Hello, I am posting this on this list hoping someone will direct me. Feel free to forward this to anyone, anywhere. Also, please CC adonev@princeton.edu to any replies. I am a scientific programmer and am developing tools for manual profiling of Fortran programs. There seem to be now several library API's for obtaining hardware performance statistics under Linux x86 in the newer 2.4.x kernels, such as the PAPI profiling API. These provide access to some most useful information such as flops and cache use. I am also interested in profiling memory usage, in particular heap usage. But I have been unable to find any libraries or other tools to instrument a code to obtain some memory usage profiling statistics. getrusage for example does not seem to work. I am sure the linux kernel knows about memory allocations/deallocations/swapping and other such activities of a given process, but I am not sure if the kernel maintains these statistics and if I can somehow access them, other then via access to /proc (I don't even know of an API to do that other than getrusage, which does not seem to work under 2.4 kernels) I am not an OS programmer, but can deal with a reasonable API if there is one, even if low level. Any clues are greatly appreciated. Thanks, Aleksandar P.S. I use Red Hat 7.3 on a Pentium III (and also Athlon) -- __________________________________ Aleksandar Donev Complex Materials Theory Group (http://cherrypit.princeton.edu/) Princeton Materials Institute & Program in Applied and Computational Mathematics @ Princeton University Address: 419 Bowen Hall, 70 Prospect Avenue Princeton University Princeton, NJ 08540-5211 E-mail: adonev@princeton.edu WWW: http://atom.princeton.edu/donev Phone: (609) 258-2775 Fax: (609) 258-6878 __________________________________ _______________________________________________ Redhat-devel-list mailing list Redhat-devel-list@redhat.com https://listman.redhat.com/mailman/listinfo/redhat-devel-list
