Utilities for Parallel Computations
ts_tempfile generates a unique temporary
filename that includes the name of the host machine
and/or the caller's process id, so that it is thread
safe.
hostfile generates a temporary filename composed
with the name of the host machine and/or the current
process id.
gVariable generates a function that access a
global static variable, possibly in shared memory (only
for numeric matrix-coercible data in this case). It is
used primarily in parallel computations, to preserve data
accross computations that are performed by the same
process.
ts_eval(mutex = synchronicity::boost.mutex(),
verbose = FALSE)
ts_tempfile(pattern = "file", ..., host = TRUE,
pid = TRUE)
hostfile(pattern = "file", tmpdir = tempdir(),
fileext = "", host = TRUE, pid = TRUE)
gVariable(init, shared = FALSE)mutex |
a mutex or a mutex descriptor. If missing, a new mutex is created via the function boost.mutex from the synchronicity package. |
verbose |
a logical that indicates if messages should be printed when locking and unlocking the mutex. |
... |
extra arguments passed to
|
host |
logical that indicates if the host machine name should be appear in the filename. |
pid |
logical that indicates if the current process id be appear in the filename. |
init |
initial value |
shared |
a logical that indicates if the variable should be stored in shared memory or in a local environment. |
pattern |
a non-empty character vector giving the initial part of the name. |
tmpdir |
a non-empty character vector giving the directory name |
fileext |
a non-empty character vector giving the file extension |
