Environment Variable Description

(Optional) KML_BLAS_TYPE
KML_BLAS has three versions: nolocking, locking, and multi. By default, the multi version is used when the KML_RT runtime dynamic library is linked. To specify the KML_BLAS version, use the environment variable KML_BLAS_TYPE. For example, to use the nolocking version of KML_BLAS, add the following environment variable:
```
export KML_BLAS_TYPE=nolocking
```
(Optional) KML_SPBLAS_TYPE
KML_SPBLAS has two versions: single and multi. By default, the single version is used when the KML_RT runtime dynamic library is linked. To specify the KML_SPBLAS version, use the environment variable KML_SPBLAS_TYPE. For example, to use the multi version of KML_SPBLAS, add the following environment variable:
```
export KML_SPBLAS_TYPE=multi
```
(Optional) KML_FFT_TYPE
KML_FFT has two versions: regular and mpi. By default, the regular version is used when the KML_RT runtime dynamic library is linked. To specify the KML_FFT version, use the environment variable KML_FFT_TYPE. For example, to use the mpi version of KML_FFT, add the following environment variable:
```
export KML_FFT_TYPE=mpi
```
(Optional) KML_IPL_TYPE
KML_IPL has two versions: non-omp and omp. By default, the non-omp version is used when the KML_RT runtime dynamic library is linked. To specify the KML_IPL version, use the environment variable KML_IPL_TYPE. For example, to use the omp version of KML_IPL, add the following environment variable:
```
export KML_IPL_TYPE=omp
```
