority | The new priority of the task. |
void simgrid::msg::Task::execute | ( | ) | throws HostFailureException,TaskCancelledException [inline] |
Executes a task on the location on which the process is running.
HostFailureException,TaskCancelledException |
void simgrid::msg::Task::cancel | ( | ) | [inline] |
Cancels a task.
NativeException | if the cancellation failed. |
void simgrid::msg::Task::finalize | ( | ) | throws NativeException [inline, protected] |
Deletes a task.
NativeException | if the destruction failed. |
void simgrid::msg::Task::send | ( | String | mailbox | ) | throws TransferFailureException, HostFailureException, TimeoutException [inline] |
Sends the task on the mailbox identified by the specified name
void simgrid::msg::Task::send | ( | String | mailbox, | |
double | timeout | |||
) | throws NativeException, TransferFailureException, HostFailureException, TimeoutException [inline] |
Sends the task on the mailbox identified by the specified name (wait at most timeout seconds)
NativeException | if the retrieval fails. | |
TimeoutException | ||
HostFailureException | ||
TransferFailureException |
void simgrid::msg::Task::sendBounded | ( | String | alias, | |
double | maxrate | |||
) | throws TransferFailureException, HostFailureException, TimeoutException [inline] |
Sends the task on the mailbox identified by the specified alias (capping the sending rate to maxrate)
TransferFailureException,HostFailureException,TimeoutException. |
static Task simgrid::msg::Task::receive | ( | String | mailbox | ) | throws TransferFailureException, HostFailureException, TimeoutException [inline, static] |
Retrieves next task from the mailbox identified by the specified name
TransferFailureException,HostFailureException,TimeoutException | if the retrieval fails. |
static Task simgrid::msg::Task::receive | ( | String | mailbox, | |
double | timeout | |||
) | throws TransferFailureException, HostFailureException, TimeoutException [inline, static] |
Retrieves next task on the mailbox identified by the specified name (wait at most timeout seconds)
TransferFailureException,HostFailureException,TimeoutException | if the retrieval fails. |
static Task simgrid::msg::Task::receive | ( | String | mailbox, | |
Host | host | |||
) | throws TransferFailureException, HostFailureException, TimeoutException [inline, static] |
Retrieves next task sent by a given host on the mailbox identified by the specified alias
TransferFailureException,HostFailureException,TimeoutException | if the retrieval fails. |
static Task simgrid::msg::Task::receive | ( | String | mailbox, | |
double | timeout, | |||
Host | host | |||
) | throws TransferFailureException, HostFailureException, TimeoutException [inline, static] |
Retrieves next task sent by a given host on the mailbox identified by the specified alias (wait at most timeout seconds)
TransferFailureException,HostFailureException,TimeoutException | if the retrieval fails. |
static int simgrid::msg::Task::listenFrom | ( | String | mailbox | ) | [inline, static] |
Tests whether there is a pending communication on the mailbox identified by the specified alias, and who sent it
static boolean simgrid::msg::Task::listen | ( | String | mailbox | ) | [inline, static] |
Listen whether there is a waiting task on the mailbox identified by the specified alias
static int simgrid::msg::Task::listenFromHost | ( | String | alias, | |
Host | host | |||
) | [inline, static] |
Counts the number of tasks waiting to be received on the mailbox identified by the specified alia and sended by the specified host.
long simgrid::msg::Task::bind = 0 |
This attribute represents a bind between a java task object and a native task. Even if this attribute is public you must never access to it. It is set automatically during the build of the object.
