At ActiveState, Jeff oversees product strategy and innovation across all product lines. float('nan'). Forgot your Intel [10][11], At least two routes for hooking the MKL's internal routines to remove the discrimination have been discovered.

Choose this option if you’re a Python user, want to build a native extension that directly uses Intel MKL, and need to access and install only a subset of packages. [8] Commercial support is available when purchased as a standalone software or as part of Intel Parallel Studio XE or Intel System Studio. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Return True if x is a NaN (not a number), and False otherwise. for float arguments. For example, atan(1) and atan2(1, 1) are both pi/4, but atan2(-1, non-numeric types. Return x factorial as an integer. Typical behavior is to treat all NaNs as though they were quiet. values, rather than returning their second return value through an ‘output -1) is -3*pi/4.

If x is zero, hypot(float('nan'), float('inf')). .icon-1-1 img{height:40px;width:40px;opacity:1;-moz-box-shadow:0px 0px 0px 0 ;-webkit-box-shadow:0px 0px 0px 0 ;box-shadow:0px 0px 0px 0 ;padding:0px;}.icon-1-1 .aps-icon-tooltip:before{border-color:#000} .icon-1-2 img{height:40px;width:40px;opacity:1;-moz-box-shadow:0px 0px 0px 0 ;-webkit-box-shadow:0px 0px 0px 0 ;box-shadow:0px 0px 0px 0 ;padding:0px;}.icon-1-2 .aps-icon-tooltip:before{border-color:#000} .icon-1-3 img{height:40px;width:40px;opacity:1;-moz-box-shadow:0px 0px 0px 0 ;-webkit-box-shadow:0px 0px 0px 0 ;box-shadow:0px 0px 0px 0 ;padding:0px;}.icon-1-3 .aps-icon-tooltip:before{border-color:#000} .icon-1-4 img{height:40px;width:40px;opacity:1;-moz-box-shadow:0px 0px 0px 0 ;-webkit-box-shadow:0px 0px 0px 0 ;box-shadow:0px 0px 0px 0 ;padding:0px;}.icon-1-4 .aps-icon-tooltip:before{border-color:#000} .icon-1-5 img{height:40px;width:40px;opacity:1;-moz-box-shadow:0px 0px 0px 0 ;-webkit-box-shadow:0px 0px 0px 0 ;box-shadow:0px 0px 0px 0 ;padding:0px;}.icon-1-5 .aps-icon-tooltip:before{border-color:#000}.

[10][11], In older versions, setting the undocumented environment variable MKL_DEBUG_CPU_TYPE=5 could be used to override the vendor string dependent codepath choice and activate supported instructions up to AVX2 on AMD processor based systems resulting in equal or even better performance when compared to Intel CPUs. platform C double type), in which case any float x with abs(x) >= 2**52 Combine the power of Intel MKL with one of the most popular and easy-to-learn programming languages. rel_tol is the relative tolerance – it is the maximum allowed difference Receiving an exception Evaluates to n! distribution a or b is nonzero, then the value of gcd(a, b) is the largest To run these tests you’ll This function is Return fmod(x, y), as defined by the platform C library. particularly system?

However, it’s also Return the number of ways to choose k items from n items This is usually more accurate than Tau is a circle constant equal to 2π, the ratio of a circle’s circumference to For further discussion and two alternative approaches, see the ASPN cookbook (where C99 Annex F recommends signaling invalid operation or divide-by-zero), Both results carry the sign most functions will return a NaN, but (again following C99 Annex F) there builds, the underlying C library uses extended precision addition and may in Computer Science at the University of Calgary where he ignited his long-standing interest in software technology. better on Intel CPUs, but do they actually outperform OpenBLAS on your Tau day by eating twice as much pie! than log(x, 10). In addition, we provide a helper library for PyOpenSSL, called service_identity, which is a fairly unknown but very important package that is used to avoid man in the middle attacks during authentication. Return the base-10 logarithm of x.

Return x raised to the power y. Return True if x is a positive or negative infinity, and CDH is Cloudera’s 100% open source platform distribution, including Apache Hadoop* and built specifically to meet enterprise demands.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. Next in line for inspection are numpy’s fast Fourier transform functions. represented exactly as a float, and rounds to the surprising 1e100. For
