Hi, I modified slighly the Makefile.linuxpgcc in order to get ALL sources compiled with OPT flags ( please find it attached ). Then I recompiled everything from scratch and took benchmarks. I have found that the first time I do ".x benchmarks.C" I get results similar to these from my previous mail, but if I start it once more I get slighly better results ( disk cache maybe ). Please find attached my new benchmarks.C.out ( coming from "third execution" of root ) Best regards, Jacek. # Makefile of ROOT for Linux ( RH5.2 i386 ) with glibc and PGCC # ( PGCC i586/i686 RPMs can be found at http://www.foyer.se/PGCC.html ) PGCC = /opt/pgcc PLATFORM = linux CXX = g++ CC = pgcc CXXFLAGS = -Wall -fPIC -DR__GLIBC -fno-rtti -fno-exceptions CFLAGS = -Wall -fPIC -DR__GLIBC CINTCXXFLAGS = -Wall -fPIC -fno-rtti -fno-exceptions -DG__REGEXP \ -DG__UNIX -DG__SHAREDLIB -DG__OSFDLL -DG__ROOT -DG__REDIRECTIO CINTCFLAGS = -Wall -fPIC -DG__REGEXP -DG__UNIX -DG__SHAREDLIB \ -DG__OSFDLL -DG__ROOT -DG__REDIRECTIO #OPT = -g OPT = -O6 -mpentiumpro -mstack-align-double -funroll-all-loops NOOPT = $(OPT) LD = g++ LDFLAGS = $(OPT) -Wl,-rpath,$(PGCC)/lib:$(ROOTSYS)/lib SOFLAGS = -shared -Wl,-soname, SOEXT = so SYSLIBS = -lm -ldl -rdynamic SYSXLIBS = -L/usr/X11R6/lib -lX11 -lm -ldl -rdynamic XLIBS = $(ROOTSYS)/lib/libXpm.a -L/usr/X11R6/lib -lX11 CILIBS = -lm -ltermcap -lbsd -ldl -rdynamic ##### MACROS and TARGETS ##### include Make-macros ##### DEPENDENCIES ##### include Make-depend [holeczek@p2a02 tutorials]$ root ******************************************* * * * W E L C O M E to R O O T * * * * Version 2.21/07 8 March 1999 * * * * You are welcome to visit our Web site * * http://root.cern.ch * * * ******************************************* CINT/ROOT C/C++ Interpreter version 5.13.90, Feb 18 1999 Type ? for help.
