# make IMAGE=hpcimage v1_cilk

# ========= Inside CSAL Image build rules ===========
|
||||
#
|
||||
# 1) first jump into image (make sure you are in the directory where Makefile is):
|
||||
# > docker run -it -v ${PWD}:/usr/src/exercise_1 -w /usr/src/exercise_1/ hpcimage
|
||||
# 2) Clean binaries first **important**
|
||||
# > make clean
|
||||
# 3) for v4 cilk for example:
|
||||
# > make csal_v4_cilk
|
||||
# 4) run executables from `bin/`. Examples:
|
||||
# > ./bin/tcount_ompv3 -i mtx/NACA0015.mtx --timing -r 3 -o /dev/null
|
||||
# > ./bin/tcount_pthv4 -i mtx/com_Youtube.mtx --timing --dynamic --print_count
|
||||
|
||||
|
||||
|
||||
#
|
||||
# ======== Run from container =========
|
||||
#
|
||||
# examples:
|
||||
#
|
||||
# make IMAGE=hpcimage EXEC=knnsearch_v1 run
|
||||
# make IMAGE=hpcimage EXEC=knnsearch_v1 run
