Invalid register operand when updating

(let $c := string(../@code) return if ($c castable as xs:double) then number($c) else 0), '0.00') More specifically by "an expression such as an arithmetic expression" I mean an expression that has no explicit streaming support but uses the fallback mechanisms; this generally means an expression whose operands are atomized and which does not accept multi-item sequences as its operands.

Value comparisons probably fall into this category; general comparisons do not.

I write a multi-block single-thread version of an optimization algorithm to optimize the parameters of a hydrological model. However, when I revise it into a multi-block multi-thread version, it can run, but with wrong answer.

In the multi-thread version, for each evolution step, the best solution (bestf) found by the algorithm seems can not be improved sufficiently.

A test case sx-arithmetic-007 has been created in the XSLT 3.0 test suite.

The internal detail: class Streaming Adjunct contains the fallback code for expressions that do not have custom streaming support.

Because in the multi-thread version, there needs many syncthreads() calls and usage of the shared memory, I'm not sure whether I use the synchronization and the shared memory properly.

Section 5.3 discusses the bit-addressability of RAM, registers, and I/O ports.

In Section 5.4 we show how to access the extra 128 bytes of RAM in the 8052.

The GNU C compiler for ARM RISC processors offers, to embed assembly language code into C programs.

This cool feature may be used for manually optimizing time critical parts of the software or to use specific processor instruction, which are not available in the C language.
