Dear SP Users, NERSC is considering buying license for the NAG SMP library for the IBM SP (seaborg.nersc.gov). This library is available for evaluation till end of March 2002. Please test it and send your feedback/comments to Harsh Anand (hanand_at_lbl_dot_gov). The NAG SMP Library is a library of Fortran 77 routines optimised for use on Symmetric Multi-processor (SMP) machines which are multi-processor platforms with a (virtual or real) shared memory (such as a single node of the SP). It contains all the routines contained in the NAG Fortran Library. The subroutine interfaces of the SMP version are identical to those of the NAG Fortran library; this makes porting from NAG Fortran library to NAG SMP library trivial -- just recompile and relink your code to the SMP Library to take advantage of the capabilities of the architecture IBM SP Power3. Note: NAG_SMP 64-bit library is also available fo evaluation. See the announcement: http://hpcf.nersc.gov/hypermail/sp-announcements/0077.html To use the NAG SMP 32-bit library: 1. First load the module "nag_smp32" %module load nag_smp32 2. Then compile and link with the library, e.g. xlf_r -q32 -qsmp=omp -qnosave -o driver.exe driver.f $NAG_SMP32 where driver.f is your application program. 3. Set the environment variable OMP_NUM_THREADS to the number of available processors. E.g. for C-shell: setenv OMP_NUM_THREADS 16 4. Then execute the program in the "normal" way: ./driver.exe To run example program, (say) c06eaf, do the following: %nagsmpexample c06eaf It will copy the example program and its data into the files c06eafe.f and c06eafe.d in the current directory and process them to produce the example program results.
