- Release 1.4.1.0 focuses on improvements in performance and
- reliability. Performance has been enhanced for many of the
- Level-3 BLAS. For the matrix-matrix multiplication routines
- (*GEMM), performance improvements of up to 3x can be seen
- for large matrices in the NT and TT cases.
-
- The following is a list of improved Level-3 BLAS.
-
-
- SGEMM DGEMM CGEMM ZGEMM
- STRMM DTRMM CTRMM ZTRMM
- STRSM DTRSM CTRSM ZTRSM
- CHERK ZHERK
- SSYMM DSYMM CSYMM ZSYMM
- CHEMM ZHEMM
- SSYRK DSYRK
- CHERK ZHERK
- SSYR2K DSYR2K CSYR2K ZSYR2K
- CHER2K ZHER2K

-
- Many of the LAPACK routines will derive immediate benefit
- from this, since they are often based on Level-3 BLAS calls.
-
- A new recursive parallel algorithm was added to the Cholesky
- factorization routnes. In addition, a new algorithm for the
- QR factorization routines was incorporated that will improve
- parallel performance dramatically.
-
- Along with these performance enhancements, SCSL 1.4.1.0
- includes the following improvements and fixes:
-
- +o Consistent performance for large 1D FFTs.
-
- +o Performance regressions were fixed in the
- convolution/correlation routines.
-
- +o Stability of the iterative solvers was improved.
-
- +o Documentation was improved.
-
- SCSL 1.4.1.0 was compiled with MIPSpro 7.3.1.3m, therefore a
- MipsPro 7.3 runtime environment is required to use SCSL 1.4.
- The following table describes what should be installed on a
- machine to get MIPSpro 7.3.1.3m runtime environment
- installed, so an application developed with MIPSpro 7.3 that
- uses SCSL 1.4.1.0 will run on the targeted machine.

- _I_R_I_X _6._5 _t_h_r_u _6._5._9 patch 3911 - compiler_eoe
- (except libmp)

- patch 3742 - C++ eoe (includes
- libcio.so)

- patch 3965 - compiler_eoe

-
- These patches will also install on IRIX 6.4. Developers
- using IRIX 6.4 thru 6.5.9 should install IRIX Development
- Foundation (IDF) 1.2 or IRIX Development Libraries (IDL).
- Doing this will make all IRIX releases have compatible
- runtime environments.
-
- On IRIX 6.5, installing 7.3.1.3 compilers on top of these
- patches will replace the patches with identical items from
- 7.3.1.3m overlays, so such an installation is fine.
-
- SCSL 1.4.1.0 is shipped as part of IRIX and is available on
- the Applications CD.
