For asynchronous sharing, shared memory is what I would think of.
For synchronous processes you would have to use combination of shared memory and semaphores. I believe you would need it synchronous if you are reading and writing from and to the pages.

pmsignal
PMSIGNAL(1) General Commands Manual PMSIGNAL(1)
NAME
pmsignal - send a signal to one or more processes
SYNOPSIS
$PCP_BINADM_DIR/pmsignal [-a|-l] [-n] [-s signal] [PID ...|name ...]
DESCRIPTION
pmsignal provides a cross-platform event signalling mechanism for use with tools from the Performance Co-Pilot toolkit. It can be used to
send a named signal (only HUP, USR1, TERM, and KILL are accepted). to one or more processes. The processes are specified using PID or the
binary name (with -a option).
If a signal is not specified, then the TERM signal will be sent.
On Linux and UNIX platforms, pmsignal is a simple wrapper around the kill(1) command. On Windows, the is no direct equivalent to this
mechanism, and so an alternate mechanism has been implemented - this is only honoured by PCP tools, however, not all Windows utilities.
PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the
file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura-
tion file, as described in pcp.conf(5).
SEE ALSO
kill(1), killall(1), pcp.conf(5) and pcp.env(5).
