Environment Vaiables

VE_NLCPY_NODELIST

Sets the execution VE node ids.

Example when using VE 0,1,2:

$ export VE_NLCPY_NODELIST=0,1,2

VE_NLCPY_MEMPOOL_SIZE

Default: 1G

Sets the upper limit of memory amount that can be allocated from memory pool. You can specify the suffixes B, b, K, k, M, m, G, or g.

If you don’t specify any suffixes, the value is represented in Kilobytes.

Example that sets pool size 10 gigabytes:

$ export VE_NLCPY_MEMPOOL_SIZE=10G

VE_NLCPY_FAST_MATH

Default: NO

If set to YES or yes, NLCPy uses shared object libnlcpy_ve_kernel_fast_math.so for VE. For details, please see Optimization for Mathematical Functions

VE_NLCPY_ENABLE_NUMPY_WRAP

Default: YES

If set to NO or no, NLCPy raises Exception when replacing NLCPy function and method to NumPy’s one.

VE_OMP_NUM_THREADS

Default: The number of VE cores.

The number of OpenMP parallel threads.

$ export VE_OMP_NUM_THREADS=4

VE_NODE_NUMBER

Default: 0

The node number of VE to be executed. Note that if both VE_NLCPY_NODELIST and VE_NODE_NUMBER are set, VE_NLCPY_NODELIST takes precedence.

$ export VE_NODE_NUMBER=1
