# Example libcufile job, using cufile I/O
#
# Required environment variables:
#     GPU_DEV_IDS : refer to option 'gpu_dev_ids'
#     FIO_DIR     : 'directory'. This job uses cuda_io=cufile, so path(s) must
#                   point to GPUDirect Storage filesystem(s)
#

[global]
ioengine=libcufile
directory=${FIO_DIR}
gpu_dev_ids=${GPU_DEV_IDS}
cuda_io=cufile
# 'direct' must be 1 when using cuda_io=cufile
direct=1
# Performance is negatively affected if 'bs' is not a multiple of 4k.
# Refer to GDS cuFile documentation.
bs=1m
size=1m

# cudaMalloc fails if too many processes attach to the GPU, use threads.
