CTAS Processes and Interconnections

This diagram shows all of the CTAS processes and their interconnections.

A two-way connection is shown between the following pairs of processes:
    1. HDAR and ISM
    2. ADAR and ISM
    3. ISM and CM
    4. TGUI and CM
    5. PGUI and CM
    6. DP and CM
    7. RA and CM
    8. PFS and CM
    9. PFS_C and CM

In addition, WDAD writes to a disk file.  WDPD reads from this same disk
file and writes to a different disk file.  CM reads from the disk file
written to by WDPD.

The diagram also depicts a two-way shared memory connection between
the following pairs of processes:
    1. RA and TS
    2. PFS and TS
    3. PFS_C and TS

The diagram shows that the system may be run with multiple RA/TS combinations.

The DP is used for TMA and EDA only.

The PFS/TS combination is used for FAST only.

The PFS_C/TS combination is used for Direct-To/EDA only.
