"Absoft is pleased to offer Etnus' TotalView debugger, the premier
advanced debugging solution for mission critical code, as part of our
HPC SDK Enhanced Editions for Linux on POWER(TM). TotalView is
universally recognized as the most advanced debugging solution
available for MPI-based systems," said Wood Lotz , CEO of Absoft.
Offering a well rounded set of products, Absoft also sells its own
highly reliable and portable 64-bit Fortran 95 compiler for Linux On
POWER(TM), with a 64-bit Fortran compiler for OS X forthcoming very
soon. They offer significant productivity gains in
application development , helping to eliminate the frustration, delays,
and headaches inherent in analyzing multi-process , multi-thread, and
network-distributed applications containing many lines of code or
advanced programming techniques such as MPI, threads, and OpenMP.
