NAME

DESCRIPTION

Applications written in C must be linked with at least the base PVM library, libpvm3.a. Fortran applications must be linked with both libfpvm3.a and libpvm3.a. On some operating systems, PVM programs must be linked with other vendor-provided libraries (containing for example, socket or XDR functions).

Programs that use group functions must also be linked with libgpvm3.a.

ERRORS

PvmAlready

The requested operation requires exclusive access, and another was already in progress.

PvmBadMsg

The received messages has a data format native to another machine, which cannot be decoded by libpvm.

PvmBadParam

A bad parameter was passed to the function.

PvmBadVersion

Two PVM components (pvmd and task, two pvmds or two tasks) have incompatible protocol versions and cannot interoperate. Version mismatch

PvmCantStart

A pvmd could not be started on the local host, or a slave pvmd could not be started on a remote host.

PvmDSysErr

Some internal mechanism in the pvmd failed during the requested operation.

PvmDupEntry

The class server already has an entry matching the insert request. [In Version 3.4: Relaced by PvmExists]

PvmDupGroup

The task has already a member of the group it attempted to join.

PvmDupHost

An attempt was made to add the same host to a virtual machine more than once, or to add a host already a member of another virtual machine owned by the same user.

PvmDenied

Operation is refused due to locking, permissions, etc.

PvmExists

There is already an entry matching the insert request.

PvmHostFail

A foreign host in the virtual machine failed during the requested operation.

PvmMismatch

A parameter does not match a corresponding one.

PvmNoBuf

There is no current message buffer to pack or unpack.

PvmNoData

The end of a message buffer was reached while trying to unpack data.

PvmNoEntry

The class server has no entry matching the lookup request.
[In Version 3.4: Relaced by PvmNotFound]

PvmNoFile

The named executable does not exist.

PvmNoGroup

The named group does not exist.

PvmNoHost

There is no host in the virtual machine with the given name, or the name could not be resolved to an address.

PvmNoInst

The named group has no member with this instance.

PvmNoMem

Malloc failed to get memory for libpvm.

PvmNoParent

This task has no parent task.

PvmNoSuchBuf

There is no message buffer with the given buffer handle.

PvmNoTask

No task exists with the given tid.

PvmNotFound

No entry matching the lookup request was found.

PvmNotImpl

This libpvm function or option is not implemented.

PvmNotInGroup

The named group has no such member task.

PvmNullGroup

A null group name was passed to a function.

PvmOutOfRes

The requested operation could not be completed due to lack of resources.

PvmOverflow

A value is too large to be packed or unpacked.

PvmSysErr

Libpvm could not contact a pvmd on the local host, or the pvmd failed during an operation.
