Bernese - Tutorial: Configuration of PCFCTL.CPU File
Configuration of PCFCTL.CPU File
The Bernese Processing Engine (BPE) is able to utilize multiple computers
for processing GPS data. The BPE uses a file called the PCFCTL.CPU
file to select which machines are available for processing.
The PCFCTL.CPU file is discussed in section 21.2.4
in the Bernese V4.0 documentation. Refer to this section for further
details.
The PCFCTL.CPU is located in the $U/WORK directory.
The file should look something like this:
yochi[braunj]:V40-$ cd $U/WORK
yochi[braunj]:V40-$ ls PCFCTL.CPU
PCFCTL.CPU
yochi[braunj]:V40-$ vi PCFCTL.CPU
# Process control CPU informaton
CPU TRUE_NAME SPEED NCPU SF IDLE MAXJ JOBS

CPU1 yochi FAST 2 100 100 4 0
CPU2 erde FAST 1 100 100 2 0
Edit this file, adding the names of the machines that are to be used
for data processing. Use the format shown in the example, and do not
edit the header lines. They are used for proper formating. Here
are some comments that may be useful.
- The CPU name is an internal name used by the BPE. It
can be up to 8 characters in length. It is suggested that you
use the naming convention in the example (i.e. CPU1,
CPU2, CPU3 ...).
- The TRUE_NAME is the host name of the machine. It
must be a true host name, and can be up to 30 characters in length.
- The MAXJ is the maximum number of BPE jobs that should
be running on that particular host. This value should probably
not be more that twice the number of processors on the computer.
- The SPEED, NCPU, SF, and
IDLE are not currently used. They are place holders for
future changes to the BPE.
