SYNOPSIS
grib_repack [options] grib2filein grib2fileout
grib -h
for help
DESCRIPTION
repack the data in grib2filein with a different packing scheme.
OPTIONS -h Give help
-pN Desired packing type, where N is:
0 for simple packing
1 for simple matrix packing
2 for complex packing
3 for complex packing with spatial differencing
4 for no packing (ieee)
40 for JPEG2000 packing
41 for PNG packing
61 for simple log pre-processing

INITSEND(3PVM) PVM Version 3.4 INITSEND(3PVM)NAME
pvm_initsend - Clear default send buffer and specify message encoding.
SYNOPSIS
C int bufid = pvm_initsend( int encoding )
Fortran call pvmfinitsend( encoding, bufid )
PARAMETERS
encoding
Integer specifying the next message's encoding scheme.
Options in C are:
Encoding value MEANING
PvmDataDefault 0 XDR
PvmDataRaw 1 no encoding
PvmDataInPlace 2 data left in place
Option names are in Fortran are:
Encoding value MEANING
PVMDEFAULT 0 XDR
PVMRAW 1 no encoding
PVMINPLACE 2 data left in place
bufid Integer returned containing the message buffer identifier. Values less than zero indicate an error.
DESCRIPTION
The routine pvm_initsend clears the send buffer and prepares it for packing a new message. The encoding scheme used for the packing is set
by encoding. XDR encoding is used by default because PVM can not know if the user is going to add a heterogeneous machine before this mes-
sage is sent. If the user knows that the next message will only be sent to a machine that understands the native format, then he can use
PvmDataRaw encoding and save on encoding costs.
PvmDataInPlace encoding specifies that data be left in place during packing. The message buffer only contains the sizes and pointers to
the items to be sent. When pvm_send is called the items are copied directly out of the user's memory. This option decreases the number of
times a message is copied at the expense of requiring the user to not modify the items between the time they are packed and the time they
are sent.
If pvm_initsend is successful, then bufid will contain the message buffer identifier. If some error occurs then bufid will be < 0.
RESTRICTIONS
PvmDataInPlace allows only dense (stride = 1) data in version 3.3. It cannot be used on shared memory (*MP) architectures; a PvmNotImpl
error will occur at send time.
EXAMPLES
C:
bufid = pvm_initsend( PvmDataDefault );
info = pvm_pkint( array, 10, 1 );
msgtag = 3 ;
info = pvm_send( tid, msgtag );
Fortran:
CALL PVMFINITSEND(PVMRAW, BUFID)
CALL PVMFPACK( REAL4, DATA, 100, 1, INFO )
CALL PVMFSEND( TID, 3, INFO )
ERRORS
These error conditions can be returned by pvm_initsend
PvmBadParam
giving an invalid encoding value
PvmNoMem
Malloc has failed. There is not enough memory to create the buffer
