  3. Epics Base Release 3.14 Status • Not Supported • HPUX • Versions before 11 do not properly support pthreads • Support will require version 11 • BESSY (Ralph Lange) is working on the port. Ready soon. • Main Porting Problem is multithreading • Good support for pthreads OR • Threads support for implementing epicsThread, epicsMutex, and epicsEvent • Multithreading now required • iocCore is intrinsically multithreaded • CA is also multithreaded but transparent to existing applications.

  4. Epics Base Release 3.14 Status • Supporting many platforms will be a challenge • Each platform has many versions • Many versions of G++ • C++ is particular challenge • Most implementations still don’t fully support standard • Standard C++ library implementations still immature. • Status • First beta release is now available. Ready for test stands, commissioning, etc. Operational systems should still wait. • I have tested vxWorks Test stand with many VME I/O modules • Encourage users to try Win32, Solaris, Linux. • Killer Applications: Sequencer and LAN Gpib

  5. Epics Base Release 3.14 Status • Sequencer • Eric Norum & Marty Kraimer started with latest SLAC version • Has been tested on all supported alpha2 platforms • SLAC has taken back responsibility (Michael Laznovsky) • GPIB: HP2050 LAN Gpib • Eric Norum & Marty Kraimer started with latest BESSY release. • Has been tested on all but winNT. • Support for NI1014 only on vxWorks • Bitbus and bitbus gpib supported on vxWorks • BESSY is still responsible for GPIB. • With new EPICS license APS can still distribute if a Grant of License is signed by BESSY.

  6. Epics Base Release 3.14 Status • Additional Features for 3.14 • Large Arrays – available in beta1 • St.cmd command: rsrvConfig(bufsize,maxbufs) • Transparent to existing clients but must be relinked • Purpose is ease of use not performance • In next release PCAS will also support large arrays. • Multipriority CA servers – available in beta1 • Client must request, i.e. not transparent to existing clients. • Provides incremential improvement for performance degradatation • No other new features for 3.14 • Testing • Some tests are still failing.
