NAME
ucvm_query
SYNOPSIS
ucvm_query [-h] [-f config] [-m model] [-c coordtype] [-v] [-z zmin,zmax]
DESCRIPTION
The command ucvm_query queries an installed velocity model to retreive its material properties
at a particular latitude and longitude.
Any set of crustal and GTL velocity models may be selected and queried in order of preference.
Points may be queried by (lon,lat,dep) or (lon,lat,elev) and the coordinate conversions for
a particular model are handled transparently.
Common Parameters
-h Displays the help message.
-f Location of the configuration file, config, that tells the program which velocity models are installed.
-m A comma-separated list of models to query.
Less Used Parameters
-c Z-coordinate mode. Geo-depth (default) is "gd",
but queries can also be done by elevation as specified by "ge".
-v Display model version information only.
-z Specifies depth range for gtl/crust interpolation.
EXAMPLE
ucvm_query -f ../conf/ucvm.conf -m cvms
ucvm_query -f /usr/local/opt/ucvm/conf/ucvm.conf -m cvmh -l 33.84007,-117.95683,0.0

NAME
basin_query
SYNOPSIS
basin_query [-h] [-f config-file] [-m model] [-v vs-threshold]
[-z zmin,zmax] [-d max-depth] [-i interval] < file.in
DESCRIPTION
The command basin_query allows you to retrieve the depth at which vs-threshold is first crossed.
By default, vs-threshold is set to be 1000m/s, but that can easily be changed.
Common Paramters
-f Location of the UCVM configuration file. Typically, this is ../conf/ucvm.conf.
-m Model to query. Usually model is either cvms, cvmh, cvmsi, or cencal.
-v Vs threshold to use. By default this is 1000m/s, but other common values include 2500m/s and 3000m/s.
-z Custom depth range for GTL/crust interpolation.
-d Maximum depth, in meters, to search. Default is 15000m.
-i Interval, in meters, go go by when searching for the depth. Default is 20m.
So basin_query will get the Vs value at 0m, 20m, 40m, and so on.
EXAMPLE
basin_query -f ../conf/ucvm.conf -m cvms -v 2500
Input: -118.0 34.0
Output: -118.0000 34.0000 4780.000 4780.000

#UCVM Etree Mesh Programs
NAME
ucvm2etree
SYNOPSIS
ucvm2etree [-h] -f config
DESCRIPTION
The command ucvm2etree builds an e-tree from the specifications in a given configuration file, config.
Note that this is the serial version of the command, meaning that it will only run on a single process. As such, building a
large e-tree can be very slow. For large e-trees, we strongly recommend using ucvm2etree-extract-MPI, ucvm2etree-sort-MPI, and
ucvm2etree-merge-MPI.
-h Displays the help message.

##ucvm2etree-sort-MPI
UCVM(1) BSD General Commands Manual UCVM(1)
NAME
ucvm2etree-sort-MPI
SYNOPSIS
ucvm2etree-sort-MPI [-h] -f config
DESCRIPTION
Notice: This command is intended to be run as a MPI job (e.g. mpirun ./ucvm-sort-MPI). Please do not attempt to
run it as a regular process.
The command ucvm2etree-sort-MPI sorts the extracted components of an e-tree from the ucvm2etree-extract-MPI com-
mand. It does so by reading in the specifications in a given configuration file, config.
Specifically, it sorts the sub-etrees produced by ucvm2etree-extract-MPI so that each file is in local pre-order
(Z-order). Again, the is an embarrassingly parallel operation. Each rank in the job reads in one of the sub-
etrees produced by the previous program, sorts the octants in Z-order, and writes the sorted octants to a new
sub-etree. The sorter must be run on 2^Y cores where Y>0. The worker pool must be large enough to allow each
worker to load all the octants from its assigned file into memory. By default, this octant limit is 20M octants.
If a rank reports that the size of the sub-etree exceeds memory capacity, the 20M buffer size constant may be
increased if memory allows, or alternatively, cvmbycols-extract-MPI may be rerun with a larger job size to reduce
the number of octants per file.
You would typically run this command after ucvm2etree-extract-MPI and before ucvm2etree-merge-MPI.
-h Displays the help message.
-f Uses configuration file, config.

##ucvm2etree-merge-MPI
UCVM(1) BSD General Commands Manual UCVM(1)
NAME
ucvm2etree-merge-MPI
SYNOPSIS
ucvm2etree-merge-MPI [-h] -f config
DESCRIPTION
Notice: This command is intended to be run as a MPI job (e.g. mpirun ./ucvm-merge-MPI). Please do not attempt to
run it as a regular process.
The command ucvm2etree-merge-MPI merges the sorted components of an e-tree from the ucvm2etree-sort-MPI command.
It does so by reading in the specifications in a given configuration file, config.
Specifically, it merges N locally sorted etrees in flat file format into a final, compacted etree. This is essen-
tially a merge sort on the keys from the addresses read from the local files. The cores at the lowest level of
the merge tree each read in octants from two flat files in pre-order, merge sort the two sets of addresses, then
pass the locally sorted list of addresses to a parent node for additional merging. This proceeds until the points
rise to rank 1 which has a completely sorted list of etree addresses. Rank 0 takes this sorted list and performs
a transactional append on the final Etree.
The merger must be run on 2^N cores. The program reads in input files that are in flat file format. In can output
a merged Etree in either Etree format or flat file format. Although, due to space considerations, it strips the
output flat file format to a pre-order list ot octants(16 byte key, 12 byte payload). The missing addr field is
redundant and can be regenerated from the key field.
You would typically run this command after ucvm2etree-extract-MPI and ucvm2etree-merge-MPI.
-h Displays the help message.
-f Uses configuration file, config.

##ucvm2etree-extract-MPI
UCVM(1) BSD General Commands Manual UCVM(1)
NAME
ucvm2etree-extract-MPI
SYNOPSIS
ucvm2etree-extract-MPI [-h] -f config
DESCRIPTION
Notice: This command is intended to be run as a MPI job (e.g. mpirun ./ucvm-extract-MPI). Please do not attempt
to run it as a regular process.
The command ucvm2etree-extract-MPI extracts components of an e-tree from the specifications in a given configura-
tion file, config.
Specifically, it divides the etree region into C columns for extraction. This is an embarrassingly parallel oper-
ation. A dispatcher (rank 0) farms out each column to a worker in a pool of N cores for extraction. Each worker
queries UCVM for the points in its column and writes a flat-file formatted etree. After program execution, there
are N sub-etree files, each locally unsorted. The extractor must be run on 2^Y + 1 cores where Y>0 and (2^Y) < C.
The output flat file format is a list of octants(24 byte addr, 16 byte key, 12 byte payload) in arbitrary Z-
order.
Since the number of points in a column depends on the minimum Vs values within that column, some columns will
have high octant counts and others will have very low octant counts. Having sub-etrees that vary greatly in size
is not optimal for the sorting operations that follow, so ucvm2etree-extract-MPI implements a simple octant bal-
ancing mechanism. When a worker has extracted more than X octants (the default 16M octants), it reports to the
dispatcher that it cannot extract any more columns and terminates. This strategy approximately balances the sub-
etrees so that they may be loaded into memory by ucvm2etree-sort-MPI. In the case of very large extractions where
the dispatcher reports that all workers have reported they are full yet columns remain to be extracted, increase
the job size by a factor of 2 until there is room for all the columns.
You would typically run this command, followed by ucvm2etree-sort-MPI and ucvm2etree-merge-MPI.
-h Displays the help message.
-f Uses configuration file, config.
