Qemu debugging an assembly kernel -


i writing os in assembly (the bootloader , kernel) , debugging using qemu.
want set debug breakpoints pause executions , execute 1 instruction @ time (single step).also want read , set registers , memory contents @ runtime. read way use gdb. problem haven't used gdb before , after searched realize gdb uses labels puted c compiler (gcc) in object file,doesn't it? said writing in assembly (using nasm) , have pure raw binary how that? exist way? maybe can create own gdb server or that?

i realize gdb uses labels puted c compiler (gcc) in object file

gdb when labels available. when not, gdb display raw addresses.

nothing stops setting breakpoints on raw addresses when other "labels" available.

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...
