ssd

问题 I have trained an SSD Mobilenet model with custom dataset(Battery). Sample image of the battery is given below and also attached the config file which I used to train the model. When the object is closer to the camera(tested with webcam) it detects the object accurately with probability over 0.95 but when I move the object to a longer distance it is not getting detected. Upon debugging, Found that the object gets detected but with the lower probability 0.35 . The minimum threshold is set to 0

问题 How can I, from a C program, read the hardware information of a drive? (I.e. to determine if the drive is an SSD or a mechanical disk.) 回答1: SSD are supposed to identify themselves as non-rotative. For linux, as example, you can get the info via sysfs: cat /sys/block/sda/queue/rotational If it returns 0, you have SSD... 回答2: Have you considered doing a read/write test to try to determine capabilities ? 回答3: You can use the GetDriveType Method from the win32 library, and you might be able to

问题 I need to access SSD drive with NASM 16-bit code. When accessing regular hard drive, need to set registers AX, DX, CX to choose Cylinder/Track/Sector/Number of sectors ( AH - to choose read sector function, DL - to choose drive number, CH - to choose cylinder, DH - to choose side on disk, CL - to choose sector on track, AL - to choose number of sectors). However, I suppose SSD disk has some other structure, so how to access them correctly? 回答1: Assuming translation of fake geometry into LBA

问题 I am working with NVMe card on linux(Ubuntu 14.04). I am finding some performance degradation for Intel NVMe card when formatted with xfs file system with its default sector size(512). or any other sector size less than 4096. In the experiment I formatted the card with xfs filesystem with default options. I tried running fio with 64k block size on an arm64 platform with 64k page size. This is the command used fio --rw=randread --bs=64k --ioengine=libaio --iodepth=8 --direct=1 --group

问题 I trained SSD using TensorFlow Object Detection API as described here. It produces a ckpt, meta and index file. In order to run it on my images I tried to check the demo code. It requires that the model be converted to frozen graph. I tried to convert my model to a frozen inference graph as described here. In that program I have to provide output node names. I could not figure out the name of the node in the SSD model which must be used here. Please help. I tried 'num_detections:0',

问题 Good post here says speed better with SSD drive for Eclipse work. But my slow part is mostly for maven builds. I have project with 1600+ classes. It take 2-3 min for a clean build with maven. I wonder if SSD drive will make it faster? Because SSD drive is big improvement on reads, but smaller improvement on writes as I understand. I wonder if anyone has experimented with this? 回答1: SSD write speed is slower than read speed but you don't have dsk access latency to pay, so will nearly always be

问题 I want to try to speed up my compile-time of our C++ projects. They have about 3M lines of code. Of course, I don't need to always compile every project, but sometimes there are lot of source files modified by others, and I need to recompile all of them (for example, when someone updates an ASN.1 source file). I've measured that compiling a mid-project (that does not involves all the source files) takes about three minutes. I know that's not too much, but sometimes it's really boring waiting

问题 In the following EC2 instance types which have SSD drives r3.2xlarge r3.4xlarge i2.xlarge When I login through SSH, I am unable to see the SSD drives. I was trying "df -h". I have tried reboot, but that did not help. tried to terminate and create a new instance that also does not help. Suggesting that its not one-off issue. 回答1: I found one solution by trying the steps suggested for adding EBS volumes to Ubuntu instnaces Below are my steps: sudo mkfs.ext4 /dev/xvdb sudo mkdir -m 000 /mnt #

问题 I would like to change the performance and behaviour of my C++ application, according to whether the system drive is an SSD or not. Example: With SSD, I want my gameserver application to load each map fully, with all objects in order to maximize performance. With HDD, I want my gameserver application to load only the essential objects and entities in each map, with no external objects loaded. I've seen http://msdn.microsoft.com/en-gb/library/windows/desktop/aa364939(v=vs.85).aspx, which is a
