xx_comm_Rprof: A Rprof Function for SPMD Routines

In pbdMPI: R Interface to MPI for HPC Clusters (Programming with Big Data Project)

A Rprof Function for SPMD Routines

Description

A Rprof function for use with parallel codes executed in the batch SPMD style.

Usage

comm.Rprof(filename = "Rprof.out", append = FALSE, interval = 0.02,
           memory.profiling = FALSE, gc.profiling = FALSE,
           line.profiling = FALSE, numfiles = 100L, bufsize = 10000L,
           all.rank = .pbd_env$SPMD.CT$Rprof.all.rank,
           rank.Rprof = .pbd_env$SPMD.CT$rank.source,
           comm = .pbd_env$SPMD.CT$comm)

Arguments

filename	as in Rprof().
append	as in Rprof().
interval	as in Rprof().
memory.profiling	as in Rprof().
gc.profiling	as in Rprof().
line.profiling	as in Rprof().
numfiles	as in Rprof().
bufsize	as in Rprof().
all.rank	if calling Rprof on all ranks (default = FALSE).
rank.Rprof	rank for calling Rprof if all.rank = FALSE (default = 0).
comm	a communicator number.

Details
