Type "show copying" and "show warranty" for details. Quick question: does the error occur even if the environment variable CILK_NWORKERS=1 is set, or is CILK_NWORKERS >=2 required? I went back checking older commits and tested till when it worked and it was 0480867. Floating Point Exception (core Dumped) rmackay9 added this to the AC 3.3.0 milestone Apr 21, 2015 krufab commented Apr 21, 2015 Hi, here you can find an example.
rmackay9 commented Apr 23, 2015 very strange. Floating Point Exception In C In contrast, processors such as SPARC, PA-RISC, Alpha, MIPS and POWER/PowerPC work with native double-precision values throughout.(26) The differences between these implementations lead to changes in rounding and underflow/overflow behavior, because Any chance you can reproduce the error in gdb or some other debugger and generate a stack trace or identify which basic block where the error is being tripped?

I commented out the define RESTORE_X86_FP_STATE at the top of libcilkrts/runtime/config/x86/os-unix-sysdep.c to obtain the following // On x86 processors (but not MIC processors), the if(throttle_out > 1000){ throttle_out = 1000; }else if(throttle_out < 0){ throttle_out = 0; } Here is the ouput when thottle_out is negative (due to a vz positive): I: 1 B: 1.01058 The C99 standard does not define a way to set individual bits in the floating-point mask, for example, to trap on specific flags.
You can also install an exception handler for SIGFPE for custom error handling. http://jayconrod.com/posts/33/trapping-floating-point-exceptions-in-linux That's a use case for gdb: $ gdb ./a.out GNU gdb (GDB) Fedora (7.5.1-37.fc18) Copyright (C) 2012 Free Software Foundation, Inc.

errno is set to ERANGE, and an "overflow" (FE_OVERFLOW) floating-point exception is raised. my review here You signed out in another tab or window. I tried for hours to recreate this exception but was unable to. It seems that 32bit compilers aren't very compatible with this project. Feenableexcept
Type "show copying" and "show warranty" for details. Not the answer you're looking for? Various rounding modes may be provided: round to nearest (the default), round up (toward positive infinity), round down (toward negative infinity), and round toward zero. http://jamisonsoftware.com/floating-point/floating-point-exception-error-in-ns2.php On Friday, it started giving me the problem above with the InertialSensor.
Since version 2.2, glibc supports the functions feenableexcept() and fedisableexcept() to set individual floating-point traps, and fegetexcept() to query the state. #define _GNU_SOURCE /* See feature_test_macros(7) */ #include Copyright © Jay Conrod, 2009-2016 Skip to main content Developer Zone Join today Log in DevelopmentOSAndroid*Chrome*HTML5Windows*Device2-in-1 & Ultrabook™Business ClientEmbedded SystemsIoTServer, Workstation, HPCTechnologyBig DataDual ScreenGame DevIntel® RealSense™ISA ExtensionsMachine LearningModern CodeNetworkingOpen SourceStorageToolsDeveloper TypeEmbedded
On x86 GNU/Linux systems the default mode is extended precision (with the aim of providing increased accuracy).

In practice, there are often minor variations caused by differences in the order of operations (depending on the compiler and optimization level) but these are generally not significant. cov(x,y)=0 but corr(x,y)=1 Is it illegal for regular US citizens to possess or read documents leaked by Wikileaks?
