Sadly these things rely heavily on the underlying OS, so there are no platform-independent calls. (Maybe there are some wrapper frameworks, but I don’t know of any.) On Linux you could have a look at the getrusage() function call, on Windows you can use GetProcessMemoryInfo() for RAM Usage. Have also a look at the other … Read more
So to prevent another dozen of answers suggesting invalid in the context of this thread suggestion to !kill -9 -1, let’s close this thread: The answer is simple: As of this writing Google simply gives only 5% of GPU to some of us, whereas 100% to the others. Period. dec-2019 update: The problem still exists … Read more
I’ve done some research and found a function to get the memory from Linux systems here: Determine free RAM in Python and I modified it a bit to set the memory hard limit to half of the free memory available. import resource import sys def memory_limit(): “””Limit max memory usage to half.””” soft, hard = … Read more
Python Object Data Size If the data is stored in some python object, there will be a little more data attached to the actual data in memory. This may be easily tested. It is interesting to note how, at first, the overhead of the python object is significant for small data, but quickly becomes negligible. … Read more
As of API level 16 you can now use the totalMem property of the MemoryInfo class. Like this: ActivityManager actManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); ActivityManager.MemoryInfo memInfo = new ActivityManager.MemoryInfo(); actManager.getMemoryInfo(memInfo); long totalMemory = memInfo.totalMem; Api level 15 and lower still requires to use the unix command as shown in cweiske’s answer.
On Linux, you can use the function sysinfo which sets values in the following struct: #include <sys/sysinfo.h> int sysinfo(struct sysinfo *info); struct sysinfo { long uptime; /* Seconds since boot */ unsigned long loads[3]; /* 1, 5, and 15 minute load averages */ unsigned long totalram; /* Total usable main memory size */ unsigned long … Read more
Yes, a 32-bit architecture is limited to addressing a maximum of 4 gigabytes of memory. Depending on the operating system, this number can be cut down even further due to reserved address space. This limitation can be removed on certain 32-bit architectures via the use of PAE (Physical Address Extension), but it must be supported … Read more
Use PHPSysInfo library phpSysInfo is a open source PHP script that displays information about the host being accessed. It will displays things like: Uptime CPU Memory SCSI, IDE, PCI Ethernet Floppy Video Information It directly parsed parses /proc and does not use exec. Another way is to use Linfo. It is a very fast cross-platform … Read more
del statement does not delete an instance, it merely deletes a name. When you do del i, you are deleting just the name i – but the instance is still bound to some other name, so it won’t be Garbage-Collected. If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all … Read more
MySQL’s maximum memory usage very much depends on hardware, your settings and the database itself. Hardware The hardware is the obvious part. The more RAM the merrier, faster disks ftw. Don’t believe those monthly or weekly news letters though. MySQL doesn’t scale linear – not even on Oracle hardware. It’s a little trickier than that. … Read more
