Of Time & Memory

What if I don't know PID? So if you want to know the total amount of memory your program has asked for, use VmPeak; if you want to know how much of your actual RAM it has ever used at a given time, use VmHWM. Probably it always returns 0 because ls isn't doing much.

Try a more CPU intensive command. From the man page: Most information shown by time is derived from the wait3 2 system call. The numbers are only as good as those returned by wait3 2. On systems that do not have a wait3 2 call that returns status information, the times 2 system call is used instead. However, it provides much less information than wait3 2 , so on those systems time reports the majority of the resources as zero.
This is an already answered, old question.. It's good to have such simple tool for just taking a look before we start any serious profiling.
What are the units for the output of the memusg script? DanielStandage: probably in Kilobytes. The link to memusg given in the answer seems to be broken. Handy script, but I need sort -g on my Slackware system I presume you are looking for the highest value. Massif has a much higher overhead than time though, taking at least 10 times more time on a command like ls.
It is way too massive indeed. This answer should mention the slow down. The command I want to measure normally takes 35 seconds to complete. I don't know what to suggest. The code above is exactly what I got running a latex command that happened to be in history. As I say, more accurate results can be obtained with other tools. Deleteman: time is a built in command when using csh. If you use the exact path, it will allow you to run the external command. As far as I know, only the GNU version supports the format option. Maximum resident set size kbytes : Isn't this ground already covered by an answer added two years prior?
How to Dramatically Improve Your Short Term Memory In No Time
I get the same On Ubuntu I'm happy with it. I hope Mmax there means what we want it to mean The major drawback of this method is that if the process allocates much memory for a short period e. Reducing the sleep time may help a bit. I've literally spent an hour trying to get Instruments. Yes, command is not a placeholder, command time is different than just time. You just run it with the pid of the process you want to watch as the argument:!

Anterograde amnesia is when brain trauma curtails or stops someone's ability to form new memories. The most famous case study of anterograde amnesia is Henry Molaison , who in had parts of his brain removed as a last-ditch treatment for severe seizures.
While Molaison—known when he was alive as H.

People who worked with him for decades had to re-introduce themselves with every visit. By studying people such as H. It seems that short-term and long-term memories don't form in exactly the same way, nor do declarative and procedural memories. There's no one place within the brain that holds all of your memories; different areas of the brain form and store different kinds of memories, and different processes may be at play for each.
For instance, emotional responses such as fear reside in a brain region called the amygdala. Memories of the skills you've learned are associated with a different region called the striatum.

Since the s scientists have surmised that memories are held within groups of neurons, or nerve cells, called cell assemblies. Those interconnected cells fire as a group in response to a specific stimulus, whether it's your friend's face or the smell of freshly baked bread.
The more the neurons fire together, the more the cells' interconnections strengthen. That way, when a future stimulus triggers the cells, it's more likely that the whole assembly fires. The nerves' collective activity transcribes what we experience as a memory. Scientists are still working through the details of how it works. For a short-term memory to become a long-term memory, it must be strengthened for long-term storage, a process called memory consolidation.
Consolidation is thought to take place by several processes. One, called long-term potentiation, consists of individual nerves modifying themselves to grow and talk to their neighboring nerves differently. That remodeling alters the nerves' connections in the long term, which stabilizes the memory. All animals that have long-term memories use this same basic cellular machinery; scientists worked out the details of long-term potentiation by studying California sea slugs.
However, not all long-term memories necessarily have to start as short-term memories. As we recall a memory, many parts of our brain rapidly talk to each other, including regions in the brain's cortex that do high-level information processing, regions that handle our senses' raw inputs, and a region called the medial temporal lobe that seems to help coordinate the process. One recent study found that at the moment when patients recalled newly formed memories, ripples of nerve activity in the medial temporal lobe synced up with ripples in the brain's cortex.
Many mysteries of memory remain. How precisely are memories encoded within groups of neurons? How widely distributed in the brain are the cells that encode a given memory? How does our brain activity correspond to how we experience memories? These active areas of research may one day provide new insight into brain function and how to treat memory-related conditions.
If so, the act of remembering something makes that memory temporarily malleable—letting it be strengthened, weakened, or otherwise altered. Memories may be more easily targeted by medications during reconsolidation, which could help treat conditions such as post-traumatic stress disorder, or PTSD.
