Algorithmic Differences between LAPACK and ScaLAPACK

 

The following ScaLAPACK routines use different algorithms from their LAPACK counterparts. Refer to the relevant LAPACK working notes or the leading comments of the source code for details.

• PxDBSV, PxDBTRF, PxDBTRS: No LAPACK equivalent; refer to [32].
• PxGBSV, PxGBTRF, PxGBTRS: Refer to [32].
• PxLAHQR: Refer to [79].
• PxPBSV, PxPBTRF, PxPBTRS: Refer to [32].
• PxPTSV, PxPTTRF, PxPTTRS: Refer to [32].
• PxSYEV
• PxSYEVX/PxHEEVX: Refer to [40].
• PxSYGVX/PxHEGVX.
