I mean, can we launch Kernel from Mathematica Frontend with a timeout period, may be for 10 seconds so that it gets killed/stopped after 10 seconds?

Amongst these we find TimeConstrained, which can be used as follows. In[1]:= TimeConstrained[Integrate[Sin[x^5 + x^3], x], .0001, "Out of time"] Out[1]= Out of time To have this happen automatically for all inputs we can use In[2]:= $Pre = Function[x, TimeConstrained[x, .0001, "Out of time"], HoldAll]; Example: In[3]:= Integrate[Sin[x^5 + x^4], x] Out[3]= Out of time We can cancel $Pre In[4]:= $Pre =. -- Allan --------------- Allan Hayes hay at haystack.demon.co.uk Voice: +44 (0)116 241 8747 Fax: +44 (0)870 164 0565
