16 bit - Can I make gcc treat an 'int' as 16 bits on an x86 platform? -


i developing code proprietary architecture. development environment consists of half-ported gcc 4.3 available windows, , primitive ide. because of this, develop on linux primary environment, using newer gcc nicer warnings.

however, maximize number of relevant warnings gcc work 16-bit ints while still being able run on native x86 platform. can think of 3 ways of doing this, in order of preference:

  1. a flag makes 'int' 16-bit integer. far have not found any. -m16 not seem it, maybe 1 of architecture options it.

  2. a flag turns on warnings things might problem if int 16 bits, if int 32 or 64 bits in actual code. can happen due integer promotions , hard see @ glance. compiler warnings helpful here.

  3. a compiler flag when building gcc. build custom x86 version of gcc, treats 'int' 16 bits. there such option?

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
