Suppose w is a word. Let us take w='receive', as used by you. My objective is to extract two words before and after 'receive'. So what I want is this:
But the above assumption is just for simplicity. However, ideally it should not search across line boundaries. Therefore, you have a good point here. The ideal output for 'receive' should be:

The size of the data is typically of the order of hundreds of megabytes, and there are typically a few tens of main shared memory segments each of size... (2 Replies)

We just set up a system to use large pages. I want to know if there is a command to see how much of the memory is being used for large pages. For example if we have a system with 8GB of RAm assigned and it has been set to use 4GB for large pages is there a command to show that 4GB of the *GB is... (1 Reply)

All,
I have a problem with grep/fgrep/egrep. Basically I am building a 200 times 200 correlation matrix. The entries of this matrix need to be retrieved from another very large matrix (~100G). I tried to use the grep/fgrep/egrep to locate each entry and put them into one file. It looks very... (1 Reply)

pvm_setrbuf
SETRBUF(3PVM) PVM Version 3.4 SETRBUF(3PVM)NAME
pvm_setrbuf - Switches the active receive buffer and saves the previous buffer.
SYNOPSIS
C int oldbuf = pvm_setrbuf( int bufid )
Fortran call pvmfsetrbuf( bufid, oldbuf )
PARAMETERS
bufid Integer specifying the message buffer identifier for the new active receive buffer.
oldbuf Integer returning the message buffer identifier for the previous active receive buffer.
DESCRIPTION
The routine pvm_setrbuf switches the active receive buffer to bufid and saves the previous active receive buffer oldbuf. If bufid is set
to 0 then the present active receive buffer is saved and no active receive buffer exists.
A successful receive automatically creates a new active receive buffer. If a previous receive has not been unpacked and needs to be saved
for later, then the previous bufid can be saved and reset later to the active buffer for unpacking.
The routine is required when managing multiple message buffers. For example switching back and forth between two buffers. One buffer
could be used to send information to a graphical interface while a second buffer could be used send data to other tasks in the application.
EXAMPLES
C:
rbuf1 = pvm_setrbuf( rbuf2 );
Fortran:
CALL PVMFSETRBUF( NEWBUF, OLDBUF )
ERRORS
These error conditions can be returned by pvm_setrbuf
PvmBadParam
giving an invalid bufid.
PvmNoSuchBuf
switching to a non-existent message buffer.
